A lot of people put too much stock in personality tests like the Myers-Briggs, myself included. I'm still curious whether the results could be applicable to social structure.
For instance, NT types are supposedly skilled at theoretical analysis, and SF types are good at dealing with people. Could an organization use NTs to make many of the detailed decisions with broad implications, and the SFs to help maintain internal cohesion?
The psychologists in Human Resources should look into this. It'll do more to maximize your profits than just refusing to hire introverts because reasons.
