    (FB 1542039089 Timestamp) by BobJohnsonIsRight The United States Government has extensively studied the concept of second American Civil War (along the assumption that it will be left versus right. HMM. I WONDER WHY THEY MIGHT POSSIBLY DO THAT.) Their conclusion is as follows: They don’t have a snowball’s chance in Hell of winning. The moment civil war is declared, the government loses. No scenario or outcome ends in their success. Period. It’s just a matter of how long it takes. A longer analysis will follow, but here are the salient points. 30% of the American population will actively revolt. This alone is enormous and damning. Historically, you only need 10% of the population to actively participate in a rebellion to successfully overthrow the establishment: We only had 15% of the population actively attempting to throw out the British during the Revolutionary War; roughly 70% of what remained was neutral and simply stood by. By contrast, 30% of Americans in modern America would support a revolution to stop their own government if it happened tomorrow That’s how discontent the people are and how much the people don’t support the government. The government would need infrastructure more than rebels would. Already working with significant handicaps, the establishment would need electricity, access to the Internet, bridges, and airports to coordinate any active campaign against the rebellion. By contrast, the rebellion can work in the dark. Considering how easy it would be to sabotage US infrastructure, one of the first things the rebellion would do is collapse bridges, destroy, or seize power plants, and cover the Interstate in IEDs. This is relatively simple to accomplish, and it would inflict enormous damage on the establishment’s ability to restore order. It would also cost an enormous amount of time and effort to fix any sabotage, because the establishment would need to provide military protection to any workers attempting to rebuild, which is a drain their active fighting personnel resources that they could not afford. Taking America in a land war is almost impossible. The United States is absolutely full of natural terrain chokepoints, making marching an army across it against armed resistance almost impossible, and it is large enough that no sustained air campaign would be possible. The Japanese Admiralty realized this themselves during WWII, which is why many of them were against attempting to invade. Also, by an interesting coincidence, most of those chokepoints are in hard conservative states, where the resistance would be strongest. The government would lack the ability to reclaim its own land by force, especially when the previous point about infrastructure is taken into account. President Lincoln, on the matter of potential European involvement in the first American Civil War, stated, “All the armies of Europe with a Bonaparte as a commander, could not take a drink from the Ohio.” A significant majority–between 55 and 70%–of the military would defect to the side of the citizens. The problem with suppressing the people with a military, that literature and fantasy tend to overlook or ignore, is that the military is the people, too. In order to get any military to fight their own, you first have to convince them that it is necessary to do so–that it is justified. The Communists also ran into this problem, but they overcame it with psychological conditioning and creating a dog-eat-dog atmosphere within the military. The American government having actively recruited people who are patriotic, practical, brave, who have civilian families, and having reinforced those values throughout their training process, lacks the ability to convince the majority of their fighting force to engage against their own people. The moment a civil war breaks out, over half of the American military will defect to the rebel side. They will bring military gear with them and, more dangerous, military training. lt only takes one Navy Seal or Army Ranger to potentially train hundreds of civilians into a dangerous resistance force. They’ve done it before, in other nations. You can be damn sure they can do it on their own home turf. But it gets better. At least 10% of the people who defect to the civilian side would not do so openly, and they would not abandon their posts. The moment a civil war starts, not only does America lose over half its military to the cause, but their own command structure will suddenly be infested with moles, plants, and “traitors.” There would be almost no way of knowing who is actually on their side and who is supporting the uprising. Worse yet, if one of those people happens to be the captain of one of the nuclear submarines on standby in dark water, the civil war is already lost before it even gets started. Russia has already publicly stated that it will support any rebellion in the United States against the established government and will send troops and aid to support the resistance. This is pretty self-explanatory. The last thing the government would need during a civil war is Russia breathing down its neck, but they would get exactly that. To supplement two-thirds of their own military leaving and civilians being trained by military elites, Spetsnaz would drop in and the resistance would get armor and air support from the only other nation on the planet that stands a decent chance of fighting us openly and winning. The media fearmongers because it’s profitable. The media, for all of its paid shillery, would give coverage of everything the resistance does because it is immensely profitable for them to do so. It would be guaranteed views. The only response the establishment would have would be to either allow it or order a total media blackout on the rebellion. Either way they lose, because both outcomes would awaken hundreds of thousands–if not millions–of people. We can only win on the media arena, and they can only lose. It’s merely a matter of what they think will minimize their losses. American civilians are armed and dangerous. In spite of all of the illegal attempts from the political left to disarm the American people, there are approximately 89 guns for every 100 Americans. Furthermore, we are one of the top three arms manufacturers on the planet (the others being Russia and France). The establishment would be in trouble even if their opponents were unarmed, but any rebellion of the people in America is, by definition, an armed one. They could be easily armed further by stealing weapons or even outright being given them by sympathetic interests (unsurprisingly, an overwhelming number of weapons manufacturers on American soil are deeply traditionalist, and the odds are good that many minor–and at least one major–would side with the rebels). The last resort Catch 22. The United States has an enormous stockpile of munitions and explosives, up to and including a massive number of nuclear warheads. But they cannot use any of this in this Civil War. The establishment has to play a game of “we’re the good guys” with the rest of the world while this is all taking place. There will be lines they cannot cross, because to do so would elevate the issue from being an internal matter to an international one. The moment they throw an ICBM at Ohio or drop a nuke on Austin, Texas, it stops being a civil war and becomes an international relief effort where the other militaries of the other first world nations come to save the American people from their own out-of-control and tyrannical government. The rebellion, meanwhile, is not nearly so limited re: the hypothetical nuclear submarine captain. The rebels could threaten–without bluffing–to nuke Washington DC, but the establishment has no equivalent threat they could return.

