Justice previals itself in the long run. Even though someone seems to be successful (graduate early, get a faculty position early or get a faculty position at the good reputation university, and so on), time will reveal the person's true capabilities in the end. Pseudo-scholars who just have a bright background and do not have an actual research ability are sorted out and forgotten as soon as he/she left academia.
I agree with Dennis "true" is not clear. But if you intend to know what can be considered the boundary between what is "scientific" or not remember that:
SCIENCE IS A METHOD
Before Galileo people used to make philosophy, speaking about possible theories without measuring with experiments.
Galileo formalised the need to make experiments in a open, verifiable and repeatable way, before making "scientific" statements
