don't those twin studies, where they reunite twins adopted out separately
show some spooky flavor and scent related choices? iirc, they often show
up for the study with the same brand of toothpaste, aftershave, etc.

fwiw, a brief web-surf yielded:

"Yet despite the stark contrast of their lives, when the twins were
reunited in their fifth decade they had similar speech and thought
patterns, similar gaits, a taste for spicy foods and common peculiarities
such as flushing the toilet before they used it."
