I don’t really see any reason why you couldn’t just do a setwise comparison and check which of the extraversion increasing variants (or combinations of variants if epistatic effects dominate) increase the trait without increasing conformity to social desirability.
In fact if you just select for disagreeableness as well that might just fix the problem.
The key distinction is that IQ demonstrates a robust common pathway structure—different cognitive tests correlate with each other because they’re all tapping into a genuine underlying cognitive ability. In contrast, personality measures often fail common pathway tests, suggesting that the correlations between different personality indicators might arise from multiple distinct sources rather than a single underlying trait. This makes genetic selection for personality traits fundamentally different from selecting for IQ—not just in terms of optimal selection strength, but in terms of whether we can meaningfully select for the intended trait at all.
There is such a thing as a “general factor of personality”. I’m not sure how you can say that the thing IQ is measuring is real while the general factor of personality isn’t.
Sure big 5 aren’t the end-all be-all of personality but they’re decent and there’s no reason you couldn’t invent a more robust measure for the purpose of selection.
