I enjoyed imaging the abstract being read aloud by Elizabeth Holmes with her clownish deep voice she worked to portray in the later stages of her fraudulent career. It's funny how these perceptions and findings sometimes line up.
But I agree with you. I've always "dressed up" in work situations, for example, because people respond more positively to me when I look sharp.
I think it witheringly stupid that people would assess my competence based on something so tangential, but if they are going to have a prejudice, why shouldn't I make it a prejudice in my favor (by dressing well instead of whatever I want to wear)?
Short men should be wearing hidden heel shoes, too. Those inches are worth a lot more money than the shoes are. Etc.
