The central claim in the biological race discussion is that "two people of the same race are more genetically alike than either are to a person of a different race".

This has been categorically falsified scientifically.
What often frustrates is that bio race realists will make claims based on this assumption, but then they refuse to stand by or defend it.

The smarter ones among them at least know their belief doesn't hold up to what's now known about genetics.
So one thing I want to see from bio race realists is a definition of race that is objective and independent of races they already believe to exist (i.e don't start by begging the question).

Present a method that can objectively construct what they believe to be bio races.
Since I posted this a lot of the responses has been that the key feature is in differences in gene variant frequencies.

That's the claim they only defend when one begins by embracing their assumption that race is real.

Just the worst approach to science.
From a statistical perspective, the more precise version of my initial quote is that the concept of biological race being valid requires that there is less genetic variation within a race than between races.

Bio race realists reason on this assumption, but refuse to defend it.

A diagram like this helps to explain why race isn't biologically real.

Let's do a thread Human genetic diversity categorized by continent, with non-A
So humans are 99.9% the same genetically. In this diagram, the SNPs (think of them as places where people differ) that are known are grouped by the locations of people who carry them.

What we can see is that almost all of humanity's genetic diversity is found within Africa 2/ Human genetic diversity categorized by continent, with non-A
Those in Europe and those in Asia contain almost a subset of the genetic diversity found in Africa.

This is the same sort of pattern you'd see if Africa was again split into Nigeria and not-Nigeria.

So those outside Africa are like smaller groups within Africa. 3/

GDPR isn't even that brutal in terms of data regulations. It makes you wonder what American companies are collecting that makes it so hard for them to be compliant.
GDPR basically says data that is personally identifiable (can be used to say who you are in real life) belongs to you.

Companies must have your consent or legal justification to use or transfer your personal data. You can withdraw that consent at any time.
GDPR also includes some guidelines for how companies can implement these regulations.

Here's the thing: GDPR is fairly easy to implement for a company that actually cares about data privacy. You want to work with those companies anyway.

I'm assuming other Arsenal fans are considering this game against Man City a write-off.

Let's just have some fun then.
Gunners, I dare not dream...
This is why I don't dream.

What's often labeled culture is simply rational behaviors given a people's environment.
One of the reasons I often criticize the "culture" explanation for disparate racial outcomes is that it's built on the assumption that some "races" behave more irrationally compared to others within the same environment.
An assumption of cognitive inferiority in terms of decision making and behaviors in my mind can't be separated from the view that there is something inherently wrong with those "races" relative to others.

This is a fantastic article on math education.

A thread with some of my thoughts.

First, America ranks 31st out of 79 more advanced countries. Not great. America ranks 31st out of 79 advanced countries in terms of
Pretty cool that Estonia is the top performing European country and it doesn't put a massive emphasis on standardized tests with consequences.

I think those tests often tend to create perverse incentives for politicians, teachers and students.

My son and I made a Python script to measure Twitter readability scores using the Flesch reading-ease test (higher means more accessible language)

Some folks on here:

Noah Smith: 83.8
Mansa: 78.5
Rod Graham: 74.315
ShimminyKricket: 73.88
Wes Yang: 65.7
Conor: 63.23
Some more folks

Kareem: 72.78
Katja: 72.5
Deonteleologist: 68.2
Epoe: 67
Matt Yglesias: 63.6
May end up putting this on a webserver somewhere. It gives multiple readability scores.

If someone has a webserver and wants to host, would be happy to give the code.