If there was a revolution in the US, the rest of the world would get involved, fast. Depending on the type of uprising, there is a large chance that it would not be a quick affair. It would be brutal, it would be bloody, and the US government could start a global scale war. Here are the top ten issues that came up. The US power grid can be taken down by a series of “surgical strikes” with the exception of the Texas grid. By surgical strikes, I mean a few marksmen (US army-tier Marksmen–the minimum requirement) hitting certain spots on the grid would fuck a lot of the military and government because they need the grid more than Bubba and his friends do. Additionally, while all government agencies have backup generators, they will be hard pressed dealing with the resultant looting and other madness that would come with power outages. This would effectively create another front for the military. It would also turn the people against the government more quickly and paralyze the government’s propaganda machine. Worse still–the key points of the US power grid are publicly obtainable information, and not only are the points too many to be effectively guarded, they are not guarded anyway. The estimated desertion rate in case of a civil war is 75% in the case of a left-wing president. 50% of that would be assumed to immediately betray the president. The remaining (treasonous) military would be fighting its own. Yet another front created in the war. Additionally, there is an assumed 25-50% desertion or outright betrayal rate in three letter government agencies (FBI, CIA, NSA, ATC, TSA, etc.). Additionally, it is assumed that 5% of the initial 50% betrayers would stay in their job and become saboteurs. 10% of that 50% would contain key information that would be of critical danger to the US government. Of that 10%, 1% would be able to deliver that information to the US’ foreign enemies. What you should get from this is that the second the United States government declares war on its own is the second it ceases to exist as the state we know it. “Tea baggers,” “right-wing extremists,” and “oath keepers” which are considered untrained racists who aren’t “good with a gun” often are A) veterans who now have more time to have fun at the range, sometimes more than some Army units or Marine units. In addition to previous military training, B) often camp and do other outdoor activities–more than many in the military do, as the focus has gone away from field exercises, and C) often have better equipment–outside of armor and heavy weapons–than the military. However, C) is kind of irrelevant because many of the places in which these people could hide would make the kind of war the US fights with the equipment they use pointless. Outside influence is a huge problem. Russia has already stated they would back a Texas separatist movement, and right now we already have enough problem keeping Islam in check. The second the US has to fight in a “civil war” is the second it becomes a proxy war between NATO and whoever wants to mess with America. While America has amazing nuclear and air defense, if it comes to a civil war you have to assume that in a best cast scenario the US military is going to be operating at 50% capacity at best. Shit would go down. Hard. And fast. And if Russia–spoiler alert: one of the best militaries in the world at fighting in an urban environment–sent trainers and helpers to rebels, you can reliably bet that they would also possibly deliver weapons to them. So instead of fighting “Timmy TeaBagger,” you are fighting “Timmy TeaBagger who is buddies with Vlad.” A civil war is not just the US versus the rebels. There will be looting. There will be rioting. Cities will burn. The National Guard cannot fight both the rebels and rioters in a city that would also cut off their supplies. Additionally, if you don’t think that the rebels will send in instigators into the cities–or worse, stand alone actors (A Lone Wolf on steroids. Think Timothy McVeigh, but instead of one van they have a whole fleet of them. A good movie example would be Bane)–you would be mistaken. If the US government cannot even help its own people, why would its own people support the remaining (treasonous) military? Worse yet, if someone emptied out prisons (There are more prisoners in the US than there are people in the entire Chinese Army), you would have more crime than the police could ever handle. Logistics and infrastructure in the US are crumbling and failing. Any war fought against a rebellion in the US would be a logistical nightmare, even before the rebels started going full Al-Qaida and putting