    DYSGENICS IN THE USA AND UK REAL DECLINE IS 1.23/DECADE

    Woodley, Michael A. (2015). “How fragile is our intellect? Estimating losses in general intelligence due to both selection and mutation accumulation”. Personality and Individual Differences. 75: 80–84. doi:10.1016/j.paid.2014.10.047.

    HIGHLIGHTS
    •g Losses due to dysgenic selection in nine US and UK studies are meta-analyzed.
    •A decline of .39 points per decade is found.
    •Mutation load should enhance losses due to selection.
    •Each year of paternal age adds 2 new mutations and reduces offspring g by .084 points.
    •Combining selection and mutation losses reveals decadal g decline of 1.23 points.

    ABSTRACT
    Two dysgenic models of declining general intelligence have been proposed. The first posits that since the Industrial Revolution those with low g have had a reproductive advantage over those with high g. The second posits that relaxed purifying selection against deleterious mutations in modern populations has led to g declining due to mutation accumulation. Here, a meta-analytic estimate of the decline due to selection is computed across nine US and UK studies, revealing a loss of .39 points per decade (combined N = 202,924). By combining findings from a high-precision study of the effects of paternal age on offspring g with a study of paternal age and offspring de novo mutation numbers, it is proposed that, 70 de novo mutations per familial generation should reduce offspring g by 2.94 points, or .84 points per decade. Combining the selection and mutation accumulation losses yields a potential overall dysgenic loss of 1.23 points per decade, with upper and lower bound values ranging from 1.92 to .53 points per decade. This estimate is close to those from studies employing the secular slowing of simple reaction time as a potential indicator of declining g, consistent with predictions that mutation accumulation may play a role in these findings.

    “WHAT IS (g) OR GENERAL INTELLIGENCE?”

    1. g is a measure of comparative rate of learning, or more correctly rate of information processing.
    2. while humans demonstrate something like 80 capabilities, all abilities scale with g.
    3. the only substantive variation is the masculine (spatial- symbolic) with the feminine ( verbal-empathic). Not that they do not also scale with g (they do), but that there is value to be had in distinguishing the ratio of verbal and spatial – which is why our SAT’s etc are graded as such (and why tests have been modified to give women an advantage,by lowering the mathematical demands)>
    4. we measure g on a distribution with 100 being the average.
    5. to compensate for age differences we divide by the age.
    6. we update the tests to maintain the average (this is bad, it creates the same problem in intelligence measurement as prices so without reflecting purchasing power parity)
    7. we call this the IQ score. Intelligence quotient.
    8. we could calculate the g-score against a consistent measure (say 1970, at which point we had pretty consistent data). And separately publish the distribution by age bracket. so you would know your percentile for your peer group. This would be the most accurate. The problem is we take the tests too early. While they’re fairly accurate, the truth is that we don’t really mentally mature until about 22 or so. ANd so it would be more useful if we tested people in order to say, vote, or obtain benefits, or something.

    ANGLOS HAVE LOST PARITY WITH ASHKENAZI SINCE THE INDUSTRIAL REVOLUTION DUE TO DYSGENIC REPRODUCTION: 13.9 IQ POINTS. from 113/114->100, or 1.21 IQ PER DECADE

    https://doi.org/10.1016/j.intell.2014.05.012

    HIGHLIGHTS
    •We respond to a quartet of critical commentaries on Woodley et al. (2013)
    • We show inspection time is not a Jensen effect, unlike simple reaction time
    • We reanalyse data and recover dysgenic trends in simple RT
    • The meta-regression involving just US and UK studies shows a 13.9 IQ point decline
    •Emphasis should be on testing new predictions not purely methodological criticism

    Abstract
    Previously Woodley, te Nijenhuis and Murphy (2013) tested the hypothesis that Victorian era British and American samples exhibited higher g on average than relatively more modern populations sampled from the US, UK, Canada, Australia and Finland, using measures of simple visual reaction time in a meta-analytic study.

    Based on 13 age-matched studies from Western countries conducted between 1884 and 2004 yielding 16 data points we estimated a decline of − 13.35 IQ points. Here we respond to a quartet of critical commentaries on our paper penned by five prominent intelligence researchers (James Flynn, Theodore Nettelbeck, Irwin Silverman, Julia Dodonova and Yuri Dodonov).

