Many scientists today refuse to let facts get in the way of their theories.
That is a complete myth and would be irrelevant even if it were true. Regardless on what your hypothesis is, in science you present evidence for or against it. Others can verify your claims. That is why, in science, frauds are eventually exposed, unlike virtually anything else. This is also why science has such a strong reputation.
By the way, you are confusing the difference between a hypothesis, a scientific theory and the layman theory.
