I think part of the problem is that Holmes's voice sounded artificial. To be effective, generally speaking, you would imagine the voice couldn't sound like you were trying to speak with a deep voice. (But surely studies have been done on this. Does it matter?)

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.
