linguistic relativism, or the theory that specific languages play a significant role in our general cognition, but outside of some very minor effects, evidence simply doesn’t support it.
Have you seen the movie Arrival? This is where I first learned of this.
I talked to a neurologist friend afterward who was convinced of it, along with his M.D. psychiatrist girlfriend. I’m surprised to hear it’s less certain to linguists than to medicine. Unfortunately I forgot the evidence I found so compelling, maybe it was that I had just seen that movie.
