International bestselling authors all have IQs 140 and above. You can’t have that sort of IQ without a math brain. Nothing to do with training. I’ve noted from various throwaway comments that the really good writers on Medium are also gifted, i.e. they have a math brain.

Not something you are taught. You are born with it.

One can certainly earn the scientific method — not much to it. One has to check for evidence before one draws a conclusion. However, how good one is will depend on how good one’s math brain is.

Good artists also have math brains. The best computer programmers are musicians.

And, sorry if I’m condescending. I don’t mean to be.
