It’s not that we’re looking for Negative things, it’s that we are programmed with a need to survive. Discovering things that can harm us and then remembering those things is a survival instinct. At some point in the future humans will realize that the natural environment can no longer kill you nearly as easily as it did a few hundred years ago. And then theoretically it will be easier to be more optimistic about things. The one problem we have however is that humans prey upon each other. Not cannabalistically but rather monetarily and emotionally. Greed, Envy, Jealousy, and all the other negative emotions tempt us to prey upon our fellow humans. Here’s how to change it.
So basically, negative thoughts are at lower potential and it needs some work and energy to lift it to higher potential ie positive thoughts.
