but that depends on how large the factor actually is. if it were 10% or more, then sure. but the fact that the very existence of a genetic factor is put into question, suggests that the factor, if it exists, is so small that it really is negligible.

another reason why we can ignore a genetic factor is that we can not influence it. or, that trying to influence it carries serious ethical implications.

it is also to small to serve as a tool to predict future performance.

The existence of a genetic component is put into question by some, but by no means all.
