There is some evidence that <i>suggest</i> that (with a very important caveat that I will soon note) liberals have higher sex drives, as seen by <a href="http://bigthink.com/e-pur-si-muove/why-are-liberals-twice-as-likely-to-cheat-as-conservatives" rel="nofollow">Satoshi Kanazawa's finding that liberals are more likely to be unfaithful</a> and <a href="http://jaymans.wordpress.com/2012/11/08/some-guys-get-all-the-babes-not-exactly/" rel="nofollow">my own finding that the men with the most children have report the fewest number of sex partners</a>.<br /><br />The caveat of course is that both data sets are based on self-report and are likely be wrong because the respondents were lying (conservatives may be less willing to admit to having sexual affairs or to admit the true number of sexual partners they've had).<br /><br />In any case, if this is accurate, greater conservative reproduction, at the high-IQ levels especially, may not be clearly related to life history speed.JayManhttp://jaymans.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-4683970826895755480.post-53230062248589510852013-02-28T05:55:03.163+00:002013-02-28T05:55:03.163+00:00@Thu - the way I have expressed it is that above r...@Thu - the way I have expressed it is that above replacement fertility is *chosen* (only) among those of orthodoxly traditional religiousness. <br /><br />And I regard this as one of the strongest of arguments against atheism (and 'liberal' religions).<br /><br />To be self-identified in 'liberal' (etc) is not precisely *incompatible* with holding the kind of religious convictions (leading the kind of religious life) that correspond with chosen above-replacement fertility - but it is unusual (and based on inconsistency of conviction when it is reported - but of course many religious conservatives *vote* for extreme liberal government because Leftism bribes them with privileges and subsidies - certainly not because they approve of the Leftist agenda as such)Bruce Charltonhttps://www.blogger.com/profile/09615189090601688535noreply@blogger.comtag:blogger.com,1999:blog-4683970826895755480.post-13627654573100180282013-02-28T05:04:46.713+00:002013-02-28T05:04:46.713+00:00I now have data:

At the individual level, within a population, i...2. At the <b>individual</b> level, within a population, intelligence and life history speed are uncorrelated.<br />-<br />Surprising, if true. How do we know it is true?<br /><br />The reason I say "surprising" is that now in the multicultural West we are looking at actual "populations" formed by the forced association of radically different natural populations.<br /><br />In, say, medieval England, the non-association of intelligence and life history speed would be less surprising, though the claim that there was no association would still call for evidence.<br /><br />But imagine a population now. Half its members are of genetic type W, with an average IQ of 100, a slow life history speed, and an inherited temperament that includes a tendency to create culture congenial for that sort of person. Half the members of this population of forced association are of genetic type B, a full standard deviation less intelligent, and built for speed in temperament, in the sort of culture that they make, and in physical rates of maturation. They are a year to two years faster to puberty and so on.<br /><br />The two sub-groups of this population are different kinds of animals stalled together, with different genes, bones and brains, and consequently different typical cultures, polities, economies and so on.<br /><br />Why would you expect that in this artificial population of forced association there would be zero correlation between intelligence and life history speed?Daybreakernoreply@blogger.com
