I am seeing more and more people with unusual behavior, that is assertive and irrational in areas outside of there (professional) specialties but lacking any connection to basic facts or methodology.....acting like they were confering with there multiple nobel lauriet buddy, and they "gotcha!", with long reams of blithering psuedo disertational rant. the danger here is that these people are maintaining basic functionality, but are no longer rational, "funtionaly dilusional" if you will
