I imagine this is the sort of moronic pablum that one can expect from Dennis Prager’s “university.”
There is, of course, no such thing as common sense. It is nothing more than a vague label used to cover all the things one expects to be true for no apparent reason. And many, perhaps most, of the things that people justify as true by referring to “common sense” are, in fact, entirely wrong.
Ever since I attended college, I have been convinced that either “studies” confirm what common sense suggests or that they are mistaken.
