What's the difference between psychology and constellations? Why do people who believe in psychology reject constellation personality analysis?

Psychology is a science, and science needs to be analyzed and verified with a rigorous and cautious attitude. Constellation can't be verified repeatedly, can't be falsified, and has too many contradictions, so it doesn't belong to science.

For example, a psychological analysis of a person's behavior requires a detailed analysis of environmental influences, interpersonal relationships, past experiences, personality factors and other information.

Constellations only need to know a person's date of birth to do simple gender and behavior analysis, which is inaccurate.
