Hmm, funny, because a little googling on that gene turned up this:
https://en.wikipedia.org/wiki/Dopamine_receptor_D4 https://en.wikipedia.org/wiki/Dopamine_receptor_D4
Despite early findings of an association between the DRD4 48bp VNTR and novelty seeking (a normal characteristic of exploratory and excitable people),[24][25] a 2008 meta-analysis compared 36 published studies of novelty seeking and the polymorphism and found no effect.
and goes on to say:
Novelty-seeking behavior is probably mediated by several genes, and the variance attributable to DRD4 by itself is not particularly large.
All that does is prove my point. If novelty-seeking, which let's all assume is a proxy for extraversion for the moment, is mediated by multiple genes, then of course there will be a spectrum of variation depending on the combination a particular person possesses.
Care to try cherrypicking again? :)
- lj3 9y agoYou picked the first thing you could find in wikipedia and claim that refutes an article you haven't bothered to read? Who's cherry picking again? Introversion/Extroversion has nothing to do with novelty seeking. Read the article I linked.
- zzalpha 9y agoSure, but the argumentation in that blog post is that novelty seeking is a proxy for dopamine sensitivity, and dopamine sensitivity may be linked to extraverted/introverted tendencies, hence why that gene study is relevant. But, as I noted, since multiple genes likely regulate for dopamine sensitivity (not to mention things like sleep, diet, etc), there are many factors which regulate those tendencies, and it's false to claim there's a dichotomy and that people are fixed to one tendency or the other.
