@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?
It's simply trying to create doubt
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
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?
can you explain?
And you come in with a "maybe this or that" to counter actual positive data
`These are valid concerns – because genetics are rarely accounted for in sociological research on parental, neighborhood, and school influences on children, if genetic factors are related to shared environments and the outcomes, genetic confounding is a possibility. Because sociological and other social science research frequently concludes that these social environments are major determinants of educational prospects in early childhood (Alexander, et al., 2007, Fryer and Levitt, 2006, KewalRamani, et al., 2007), adolescence (Camara and Schmidt, 1999, Hedges and Nowell, 1999, Kobrin, et al., 2007) and beyond (Elman and O'Rand, 2004, Roscigno and Ainsworth-Darnell, 1999), it is important for sociological researchers to critically examine this literature to evaluate its conclusions.`
I don't care about naked theory
@Nerthulas it cant be the case that things could be heritable because that would be racist
