Without the belief that you are right, why would you spend time pursuing something? If you're right, but nobody you talk to understands what you're saying then who is bumbling?
It's a question of perspective.
I have designed a new fusion reactor. I feel like the design has potential, and nobody seems interested in helping to evaluate it. I know there is a communication gap as well. I get different responses from everyone I talk to, and it's clear from their objections that some are dismissing the idea without understanding it. This leads to me dismissing their objections.
I know what the optics are, but still feel like I have to expend time and effort on this. If I don't do it, nobody else will.
In the end, it will work or not regardless of anyone's opinion.
