I think a lot of what people are missing is around spoken techniques.
Recognising ad hominem attacks.
Recognising straw-man arguments.
Recognising circular reasoning.
Spotting embedded assumptions or premises in points.
Being numerically literate enough so that big numbers have context.
Yes, these things apply to texts also, but they can fly past you when somebody is speaking. You can’t take 30 seconds to notice that somebody is arguing against something which wasn’t said by the opposition. It has to be a reflexive “hang on a minute! That’s BS”.
