The political right is obsessed with minimizing Type II error. They feel it's better to miss good research results than to have the wrong people performing the research or chasing the wrong ideas to start with (a false negative) and the further to the right they are on the spectrum, the more important minimizing the wrong people and ideas becomes. This leads to less discovery and successes because more research gets falsely rejected at the funding level.

The political left, of course, is the opposite and obsesses over Type I error. Accepting the wrong people and ideas is less important than getting good results. This leads to things like Lysenkoism, but also tends to reject less successful research, given the other checks and balances built into a healthy system.
