I am looking for a word that means “tendency to avoid something”. At first I thought that aversion fit the bill, but then I learned that it meant “a strong dislike towards something.”
For example, most people have an aversion towards feces. I am looking for a word that more along the lines of “they don’t hate PBJs, they just try to avoid them as much as possible.”
disinclination might fit. It covers both unwillingness and a mild aversion so you tend to avoid that thing. It does not suggest a strong dislike also.
a lack of inclination; a mild aversion or reluctance.
that toward which you are inclined to feel dislike
