Science And Superstitions
Generally speaking, science is fundamentally based on testable observations. Testability entails that a hypothesis be falsifiable and that it also be reproducible . New discoveries sometimes alter our understanding which is the basis of our previous theories, hence such theories are replaced by new ones. Superstitions lack testability and are generally based in unsupported assumptions. It is therefore not permissible to hold superstitious beliefs. As a side note, some of the modern science is also based on unsupported assumptions. This is, however, actively debated in the philosophy of science and should not concern a common person.
