I disagree with the last paragraph. If there are four factors that all combine to create an outcome, we don’t ignore factor 1 just because factors 2-4 can nullify any advantage.

My garden grows based on light, CO2, macro nutrients, and water. We don’t say “CO2 is not a factor in plant growth because deficits in water, nutrients, and light can prevent it from showing in overall outcome.”

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.
