Truthfully, I hold those ideas a little more confidently than purely "for the purposes of discussion", but I suspect you at least understand that the real-world usage of "hypothesis" is quite broad.

I'm kind of tickled at the idea that a "hypothesis" is some hyper-specific thing with trappings of "credibility", and that anything less would be an insult, like we're not all just a bunch of nerds arguing on the internet. It's also kind of sad, though. This is why computer people need liberal arts education.
