This almost reads like an attempt at a reductio ad absurdum of worrying about animal welfare, like you are supposed to be a ridiculous hypocrite if you think factory farming is fucked yet are indifferent to the cumulative suffering caused to termites every time an exterminator sprays your house so it doesn't crumble.

Relying on the mean estimate, giving a dollar to the shrimp welfare project prevents, on average, as much pain as preventing 285 humans from painfully dying by freezing to death and suffocating. This would make three human deaths painless per penny, when otherwise the people would have slowly frozen and suffocated to death.

Dog, you've lost the plot.

FWIW a charity providing the means to stun shrimp before death by freezing as is the case here isn't indefensible, but the way it's framed as some sort of an ethical slam dunk even compared to say donating to refugee care just makes it too obvious you'd be giving money to people who are weird in a bad way.

If we came across very mentally disabled people or extremely early babies (perhaps in a world where we could extract fetuses from the womb after just a few weeks) that could feel pain but only had cognition as complex as shrimp, it would be bad if they were burned with a hot iron, so that they cried out. It’s not just because they’d be smart later, as their hurting would still be bad if the babies were terminally ill so that they wouldn’t be smart later, or, in the case of the cognitively enfeebled who’d be permanently mentally stunted.

Not that I'm a super fan of the fact that shrimp have to die for my pasta, but it feels weird that they just pulled a 3% number out of a hat, as if morals could be wrapped up in a box with a bow tied around it so you don't have to do any thinking beyond 1500×0.03×1 dollars means I should donate to this guys shrimp startup instead of the food bank!

Apologies for focusing on just one sentence of this article, but I feel like it's crucial to the overall argument:

... if [shrimp] suffer only 3% as intensely as we do ...

Does this proposition make sense? It's not obvious to me that we can assign percentage values to suffering, or compare it to human suffering, or treat the values in a linear fashion.

It reminds me of that vaguely absurd thought experiment where you compare one person undergoing a lifetime of intense torture vs billions upon billions of humans getting a fleck of dust in their eyes. I just cannot square choosing the former with my conscience. Maybe I'm too unimaginative to comprehend so many billions of bits of dust.

lol hahah.

Ah you see, the moment you entered the realm of numbers and estimates, you’ve lost! I activate my trap card: 「Bayesian Reasoning」 to Explain Away those numbers. This lets me draw the「Domain Expert」 card from my deck, which I place in the epistemic status position, which boosts my confidence by 2000 IQ points!
