It's essential to avoid making sweeping generalizations about any personality type, including INFJs. People's behaviors and personalities can be influenced by a variety of factors, and not all individuals of the same personality type will act in the same way.
INFJs are known for their empathetic and sensitive nature, and they often strive to maintain harmonious relationships. This might lead some INFJs to display kindness and politeness even when they are not feeling particularly positive. They might do this to avoid conflicts or to make others feel comfortable.
However, it's essential to remember that appearances can be deceiving, and assuming that someone is "fake positive" without any concrete evidence might be unfair. It's better to approach individuals with an open mind, communicate openly, and build a deeper understanding of their feelings and perspectives.
If you have concerns about someone's behavior or intentions, it's best to address it respectfully and directly. Open communication can help clear up misunderstandings and foster genuine connections with others.
Remember, every person is unique, and it's important to treat them as individuals rather than making assumptions based on their personality type.
