If the traits that produce a person of high "merit" are 50% due to genetics and another 25% to environment from conception to age 3 (as most studies suggest), how to you plan on solving the "root cause" of the problem? In the US at least, people a more and more mating with their peers in IQ, conscientiousness, and culture. With the huge variation in human traits, a meritocracy is going to see massive inequality especially over generations. Careful what you wish for.
- konceptz 9y agoDo you have a source for these statistics? You put merit in quotes and then stated percentages plus the claim that there is a growth in similar IQ partnering.
- iguy 9y ago50% genetic + 50% "unshared environment" is the rule of thumb for any complex trait, I assume that's what GP had in mind. Unshared env is a polite way of saying noise; approximately 0% "shared env" i.e. parenting, education, etc. (There are many caveats, obviously.) You could do worse than https://en.wikipedia.org/wiki/Heritability_of_IQ#Estimates https://en.wikipedia.org/wiki/Heritability_of_IQ#Estimates as a place to start.
- frockington 9y agoCompound your statement with education level being inversely related to child bearing and you're looking at a society with one small educated elite and one large "general" population starting to form in the next few generations. I am nervous that we will soon blame genetics for inequality and take rash actions.