IEDs in the road. A retired general who was contracting with us on the team said, “The only thing holding together the US’ infrastructure is duct tape and the will of the Department of Transportation. And often enough, there isn’t enough duct tape.” Your most loyal cities to the US government, as we polled, are also the most logistically easy to cut off. NYC? San Fran? L.A.? D.C.? Baltimore? Most of them require crossing water to enter, from certain directions. Most of them have critical airports. Some of them have critical ocean ports. If anything happened to just TWO of the cities on the list, it would create a logistical clusterfuck. Your “Johnny Reb” and “Timmy TeaBagger” states (i.e., “red” states) all have something most of your “oh so progressive,” “Aren’t we so European,” “Oh my god, we are just like Sweden,” blue states don’t. Blues are mainly consumer states. Reds are producer states. Urban areas don’t have farms. The second that shit goes down, realize a lot of those blue areas are likely to starve. In a civil war scenario, we predicted that at least 10,000 people would die of starvation if the war was not finished in a year. The numbers get worse after that. Or better, rather, for the country after the war. The US has way too many choke points, and the government forces would often be on the wrong side of them. This ties into the logistical nightmare, but it also has to do with an odd phenomena. Liberals like to live near the ocean. Many of the dividers of the country, like the Rocky Mountains, the Mississippi River, Appalachia, the Missouri River (fun fact: the biggest choke point for the US government is in Missouri) are red state areas. Sure, air travel is a thing, but a majority of the US government’s needs would have to travel by ground. Even still, many of the major airports are outside of the city. Of course, the US would use military base air fields, but if civil war did break out… which bases would be safe? Which ones would have fallen to the deserters? PR Nightmare. Every rebel killed on CNN would be spun as “the US government killed X Civilians today in a strike” on foreign news and pirate media not owned by the government. That is–as pointed out earlier–if the US media could even function in a civil war or uprising. Your “rebel scum” know that the main thing that holds together the US–nay life in the US as we know it–is the 24 hour news cycle and the media. The second it’s gone, you are going to have urban anarchy. If you are from America, can you imagine a day without TV, newspaper, or Internet? Your average urban youth can’t. If you don’t think that isn’t going to cause rioting, you must have a real high regard for how much restraint they have. Assume in a civil war that your ability to talk to the people is compromised. Also assume that in the case of a civil war that rebels may know how to monitor conversations like the US does, as there are manuals online on how to do so. This one is either 1 or 10, depending on who is asked. The US will never nuke its own. The second it does, they have lost the civil war and other countries will come to “liberate” the US from its own “repressive regime.” Additionally, if any general, minuteman, nuke tech, or nuke sub captain decided to side with the rebellion, the US government is immediately SOL. In short: The second that a “civilian uprising” or “extremist group terrorist attack” turns into “civil war” is the second the US loses. As a result, you will never see a civil war. You will see Waco, you will see Bundy Ranch, you will see all sorts of militant group confrontations and maybe even some skirmishes. But the US government fears its own people way the fuck too much to ever start a civil war. As an American, I want all other Americans here to remember this. The government is against you, almost openly now, but they also know that they cannot win if it comes to open war. We have a trump card they cannot match. If it comes to a fight, THEY WILL LOSE, so there are elements in the establishment who will do absolutely everything in their power to prevent it from coming to that. The US Government is not in support of its people, and the people are not in support of the government. It is within the means of certain interests to start World War III simply as a distraction to avoid an American Civil War, because, by their reckoning, it is better to ruin other “lesser” nations like Syria and spill the blood of patriots than lose their own grip on power. YOU HEARD RIGHT. WORLD WAR III ITSELF COULD BE A DELIBERATE FALSE FLAG TO PREVENT A POWER CHANGE IN AMERICA. REMEMBER THIS. Share Report Save Give gold

