    Tldr: everything you thought you knew about what makes people into criminals is probably wrong.https://twitter.com/TaniaArline/status/1003060146396848128 …

    Among 2,267 sibling pairs, genetic influences accounted for 97% of the stability in criminal behavior from adolescence to adulthood (13 yr time span). Shared environment accounted for 0% of variance in stability and change in criminal behavior. https://www.researchgate.net/publication/256919824_On_the_relationship_of_past_to_future_involvement_in_crime_and_delinquency_A_behavior_genetic_analysis … @FSNole57

        Culture doesn't explain much variation within cultures.

        Yes, consistency over time, like from one age to a later age.

        i would expect a significant, even majority genetic component but that sounds... suspiciously high?

        Important to note that non-shared environment explains majority of the variance in behavior change

        (re: @ESYudkowsky too) Sadly, I have some personal experience in this & would like to add: there is no "same environment" for any two siblings. A year of age difference can be huge in terms of how family acts toward child, but parents even treat twins differently. No excuse, ofc.

        What if this was everything I thought about criminal behavior?

        Stability want that high so that number isn't that informative. The fact they found zero shared environmental effects on wave 1 surprises me. Potential that's very significant but I've seen different results in other twin studies of criminality. I suspect sampling issues.

        Don't you mean repeat offenders? Not criminals in the first place.
