What do you mean, against common sense? A counterintuitive understanding

1, contrary to common sense, as the name implies, is contrary to people's understanding of ordinary laws or there are some behaviors and phenomena in life that are inconsistent with people's common sense.

In real life, all kinds of known and unpredictable phenomena in the future are more or less in everyone's mind. However, everyone has a different understanding of everything. Therefore, when people have the same cognition of the same thing, and this cognition also conforms to the general law, over time, it becomes acceptable common sense.
