Does your theory apply to *only* personality traits or to all genetic traits? I'd have to say I think some examples may fall outside your theory. On the physical side, some people exhibit conditions at a later date in life that, as far as we can tell, are not always environmentally induced: take adult diabetes for example (environmentally induced sometimes, but not others). On the psychological side I think schizophrenia would be an example - in some people it simply develops out of nowhere, genetically predisposed, IIRC.

I admit I'm not an expert on genetics and so on. And it's not 'my' theory
. However for the schizoprenia example, the theory covers that I think. When you say it's genetically predisposed, that's true (for some) but genes don't just express themselves - they can't. A lot of the stuff people think about genes is based on bacteria - gene expression is different for bacteria, the genes know how and when to express themselves without any signal. Human genes don't, they sit about in their double helix (lol
) and wait for a signal to tell them when to express themselves. So yes many disorders do have a genetic component, there's a lot of evidence of that from twin studies and so on (but again, not concrete 100% evidence, for example something like bipolar disorder has one of the highest genetic influence of psyhological disorders, but even that is only about 70%), but the genes have to express themselves from something. How do you *know* it develops out of nowhere? You can't possibly.