    (FB 1542572175 Timestamp) —“Humans intuit and organize as packs and herds, mixed as together as one. Women intuitively construct a herd. Men intuitively construct a pack. Polygamy is the crudest solution of this competition between pack and herd –monogamy the ultimate balance of pack and herd. Monogamy (pairing off) is the optimum nash equilibrium possible – no individual has his or her optimum but together they have the optimum for all.”—Michael D. Abbott I’ll augment that a bit in that packs of men domesticated herds of females before they domesticated herds of other herd animals, and partnered with wolves(dogs), who are the other pack animals. The fact that women have always been property of males offset by the care of fathers and brothers for their daughters (once they understood such a thing) is antithetical to the modern mind, but it is the reason females still demonstrate herd instincts as prey and males still demonstrate pack instincts as predators, and why civil societies form marriages as the means of satisfying the demands of both.

    (FB 1542640445 Timestamp) JOHN MARK’S JOURNEY TO LEADERSHIP By John Mark —“John Mark, You’ve made extraordinary progress coming seemingly out of nowhere and rapidly into thought leadership. For the sake of others, can you explain your journey, how long it took, and what advantages you had, and disadvantages you had to overcome? “—Curt Doolittle Thank you Curt. I’d be happy to share. First, I don’t know how to express how grateful I am to have come across you and this community of outstanding quality men (and some great women too). I started as a very motivated Christian. Grandparents and parents missionaries. High empathy gene. I just wanted to help people. Out of this grew a desire to understand truth. Somehow I realized this was the best way to help people in the long run. Started questioning certain commonly taught Christian doctrines (tithing), realized I’d been lied to. Then questioned hell (loving God + hell = does not compute). Spent a couple years researching it in the Bible. Wrote 500-pg book about it, got a niche audience online but couldn’t monetize it enough to be worth it. Also got very frustrated with church people. They punish questioning. I didn’t understand IQ, didn’t know that most of the people I was trying to talk to are practically a different species. Always had right wing economic instinct but almost no political knowledge. Started studying money, figured out banking scam. Got into conspiracy stuff. Then discovered “game”, redpilled on women. Then started trying to figure out the Left, because I truly could not understand them. I thought they could not possibly be sincere. (Now I know they are. At least the grassroots is. I did not fully realize this til I found Curt. Even many of the leaders – e.g. Obama probably is a true believer.) Abandoned the church. Realized the Bible does not inform about too many essential facts or equip how to solve political problems. Ended up stuck in a place where I couldn’t figure out how to stop the cycle of corruption/left advance. Somehow came across Curt, maybe 1.5 years ago (maybe 2?). Found the answer (Propertarianism) and took my understanding to a level I would not have thought possible. Have been feeding on Curt’s feed daily since I found him. I have also learned a lot from many others that contribute in his orbit. Everything I learned previously dovetailed in. From beginning to end, 10 years. Spending most of my “free time” studying/learning. I also learn by trying to teach, even if to myself. Writing, speaking, I teach out loud in the shower and in my bedroom. I record messages/content and listen back. Exposes my gaps. If I can’t explain it to a 12-yr-old, I don’t understand it well enough. And if I can’t predict accurately, I don’t understand. And if I can’t teach/speak decently on a subject off the cuff, I haven’t absorbed it well enough. (I do structure my content, but often stream of consciousness takes over due to familiarity with concepts, mulling them over for years. Often I get insights in the middle of speaking or writing. I’m sure Curt and many others have experienced this.) I did not try to come out with any political content until I was reasonably confident I had something to offer and that I would be more help than hindrance. I’m terrified of being wrong and leading people astray. (KEEP ME HONEST AND ACCURATE EVERYBODY!) I started by experimenting with short comments on Curt posts. Feedback was good so I kept going. I’ve always felt I had potential as a “teacher/explainer”/public speaker politically, but you never know until you test. Feedback was good enough from Curt and his group that I decided to start YouTube channel. Disadvantages:

    • Religious background, religious “experiences” I can’t explain. (Hinders scientific thought, wasted a lot of time seeking something unreliable.) A lot of muscle memory to undo.
    • Parents were loving (great in most ways) but did not prepare me for the real world. Struggled mightily in my 20s financially and with women (bluepilled) despite being tall, decent-looking, and naturally alpha in some ways. (This was an advantage in the end because it drove me to learn – “What am I doing wrong?”)
    • Extremely high creativity (musician), low conscientiousness naturally. Had to learn conscientiousness.
    • I don’t care about anything but my immediate family and understanding the world to help my people. This is an advantage but it’s like pulling teeth to get myself to work on my career. Make 6 figs now for big company doing mental/comms work but took me a while. Good socially but I’m not motivated to network with normies.
    • Zero support – nothing but rejection – from everyone I knew in meat world throughout my entire growth process. (I’m sure many others share this experience.)
    • No detailed historical knowledge, never studied philosophy or economics. Never got heavily into Libertarianism or Classical Liberalism. My time for studying was limited by workday and family, so I was laser-focused on “explain how the world works and why, or you’re wasting my time”. Every time I’d dip my toe into philosophy or econ I got frustrated. These things require sorting through huge volume of fluff/distraction and extracting nuggets and synthesizing, I simply didn’t have the time.

