Common sense can have different definitions. But how to increase it?

Can't believe you believe what you wrote

First think for yourself and stop reading self-help and watching 'entrepreneurs' on YouTube

Then get a life

You believe what you believe. But I've made bad decisions which could have been prevented by common sense. I see people displaying non-common-sense behaviors. I observe similar things in myself but when I stop and think about it a little bit more I tend to decrease those behaviors. The 2 tools above have been useful.

Not to mention I've been digging into mental models for many years: https://mmpractices.com/
