You have it backward, JW.
The extrovert has a driving need to fit in and conform - a social sycophant with a need to actively demonstrate membership of a group.
As far as as introverts are concerned, safety derived from hiding within and submitting to a group mindset counts for little and conformity, as a consequence, isn't a priority.
I know (at my airline) where all the successful union leadership over the last several decades came from and I know the background of those who didn't have the moral character or backbone to stand against that which was commercially expedient but detrimental to safety.
