Of course there are genetic influences and not everybody can be an Einstein or rocket scientist. But below that level there is a lot possible that has nothing to do with genetics. Most things are more influenced by motivation than the ability. And on that the real cause does not matter.

If the people would spend only a fraction of the energy, they waste with questioning if something is genetic or not, in the development of skills by learning - they would improve beyond the proclaimed "genetic" level.

Reduce media consume. Reduce politics. Almost the whole discussion is toxic. The right proclaims everything is genetic but on the other side punish people not having the "good genetics".
