Yeah, that makes sense and was also my (less informed) impression. I’ve said so in the post:
As others[2] have also pointed out, I think we’d get the best sense of net wild animal welfare not from abstract arguments but by studying individual animals up close. I don’t think anyone who works on these topics really disagrees (my post is directed more towards non-experts than experts). Still, I have seen versions of the Evening Out Argument come up here and there in discussions, and I got the impression that some people [[in EA]] put a lot more weight on these sorts of considerations than I would.
I think it’s a typical EA thing, having too high of a regard for specific types of arguments (especially when the empirical work is being done in places).
(But then my also somewhat abstract/philosophical counterarguments should at least land well with an EA target audience! :))
Thanks!
Playing devil’s advocate:
Even if we grant that punishment is more effective than positive reward in shaping behavior, what about the consideration that, once the animal learns, it’ll avoid situations where it gets punished, but it actively seeks out (and gets better at) obtaining positive reward?
(I got this argument from Michael St Jules—see point 4. in the list in this comment.)
Edit: And as a possible counterpoint to the premise, I remember this review of a book on parenting and animal training where it says that training animals with attention on positive reward (but also trying not to reward undesired behavior) works best. That’s a different context than evolution’s, though.
For what it’s worth, I agree with the sentence in your linked draft that “[...] not getting a reward may create frustration, which is nothing but another form of pain.”
But overall I’d be pretty hesitant to give much weight to theoretical arguments of this sort, especially since you can often think of counterconsiderations like the one above.
