The observation

O1) You are not hiding in the kitchen.

it is not really an evidence for H1 and H2 otherwise it is an evidence for any event accept that “I’m not hiding in the kitchen” — which, in the end, tells me nothing (some evidence!!! )

According to your logic, O1 is also an evidence in favor of

H3: I died and I’m not hiding anywhere
H4: I stopped playing and I went home
H5: I’m travelling to to hide in China
H6: etc.

So?

I think you are still missing the problem with relying on quantitative analysis (observations and counting) in problems that require qualitative inference. BTW, I mentioned this in another reply:

Another serious problem with the quantitative (Bayesian) analysis is that observing a black but non-raven is a negative evidence for “All ravens are black” (plug the data in the formula to verify that!) which is also ridiculous.
