I want to get generally oriented on how various common risks compare against each other. I've seen some of this come up in recent Covid discussion, but I'm interested in a good article that's like "Here's all the most dangerous stuff it's likely that you do, and here's how it breaks down for various sub-activities."

This question triggered by "the first few google results not being that good."

Scott's answer is a good one - you should read "The Norm Chronicles." But I think the question has a problem. Micromorts are a time-agnostic measure of dying, and the problem is that most risks you take don't actually translate well into micromorts.

Smoking a cigarette, which reduces your life expectancy by around 30 seconds, translates into either zero micromorts, or one, depending on how you set up the question. Increasing your relative risk of dying from cancer in 30 years isn't really the same as playing Russian roulette with a 1-million-chamber gun. Similarly, a healthy 25 year old getting COVID has about a 70-micromort risk based on direct mortality from COVID. But that number ignores the risks of chronic fatigue, later complications, or reduced life expectancy (all of which we simply don't know enough to quantify well.)

The answer that health economists have to this question is the QALY, which has its own drawbacks. For example, QALYs can't uniformly measure the risks of Russian roulette, since the risk depends on the age and quality of life of the player.

What we're left with is that the actual question we want answered has a couple more dimensions than a single metric can capture - and as I have mentioned once or twice elsewhere, reductive. metrics. have various. problems.

I guess the actual real question is "Is there a good blogpost somewhere that 80/20s the overall question of 'what are some reasonable/least-bad-ways of quantifying risk, and gives a rough rundown of how various common activities compare'?"

It might be that another way of reframing the question is "Could someone write a LW style book review of the Norm Chronicles?" (looks like I should perhaps read it in full, but it'd still be useful to have the key takeaways summarized)


I'm pretty sure this chart has been posted here before in a similar context, but probably won't hurt reposting.

This actually looks pretty close to the thing I wanted, thanks!

This chart might be misleading in that it doesn't account for the impact of a person's skill on the danger. Some of these activities have a fixed risk (commercial flying), while others directly depend on how fit/agile/careful the person is, so the risk probably varies by orders of magnitude between individuals (motorcycling). At the more dangerous end, I'd expect the risk to be underestimated significantly: many people go skiing, only a few very fit people attempt to climb Everest.

There's not much to say about the post itself. It is a question. Some context is provided. Perhaps more could have been, but I think it's fine.

What I want to comment on is the fact that I see this as an incredibly important question. I would really love to see something like microCOVID Project, but for other risks. And I would pay a pretty good amount of money for access to it. At least $1,000. Probably more if I had to.

Why do I place such a high value on this question? Because IMO, death is very, very, very bad, and so it make sense to go to great lengths to avoid it. I argue extensively for that perspective in this post.

I get the sense that I'm 2+ standard deviations above the mean of the LW community in how strongly I feel about this. For people who don't think death is as bad as I think it is, maybe this post I am reviewing isn't that important. I'm not sure.
