So if you find you ARE that friend, presumably you’d have no fear of stepping in front
of that gun barrel yourself for a few million flips right afterwards.
I don’t believe so. While the person who underwent the experiment has a completely convincing proof of MWI+QTI, the friend doesn’t. What he saw is just as unlikely under MWI as it is under Copenhagen.
If you didn’t believe in MWI+QTI (i.e. had very low priors for), and you saw your friend claim to do a billion coin flips and not get shot, then even if you “refuse” to significantly increase your belief in MWI+QTI, wouldn’t you at least increase your belief in the possibility that the gun is broken, and thus would not shoot you?

I would assume that the gun was broken and thus would not shoot me.
