What's the atonym for related information?

Question

I can't remember this word, it's been on the tip of my tongue for days. I am sure that this word exists but there's no synonym results I could find on Google. It means something like the inverse of correlation/evidence, "freak occurrence" possibly.

It's a word used to say something to the effect of, "you're referring to something as though it's connected". But that word describes the claim in a single word: "X information". A great example is something like;- person A sees person B in a car with a dog and then goes on to conclude that many people might drive with dogs in the car. The observation is "unrelated" to the reality or something similar, yet person A took it to have a connection and for there to be some underlying explanation. This event itself (not the observation) is an X. Talking about the event is using X information and is not very scientific.

edit: I found it. (anecdotal/anecdote, "anecdotal information")

Answer 1

The first word that comes to mind for me is "irrelevant." You might also be thinking of "superfluous" which conveys a bit more of the idea that the information is unnecessary noise. If you count "non-germane" as a single word it probably fits your description pretty well also. A thesaurus hit might give you other words like "extraneous" or "peripheral" that may also get at your desired meaning.

Answer 2

Mistaken / false inference is one possibility; or perhaps coincidence, unrelated event / phenomenon, presumption, generalization, extrapolation or jumping / leaping to conclusions.

Answer 3

The example provided in the question is insufficient. One can draw such an incorrect inference for various reasons:

• generalization
• conjecture
• drawing false inference from true premises (invalidity)
• misinfer something in general.

Answer 4

Your disparate example sounds like a syllogism:

"conclusion," "inference") is a kind of logical argument that applies deductive reasoning to arrive at a conclusion based on two or more propositions that are asserted or assumed to be true.

In its earliest form, defined by Aristotle, from the combination of a general statement (the major premise) and a specific statement (the minor premise), a conclusion is deduced. For example, knowing that all men are mortal (major premise) and that Socrates is a man (minor premise), we may validly conclude that Socrates is mortal. Syllogistic arguments are usually represented in a three-line form (without sentence-terminating periods):

All men are mortal.

Socrates is a man.

Therefore, Socrates is mortal

The word "therefore" is usually either omitted or replaced by the symbol "∴"
