A lot of people out there do not listen to learn or share viewpoints or out of genuine interest for the other being, but to get information that they can later use against you. People with real interests (nerds) should be particularly careful when talking to most people because nerds don’t understand such intent, which is why I try to not share my interests or similar personal information when I don’t sense certain personality traits. Being shut up about yourself makes most people out there mad because they view a conversation as a “trade” and can’t expect a later dopamin fix if you don’t give them your share, but who cares.
