Here’s a gem from the interview:
If people are in a good mood on a given day, they’re more likely to have creative ideas that day, as well as the next day, even if we take into account their mood that next day.
There seems to be a cognitive process that gets set up when people are feeling good that leads to more flexible, fluent, and original thinking, and there’s actually a carryover, an incubation effect, to the next day.
So happy people really are more creative. I knew it!
