It depends on context, and I think most people realize this intuitively. If you put pumpkin in somebody’s berry smoothie they’re going to be pissed no matter what the scientific community says lol. It’s the kind of thing that only matters for trivia.

And honestly science appropriated the term from common parlance, not the other way around. So a layperson could just as easily walk into a botany lab and say “fun fact, these actually are berries” and be completely correct.