    Advantages:

    • Curt has been my shortcut on philosophy/econ/synthesis of everything – forever grateful. Curt also helped me realize that talking/preaching to people is not enough to get them to act productively, because it cannot overcome powerful instincts operating in millions of people. There must be rule of law (force) applied. (I kind of bypassed the libertarianism/classical liberal trap because Curt gave me a shortcut on so many subjects.)
    • 135-140ish IQ, skewed verbal. I can tell Curt and some/many men in Curt’s orbit are smarter than I am, but my range may be ideal for speaking to normies.
    • Extremely high openness (Big 5), learning is a compulsion, not a chore
    • Sitting in thousands of church services I learned the power of public speaking. Learned by observing. Contrasting the intolerable speakers from the great ones. T.D. Jakes (black preacher) + actual facts would be near perfection. I’m still improving but that volume of observation experience was helpful. Speak in simple language, be easy to follow (structure, or must be riveting if stream of consciousness), be genuine (don’t try to fake a persona) and passionate, explain why what you’re saying is important, surprise people somehow if you can, have a fresh angle of some sort that people haven’t heard before (even if it’s a new way of saying something that’s been said before). Listen to recordings of yourself – brutal but necessary to remove flaws/bad habits. What you hear on YouTube is somewhat edited for faster speed/pace (less captive audience than real life). Still trying to get better.
    • Got some decent experience public speaking in church settings. Enough to test and learn. A lot to youth. If you can keep 16-yr-olds interested for half an hour, you’re doing ok.
    • Am extremely comfortable in front of people due to playing music on stage (churches, other venues) hundreds/thousands of times.

    One big advantage: An amazing traditional, highly conscientious wife (Eastern European) who follows me everywhere intellectually and physically, is immune to leftist thought due to close knowledge of the effects of communism, and is a great cook! Hope this is helpful. Would be happy to answer any more specific questions. It is an amazing privilege to be a part of this. It’s bigger than any one of us and we all play our part. I hope to play mine with excellence to the best of my ability. Also a huge thank you to all of you who have encouraged me and given me your feedback and thoughts with the YouTube channel. Hugs

The results supported several conclusions. First, late childhood and adolescence were key periods. Across these years, age trends for some traits (a) were especially pronounced, (b) were in a direction different from the corresponding adult trends, or (c) first indicated the presence of gender differences. Second, there were some negative trends in psychosocial maturity from late childhood into adolescence, whereas adult trends were overwhelmingly in the direction of greater maturity and adjustment. Third, the related but distinguishable facet traits within each broad Big Five domain often showed distinct age trends, highlighting the importance of facet-level research for understanding life span age differences in personality.”— https://www.ncbi.nlm.nih.gov/pubmed/21171787/ Gender Differences in Personality across the Ten Aspects of the Big Five –“This paper investigates gender differences in personality traits, both at the level of the Big Five and at the sublevel of two aspects within each Big Five domain. Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men. However, more extensive gender differences were found at the level of the aspects, with significant gender differences appearing in both aspects of every Big Five trait. For Extraversion, Openness, and Conscientiousness, the gender differences were found to diverge at the aspect level, rendering them either small or undetectable at the Big Five level. These findings clarify the nature of gender differences in personality and highlight the utility of measuring personality at the aspect level.”— https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3149680/ Gender differences in personality traits across cultures: Robust and surprising findings. Costa Jr., Paul T.,Terracciano, Antonio,McCrae, Robert R. Journal of Personality and Social Psychology, Vol 81(2), Aug 2001, 322-331 —“Secondary analyses of Revised NEO Personality inventory data from 26 cultures (N =23,031) suggest that gender differences are small relative to individual variation within genders; differences are replicated across cultures for both college-age and adult samples, and differences are broadly consistent with gender stereotypes: Women reported themselves to be higher in Neuroticism, Agreeableness, Warmth, and Openness to Feelings, whereas men were higher in Assertiveness and Openness to Ideas. Contrary to predictions from evolutionary theory, the magnitude of gender differences varied across cultures. Contrary to predictions from the social role model, gender differences were most pronounced in European and American cultures in which traditional sex roles are minimized. Possible explanations for this surprising finding are discussed, including the attribution of masculine and feminine behaviors to roles rather than traits in traditional cultures.

