Is UCSD's environment competitive?

I’m looking into majoring in Cognitive Science, hopefully at UCSD. I’ve heard that UCSD’s environment and feel is very competitive, and a bit dead (social-wise). Is this true? I want to be able to make friends easily and learn in a healthy environment.

Since I’ve been here I haven’t had any issues with competitive

people and everyone has been pretty chill so far. I am in Warren tho and it is kinda socially dead but on the other side of campus near muir seventh and sixth there’s a lot more going on
