I did fake Bayesian math with some plausible numbers, and found that if I started out believing there was a 20% per decade chance of a lab leak pandemic, then if COVID was proven to be a lab leak, I should update to 27.5%, and if COVID was proven not to be a lab leak, I should stay around 19-20%

This is so confusing: why bother doing "fake" math? How does he justify these numbers? Let's look at the footnote:

Assume that before COVID, you were considering two theories:

  1. Lab Leaks Common: There is a 33% chance of a lab-leak-caused pandemic per decade.
  2. Lab Leaks Rare: There is a 10% chance of a lab-leak-caused pandemic per decade.

And suppose before COVID you were 50-50 about which of these were true. If your first decade of observations includes a lab-leak-caused pandemic, you should update your probability over theories to 76-24, which changes your overall probability of pandemic per decade from 21% to 27.5%.

Oh, he doesn't, he just made the numbers up! "I don't have actual evidence to support my claims, so I'll just make up data and call myself a 'good Bayesian' to look smart." Seriously, how could a reasonable person have been expected to be concerned about lab leaks before COVID? It simply wasn't something in the public consciousness. This looks like some serious hindsight bias to me.

I don’t entirely accept this argument - I think whether or not it was a lab leak matters in order to convince stupid people, who don’t know how to use probabilities and don’t believe anything can go wrong until it’s gone wrong before. But in a world without stupid people, no, it wouldn’t matter.

Ah, no need to make the numbers make sense, because stupid people wouldn't understand the argument anyway. Quite literally: "To be fair, you have to have a really high IQ to understand my shitty blog posts. The Bayesian math is is extremely subtle..." And, convince stupid people of what, exactly? He doesn't say, so what was the point of all the fake probabilities? What a prick.

Scott is saying essentially that "one data point doesn't influence the data as a whole that much" (usually true)... "so therefore you don't need to change your opinions when something happens" which is just so profoundly stupid. Just so wrong on so many levels. It's not even correct Bayesianism!

(if it happens twice in a row, yeah, that’s weird, I would update some stuff)

???????? Motherfucker have you heard of the paradox of the heap? What about all that other shit you just said?

What is this really about, Scott???

Do I sound defensive about this? I’m not. This next one is defensive. [line break] I’m part of the effective altruist movement.

OH ok. I see now. I mean I've always seen, really, that you and your friends work really hard to come up with ad hoc mental models to excuse every bit of wrongdoing that pops up in any of the communities you're in.

You definitely don’t get this virtue by updating maximally hard in response to a single case of things going wrong. [...] The solution is not to update much on single events, even if those events are really big deals.

Again, this isn't correct Bayesian updating. The formula is the formula. Biasing against recency is not in it. And that's just within Bayesian reasoning!

In a perfect world, people would predict distributions beforehand, update a few percent on a dramatic event, but otherwise continue pursuing the policy they had agreed upon long before.

YEAH BECAUSE IT'S A PERFECT WORLD YOU DINGUS.

Complete sidenote, but I hate how effective altruism has gone from "charities should spend more money on their charity and not on executive bonusses, here are the ones that don't actually help anyone" to "I believe I will save infinity humans by colonizing mars, so you can just starve to death today".

[-] swlabr@awful.systems 13 points 10 months ago

I suspect a large portion of people in EA leadership were already on the latter train and posturing as the former. The former is actually kinda problematic in its own way! If a problem was solvable purely by throwing money at it, then what is the need for a charity at all?

@swlabr @Tar_alcaran

Well, because (most) governments (mostly) *don't* throw money at the problems that *could* be solved by throwing money at them.

Look at the malaria prevention or guinea worm eradication programs, for instance. Ten years ago or so, my first encounter with EA was a website talking about how many lives you could save or improve by giving money to NGOs focused on those issues.

Hell, look at homelessness in most "Western" countries, except Finland. Look at UBI. etc.

[-] swlabr@awful.systems 6 points 10 months ago

Ok, so to be clear, I would (perhaps naively) prefer it if we didn't have charities/NGOs and that governments would handle solving problems and helping people entirely. Of course, this is reductive; there are probably plenty of spaces where NGOs and charities are better suited for approaching some issues.

That being said, while money (or a lack thereof) is the main issue in solving many problems, you still need all kinds of work to make it effective. In the case of malaria prevention, a cause EA deems to be cost-effective, you still need to pay staff to carry out logistics to deliver whatever nets or vaccines you buy with money. You wouldn't want someone incompetent at the helm; that could cause your cost-effectiveness to go down. And how do you incentivize competent people to stay in leadership positions? There are plenty of ways, but executive bonuses will be at the top of that list.

Anyway, my main issue with EA has gotta be how it launders false morality and money into morality. The false morality is the X-risk shit. The money is the money from working in tech.

@swlabr

Oh I'm in total agreement with you on all these points.

I really detest the bizarre self-delusional stuff that masquerades as "Altruism" for the TREACLES people. (Yes that's a deliberate mis-acronyming.)

What I was trying to express, but not clearly enough, was that I'd really like someone to help with working out what's a genuinely effective use of effort and/or money. It's doubly frustrating that the people who looked like they might be trying to do that were just a crank AI cult.

Hurling ordure at the TREACLES, especially those closely related to LessWrong.

AI-Industrial-Complex grift is fine as long as it sufficiently relates to the AI doom from the TREACLES. (Though TechTakes may be more suitable.)

This is sneer club, not debate club. Unless it's amusing debate.

[Especially don't debate the race scientists, if any sneak in - we ban and delete them as unsuitable for the server.]
