I've encountered a number of studies using randomly put together groups which are rewarded based on performance of some task - organically select a leader based on display of confidence, rather than competence. I reason that it is not uncommon to assume competence from an extroverted person. I can't really argue with that, it's a fact, use whatever card you got dealt to get ahead. I am just bemoaning the fact that slowly but surely the field becomes skewed towards that, losing a good amount of original core values in the process. Hasn't something similar already happened to academia for example?
