In this article from Scientific American about smiling, we get challenged on the idea of ‘move your feet and your heart will follow. It seems that the idea that ‘people who smile are in a better mood therefore if you make yourself smile you will be in a better mood’ doesn’t actually work.
And it has to do with the fact that knowing how to ‘game’ the system – use its rules against itself – actually has a detrimental effect. Basically, you’re not as dumb as you think you are. People who know that smiling makes you happier don’t get happier when they smile to do so.
I just find this to be interesting in that markets – fixed income, equity, housing, you name it – are all run by people making decisions related to each other but also trying to ‘game’ the system into paying them more than other participants.
I guess you could say this article says you can fool some of the people some of the time but you can’t fool yourself!
