For example, if my main concern is to avoid suffering, I might only
make small bets, even in situations with very high odds of success.
In this way I avoid the pain of losing a lot of money in the few
"unlikely" worlds, though at the cost of forfeiting some gains in the
many worlds where the odds come in.
The single-world equivalent is just being very risk averse, I suppose.
But the motivation is different. In the single-world view, if I'm
risk averse I just don't want to take the risk of losing a lot of
money, even when given very good odds. In the many-world view, I know
that a future version of me is going to lose, and I want to minimize
the consequences of that loss even at the expense of limiting the
gains for the winning future-Kellys.
So the idea that I might bet more when given better odds wouldn't hold
in this case because I know that betting more is causing more
suffering for the few but inevitable losing Kellys.
And I can imagine other types of scenarios where I would bet on a
lower probability outcome, if such a bet had less severe consequences
in the case of a loss.
Though the fact that at the time you place your bet, branching may
occur resulting in different bets being placed also has to be

You're saying that there are no low probability worlds? Or only that
they're outnumbered by the high probability worlds?
I guess I'm not clear on what you're getting at with this pixel

I think I have a good grasp of 1 through 6.
