The ENTP with whom I work seems to always be sucking up to authority figures. He seems to be forever carrying news and gossiping about others with the authority figures and with subordinates and colleagues on an equal level he seems to be always either indirectly threatening to report some minor and I mean really thing they did to someone more senior. I am an INFJ who have no particular respect for authority; I thought that ENTPs were likely to be a bit anti-authority too only to find that not even the ISFJs I know seem to be sycophantic and obsequious with authority. What is going on here? Is this some kind of shadow ENTP behavior linked to fourth function Si?
