I think with topics where one isn’t an expert it can be more important to know what “most people” in your social circle *think* is true than it can be to know what is really true.
Knowing an iconoclastic truth, but not having the expertise to explain it to others isn’t very useful. Moreover without that expertise you will struggle to evaluate the validity of the unpopular opinion.
So, people reach for the popular option and hope it is correct.
