Reminds me of the motto "Strong Opinions, Weakly Held". There's no point having a blurry opinion, or not expressing what you believe to be the most likely candidate for a good way forward, even if it's more likely by only a small margin. By expressing (and/or acting on) a clearly expressed, falsifiable opinion, you expose it to criticism, refutation, improvement, etc. And if you hold it weakly, then you will be open to reconsidering. Refusing to make up your mind, and kindof oscilating between a few options, perhaps waiting to see where the wind blows, has its advantages, but especially when it comes to getitng things done, is most often a clear loser. Despite this, our brains seem to prefer it instinctively, maybe due to some ancestral environment echoes about being proven wrong in the eyes of the tribe?
