Actually, why doesn’t the Hero’s world have a Counter-Force? Shouldn’t every world have something like it? How many times have our world escaped from the brink of nuclear annihilation, for example?
It’s not a question of how many times we’ve come dangerously close to annihilation, but of how obviously we’ve done so.
In Aerhien’s world, it’s obvious because, yes, it’s happened many times, but especially because it’s happened in such a way that they’ve noticed it every time, thanks to the Dust’s habit of gradual conquest and oppression.
In our world, however… well, you ask how many times we’ve “escaped from the brink of nuclear annihilation”. We don’t know, exactly, and we don’t know how close we really got to annihilation. It’s not obvious that we really got that lucky, so we had no reason to dream up a Counter-Force.
That’s a good answer, but what about the fact that none of the heroes remember a Counter-Force? Because the summoning process samples according to measure, and worlds with Counter-Force have measures that are too small? But how could the Hero have inferred that, just by knowing that he doesn’t remember a Counter-Force?
If the Counter-Force is the Anthropic principle then those worlds that have postulated Counter-Forces are essentially only those that have experienced very long sequences of unlikely events. Hence the measure of those worlds must be very small.
I’m not sure why it took me this long to realize this, but by the anthropic principle, the Counter-Force is almost certainly not the anthropic principle, but something that really exists in the world, e.g., some kind of intelligent agent, physical force, principle of magic, or rule of simulation.
Consider two worlds that are otherwise identical except that world A has a real Counter-Force, and world B doesn’t. Initially, world A has lower measure since it has higher complexity. But as time goes on, the fraction of world A that survives will massively outweigh the fraction of world B that survives. So, both the Hero and Aerhien should conclude that they’re almost certainly in world A.
I was waiting to see how long it would take for someone to point this out.
And the “answer”—which, yes, I devised in advance—is that the Dust destroys its worlds completely by compressing the probability out of them, whereupon the probability mass ends up in other worlds. Sort of like “mangled worlds” only these are “squeezed worlds” that have the reality-juice squeezed out of them.
However, anyone in a particular world thus destroyed, gets to observe the takeover of the Dust, since the Dust requires some time to actually compress that world out of existence.
Alternatively we can suppose that a majority of all worlds performing summonings are those in Aerhien’s situation: no worlds with a “real” Counter-Force, or worlds that permanently destroyed their Dust, are performing summonings in significant measure. For example, the Dust’s existence could be integral to the summoning process.
Actually, a better answer than the one I originally thought of, is that the Dust is responsible for their world splitting (in a way which causes it to increase in measure). So worlds which permanently defeat the Dust don’t increase in measure past that point, worlds in which the Dust takes over don’t summon anyone, and hence the majority of measure in worlds that can still perform summonings are those worlds which have survived but not yet defeated the Dust.
The Dust’s existence being integral to the summoning process sounds plausible—it would help to explain why there isn’t a large measure of surviving/victorious worlds engaging in cross universe commerce. Intuitively, that fits with the Dust squeezing probability mass; perhaps it creates something like a comet’s tail of evaporating improbability, some of which the summoning spell taps?
No, because our world hasn’t had as many “lucky coincidences” as Aerhien’s. It seems to me that we are not seeing more “lucky coincidences” than a typical evolved intelligent species would see, looking back on the history of its world.
I think the most we can say is that there hasn’t been a disaster in our history that would have required great luck to stop. Our world has nothing like the dust; our destruction is not nearly that intrinsically assured. So whatever coincidence saved us, anthropomorphically, would not look like an Act of Great Luck; it would look like the sort of thing that you could convince yourself in retrospect must have been more probable than it seemed at the time. Long, drawn-out sequences of individually credible chances.
The Fermi paradox says we are exceptionally lucky. But it could influence your original argument, too. I’m still not sure which way the math works out.
Because the summoning process samples according to measure
This seems like a really reasonable assumption. I mean—what sort of summoning process would not sample according to measure? What would it sample according to instead, which would not be weighted by measure somewhere along the way?

I pointed it out a few days ago :-)

Wait, doesn’t the same argument prove the existence of a God in our world that keeps rescuing life from disaster?
No, because our world hasn’t had as many “lucky coincidences” as Aerhien’s. It seems to me that we are not seeing more “lucky coincidences” than a typical evolved intelligent species would see, looking back on the history of its world.
