I probably should have clarified that I was responding to the content of the parent comment rather than the submission itself.

I think this is just the slop of language, but in this case it's obscuring all the important details so excuse me for being a bit pedantic.

Forming and accepting a hypothesis are very different things. You can't just come up with a new hypothesis after looking at some data and then immediately accept it because the data supports it.

It would absolutely be incorrect to look at the original data, form an alternate hypothesis, and then immediately go on to suggest it is an equally good explanation as the original hypothesis.

You don't have to accept the original hypothesis if you think the experiment is flawed, and you're free to propose any hypothesis you want, but that's the limit without new data.
