Marshmallow Test Fails to Replicate

I'm not making up that lipstick is heritable; it is a classic example of a non-genetically-determined heritable trait, as is hand count (in the other direction). I think you need to do some more reading: you are clearly using the term as a synonym for "genetically determined", and that is simply not what the heritability statistic tells you.

For what it's worth, you can mechanistically work out lipstick and hands from first principles; just plug rough numbers into the formula.

When you say things like lipstick wearing is a classic example of a non-genetic heritable trait, you sound like a guy claiming that a cat is a classic example of a non-reptilian reptile. It's a completely nonsensical word salad.

"Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population."

You are using the term in a colloquial or folk sense. Do you think accents are highly heritable? After all, a child will almost always share the accent of their parent. So in the colloquial sense this would be a 'heritable' trait, but in the genetic sense the heritability of an accent is zero.
