Science should be a profession, not a priesthood.
Most people prefer experts, of course, especially when it comes to health care. As a surgeon myself, I can hardly object to that tendency. But a problem arises when some of those experts exert outsized influence over the opinions of other experts and thereby establish an orthodoxy enforced by a priesthood. If anyone, expert or otherwise, questions the orthodoxy, they commit heresy. The result is groupthink, which undermines the scientific process.
