> Smile to Feel Better Effect

> Claimed result: Holding a pen in your teeth (forcing a smile-like expression) makes you rate cartoons as funnier compared to holding a pen with your lips (preventing smiling). More broadly, facial expressions can influence emotional experiences: "fake it till you make it."

I read this about a decade ago, and started, when going into a situation where I wanted to have a natural smile, grimacing maniacally like I had a pencil in my teeth. The thing is, it's just so silly, it always makes me laugh at myself, at which point I have a genuine smile. I always doubted whether the claimed connection was real, but it's been a useful tool anyway.

Yeah, the marshmallow one taught me to have patience and look for the long returns on investments of personal effort.

I think there may be something to a few of these, and more may need considering regarding how these are conducted.

Let’s leave open our credulities for the inquest of time.
