Scientists often believe or disbelieve theories in the scientific world, just as Einstein initially rejected a great deal of QM based on his view of things.
So why is this a problem? If not for skepticism, we would still be living in caves. All robust theories are incomplete. This is why scientists constantly tinker with theories, refining, redefining, corralating, investigating, rectifying etc.
