Dinosaurs (Intelligence)

ELI5 - Dinosaurs were around for millions of years. Why didn't they become more intelligent?

Smarter doesn't always mean better. It often takes more energy to run a bigger brain. If your current level of smarts works well for your life, having a bigger brain could actually be a problem. Evolution doesn't aim for intelligence as its main goal; there are different ways to survive and reproduce without needing to be super smart.

That said, we know some dinosaurs like parrots and corvids are pretty clever. But does this mean all non-bird dinosaurs were not very smart?
