Remember, ENFPs are driven by an Fi compass --> that seems completely 'irrational' and 'illogical' to people who do not have that person's particular Fi reader and thesaurus.
As far as 'classic logic' - it's been mentioned elsewhere but ENFPs are well represented in the ranks of 'the gifted'. I know when I take puzzle challenges and play 'logic games' and such I do pretty well. As well or better than my INTP brother who, while damned annoying, is 'intelligent' in the textbook sense. There are lots of kind of 'logic' of course and many kinds of intelligences.
Being good at 'logic' is subjective for now.
I am a great debater though in the general and competitive sense. In classic parliamentary style debate, you have to be able to follow other people's threads of thought, rebut, keep track, etc. Actually, the reason I'm a great debater is because I refuse to concede my point if I truly feel I am correct. LOL.
Also, just because I know the popularly ceded 'logical next step' doesn't mean I want to take it. I know the way I live my life probably doesn't seem 'logical' to some people and that's fine. Life is not lived by logic, it's lived by whatever you want it to be.
So I think I'm good at 'logic' but I don't really adhere to it unless I *feel* like it.