    We show via various reanalyses of the data and also via careful consideration of the arguments presented that the original finding of a potential secular decline in simple reaction time performance is robust.

    A recurrent criticism of our finding stems from earlier work showing no secular trends with respect to inspection time over a 20-year period in Australia despite the possibility of co-occurring dysgenic fertility.

    We deal with this via the method of correlated vectors, which reveals the presence of a ‘genetic g’ common factor on which simple RTs, WAIS g loadings and subtest heritabilities load positively and significantly, but on which inspection time does not load.

    This indicates that inspection times are associated with local information processing, unlike simple reaction times, which are associated with global processing (i.e. g).

    The robustness of our original finding is best illustrated however by our final meta-regression, in which the use of six methods variance-controlled reaction time means taken from the US and the UK between 1889 and 1993, coupled with a newly-estimated age-matched reference standard deviation, reveal a seemingly robust secular trend towards slowing reaction time in these two countries, which translates into a potential dysgenics rate of − 1.21 IQ points per decade, or − 13.9 points in total between 1889 and 2004.

    (… ) We thank our critics for helping us to arrive at a much more precise estimate of the decline in general intelligence.

    HIGHLIGHTS
    • Taiwan genotypic intelligence declined by about 1.19 IQ points per generation.
    •The decline is much stronger for the younger adult cohort.
    •Results also show the dysgenic fertility for education and non-cognitive factors.

    Abstract
    This study investigated the current trend of dysgenic fertility in Taiwan. Data on 680 adults aged 35 to 90 years from the Taiwan WAIS-IV norming sample and 980 children aged 2.5 to 7 years from the Taiwan WPPSI-IV norming sample were examined to investigate the relationships between intelligence, education, and fertility. Results revealed that education and intelligence were negatively correlated with fertility, and that the correlations were stronger for females. The genotypic intelligence is estimated to decline by approximately 1.19 IQ points per generation and the decline is much stronger for the younger adult cohort (1.46 IQ points) than for the older adult cohort (1.02 IQ points).

    Evidence of Dysgenic Fertility in China

    https://doi.org/10.1016/j.intell.2016.04.001

    Highlights
    •Evidence of dysgenic fertility in China for both intelligence and educational attainment was found.
    •The strength of recent selection against intelligence rose between the 1960s and the mid-1980s.
    •The estimated decline owing to dysgenic fertility came out to .31 points per decade between 1986 and 2000.

    Abstract
    The relationship between fertility, intelligence, and education was examined in China using a large sample sourced from the population-representative China Family Panel Studies (CFPS) dataset. For the 1951–1970 birth cohort, the correlation between fertility and gf was −.10. The strength of recent selection against gf in China substantially increased between the 1960s and the mid-1980s. Later (between 1986 and 2000), the speed of decline in gf due to selection stabilized at about .31 points per decade with a slightly downward trend. The total loss from 1971 to 2000 due to dysgenic fertility is estimated to be .75 points. A negative relationship between educational attainment and fertility was additionally found. Both negative relations were stronger for women.

    The negative Flynn Effect: A systematic literature review

    doi.org/10.1016/j.intell.2016.10.002Get rights and content

    Highlights
    •We conducted a systematic literature review of the negative Flynn effect.
    •A negative Flynn effect was reported in 9 studies (comprising 7 countries).
    •Immigration, sex ratio, and dysgenic fertility were discussed as possible causes.
    •Findings on IQ decline are discussed in light of the literature on IQ increase.

    Abstract
    The Flynn Effect (rising performance on intelligence tests in the general population over time) is now an established phenomenon in many developed and less developed countries. Recently, evidence has begun to amass that the Flynn Effect has gone into reverse; the so-called ‘Negative Flynn Effect.’

    In this study, we present a systematic literature review, conducted in order to discover in precisely how many countries this reverse phenomenon has been uncovered. Using strict criteria regarding quality of the sample and the study, we found nine studies reporting negative Flynn Effects in seven countries. We also discuss several possible explanations for the negative Flynn Effect as an attempt to understand its most probable causes.

    A two-parent family is a known factor in producing positive outcomes in society. Therefore, these percentages, which continue to increase, are discouraging.

    Percentage of births in the US to unwed mothers:

    Blacks, 77%
    Hispanic immigrants, 49%
    Whites, 30%
    Asians, 27%.

    (You’ll notice that the figure for Asian immigrants is much lower than for Asians overall.)
