Ad Populum 

When people claim something is automatically right because a large number of people are saying it. You can have a scenario with a hundred idiots and all their mates vs 1 clever person on their own. The karma system on reddit is probably the most egregious implementation of this idea tbh since people blindly assume upvotes = 100% correct in all scenarios

Person A: that game has bad reviews so it must suck. All my mates said it suck so it must be true

Person B: have you played it yourself? Sounds like Ad Populum to me
Person A: huh?

Ad Populum Fallacy 

Tucker is also using ad pop as his justification believing that God created humans and that there is a spiritual battle between good and evil.

Tucker "EvErYoNe BeLiEvEd It! Everyone has ALWAYS believed it! Dattebayo!"

Hym "Heheheheheh Dattebayo... No, hey, that's the 'Ad Populum Fallacy.' A large number of people believing something (even historically) is not evidence for the truth of the claim."

dissensio ad populum

The notion that something is wrong when the majority disagrees. This contrasts with "argumentum ad populum," or the false notion that something is true when the majority agrees.

Person A: The Earth is flat.
Person B: The Earth is round; dissensio ad populum.
