No, it doesn't. In fact - the opposite is true. Belief is one of the main obstacles on the way to knowledge. If you believe in something you're particularly prone to all sorts of errors, like confirmation bias, which is why scientists are expected to leave their beliefs at the door, when entering the labs.
