That wasn't really common sense in that definition of the term, rather it was thinking of advantages versus disadvantages. I don't think that considering the reality of people outside of your own group is "prejudice", yet it is common sense.

Forget "common sense." Make the argument that something makes "good sense" and support that argument with logical reasoning and evidence.

"It's just common sense" is simply an excuse to stop thinking, be it about the characteristics of the natural world, (which is, I think, what Einstein was getting at), or about human behaviour and characteristics. Things called "common sense" may even make good sense. So think about them and make the relevant case. Things called "common sense" are also often really just plain nonsense when dragged out into the light of proper critical analysis based on solid evidence.

Sure, I already made that argument. Renaming it is only a benefit for a small subset of the global population and only because of their own biases, as such it shouldn't happen.

Common sense is also the good sense that should be expected of the common man.
