The psychologist said this research has several interesting implications. “For starters, schemas serve many useful functions. But, when schemas are broken, they increase learning. So, presumably, people need to overcome their natural tendency to protect their schemas to maximize their ability to learn.”
In practical terms, this could suggest that when people isolate themselves from outside information to protect their schemas (such as only watching or reading things that verify their views), they hinder not only their ability to learn about other perspectives (through a lack of information) but also their ability to learn anything novel or different.
So when you think about it, the folks behind these signs are actually doing a public service. They’re increasing everyone’s desire and ability to learn. I know, it sounds like a stretch, but science says so!
