How BS spreads, a case study:
-@JamesLingford cites Devlin et al as showing that the heritability of IQ is less than 60%
- Fails to note that this analysis is heavily based on children and the heritability of IQ increases with age...

- Devlin et al claim pre-natal influences bias twin studies of IQ
-Lingford neglects to mention that this has since been falsified by researching showing that similarity in the MZ pre-natal environment doesn't increase similarity in IQ...

-Kevin Bird shows up to cite old research with an inferior sample size as showing that there is a pre-natal bias that explained 14% and 10% of the variance in IQ similar to the estimates of Devlin

- the paper attributed only 1% of the variance in total IQ to pre-natal effect with a CI that included 0% and that the heritability of IQ in this paper was estimated to be over 75%.
This concludes our case study in bullshit.
