    (Relationships)
    Feeling dim. Watching and listening to many couples today. I just realized that besides men’s systematic and spatial bias, one of the reasons men focus on the external world is because women so thoroughly monopolize the internal world that they drive men out of it.
    Because single men do both. Married men avoid it. Men seek man caves or male spaces because women so thoroughly monopolize the internal (familial) spaces (it’s nesting behavior) that they drive men out of it into spaces where they have agency.
    Now, I don’t let this kind of thing happen because I’m too sensitive to my environment. So it’s more that I say ‘these spaces are mine, and those spaces are yours’. This means that I have space for my work and hobbies (meaning a desk in the living room), and space for entertaining (most of which is business related).

    Neoteny as a Foundational Framework: Understanding Intelligence, Aggression, and Self-Regulation

    The proposition that IQ functions as an effect rather than a cause offers a compelling reframing of human group differences through the lens of neoteny — the retention of juvenile characteristics into adulthood. This perspective suggests that intelligence represents just one manifestation of broader neotenic evolutionary patterns, while traits like impulsivity, aggression, and self-regulation may exert more powerful influences on behavior and development.

    Neoteny: The Underlying Developmental Framework

    Human evolution has been characterized by significant neotenic changes, particularly in brain development and behavioral patterns. Research demonstrates that the human brain exhibits transcriptional neoteny, with specific genes showing delayed expression patterns compared to other primates. This developmental retardation is most pronounced during early adolescence, coinciding with critical periods of prefrontal cortex maturation.pmc.ncbi.nlm.nih+1

    The neotenic process affects specific subsets of genes involved in neural development, rather than uniformly altering the entire transcriptome. This selective delay creates an extended period of neural plasticity, allowing for greater environmental influence and behavioral adaptability. Importantly, the neotenic shift particularly affects genes preferentially expressed in gray matter, corresponding to periods of substantial cortical reorganization.pmc.ncbi.nlm.nih+3

    Intelligence as an Emergent Property

    Evidence supports the view that intelligence emerges from broader developmental processes rather than serving as their primary driver. Studies reveal that individuals with higher IQ show prolonged environmental sensitivity into adolescence, resembling patterns typically seen in younger children. This extended sensitive period for intellectual development coincides with the neotenic delay in brain maturation.pmc.ncbi.nlm.nih

    The heritability of intelligence increases with age, rising from approximately 20% in infancy to potentially 80% in adulthood. However, this pattern masks complex gene-environment interactions that become increasingly important over time. Higher IQ individuals maintain child-like levels of environmental influence longer than their lower IQ counterparts, who shift earlier to adult-like genetic influence patterns.pmc.ncbi.nlm.nih+2

    Self-Regulation and Prefrontal Control Systems

    The development of self-regulatory mechanisms represents a critical aspect of neotenic evolution. The prefrontal cortex, central to impulse control and emotional regulation, undergoes protracted maturation extending well into young adulthood. This extended development period creates vulnerabilities to environmental influences but also enables sophisticated behavioral control systems to emerge.nature+1

    Effortful control, a temperament trait emerging in the first year of life, functions to regulate reactive aspects of behavior including fear and anger. Deficits in this system contribute significantly to early aggressive behavior and externalizing problems. The maturation of prefrontal-amygdala circuitry is particularly crucial, as this system forms the foundation for mature emotional regulation.pmc.ncbi.nlm.nih+1

    Aggression and Impulsivity: Primary Behavioral Drivers

    Research demonstrates that impulsivity and aggression may function as more fundamental behavioral drivers than intelligence. The neurobiology of impulsive aggression involves the acute threat response system, including the amygdala, hypothalamus, and periaqueductal gray. When prefrontal regulatory systems are compromised, behavior becomes more impulsive and potentially aggressive.pmc.ncbi.nlm.nih

    Aggressive behavior patterns established in early childhood often persist through development, with individual differences in self-regulation and social cognition playing crucial roles. Children with high levels of aggressive peer interactions show lower levels of self-regulation and delayed theory of mind understanding. These deficits appear more predictive of behavioral outcomes than raw intellectual capacity.pmc.ncbi.nlm.nih

    Developmental Timing and Group Differences

    The neotenic framework suggests that group differences may stem from variations in developmental timing rather than fixed intellectual capacities. Different populations may exhibit varying degrees of neotenic development, affecting the pace of prefrontal maturation and the duration of environmental sensitivity periods.

