I think things are a bit different in the age of the internet. Seeing into the private lives of others, their quirks and eccentricities, you might find that these traits are fairly common, and even desirable by certain sociocultural groups to be as 'odd' and 'quirky' as possible, as it seems to correlate with success and the capacity to think differently.

Self confidence, I agree is huge, but it can't be faked. It has to actually be known. Sometimes that seems to mean letting your mind go for a loop, coming back again, and realizing you can never know anything while also knowing something.

I just don't really think any of the side effects of being a percieved genius matter as much as the work actually done. Sometimes it means going against the crowd, sometimes it means going with.
