The murderer of the "Lan incident" is herself. Why doesn't everyone believe it?

Because people are subjective, most people who don't want to break their original thinking system don't want to admit that they are wrong. Just like Lan's case, it is obviously something that can be explained by science, but they are unwilling to admit their mistakes and subvert the worldview they have established for themselves because of it.

Let's revisit the Lan incident. This Chinese Canadian woman made a series of incredible behaviors in the elevator of a local high-end hotel. Finally, she mysteriously disappeared and was found in the water tank on the roof of the hotel. In fact, apart from the monitoring pictures taken in the elevator, this is a case that needs to be investigated, but it hangs, and her strange actions finally disappear under the condition of monitoring everywhere. Then netizens all over the world began to think differently. Some people think that her behavior is abnormal. Others said that the postcard she sent to her friends was actually asking for help. In short, all this points to mysterious events. But she suffered from bipolar disorder before her death, and few people mentioned it. It is not impossible for bipolar patients to choose to leave this world because of some things.

What is the truth of the incident? Up to now, there has been a concrete conclusion, or it has been officially explained many times. She suffers from bipolar disorder and once said on her blog that life is hopeless and she has bad ideas. It was because she didn't intervene her emotions in time that she did such a thing. However, not many people believe that she died unexpectedly because of mental illness. But there is no trauma to the body, and all behaviors can be explained by science, including all the evidence collected before pointing to her own mental problems, but in this way, some people still think that this is metaphysics and an unexplained mysterious event.

Why doesn't everyone believe what I just said? People are subjective, but this subjectivity actually has a confirmation bias. What does this sentence mean? In other words, after summing up an answer, people will continue to collect information that is beneficial to them, and they will be more inclined to collect information about this answer themselves. For them, things that don't meet the answers they have already decided are not credible and will not be adopted. In the era of big data, the information they actively collected and the information passively pushed to them by big data further deepened the recognized answers. This is why in this matter, no matter whether the truth appears or not, some people just think that the truth is incorrect and the illusion in their hearts is correct. Although people are rational, few people can draw the most just conclusion without themselves, which is also the self-protection mechanism of human beings. So it is understandable, but it is really not advisable to boil it down to metaphysics.
