Rationalizing bad behavior is an NF thing? NFs are somehow better at it? Humans rationalize bad behavior. It's theoretically conceivable that an NF with Fi may use morality to do it (although I've never seen anyone do this... perhaps you should give me an example of it).
Points:
1. Everything I've posted (or will post) in this thread has been generalization with consideration to both groups of people and tendencies. I'm often misunderstood as saying things "are..." as opposed to saying things "often tend to be..." It's the latter.
2. It is also primarily detached, abstract analysis in the INTP style. The analysis is its own goal. I might as well be discussing a mental creation as actual people.
3. I would say NFs have less of a
need to rationalize than others. To use function terminology, their dominant judging function is Feeling, so if something
strikes the NF as right, it will likely forever be
considered to be right. There is less of a felt need to make excuses for actions. SFs tend to be less influenced by the concept of chasing ideals, and therefore show dissimilar inclination here.
4. I will invent an example: an ENFP has plans to do something with a person. They then find out their favorite band is playing the same day, cancel the plans, and feel no guilt. They have followed their heart, and feel justified in doing so, which leads to...
5. All types can demonstrate behavior similar to this. As stated earlier, it is the method of justification which is somewhat unique.