    Domesticated animals provide instructive examples of neoteny’s effects on behavior. Selection for juvenile behavioral characteristics leads to reduced aggression and increased tractability. Similar processes may have operated in human evolution, with neotenic changes facilitating cooperation and social cohesion while maintaining behavioral plasticity.wikipedia+1

    Environmental Sensitivity and Plasticity

    The extended period of environmental sensitivity associated with neoteny creates both opportunities and vulnerabilities. Early adversity can significantly impact the development of amygdala-prefrontal circuitry, affecting emotional regulation throughout life. However, this same plasticity enables remarkable adaptability to changing environmental conditions.pmc.ncbi.nlm.nih

    Gene-environment interactions become increasingly complex during neotenic development. Environmental factors such as family socioeconomic status, neighborhood characteristics, and educational opportunities can substantially influence cognitive and behavioral outcomes. The magnitude of these effects often exceeds purely genetic contributions, particularly during critical developmental periods.elifesciences+1

    Implications for Understanding Human Variation

    This neotenic framework has profound implications for understanding human group differences. Rather than focusing on intelligence as a primary explanatory factor, attention should shift to the developmental processes that give rise to various behavioral phenotypes. Variations in neotenic development may explain observed differences in:

    Impulse control and executive functioning
    Aggressive behavior patterns and emotional regulation
    Environmental sensitivity and learning capacity
    Social cooperation and behavioral flexibility

    The evidence suggests that impulsivity, aggression, and self-regulation may indeed be more influential than intelligence per se in determining life outcomes and group characteristics. These traits emerge from fundamental neotenic processes and exert cascading effects on social behavior, educational achievement, and adaptive functioning.

    Conclusion

    The reconceptualization of intelligence as an effect of neoteny rather than its cause provides a more comprehensive framework for understanding human behavioral variation. By focusing on the underlying developmental processes that shape multiple traits simultaneously, this approach offers deeper insights into the mechanisms driving group differences and individual variation. The extended plasticity period characteristic of human neoteny creates both the potential for remarkable adaptability and the vulnerability to environmental influences that shape behavioral phenotypes across populations.

    The Myth of Asian IQ Advantage (They work harder)

    1. Debunking the “Asian IQ Advantage”
    • James Flynn (of the Flynn Effect) recalculated inflated Japanese and Chinese-American IQ data:
      Japanese IQ drops from ~106 to ~99 when sample bias is corrected.
      Chinese-American IQ drops to 97 verbal / 100 nonverbal with updated tests.
    • This means Asian-American success has occurred despite slightly lower average IQ than whites, not because of higher IQ.
    2. Cultural Effort, Not IQ
    • East Asian students in the U.S. spend ~13 more hours per week on academics than white peers.
    • Academic advantage comes mainly from effort and cultural attitudes linking effort to achievement, not innate cognitive ability.
    • Immigration status contributes — many East Asians in the U.S. are from families self-selected for ambition, education, and risk-taking.
    3. Underrepresentation in Power
    • Despite educational success, Asians are underrepresented in corporate leadership, politics, and university presidencies.
    • Possible causes:
      DEI dynamics: Asians seen as “white-adjacent” in diversity politics.
      Specialization & verbal skills gap: Strength in math/spatial reasoning, weaker in verbal skills may hinder bureaucratic and political advancement.
      Cultural conformity (Confucianism): Emphasis on hierarchy and tradition may limit creativity and leadership competitiveness.
    4. Immigration & Bottleneck Effects
    • Many immigrant success patterns reflect recent selective migration, not general traits of the origin-country population.
    • Example: Cuban-Americans vs. Cubans in Cuba.
    • Example: Taiwan’s semiconductor dominance rooted in a selective migration of anti-communist elites and skilled workers.
    • Selection produces cultural and genetic clustering of ambition, risk tolerance, and competence.
    5. Class Over Ethnicity
    • Persistent class effects: Elites tend to re-emerge at the top even after forced class inversion (e.g., post-revolution China).
    • This suggests genetic and cultural inheritance of traits relevant to success, but these differences operate more strongly along class lines than ethnic lines.
    6. The “Offensive” Implication
    • If differences in group success aren’t explained by large IQ gaps or historical oppression, then:
      Culture (values, effort norms) matters far more.
      Selective immigration amplifies certain traits.
      Class advantages persist even through upheaval.
    • This undermines both racial-essentialist and simplistic systemic-oppression narratives.

