False Equivalence

Description: An argument or claim in which two completely opposing arguments appear to be logically equivalent when in fact they are not. The confusion is often due to one shared characteristic between two or more items of comparison in the argument that is way off in the order of magnitude, oversimplified, or just that important additional factors have been ignored.

Logical Form:

Thing 1 and thing 2 both share characteristic A.

Therefore, things 1 and 2 are equal.

Example #1:

President Petutti ordered a military strike that killed many civilians. He is no different than any other mass murder and he belongs in prison!

Explanation: Both president Petutti and a mass murder share the characteristic that something they did resulted in the death of civilians. However, the circumstances, the level of responsibility, and the intent are significantly different for the president than the typical mass murder and ignoring these factors is unreasonable, thus makes the argument fallacious.

Example #2: Using the second amendment as justification to allow civilians to own nuclear submarines.

Explanation: In this case, the first "thing" is the weapon as understood at the time the second amendment was passed. The second "thing" of comparison is the nuclear submarine, also a weapon, but one of significantly different magnitude. This example also introduces the difference between a legal justification and an argumentative one (see Appeal to the Law).

Exception: Like most fallacies, this is one of degree rather than kind. The order of magnitude can be debated. Some may exaggerate this order of magnitude claiming a fallacy where it would be unreasonable to do so.

This is a logical fallacy frequently used on the Internet. No academic sources could be found.

I have pointed to the violinist argument as a false equivalence, would you agree with that assessment?

Not sure what you mean. Where did you point to this?

@Bo Bennett, PhD: it is a contentious argument, but it is an anecdotal example in “A Defense for Abortion” where the reader is asked to imagine they wake up attached to a world class violinist as a dialysis machine and argues that since you both have bodily autonomy then using a pro-life stance, you shouldn’t have the right to disconnect from them. My assertion was that since a mother isn’t kidnapped and forced to carry a child, this is a false equivalence as it sets up an argument that seems morally identical on the surface, but is two entirely different situations when analyzed with a little more scrutiny. My argument is not for or against either side, just that the example presented in 1971 and pointed to for decades as “common sense” is fallacious and a new argument needs to be presented.

@T Mac: Not sure if this works because the idea of being kidnapped is incidental to the argument. The analogy works because in both cases consent is not given. And the mother is being forced to carry a child, which is the reason the argument is needed.

@Bo Bennett, PhD: I believe the idea of being “forced to carry” is a straw man fallacy of sorts in that the pro life argument doesn’t argue to force the mother to carry the child, it is incidental to not allowing her to terminate the perceived life, which to one with a pro life stance is seen as murder. Also, I feel being kidnapped is not incidental but essential to the argument presented especially given that there are dialysis machines that would work to save the violinist’s life so the kidnapping and forcing the non consenting adult to act as one is a false premise. To conclude, I posit that, while the argument was convincing and made some very good points, it is a false equivalence. If I am misunderstanding the definition, please let me know, but I do not see in any respect how the two situations are similar.

@T Mac: All of what you just wrote aside, the violist argument as you presented it is not a false equivalence because no equality is being claimed. This is an analogy that is presented and as such, all analogies by definition are not equal situations but "like" situations. You can argue that it is a weak analogy based on your points above, but not false equivalence.

@Bo Bennett, PhD: ah, thank you for the explanation. I get where my misunderstanding was coming from now. This conversation has been enlightening.

Is this a false equivalence fallacy?

AOC doesn't know what a garbage disposal is. Therefor she is a terrible politician.
