Bandwagon Fallacy

A Bandwagon Fallacy is when a statement is assumed to be logically valid because of popular support.

Bandwagon Fallacy Examples

Bandwagon Fallacy Example 1

“Does god exist? Several billion people can’t be wrong!”

Yes they can, in fact 100% of humanity could be wrong, there was a time when no one understood disease thinking it to be evil spirits. The number of humans believing in a thing has no bearing on reality. Do I know if a god exists? No and neither does anyone else and it doesn’t matter if 99% of humanity believed we should still require evidence.

Bandwagon Fallacy Example 2

“7 in 10 doctors say acupuncture works, therefore it must work”

Here is a combination of appeal to authority and the bandwagon fallacy. Many people place trust in an authority on health like a doctor so when a majority of them promote a thing it must be true! No, sorry again, but this just isn’t so. We always need evidence, easily obtainable, repeatable, and testable evidence.

Bandwagon Fallacy Example 3

Many people once thought the earth was flat, this certainly didn’t make it so.

Logic Structure of Bandwagon Fallacy

Premise: Many people believe A to be true

Conclusion: Therefore A is true

Bandwagon Fallacy For Religious People

I would like to convince religious people not to use arguments of popularity. I will use variable religions in my next examples to show why religious people would not want to adopt fallacy of the majority structures into their belief systems.

  • When Moses (if he existed) first taught Torah no one else was Jewish
  • When Yeshua (if he existed) first taught gospel no one was Christian
  • When Muhammad (if he existed) taught Islam no one was Muslim

Using the above examples, these religions would have automatically been false if arguments of popularity were in fact valid structures by which to support claims. If you are religious you have to dispense all notions of popularity or belief founded on sheer number of adherents. This also means that forever and into your future you should never take into account if your friends and family are of a certain religion, for this is reasoning by an Bandwagon Fallacy.
