When you pick up an onion, whether white, red or yellow, it is understood that the anatomy of that onion is one made up of multiple layers surrounding an inner core. Now picture the scientific method as a means of pulling each and every layer black slowly and carefully with the main goal being exposing what's underneath. This process is meant to happen over and over until the core is reached. Whether the layers make one feel good about themselves is irrelevant. Whether the core of the onion ends up supporting your initial hypothesis, is irrelevant. The only thing, in the end, that ever really matters - is the truth.
