INFP

The one definition that said INFPs are "predictable" and has "poor understanding of psychology" could not be more wrong. Clearly whoever wrote that definition has not even the slightest clue of how to interpret the MBTI. In reality, INFPs have an excellent understanding of human psychology. Usually all the NFs do (including INTJ, INFJ, INTP). INFPs are very proficient at seeing the true motives and intentions within people, they just keep it to themselves due to their Fi. And INFPs? Predictable? Nonsense! Due to their perceiving type (as opposed to judging), INFPs can be some of the most spontaneous people you could ever meet. This means that INFPs absolutely HATE predictable routines and function most optimally when doing something different for a change. Those with judging types are the predictable boring ones. INFPs by nature are NOT opportunists. Unlike an INTJ, they do NOT actively go around and seek for opportunities. They care more about authenticity rather than getting the best out of a situation. They only accept opportunities when it comes to them naturally. In other words, INFPs are the least likely ones to buy something just because it's on sale, or post something on social media just for the likes. They're the ones who tend to buy expensive organic produce as it aligns with their values. Lastly, it is important to note that INFPs are very good at handling their own emotions. This is why INFPs are often the givers of emotional support rather than receivers.
