Hmmm... force refresh didn't work and nor did emptying the cache. Still, the problem is probably at my end, because the same problem doesn't happen if I use I.E. instead of Firefox. Weird.
EDIT: Fixed it, it was my problem. (It was RIP being weird, which is worrying, but nothing to do with LW.)
So someone told me that Eliezer Yudkowsky predicted no 5 sigma evidence of the higgs boson, and that 6 sigma evidence had been found. A quick search found the post referred to, and a slightly longer but not particularly thorough search did not find anything discussing it.
So:

In the post below rolfandreassen sets the condition of 5 sigma evidence before 2014 and offers a bet of $25. In the post below that Eliezer accepts.
Discuss.
