Not Mutually Exclusive The thinking and feeling preferences are NOT mutually exclusive. Just because INFJs have a preference for feeling doesn’t mean that they aren’t also very logical. In fact, that’s one of the most interesting secrets about this type: an INFJ can be extremely logical - so much so that some mistake him for a thinker. INFJs are first and foremost information gathering introverts, and that means their decision-making preferences are somewhat balanced; they use thinking and feeling almost equally well.
