IQ

[Woodchopper]

I remember Sheldrake posthing this

How much is a child’s future success determined by innate intelligence? Economist James Heckman says it’s not what people think. He likes to ask educated non-scientists — especially politicians and policy makers — how much of the difference between people’s incomes can be tied to IQ. Most guess around 25 percent, even 50 percent, he says. But the data suggest a much smaller influence: about 1 or 2 percent.

As discussed with Sheldrake, that is the effect of intelligence alone. Income appears to be a the result of an interaction between several factors - eg intelligence, education, aspects of character like perseverance, and home and neighborhood environment.

And inheriting a few million from yer parents.

I'd include that in with the home environment.
