I confess I did not see that. Still, I don't think one is a precise judge of talent one minute and the next minute (having determined that all other things are equal) switches to filtering for conformity. It's much more likely to be the other way around: first we see through our filters and then we judge what we see. Especially when what we're judging is something intangible like talent.
You claim it is simply conformity? I suppose this is a matter of opinion, and I am not so foolish as to think I can change yours. I will close by simply observing that to me, presenting yourself in a polished fashion is a display of respect, interest, and investment in the matter at hand. Even if it was simply a display of conformity, I disagree with your implicit presumption that conformity is by definition evil. You must pick your battles, and to me, what I wear to an interview is pretty low on the list of priority.
Ah, you've replied while I was busy editing my comment. Usually I get away with that without a collision. Well, I've tried to make it more reasonable and I suspect we don't really disagree that much. But I will add something: there are quite a few talented people who don't really have the choice to conform. They just don't "get" the social system well enough. And yeah, maybe part of it is that they're not interested enough to force themselves to do it. And I like a lot of those people and I don't like it when others turn their noses up at them.
Conformity isn't evil per se, but judging people for lack of it often is.
Interestingly, "conformity" is one of those words that no one uses about themselves. Like "tourist".
