Not really. It's easy to think of reasons why something won't work. It requires an insanely small amount of effort compared to finding a way to make something work. "Reasons why not" are a dime a dozen.

I certainly think there is. I haven't collected any evidence, but I wouldn't be surprised if those who find success are always looking for reasons why something will work, and those who run into failure are always looking for reasons why something won't work.
Now, to be fair, thinking of reasons "why not" does have its specialized use cases. Safety, for instance. But even then, that requires thinking outside of the box for unusual failure situations.
