How to prove the authenticity of the constellation with big data?

Big data has proved that constellations are not credible. Everyone has his own personality. However, many people know his own constellation and understand it. Oh, my personality is the same, and there are several different ones. Oh, my horoscope should be like that, so it will gradually become like that. So people who believe in the constellation will gradually become the character of that constellation. People who don't believe in the constellation like me don't know what my constellation should be. There must be many differences in comparing constellations now, because I have formed my own unique personality, not the personality that my constellation should have.
