Foolacy vs. Fallacy

This is the Bandwagon fallacy (argumentum ad populum).

Some peer pressure is Herd Mentality. It’s not usually stated as flawed logic, but it is implied (you should do it because others do).

Also this is common in bad journalism as “people say...” to imply a large herd of popular opinion, whether one exists or not.

While most adults have heard of “bandwagon”, they don’t know why it’s called that, and it has no intuitive meaning to young people. (FYI, politicians used to give speeches standing on a type of horse-drawn wagon that was used to pull bands in parades; followers would hop on to show their support. None of that happens anymore.) “Herd Mentality” is a common expression used these days, with an appropriate negative connotation to point out the fallacy.
