I dunno. For someone just starting to want to think critically during discussions of when reading things, asking them to get serious in the academic pursuit of logic and argument theory might not be the way. For one, it’s probably just asking for them to get stalled in the sort of dunning kruger zone of identifying fallacies and stopping there.
Especially when such behavior is already endemic to the internet and many platforms have feedback loops designed to reward this behavior. Just dunk on 'em and move on - watch the upvotes and retweets roll in.
I definitely don’t want discourage OP from learning anything, but I do want to be careful in what direction we point a beginner.
I think maybe learning to find good sources of information and verify claims might be a better first step. That doesn’t give OP any shortcuts I’m discussions, which is good. Then they may begin to notice different patterns or forms of discussion and at that point they can start to classify them and learn about them if they see fit.
Yeah, I like that. After being able to recognize and validate claims, being able to verify the validity (at least logically if not factually) of any conclusions drawn from those claims seems like a good next step.