Journal of Personality and Social Psychology, Vol 93(5), Nov 2007, 880-896 –“Factor analyses of 75 facet scales from 2 major Big Five inventories, in the Eugene-Springfield community sample (N=481), produced a 2-factor solution for the 15 facets in each domain. These findings indicate the existence of 2 distinct (but correlated) aspects within each of the Big Five, representing an intermediate level of personality structure between facets and domains. The authors characterized these factors in detail at the item level by correlating factor scores with the International Personality Item Pool (L. R. Goldberg, 1999). These correlations allowed the construction of a 100-item measure of the 10 factors (the Big Five Aspect Scales [BFAS]), which was validated in a 2nd sample (N=480). Finally, the authors examined the correlations of the 10 factors with scores derived from 10 genetic factors that a previous study identified underlying the shared variance among the Revised NEO Personality Inventory facets (K. L. Jang et al., 2002). The correspondence was strong enough to suggest that the 10 aspects of the Big Five may have distinct biological substrates.

Sex differences in Big Five personality traits across 55 cultures. —“Previous research suggested that sex differences in personality traits are larger in prosperous, healthy, and egalitarian cultures in which women have more opportunities equal with those of men. In this article, the authors report cross-cultural findings in which this unintuitive result was replicated across samples from 55 nations (N = 17,637). On responses to the Big Five Inventory, women reported higher levels of neuroticism, extraversion, agreeableness, and conscientiousness than did men across most nations. These findings converge with previous studies in which different Big Five measures and more limited samples of nations were used. Overall, higher levels of human development–including long and healthy life, equal access to knowledge and education, and economic wealth–were the main nation-level predictors of larger sex differences in personality. Changes in men’s personality traits appeared to be the primary cause of sex difference variation across cultures. It is proposed that heightened levels of sexual dimorphism result from personality traits of men and women being less constrained and more able to naturally diverge in developed nations. In less fortunate social and economic conditions, innate personality differences between men and women may be attenuated.”— PMID: 18179326 DOI: 10.1037/0022-3514.94.1.168 Higher-order factors of the Big Five in a multi-informant sample. DeYoung, Colin G. Journal of Personality and Social Psychology, Vol 91(6), Dec 2006, 1138-1151 —“In a large community sample (N=490), the Big Five were not orthogonal when modeled as latent variables representing the shared variance of reports from 4 different informants. Additionally, the standard higher-order factor structure was present in latent space: Neuroticism (reversed), Agreeableness, and Conscientiousness formed one factor, labeled Stability, and Extraversion and Openness/Intellect formed a second factor, labeled Plasticity. Comparison of two instruments, the Big Five Inventory and the Mini-Markers, supported the hypotheses that single-adjective rating instruments are likely to yield lower interrater agreement than phrase rating instruments and that lower interrater agreement is associated with weaker correlations among the Big Five and a less coherent higher-order factor structure. In conclusion, an interpretation of the higher-order factors is discussed, including possible neurobiological substrates.

Kelly EL, Conley JJ. —The antecedents of marital stability (divorce or remaining married) and marital satisfaction (within the group that remains married) were investigated with a panel of 300 couples who were followed from their engagements in the 1930s until 1980. Twenty-two of the couples broke their engagements; of the 278 couples who married, 50 got divorced at some time between 1935 and 1980. Personality characteristics (measured by acquaintance ratings made in the 1930s) were important predictors of both marital stability and marital satisfaction. The three aspects of personality most strongly related to marital outcome were the neuroticism of the husband, the neuroticism of the wife, and the impulse control of the husband.

The evolution of sex role divergence is widely attributed to anisogamy initiating a self‐reinforcing process. The initial asymmetry in pre‐mating parental investment (eggs vs. sperm) is assumed to promote even greater divergence in post‐mating parental investment (parental care). But do we really understand the process? Trivers [Sexual Selection and the Descent of Man 1871–1971 (1972), Aldine Press, Chicago] introduced two arguments with a female and male perspective on whether to care for offspring that try to link pre‐mating and post‐mating investment. Here we review their merits and subsequent theoretical developments. The first argument is that females are more committed than males to providing care because they stand to lose a greater initial investment. This, however, commits the ‘Concorde Fallacy’ as optimal decisions should depend on future pay‐offs not past costs. Although the argument can be rephrased in terms of residual reproductive value when past investment affects future pay‐offs, it remains weak. The factors likely to change future pay‐offs seem to work against females providing more care than males. The second argument takes the reasonable premise that anisogamy produces a male‐biased operational sex ratio (OSR) leading to males competing for mates. Male care is then predicted to be less likely to evolve as it consumes resources that could otherwise be used to increase competitiveness. However, given each offspring has precisely two genetic parents (the Fisher condition), a biased OSR generates frequency‐dependent selection, analogous to Fisherian sex ratio selection, that favours increased parental investment by whichever sex faces more intense competition. Sex role divergence is therefore still an evolutionary conundrum. Here we review some possible solutions. Factors that promote conventional sex roles are sexual selection on males (but non‐random variance in male mating success must be high to override the Fisher condition), loss of paternity because of female multiple mating or group spawning and patterns of mortality that generate female‐biased adult sex ratios (ASR). We present an integrative model that shows how these factors interact to generate sex roles. We emphasize the need to distinguish between the ASR and the operational sex ratio (OSR). If mortality is higher when caring than competing this diminishes the likelihood of sex role divergence because this strongly limits the mating success of the earlier deserting sex. We illustrate this in a model where a change in relative mortality rates while caring and competing generates a shift from a mammalian type breeding system (female‐only care, male‐biased OSR and female‐biased ASR) to an avian type system (biparental care and a male‐biased OSR and ASR).”—

