The quote in that link makes a good point: If one gives you an excuse to be lazy, then you might be privileging the hypothesis; it could be that it was only raised to the level of attention so that you can avoid work. Thus, the lazy choice really does get a big hit to its prior probability for being lazy.

But it's still false that the other one is probably right. In general, if a human is choosing between two theories, they're both probably insanely wrong. For rationalists, you can charitably drop "insanely" from that description.
