First, I think your Ne is constantly on overcharge or something. That's probably where most of that comes from. And yes, Fi would likely be better than Ti at problems involving human elements. And three, my Ti is perfectly capable of dealing with "fuzziness". In fact, that's kinda it's job. To sort out fuzziness. Possibly it could be that you are more likely to go with whatever answer Ne spits out, and your ENTP coworkers take more time to get a Ti model. If they went with Ne more, possibly they could be just as fast as you.
