It is difficult for me to ascertain when the person I am communicating is using a logical fallacy to trick me into believing him or doubting my judgement, even when I realise it hours after the argument.

I have seen countless arguments in Reddit threads and I couldn’t figure out who was in the right or wrong unless I looked at the upvote counts. Even if the person is uttering a blatant lie, they somehow make it sound in a way that is completely believable to me. If it weren’t for those people that could exactly point out the irrationality behind these arguments, my mind would have been lobotomised long ago.

I do want to learn these critical thinking skills but I don’t know where to begin from. I could have all these tips and strategies memorised in theory, but they would be essentially useless if I am not able to think properly or remember them at the heat of the moment.

There could be many situations I could be unprepared for, like when the other person brings up a fact or statistic to support their claim and I have no way to verify it at the moment, or when someone I know personally to be wise or well-informed bring up about such fallacies, perhaps about a topic they are not well-versed with or misinformed of by some other unreliable source, and I don’t know whether to believe them or myself.

Could someone help me in this? I find this skill of distinguishing fallacies from facts to be an extremely important thing to have in this age of misinformation and would really wish to learn it well if possible. Maybe I could take inspiration from how you came about learning these critical thinking skills by your own.

Edit: I do not blindly trust the upvote count in a comment thread to determine who is right or wrong. It just helps me inform that the original opinion is not inherently acceptable by everyone. It is up to me decide who is actually correct or not, which I can do at my leisure unlike in a live conversation with someone where I don’t get the time to think rationally about what the other person is saying.

    Note that a fallacy is a reasoning flaw; sometimes the goal might be to trick you, indeed. But sometimes it’s just a brainfart… or you might be dealing with something worse, like sheer irrationality. That said:

    • look for the conclusion. What is the point that the writer is delivering? (Note: you might find multiple conclusions. That’s OK.)
    • look at what’s being used to support that conclusion. What is the core argument?
    • look for the arguments used to feed premises into the core argument. Which are they?

    Then try to formalise the arguments that you found into “premise 1, premise 2, conclusion” in your head or in a text editor. Are the premises solid? Do you actually agree with them? And do they actually lead into the conclusion? If something smells fishy, you probably got a fallacy.

    Get used to at least a few “big” types of fallacies. There are lists across the internet, do read a few of them; you don’t need to memorise names, just to understand what is wrong with that fallacious reasoning. This pic has a few of them, I think that it’s good reference material, specially at the start:

    In special I’ve noticed that a few types of fallacy are really common on the internet:

    • genetic fallacy - claiming that an argument is true or false because of its origin. Includes ad hominem, appeal to nature, appeal to authority, ad populum, etc.
    • red herring - bringing irrelevant shit up as if it supported the conclusion, when it doesn’t matter. In special, I see appeal to emotion (claiming that something is false/true because it makes you feel really bad/good) all the time.
    • oversimplification - disregarding key details that either stain the premises or show that they don’t necessarily lead to conclusion. False dichotomy (“if X is true, Y is false” in situations where both can be true or false) is a specially common type of oversimplification.
    • strawman - distortion of an opposing argument into a way that is easier to beat. Again, notice that “intention” doesn’t matter; only that the opposing argument isn’t being addressed.
    • moving goalposts - when you counter an argument, the person plops another in its place, without acknowledging that it’s a new argument. Often relies heavily on ad hoc (making stuff up on the spot to shield an argument)
    • four terms - exploiting multiple meanings associated with the same word to create an argument like “A is B¹, B² is C, thus A is C”.

    There are also some “markers” that smell fallacy for me from a distance. You should not trust them (as they might be present where there’s no fallacy, or they might be absent even when the associated fallacy pops up); however, if you find those you should look for the associated fallacy:

    • “As a” at the start of a text - genetic fallacy, specially appeal to authority
    • “Trust me” - red herring, specially appeal to emotion (once you contradict the argument there’s a good chance that the other will create drama because you didn’t blindly trust them, so the whole thing boils down to “accept this as true otherwise you’ll hear my meltdown”).
    • “I don’t understand” followed by a counter-argument - strawman. Specially common in Reddit.
    • “Actually” - red herring through trivia that is completely irrelevant in the context.
