It's not just cognitive. We lose taste buds with age, and the ones that remain shrink and lose sensitivity.
It makes sense if you think about it. Bitterness is associated with a lot of poisons. Sourness is associated with spoiled foods. Having a strong aversion to these tastes during childhood compelled our ancestors to avoid dangerous foods during their most fragile stages of life.
Then of course, sugar is a quick source of energy. It should be a given why a quick source of energy benefitted our ancient ancestors (for whom food was much more scarce.)
In short, that increased childhood sensitivity allowed our ancestors to survive until adulthood.
So parents - next time a kid complains about their dinner being too bitter, take comfort in knowing that if they were ever exposed to actual poison, they'd avoid it with the same urgency.
While I agree with you on some of the above, I disagree with your choice to insult both the artist (“insufferable”) and the art (“moronic.”) It really weakens your point when you throw ad hominems into your argument. Your valid criticisms become clouded by an apparent bias, leading people to take your point less seriously.
