A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

Facial expressions are a powerful form of communication. Faces (especially eyes) are so important to communication in the human brain that we see faces in places (pareidolia).
There is also a theory that we evolved to have the whites of our eyes visible so others can see where you're looking and react appropriately (especially in the case of danger).
Do you have any sources on that?
I'm not trying to call you out, I'm interested in reading more.
Sure. It's called the Cooperative Eye Hypothesis.

Some researchers have called it into question fairly recently: https://phys.org/news/2021-06-cooperative-eye-hypothesis.html
I learned most of this in psychology classes years ago. There is also a Wikipedia article on the topic. I'm not an expert at all, but I find this stuff fascinating.