The results supported several conclusions. First, late childhood and adolescence were key periods. Across these years, age trends for some traits (a) were especially pronounced, (b) were in a direction different from the corresponding adult trends, or (c) first indicated the presence of gender differences. Second, there were some negative trends in psychosocial maturity from late childhood into adolescence, whereas adult trends were overwhelmingly in the direction of greater maturity and adjustment. Third, the related but distinguishable facet traits within each broad Big Five domain often showed distinct age trends, highlighting the importance of facet-level research for understanding life span age differences in personality.”— https://www.ncbi.nlm.nih.gov/pubmed/21171787/ Gender Differences in Personality across the Ten Aspects of the Big Five –“This paper investigates gender differences in personality traits, both at the level of the Big Five and at the sublevel of two aspects within each Big Five domain. Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men. However, more extensive gender differences were found at the level of the aspects, with significant gender differences appearing in both aspects of every Big Five trait. For Extraversion, Openness, and Conscientiousness, the gender differences were found to diverge at the aspect level, rendering them either small or undetectable at the Big Five level. These findings clarify the nature of gender differences in personality and highlight the utility of measuring personality at the aspect level.”— https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3149680/ Gender differences in personality traits across cultures: Robust and surprising findings. Costa Jr., Paul T.,Terracciano, Antonio,McCrae, Robert R. Journal of Personality and Social Psychology, Vol 81(2), Aug 2001, 322-331 —“Secondary analyses of Revised NEO Personality inventory data from 26 cultures (N =23,031) suggest that gender differences are small relative to individual variation within genders; differences are replicated across cultures for both college-age and adult samples, and differences are broadly consistent with gender stereotypes: Women reported themselves to be higher in Neuroticism, Agreeableness, Warmth, and Openness to Feelings, whereas men were higher in Assertiveness and Openness to Ideas. Contrary to predictions from evolutionary theory, the magnitude of gender differences varied across cultures. Contrary to predictions from the social role model, gender differences were most pronounced in European and American cultures in which traditional sex roles are minimized. Possible explanations for this surprising finding are discussed, including the attribution of masculine and feminine behaviors to roles rather than traits in traditional cultures.

Journal of Personality and Social Psychology, Vol 93(5), Nov 2007, 880-896 –“Factor analyses of 75 facet scales from 2 major Big Five inventories, in the Eugene-Springfield community sample (N=481), produced a 2-factor solution for the 15 facets in each domain. These findings indicate the existence of 2 distinct (but correlated) aspects within each of the Big Five, representing an intermediate level of personality structure between facets and domains. The authors characterized these factors in detail at the item level by correlating factor scores with the International Personality Item Pool (L. R. Goldberg, 1999). These correlations allowed the construction of a 100-item measure of the 10 factors (the Big Five Aspect Scales [BFAS]), which was validated in a 2nd sample (N=480). Finally, the authors examined the correlations of the 10 factors with scores derived from 10 genetic factors that a previous study identified underlying the shared variance among the Revised NEO Personality Inventory facets (K. L. Jang et al., 2002). The correspondence was strong enough to suggest that the 10 aspects of the Big Five may have distinct biological substrates.

