Humans are chimpanzees reciting Shakespeare – dunces with the technology of geniuses. - Steve Stewart-Williams

Most women do not want a career in STEM and nor do most men. Why should the small fraction of women who do want such a career be the same size as the small fraction of men? To put it another way, as long as everyone has the opportunity to pursue a STEM career, and as long as the selection process is fair, why would it be important to get as many women as men into jobs that fewer women want?

Most effects in psychology are relatively unimportant. That is, most variables, considered in isolation, have relatively little impact on behavior. This doesn't mean... that we should all abandon psychology and become plumbers instead. The small magnitude of most effects in psychology is itself a discovery of psychology. One might argue, in fact, that it is one of the great metadiscoveries of the field. Most variables have little impact, and thus most of the phenomena studied by psychologists are products of a multiplicity of variables.

Some may find these conclusions frightening, and perhaps that's an appropriate reaction. But then again, maybe it’s not. For it is certainly possible to frame an ethic consistent with the Darwinian view of the world. Such an ethic might emphasize the virtue of being honest enough and courageous enough to acknowledge unflinchingly that there is probably no God, no afterlife, and no soul; that there is no objective basis to morality or higher purpose behind our suffering; that we are insignificant in a vast and impersonal cosmos; that existence is ultimately without purpose or meaning; and that the effects of our actions will ultimately fade away without trace. It is admirable to acknowledge these uncongenial truths, yet to struggle on as if life were meaningful and strive to make the world a better place anyway, without promise of eternal reward or hope of ultimate victory, and indeed for no good reason at all.
