“”This car weighs just under a thousand kilos. A Lotus Elise weighs in at just under a thousand kilos. That makes this car a Lotus Elise!

“”Determinists say humans are exactly like computers [in causation] but they only ever debate people.

The association fallacy is an informal version of the fallacious argument known as affirming the consequent. It consists of promoting an opinion or philosophy by recounting the values a specific person or a group that held that opinion or philosophy. The Richard Hammond quote above may have been made in jest, to appeal to the stupidity of such associations, but it is an extremely common, and often easy fallacy to make. It is, to an extent, a version of a non sequitur.
This fallacy can be done in either a positive or negative (derogatory) way. In both cases, it is equally fallacious. This is best demonstrated by common examples.
- A is a member of group B
- A is a member of group C
- Therefore, group B is C.

Stefan Molyneux's argument against determinism:
- Determinists say humans are identical to rocks in causation.
- Determinists debate people.
- They're doing the same thing as debating rocks.
Molyneux elaborates on this by using the analogy that if a group of oranges were identical, "it wouldn't matter which one I eat"; without realizing the irony that according to his logic, oranges are identical to computers because of deterministic causation so he should eat computers.
 Positive uses
Positive association is called honor by association.
In this case, the fallacy implies that the good things that people associate with Martin Luther King came from his being a Baptist. While this may, in part, be true, it is fallacious to state that all Baptists will be good, or that someone becoming a Baptist will become good. In politics, the association fallacy is often subtly combined a priori reasoning in a manner that is clearly nonsensical when spelled out:
- The Republican Party is opposed to raising the minimum wage.
- Abraham Lincoln was a member of the Republican Party.
- Abraham Lincoln was a good man.
- Therefore, we should not raise the minimum wage.
Although it might well be true that Abraham Lincoln was a good man, this does not reflect on the Republican Party's political ideas today, and it also misses the historical context. More importantly, such arguments take as a premise that the Republican Party ought to oppose the minimum wage and then seek to rationalize it, rather than concluding the minimum wage ought not to be raised based on empirical evidence.
 Negative uses
Negative association is called guilt by association.
- Stalin was an atheist.
- Stalin had millions of people killed.
- Non sequitur, atheism is evil.
Another classic example is the thought process used by some in the anti-nuclear movement.
- Nuclear weapons, which can destroy civilization, utilize energy from fission.
- Nuclear power utilizes energy from fission.
- Non sequitur, nuclear power is bad.
Negating the positive use above
With most negative uses of association fallacies, it relies on fear. In the former case, many of the acts that Stalin made are inherently fearful, but it is doubtful whether he ordered them on account of his atheism or in the name of communism. Even if this doubt wasn't present, to attribute the negative aspects of Stalin to these beliefs is fallacious as the beliefs themselves say nothing about mass murder. This is similar to how, in a post 9/11 world especially, moderate Muslims have been subject to unfortunate associations due to the acts of fundamentalists and Jihadists. In the latter case, the fear of nuclear weapons inspired by Cold War propaganda is used to suggest that nuclear power should be similarly feared, because it uses the same physical process, even though the process of fission itself is morally neutral.
An example of Conspiracy Theorists demonizing (no pun intended) a debunker:
- Stanton LaVey is a LaVey Satanist
- Joe Ronan is friends with Stanton LaVey.
- Therefore Joe Ronan is a Satanist and a Shill.
Cranks often say, "But Galileo was persecuted in his day, and he was right!" when their ideas come under attack.
This follows the form:
- Galileo was persecuted for his beliefs
- Galileo was right
- I'm persecuted for my beliefs
- I'm right
This is not even wrong -- Galileo was persecuted not because people disagreed, but because if he was right it would contradict social thought.
The construction "x-baiting," where x is an undesirable ideology or group of people, is often used when a speaker attempts to make an association (real or imagined) between a person or group and x. Examples include:
- Green-baiting, associating all environmentalists with ecoterrorists.
- Race-baiting, making racially divisive comments or associating a person of a certain race with some wingnut (e.g. associating black people with Louis Farrakhan).
- Red-baiting, connecting a person to some (usually imaginary) communist plot or associating him with communism in some way.
- Terrorism-baiting, making spurious accusations of the subject's relation to a terrorist organization.
- Greece-baiting, connecting one's fiscal situation to that of Greece.
- Pink-baiting, linking everything bad to homosexuals and homosexuality.
- Hitler-baiting, connecting anything interpreted as bad to Nazism. See Godwin's Law.
