I'm pretty sure that in her zeal to encourage people to keep learning and growing, she's stretching the truth by assigning intent where there may be none and exaggerating small samples to big populations (where exactly are all these people she repeatedly refers to who do nothing else but sit around saying/proving how smart they are? In my 20+ years in business plus time spent at a top-tier business school, I can only recall a small handful I'd describe as remotely like that, and in those cases, I would ascribe it to them just being jerks.)
