Defined as such, liberalism is evolutionarily novel. Humans (like other species) are evolutionarily designed to be altruistic toward their genetic kin, their friends and allies, and members of their deme (a group of intermarrying individuals) or ethnic group. They are not designed to be altruistic toward an indefinite number of complete strangers whom they are not likely ever to meet or interact with. This is largely because our ancestors lived in a small band of 50-150 genetically related individuals, and large cities and nations with thousands and millions of people are themselves evolutionarily novel.
Conservatives often complain that liberals control the media or the show business or the academia or some other social institutions.
The Hypothesis explains why conservatives are correct in their complaints. Liberals
do control the media, or the show business, or the academia, among other institutions, because, apart from a few areas in life (such as business) where countervailing circumstances may prevail,
liberals control all institutions. They control the institutions because liberals are on average more intelligent than conservatives and thus they are more likely to attain the highest status in any area of (evolutionarily novel) modern life.
Sadly, as the United States seems to continue to “Dumb Down” (I suspect a conservative conspiracy, for conservatives benefit from a stupid population that can be ruled by fear and superstition, thus vote against their best interests) Liberals
do not control the media.
