The thing is it’s likely an evolutionary adaptation of being overturned for… something. I suspect hunting. Hearing a twig crack, being hyper focused and not being able to get something out of your head. Tracking your prey for hours, these would be useful in a low stimulation environment like say, the woods of Europe 20,000 years ago. It’s certainly a deficiency in most modern humans as we aren’t out chasing down prey, but that doesn’t mean it was never a useful trait.
