On the other hand, some fallacies recur much, much more often.
Ad hominem and appeal to authority are de facto THE way humans argue with each other, with strawmanning as a very strong third. So at least learning how to spot and correct those can alone improve someone rationality.
There are though much funnier ways to learn about fallacies, Biased Pandemic being one of my favourite.
Biased Pandemic is about learning about cognitive biases. Cognitive biases are different from logical fallacies.
