We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
The most important finding in psychology in the last 50 to 100 years, I would say, is the finding that everything you can measure is heritable. The heritability coefficients vary between 0.3 and 0.6, or 30 to 60 percent of the variance, under some assumptions, can be explained by the genes. It’s the largest piece of variance we can explain.
People assume the nongenetic component is environmental. Some of it is, but it also includes the error term (always large in biology) and any mutations or copying errors that occurred. The reported heretibility is usually a minimum estimate.
I was hastening to say the same as Mr. Sykes. We are not to include that the rest is environment.
This is national social work month, and today's speaker was giving the ritual speech about how import intervention is, because that's what we do. He listed ten types of trauma that can have a bad effect on life outsomes, including such things as divorce, physical and sexual abuse, etc. He stated that as few as three of them can work additively to devastate life outcomes in terms of shortened life, drug addiction, incarceration or similar bad happenings.
Well certainly, those aren't good for you. But genetic influences were not only not listed, it was clear from his speech that they weren't thought of. That the parent who physically abuses you or abandoned the family also gave you half your genetic material does not even process for such folks. Such are their assumptions, such is their training, such is what sustains them to go out and try another day.
Environment does have effect, as people respond to incentives and over time those might become habits. But that's about it.

Uh, "conclude." Sorry.
