I.e. I agree with your analysis that they (and artemisinin treatment) are great and worth doing if the local governments don't tax or steal them (in various ways) too intensively.

Douglas,

It's $1000 per life not per net, because in most cases nets or treatment won't avert a death.

g,

There's plenty of room to work on vaccines and drugs for tropical diseases, improved strains of African crops like cassava, drip irrigation devices, charcoal technology, etc.

kebko,

The best interventions today seem to cost $1000 per life saved. Much of the trillion dollars was Cold War payoffs, bribing African leaders not go Communist, so the fact that it was stolen/wasted wasn't that much of a concern.

I tend to prefer spending money on developing cheaper treatments and Africa-suitable technologies, then putting them in the public domain. That produces value but nothing to steal.

Regarding g's point, I note that there's a well-established market niche for this sort of thing: it's like the popularity of Ward Connerly among conservatives as an opponent of affirmative action, or Ayaan Hirsi Ali (not to downplay the murderous persecution she has suffered, or necessarily to attack her views) among advocates of war against Muslim countries. She'll probably sell a fair number of books, get support from conservative foundations, and some nice speaking engagements.

Steven,

Information value.

g,

This is based on the diavlog with Tyler Cowen, who did explicitly say that decision theory and other standard methodologies doesn't apply well to Pascalian cases.

Pablo,

Vagueness might leave you unable to subjectively distinguish probabilities, but you would still expect that an idealized reasoner using Solomonoff induction with unbounded computing power and your sensory info would not view the probabilities as exactly balancing, which would give infinite information value to further study of the question.

The idea that further study wouldn't unbalance estimates in humans is both empirically false in the cases of a number of smart people who have undertaken it, and looks like another rationalization.

The fallacious arguments against Pascal's Wager are usually followed by motivated stopping.

"that equally large tiny probabilities offer opposite payoffs for the same action (the Muslim God will damn you for believing in the Christian God)." Utilitarian would rightly attack this, since the probabilities almost certainly won't wind up exactly balancing. A better argument is that wasting time thinking about Christianity will distract you from more probable weird-physics and Simulation Hypothesis Wagers.

A more important criticism is that humans just physiologically don't have any emotions that scale linearly. To the extent that we approxim... (read more)

Robin,

What standard do you use to identify "good tastes and values" to be open to?

This looks like a relatively clear case of excessive narrative-to-signal.

And again, babyeating norms need to invade in a similar fashion, and without norms other than baby-eating, the communal feeding pen selects for zero provisioning effort.

"If most of the total cost of growing a child lies in feeding it past the rapid growth stage, rather than birthing 50 infants and feeding them up to that point,"

From their visibility in the transmitted images it seems the disproportion isn't absurdly great. Also, if the scaling issues with their brains were so extreme, why didn't they become dwarfs? One big tool-using crystal being versus 500 tool-using dwarfs of equal intelligence seems like bad news for the giant.

"I fear that you have not managed to convince me of this. If the general idiom of children in pens is stable, then the adults contributing lots and lots of children (as many as possible) is also evolutionarily stable."

I have a tribe of Babyeaters that each put 90% of their effort into reproducing, and 10% into contributing to the common food supply of the pen. This winds up producing 5000 offspring, 30 of which are not eaten, and are just adequately fed by the 10% of total resources allocated to the food supply. Now consider an allele, X, that di...

Michael,

I guess it depends on whether the fantastic element can adequately stand in for whatever it is supposed to represent. Magic starship physics can be used to create a Prisoner's Dilemma without trouble, since PDs are well understood, and it's fairly obvious that we will face them in the future. No-Singularity and FTL, so that we can have human characters, are also understandable as translation tools. If Babyeaters are a stand-in for 'abhorrent alien evolved morality' to an audience that already grasps the topic, then the details of their evolution do... (read more)

Eliezer, you're right that the coordination mechanisms would be imperfect, so it's an overstatement to say NO babyeating would occur, I meant that you wouldn't have the 'winnowing' sort of babyeating with consistent orders-of-magnitude disproportions between pre- and post-babyeating offspring populations.

Nits. I'd say there are probably lots of at-least-Babyeater-level-abhorrent evolutionary paths (not that Babyeaters are that bad, I'd rather have a Babyeater world than paperclips) making up a big share of evolved civilizations (it looks like the great maj... (read more)

I wonder about the psychological mechanisms and intuitions at work in the Babyeaters. After all, human babies don't look like Babyeater babies, they're less intelligent, etc. Their intellectual extension of strong intuitions to exotic cases might well be much more flexible than their applications to situations from the EEA, e.g. satisfying them by drinking cocktails containing millions of blastocysts. Similarly, human intuitions start to go haywire in exotic sci-fi thought experiments and strange modern situations.

"I don't understand why you think that provisioning your own offspring is a group advantage." If parents could selectively provision their own offspring in the common pen, then the group would not be wracked by intense commons-problem selective pressures driving provisioning towards zero and reproduction towards the maximum (thus resulting in extermination by more numerous tribes).

Actually, babyeating in the common pen isn't even internally stable. Let's take the assumptions of the situation as given:

1. There is intertribal extermination warfare. Larger tribes tend to win and grow. Even division of food among excessive numbers of offspring results in fewer surviving adults, and thus slower tribal population growth and more likely extermination.
2. All offspring are placed in a common pen.
3. Food placed in the common pen is automatically equally divided among those in the pen and adults cannot selectively provision.
4. Group selection has res
