Another confirmation of our prime adage ‘never assume.’ James Dean and the young Marlon Brando were the epitome of cool: rebellious, dark, emotionally controlled and thrill-seeking. I and most of the boomer/GenX crowd assumed that this was still the case. So did the author of a study by a Rochester University researcher who set out to confirm that cool was still what it was. He found out that to today’s mainstream GenMs & Ys, ‘cool’ was something completely different. The main thing he found was that now ‘cool’ means ‘I like this person’. This person is nice to people, attractive, confident and successful. Note to managers: be cool.
