"Long-Termism" vs. "Existential Risk"

Spreading wild animals to space isn't bad for any currently existing humans or animals, so it isn't counted under thoughtful short-termism or is discounted heavily. Same with a variety of S-risks (e.g. eventual stable totalitarian regime 100+ years out, slow space colonization, slow build up of Matrioshka brains with suffering simulations/sub-routines, etc.)

Book Review: Deontology by Jeremy Bentham

"I really love you!"

"You mean you enjoy my company a lot?"

"Well of course, and I want you to be happy."

"I enjoy your company and want you to be happy as well, so I guess I love you too!"


That doesn't seem creepy to me. In fact, I've had this discussion with myself before (about what it means to love someone) and (1) liking them and (2) wishing them happiness, are about what I got.

As for people existing, I think the first 2 levels are clearly true regardless of axiology. As for 3, I think a hedonist could say something like "Person X gives me great pleasure, a good thing" and "Person X is happy, another good thing". All 4 of those statements (1, 2, and my revised versions of 3) seem totally fair and non-weird to me, but perhaps I'm misunderstanding you.

What should I study in undergraduate?


I'm new to EA, and a college freshman at my local public state school. Currently, I'm taking some low-level math, philosophy, and computer science classes and enjoyed them. I don't think I fit the 80,000 hours profile of "talented, driven, and ambitious", but I do want to increase the total sum of pleasure over pain in the universe and think what I get a degree in probably matters for that project.

Some thoughts on vegetarianism and veganism

This is pretty amusing Matt, unsure why you've been down-voted here. More seriously, rationalization of one's preferences is a real trap!

Some thoughts on vegetarianism and veganism

This seems at least a bit different from going veg*n in "private" so to speak. If you stop eating meat and tell no-one not immediately impacted by this choice, why would that lead to scaring off people from EA?


Granted, you seem to be talking about a large portion of EAs being veg*n, a large enough portion that meat is not served at the events and a potential new-comer would feel like the only omnivore there. I think this cuts against EA organizations advocating for veg*nism and towards providing non-veg*n food at EA events, but not necessarily against one's own personal consumption choices.

Some thoughts on vegetarianism and veganism

I find the argument for veg*nism based on expected value fairly compelling. In a developed nation, factory farming is dominant. In a factory farm, it seems like ~all animals have net negative lives. Not eating animal products reduces demand for those animal products, leading to less animals with net negative lives being raised on factory farms.


You say that this value isn't very big, and perhaps it isn't. But neither is the cost? Veg*n food in my experience is as healthy, potentially cheaper, and similarly effortful to make as home-cooked non-veg*n food. 


You mention moral licensing. My prior for social science research being true is pretty low so I'd tend to think this effect is small or non-existent. A 5-second google search revealed a meta-analysis of ~90 studies studying ~7000 participants, only including those with a control. They found the magnitude of the effect to be a Cohen's d of .31 which is small. Also unpublished studies had smaller effect sizes than published ones, which makes me more skeptical.

You also mention health/energy costs. As far as I know, the consensus is that well-planned diets whether veg*n or not are all healthy, with some (crappy? I haven't looked into it) research that veganism is good for you. Vegan for Life by Jack Norris and Virginia Messina gives this conclusion and seems to be right. I hope someone will tell me if this opinion about health is wrong though!

Welfare Estimation 101: Money is not Fungible

As far as I can tell, Richard Bruns is talking about the quality-adjusted life year or QALY. 


The reason it is a year is essentially arbitrary, a year is decently long without being too long for the purposes of public health where QALYs first got used.

The way we deal with "healthy, happy, and flourishing" as a single unit is much trickier. For traditional QALY calculations, researchers simply ask people how they feel when experiencing certain things (like a particular surgery or a disease) and normalize/aggregate those responses to get a scale where 0 quality is as good as death, 1 is perfect health, and negative numbers can be used for experiences worse than death.


Then you multiply quality by quantity. The Wikipedia article on this is good and goes into more depth: https://en.wikipedia.org/wiki/Quality-adjusted_life_year



Note: I don't know how Bruns intends to measure quality of life yet, I expect we'll have to wait.

Thoughts on whether we're living at the most influential time in history

If a long future is not plausible, a uniform prior of hingy-ness makes sense even when considering the non-negligible amounts of x-risk we seem to observe now.

It also offers an explanation for us being in an 'early' time, there is no later time we could have been born in. In other words, humanity doesn't have much time left so being born a long time into the future is the implausible bit.

Shouldn't this doomsday argument have a higher prior probability than a sudden decline in x-risk or simulation? We've seen extinction events happen before, but not the other two.
