If so, elaborate on that. If not, please explain why those same things should not be considered problems that ought to be addressed. Wouldn't it be advisable to treat the issue like any other and apply the full weight of your intelligence and experience to come up with a good solution?
I don't deny that any of the above traits can be barriers to success. The underlying problem I see requiring attention is different, though, than the problem you and thras suggest we need to solve. When someone encounters barriers due to their appearance and/or image, the best solution I see does not always involve individual behavioral modification. I also go looking for systemic causes. In this case, I think there is a halo effect that is not being addressed and compensated for, or is being assumed as static and unmovable. It results in people being judged on things that do matter to the end product based on things that do not matter. A Porsche is not a faster car than a Honda because the engineers dressed nicer to the factory, nor the opposite; it is tangential. This halo effect is the thing we need to be addressing, rather than attempting to rely on patching ourselves due to errors in the system. I hope my point is a little clearer now.
