"But people jumping from nucleotide polymorphisms to grand social policy (that just happens to echo a century's worth of rightly-discredited eugenics advocacy) deserve the scepticism they get in my view."

If so, what is the 'grand social policy' that Cofnas advocates or has advocated?

As far as I can tell from the paper, the only thign that seems like a policy proposal is that educational programs should be tailored to different ability profiles (and what he said about Head Start). But him saying that maybe we should fund different educational interventions isn't eugenics, or abouyt treating individuals differently depending on their race/ancestry. The paper argues against using group differences to blame or rank anyone. (See section 5.2 as it's the main point there.)

The overlapping-distributions point makes sense: even if group differences turned out to be partly genetic, group mean/median IQ or whatever isn't a good proxy for individuals from that group. So if you have a policy that is based on group membership (not individual assessment), it's going to be poorly targeted and end up wasting resources.

Section 4 endorses 'tailored' programs and doesn't explain how they'll be targeted. He doesn't say they'd be targeted by group membership, though. He references Jensen 1969 (https://gwern.net/doc/iq/1969-jensen.pdf) and in that paper Jensen advocated individual testing, not assignment based on race/ancestry. From page 78:

  The important distinction between the individual and the population must always be kept clearly in mind in any discussion of racial differences in mental abilities or any other behavioral characteristics. Whenever we select a person for some special educational purpose, whether for special instruction in a grade-school class for children with learning problems, or for a "gifted" class with an advanced curriculum, or for college attendance, or for admission to graduate training or a professional school, we are selecting an individual, and we are selecting him and dealing with him as an individual for reasons of his individuality.

I do not believe Cofnas is racist or that his exposure of Arday was motivated by racial animus.

But, even if it were, he still did a service to the public by exposing the governance failures at Cambridge.

It has a removable battery so it seems the mechanism is designed to be left on the bike.

"Would they have to immediately move their HQ and fire all New York based employees?"

This is inconsistent with your statement "It seems New York is not attempting to have any say over what Kalshi does outside of New York, when it does not involve New York residents."

"The claim they are trying to prevent them from offering all event contracts nationwide is simply false."

If you use the public version of ntfy.sh then you don't need to do anything to set this up. If you self-host, you need your own Firebase Cloud Messaging (FCM) account and (for iOS) your own Apple Developer account so you can use APN.

- 11 GCSE grades

- 4 A level grades

- 1 University degree

For virtually all of these, the grades/results were determined by exams taken at the end of a period of study:

- GCSE exams taken at ~16yo

- A level exams taken at ~18yo

- University finals taken at ~21yo

At the time, I thought it was very very strange that my GCSE grades for English Language and English Literature were not based on exams, but on a bunch of essays I had written over a two year period.

It seemed strange because those past essays did not measure my current capability, but something else.

But this (measuring students on performance over multiple years) is the norm here in the US. Sure, many students take the SAT or ACT or various AP exams. But many students enter university with their academic performance measured on their high school GPA, which seemingly doesn't even attempt to measure mastery.

I installed it on an iPad Air (M2). On launch, I am given two options:

- Get started (primary CTA). Tapping this takes me to a blank screen.

- Sign in (secondary CTA). Tapping this and choosing 'Continue with email' gives me a login screen. I tried entering my email and choosing a password but it says "Couldn't find your account"

When you say 'pursue greater equality' do you mean we should keep making the tax system more progressive until everyone's after tax income is equal? If not, what should the shape of the curve be?

I'm mostly interested in economic growth, so looked at what the paper claimed about that.

It found that major, sudden reductions in taxes on the rich did not have any statistically significant effect on the trajectory of economic growth over the following five years.

But:

- Their sample is small. They only looked at relatively large, discrete declines in their home-grown measure of taxes on the rich. They did not look at all tax-rate changes.

- They did not look at effects beyond the five-year horizon, which means it would probably exclude the impact on people starting startups, as the successful ones usually take more than 5 years to start making serious money. (or did during the period the paper considered, even if timelines have subsequently accelerated.)

- Big sudden tax cuts don't happen in a vacuum, and I don't see a way to control for confounding.
