Flam is a small village in Norway. Tourists who take the Norway in a Nutshell tours switch ferry boats here. A cozy restaurant called Bakkastova Cafe is located up on the hill.

This restaurant had a note at the cash register. It says, statistics say that women are tipping better than men. I added coins to the tip jar labeled men because I wanted to oppose this questionable argument. Others might tip if they support it.

This suggests that scientifically proven or well supported arguments may fail to motivate people to behave in a certain way. Rather, incomplete, controversial arguments trigger people’s willingness to speak out and may lead them to make an action. From the behavioral economics’ perspective, people’s avoidance for perfection seems to be a better nudge compared to either putting on some lipsticks to make something look like a human or painting foot prints on the street.
