Negative effect means that when we know others, our impressions of positive and negative information are always unequal, and extreme emotions usually contain something. Many things are not so heinous, but when you are emotional, you always feel that the situation is so serious that you have to take an extreme action to overcome it. And when you come out and look back, you find it's just a piece of cake. The thing itself has not changed, but your perspective has deceived you. The emergence of "negative effects" is often influenced by personal negative emotions and perspectives. If we look at things from a positive perspective, the world will be brighter.
