Stupid Questions Open Thread Round 2

OpenThreadGuy

From Costanza's original thread (entire text):

This is for anyone in the LessWrong community who has made at least some effort to read the sequences and follow along, but is still confused on some point, and is perhaps feeling a bit embarrassed. Here, newbies and not-so-newbies are free to ask very basic but still relevant questions with the understanding that the answers are probably somewhere in the sequences. Similarly, LessWrong tends to presume a rather high threshold for understanding science and technology. Relevant questions in those areas are welcome as well. Anyone who chooses to respond should respectfully guide the questioner to a helpful resource, and questioners should be appropriately grateful. Good faith should be presumed on both sides, unless and until it is shown to be absent. If a questioner is not sure whether a question is relevant, ask it, and also ask if it's relevant.

Meta:

How often should these be made? I think one every three months is the correct frequency.
Costanza made the original thread, but I am OpenThreadGuy. I am therefore not only entitled but required to post this in his stead. But I got his permission anyway.

I obviously do not understand quantum mechanics as well as I thought, because I thought this comment and this comment were saying the same thing, but karma indicates differently. Can someone explain my mistake?

The first comment says that the double slit experiment is feasible under both hypothesis, but the second adds on that it is just as likely with MWI as waveform collapse.

Analogy: There are two possible bags arrangements, one filled with 5 green balls and 5 red balls, and the other with 4 green balls and 6 red balls. It's true that drawing a green ball is consistent with both, but it's more likely in the with first bag than the second.
