What are some sensible-sounding alternatives to eliminating the snitch entirely?

The best I can think of is have two snitches—red snitch, blue snitch. Whenever a seeker catches their snitch, the opposing team can't score any more; the game ends when the second snitch is caught.

Fantastic, I wish I'd had this back when almost everyone in LW/EA circles I met was reading the biography of everyone in the ' fortune 400 and trying to spot the common factors. A surprisingly common strategy that's likely not to work for exactly these reasons.

Well, there's a correlation between race and height, too, no doubt, but such correlation is utterly insignificant comparing to variance within either race - you don't say whites are taller or blacks are taller, there's very short black populations and very tall ones, and ditto for the whites whose variance is smaller.

The quantitative differences make a qualitative difference here.

Racists believe the correlation to be of greater significance than that of correlation between the height and intelligence. Based on fairly poor evidence - Raven's matrices are not this culture fair, they're culture fair in the sense that you can test British, Germans, French, Russian, and Chinese and Japanese with it, not in the sense that you can go and test some tribe that doesn't do much arithmetic nor is exposed to similar visual stimuli.

By the way given the diversity of blacks it would be utterly surprising if there is not a single ethnicity there with an average IQ greater than 100, as well as IQ with greater or smaller variance. (I would expect blacks to have larger variance than whites because they're plain more diverse, and mixed to have greater variance still)

Then the "rational" racists also object to use or even the existence of correlation between such racism and intelligence, conscientiousness, education, and other factors.

First, I want to say this: I have no idea whether his claim that Africans got a lower IQ score on the test in question is true or false. I hope it is false. There's a possible explanation that is totally in support of the Africans, EVEN if the claim was true. Here it is:

IQ tests are culturally biased. If the test asks "How do you use a teacup?" a British person will be likely to know the answer - a lot of them use teacups daily. Do Africans use teacups every day? Maybe they'll bomb on the teacup question because they drink their tea from bowls as with Japanese matcha tea, or from gourds as with yerba mate tea. If you ask them "Is a rattlesnake dangerous?" that question is irrelevant to them. They have boa constrictors, but not rattlesnakes.

There are tests that are designed to prevent these differences from influencing your score. They're called "culture fair tests". Nobody here has specified whether a culture fair test was used (I searched the page).

The chapter itself provides the translation in the line immediately following: "Three shall be Peverell's sons and three their devices by which Death shall be defeated."

Þregen béon Pefearles suna and þrie hira tól þissum Déað béo gewunen.

Harry perhaps now recognizes himself not as an originator of a plot against Death, but as an intermediate result of that plot.

The primary source of the post was an extensive email exchange with Adam Casey (currently working full time at CEA). Since we are friends, this was not primarily in an official capacity. I also asked Adam to cross check the numbers whilst wearing a more official hat.

I was encouraged by him and Alexey Morgunov (Cambridge LWer) to make the substance of this public immediately after Will Crouch came up to Cambridge.

This is plausible. As someone who experiences pain as suffering, I need to cultivate the skill of doing painful things when I consciously decide that they should be done. If I had pain asymbolia, I imagine I'd need to instead cultivate the habit of making conservative decisions about my long-term health.

I am amazed you were able to make as much sense of it as you were! Thank you for posting this!

I've fulfilled my first promise: AD/BC problem. I have punted on the second; I've supplied contact details, but someone who is actually going to be at the meetup will have to invite Styles to speak.
