Extended data:

"Superstition in science" or "scientific superstition" is a new type of superstition. This superstition thinks that science is omnipotent, so it advocates science and thinks that everything can be solved through science or its development, while ignoring the two sides of science. As a tool, science can not only benefit (such as medical treatment), but also cause disasters (such as high-tech crimes).

If we do not restrict science and blindly believe in science, we will destroy mankind. The way to overcome "superstitious science" or "scientific superstition" is to put science back on the right track for the benefit of mankind.
