That's a very fair answer.
Do you have any sense of how you learned it? For my own part, I feel like I learned what a valid argument is, to the extent that I have learned it, almost entirely by a series of negative examples. For that matter, I'm not sure I can articulate what a valid argument is in non-question-begging terms... though to be fair, I haven't sat down and tried for five minutes.
I do not know how I learned how to argue, but I do not think it has anything to do with negative examples.
For me, it seems similar to understanding what is a valid mathematical proof (one which in theory could be expanded to following the logical rules at each step) but where you are allowed to make observations and probabilistic reasoning, all of which came naturally to me. I do not feel like I ever had any inclination to use logical fallacies, and I feel like I am quick to recognize when arguments do not make sense.
This is in contrast with cognitive bias...