    ( Human Aesthetics 😉 )
    One of the reasons I liked living in Ukraine and Russia was the daily experience of watching beautiful women and their children walk by. It’s like flowers. 😉
    And by that I mean natural beauty not ‘dolled up pretense’ reminding me of the lyrics “… secretaries primp and preen like cheap tarts on a red light street…”. Which is in my experience the east coast model.
    When the evidence of course is that men prefer the natural ‘you’ so to speak – and that you’re just not overweight.
    So, I’m sitting here in western washington, in a starbucks, in a wealthy semi-rural town, watching one natural, beautiful, woman after another come fetch her coffee.
    This area is known for the evasion of makeup. It’s also known for a lack of attractive women – which has changed as the tech industry has dominated and drawn the female interests like moths to the flame.
    Now, I’d intended to read some documentation on AI configuration but the distraction, while delaying both that effort and my concentration, is somehow a luxury I’m happy to experience.
    Unfortunately I remember american women before the fat-pocalypse, and the subsequent hatred of men. I remember when we liked each other.
    Even in the 70s. Which wasn’t exactly a time of economic comfort zones.
    I love mankind. It’s the rude individuals who either cannot or will not, or virtue signal they won’t, in a false pretense of superiority easily transparent, appreciate one another, and what we have achieved with one another, particularly in the west – an achievement few others have. And those who have did so in our imitation.
    And we live in an era where that achievement has been undermined through immigrants, and our women, both of whom favor the security of stagnation over the stress of innovative heroism.
    Hugs all.

    Pretty much.
    You know, even until recently, in “Traditional Family” models (basically latin), you weren’t considered an adult util you had children.
    Why? Because the locus of your responsibilty had not yet matured beyond yourself in any degree where personal sacrifice was necessary to maintain it.

    This is the familial version of only allowing people who have responsibility for employoment of family land non-family members in the owernship of land (farming, trading etc) in order for them to posses voting rights.

    And… both of those ‘limits’ on ‘influence’ are likely correct.

    It’s WAAAAAY worse for women, which is why we had one family one vote, and by the man, so that voting would be responsible.

    Women can develop male levels of CIVIL responsibility but it usually occurs after children and usually only after at least three. (Yeah, really). And sometimes not until they reach 40.

    Most female thought and speech isn’t worth the effort of listening to. The problem is that men can’t treat feels as reals any more than women can overcome feels to reason with reals. The interesting outcome of a century of pretending the sexes are equal or even close to the same is a vast self centeredness, particularly among women which is why men think more so now than ever that women are ridiculous self centered, attention seeking, stimulation seeking, hyperconsuming hypergamous, domesticated animals outside of nesting, child rearing, and small social groups. 🙁
    What a way to ruin ten thousand tears of putting women we love on a pedestal in just four generations. 🙁
    exasperated. It happened in my lifetime….
