The verification is crucial though. What happens when two scientists claim they can verify a hypothesis, and two thousand scientists say they cannot?
Either two thousand scientists have screwed up badly, or just two have. Which is more likely? Lacking the skills, time & equipment to verify it yourself, who are you going to believe?
A single person can come up with a major paradigm shift that overturns our old models - but not when their results can't be reliably verified, and certainly not when their claims require simply ignoring decades of observations to the contrary.
