Imposter Fallacy

Description: When one suggests or claims, with insufficient evidence, that the group outliers who are viewed as damaging to the group are primarily made up of infiltrators of another group with the purpose of making the infiltrated group look bad.

This is similar to the nutpicking fallacy in that the group outliers and the “nuts” are equally as embarrassing or damaging to the group, but with the imposter fallacy, the outliers are claimed to be actors or imposters. This is also similar to the no true Scotsman fallacy in that a foundational claim is that no “true” group member would act in this way, so they must be an imposter.

Logical Form:

Group A comprises members X,Y, and Z who act in a way that damages group A’s reputation.
Person 1 suggests or claims, with insufficient evidence, that members X,Y, and Z are actually part of Group B who are there to make Group A look bad.

Example #1:

Frieda Freestuff: I can’t believe you support Trump. Didn’t you see the Trump rally with the group of supporters holding up signs for “White Power?” Do you really want to be associated with that message?
Garry Godznguns: Those aren’t Trump supporters; they are liberals pretending to be Trump supporters just to make Trump supporters look bad.
Frieda Freestuff: It’s working.

Explanation: There is no question that imposters exist. It is not uncommon that political rivals will pretend to be the worst of the other group with the goal of damaging the other group’s reputation. The problem here is that Garry Godznguns has no evidence to back up his claim, and there is plenty of evidence to the contrary that white supremacists and white nationalists overwhelmingly support Trump.

Example #2:

Peter Procops: I can’t believe you support these protests. People are being injured and killed. Property is being destroyed. Stores are being looted. Our city looks like a war zone!
Patricia Defunddapopo: The protesters are peaceful and lawful. It was just on the news that a guy they arrested for vandalism was a white nationalist who admitted vandalizing to make the protesters look bad.
Peter Procops: It’s working.

Explanation: While it is true that the guy arrested was a white nationalist who admitted vandalizing to make the protesters look bad, this was one case out of thousands. There is video documentation of known activists advocating for looting, vandalism, and even arson. The evidence strongly suggests the majority of destruction is not due to the imposters.

Exception: This is a fallacy contingent upon evidence. If enough evidence exists that the majority of the group outliers in question are imposters, then there is no fallacy.

Fun Fact: The imposter fallacy is often committed with the deceptive sharing fallacy when one shares a one-off story about an actual imposter.

This is an original logical fallacy named by the author.

Eat Meat... Or Don't.

Roughly 95% of Americans don’t appear to have an ethical problem with animals being killed for food, yet all of us would have a serious problem with humans being killed for food. What does an animal lack that a human has that justifies killing the animal for food but not the human?

As you start to list properties that the animal lacks to justify eating them, you begin to realize that some humans also lack those properties, yet we don’t eat those humans. Is this logical proof that killing and eating animals for food is immoral? Don’t put away your steak knife just yet.

In Eat Meat… Or Don’t, we examine the moral arguments for and against eating meat with both philosophical and scientific rigor. This book is not about pushing some ideological agenda; it’s ultimately a book about critical thinking.
