People who purport to be of a scientific philosophy will respond with skepticism to claims of things said to be paranormal, metaphysical, or supernatural. What is often misunderstood about scientists, however, is that a scientist will not necessarily dismiss these things without cause. Instead, a scientist will search for ways to explain these things in terms of what is normal, physical and natural as well as what can be empirically tested.
That which is based on belief is not of much interest to a scientist. In fact, a scientist does not have beliefs at all, preferring instead to form opinions based on the best empirical evidence of the day.
A scientist might speculate on things not understood, but should freely admit that such thoughts are mere speculation. A scientist also knows that the science of today is not able to explain many things, and that much of what is known could be wrong, but will be better explained by evidence gathered in the future.
