What is the value of credibility under this way of thinking? If someone has a history of delivering but you think their idea is bad, do you give them a chance? Or vice versa, if someone has great vision and a history of failing, do you give them a chance?

Is there no weight to credibility? Similarly, if Terry Tao refuses to even read your ideas unless you have the right professional look, is that cruelly dismissive and arrogant?
