"BTW, as I understand it, honest scientists do NOT work from fixed-theories either, right?"

There's a difference between being open-minded and being stupid. Honest scientists know the difference between conclusions derived from their scientific principles and methods and those that are personal opinions.

The part relating to "fixed-theories" is ambiguous. Scientists are open to new ideas and new data, if not as individuals, then as a collective. That doesn't mean that every stupid pseudo-theory is considered likely.
