`Estimates of the total heritability of human traits assume the absence of epistasis, which has been called the "assumption of additivity". Although some researchers have cited such estimates in support of the existence of "missing heritability" unaccounted for by known genetic loci, the assumption of additivity may render these estimates invalid.[12] There is also some empirical evidence that the additivity assumption is frequently violated in behavior genetic studies of adolescent intelligence and academic achievement.[13]`
there are genetic bottlenecks
where a few families end up making the whole population
babygottbach i dont really understand what you are ultimately arguing
you dramatically change the gene pool that way
@BabygottBach why is the assumption of additivity necessary?
are you trying to tell us that children dont inherit genes from their parents?
I don't know, @Nerthulas
that's a simple way groups will difer by time
there
discussion over
I don't understand the statistical measures of heritability to understand why
can you explain why twins perform similarly in different environments if heritability of IQ is bullshit?
He's calling things into question unjustifiably
Some funky sociological mechanism
That quote he just posted is shit
I'm fully justified
It's not even making a counter claim
how is it not?
God of the gaps except god is society
Sure
Where's the counter claim and evidence to back it up
I don't understand, what do you mean some funky sociological mechanism - they have identical genomes
There literally are sociological studies though
the findings are consistent
Post up the study invalidating additivity
>sociology
LOL
why do the twins have similar results?
All you have is variance, @Nerthulas
Exactly
@Nerthulas it conflicts with his world view so he has to invent some random "sociological mechanism" he cant explain
Sociology is literal Frankfurt School shit
```One of the most interesting developmental findings about intelligence is that its heritability as estimated in twin studies increases dramatically from infancy (20%) to childhood (40%) to adulthood (60%), while age-to-age genetic correlations are consistently high43,44. What could account for this increasing heritability despite unchanging age-to-age genetic correlations? Twin studies suggest that genetic effects are amplified through gene–environment correlation as time goes by45. That is, the same large set of DNA variants affects intelligence from childhood to adulthood, resulting in high age-to-age genetic correlations, but these DNA variants increasingly have an impact on intelligence as individuals select environments correlated with their genetic propensities, leading to greater heritability of intelligence.
Developmental hypotheses about high age-to-age genetic correlations and increasing heritability can be tested more rigorously and can be extended using GPS. Does the variance explained by GPS for intelligence increase from childhood to adolescence to adulthood? Are the correlations between GPS at these ages consistently high?```
They have identified many intelligence involved genes
Additivity is correlating with performance
if the twins have similar results in different environments, and that's broadly consistent across studies, then it must be heritable @BabygottBach
what else could be happening?