Sex differences in Big Five personality traits across 55 cultures. —“Previous research suggested that sex differences in personality traits are larger in prosperous, healthy, and egalitarian cultures in which women have more opportunities equal with those of men. In this article, the authors report cross-cultural findings in which this unintuitive result was replicated across samples from 55 nations (N = 17,637). On responses to the Big Five Inventory, women reported higher levels of neuroticism, extraversion, agreeableness, and conscientiousness than did men across most nations. These findings converge with previous studies in which different Big Five measures and more limited samples of nations were used. Overall, higher levels of human development–including long and healthy life, equal access to knowledge and education, and economic wealth–were the main nation-level predictors of larger sex differences in personality. Changes in men’s personality traits appeared to be the primary cause of sex difference variation across cultures. It is proposed that heightened levels of sexual dimorphism result from personality traits of men and women being less constrained and more able to naturally diverge in developed nations. In less fortunate social and economic conditions, innate personality differences between men and women may be attenuated.”— PMID: 18179326 DOI: 10.1037/0022-3514.94.1.168 Higher-order factors of the Big Five in a multi-informant sample. DeYoung, Colin G. Journal of Personality and Social Psychology, Vol 91(6), Dec 2006, 1138-1151 —“In a large community sample (N=490), the Big Five were not orthogonal when modeled as latent variables representing the shared variance of reports from 4 different informants. Additionally, the standard higher-order factor structure was present in latent space: Neuroticism (reversed), Agreeableness, and Conscientiousness formed one factor, labeled Stability, and Extraversion and Openness/Intellect formed a second factor, labeled Plasticity. Comparison of two instruments, the Big Five Inventory and the Mini-Markers, supported the hypotheses that single-adjective rating instruments are likely to yield lower interrater agreement than phrase rating instruments and that lower interrater agreement is associated with weaker correlations among the Big Five and a less coherent higher-order factor structure. In conclusion, an interpretation of the higher-order factors is discussed, including possible neurobiological substrates.

Kelly EL, Conley JJ. —The antecedents of marital stability (divorce or remaining married) and marital satisfaction (within the group that remains married) were investigated with a panel of 300 couples who were followed from their engagements in the 1930s until 1980. Twenty-two of the couples broke their engagements; of the 278 couples who married, 50 got divorced at some time between 1935 and 1980. Personality characteristics (measured by acquaintance ratings made in the 1930s) were important predictors of both marital stability and marital satisfaction. The three aspects of personality most strongly related to marital outcome were the neuroticism of the husband, the neuroticism of the wife, and the impulse control of the husband. In combination, the 17 major antecedent variables were moderately predictive of a criterion variable composed of both marital stability and marital satisfaction (R = .49). The three major aspects of personality accounted for more than half of the predictable variance.

    (FB 1544804133 Timestamp) by Robin Helweg-Larsen About 177 AD the Greek philosopher Celsus, in his book ‘The True Word’, expressed what appears to have been the consensus Jewish opinion about Jesus, that his father was a Roman soldier called Pantera. ‘Pantera’ means Panther and was a fairly common name among Roman soldiers. The rumor is repeated in the Talmud and in medieval Jewish writings where Jesus is referred to as “Yeshu ben Pantera”. In 1859 a gravestone surfaced in Germany for a Roman soldier called Tiberius Iulius Abdes Pantera, whose unit Cohors I Sagittariorum had served in Judea before Germany – romantic historians have hypothesized this to be Jesus’ father, especially as ‘Abdes’ (‘servant of God’) suggests a Jewish background. Tib(erius) Iul(ius) Abdes Pantera Sidonia ann(orum) LXII stipen(diorum) XXXX miles exs(ignifer?) coh(orte) I sagittariorum h(ic) s(itus) e(st) Tiberius Iulius Abdes Pantera from Sidon, aged 62 years served 40 years, former standard bearer (?) of the First Cohort of Archers lies here The gravestone is now in the Römerhalle museum in Bad Kreuznach, Germany. It appears this First Cohort of Archers moved from Palestine to Dalmatia in 6 AD, and to the Rhine in 9 AD. Pantera came from Sidon, on the coast of Phoenicia just west of Galilee, presumably enlisted locally. He served in the army for 40 years until some time in the reign of Tiberius. On discharge he would have been granted citizenship by the Emperor (and been granted freedom if he had formerly been a slave), and added the Emperor’s name to his own. Tiberius ruled from 14 AD to 37 AD. Pantera’s 40 years of service would therefore have started between 27 BC and 4 BC. As Pantera would probably have been about 18 when he enlisted, it means he was likely born between 45 BC and 22 BC. He could have been as old as 38 or as young as 15 at the time of Jesus’ conception in the summer of 7 BC. In 6 AD when Jesus was 12, Judas of Galilee led a popular uprising that captured Sepphoris, the capital of Galilee. The uprising was crushed by the Romans some four miles north of Nazareth. It is possible (and appealing to lovers of historical irony) that Pantera and Joseph fought on opposite sides. As Joseph is never heard of again he may well have been killed in the battle, or have been among the 2,000 Jewish rebels crucified afterwards. So Tiberius Iulius Abdes Pantera is indeed a possibility as Jesus’ father. The only thing we know for certain is that Mary’s husband Joseph wasn’t the father, and that Mary was already pregnant when they married.
