As a response to the rightwing, some academics are pushing for a world where scientists are above social criticism.

Critiquing the motivations and behaviors of scientists isn't anti-science. It's democracy.

A thread.
I frequently see academics imply it's morally wrong or anti-science to tweet negative things about them and their field. This is somewhat understandable. Who wouldn't want to live in a world where it was morally wrong to criticize us and our work?
I guess it's possible a mean tweet could hurt a field's reputation but so what? Tweeting mean things about Pepsi could cause Pepsi to be less popular and Pepsi employees to lose their jobs. That doesn't mean tweeting mean stuff about Pepsi is morally wrong.
Are academic fields really so fragile that one bad tweet could cause the whole thing to come crashing down and thousands of scientists to lose their jobs?
To be clear, I agree that it's good to promote being on the same page about scientific *facts* BUT this is different from implying it's somehow out of bounds to have opinions about scientists as human beings and their communities.
I know many people are sensitive around issues of stereotyping and speech harm but not all categories are equal. In my opinion, it's fine to tweet "California sucks" or "Guys on tinder are the worst". This kind of talk is just a normal part of human societies.
In the specific case of protected categories like race, humans have a long history of horrific atrocities resulting from our tendency to stereotype. It's a *special* case that requires *extra* safeguards. Trashing IQ researchers, for instance, is not the same thing at all.
Also, I think a lot of academics on Twitter are abusing the language of science education to win arguments. They often claim to be "correcting misconceptions" which invokes the framework of *factual* errors when they're really just pushing back on *criticisms* they don't like.
Let me boil it down. Correcting folks on how gravity works is science education. Claiming someone is "spreading misconceptions" if they don't agree that physicists are hard-working, kind-hearted souls who just want to make the world better is not. That's doing PR for your field.
My message to academic Twitter is simple. Don't act like mean tweets about your academic field are oppression. Don't use your PhD as a cudgel to stamp out opinions about your field that you don't like. Stuff like that will probably backfire. Badly.
This kind of long-form content takes extra work so if you like it and want to show support, like and retweet the thread, and give me a follow! 🙂

Every time I see Claire Lehmann on my timeline, she’s all over the map. Here she is going out of her way to threaten an academic epidemiologist with legal action during a pandemic in defense of racist comments by Lindsay (who isn’t even named in the Tweet).
Ten months later she’s denouncing the same Lindsay for his racism
One month later she’s saying stuff like this

Folks have been bashing this mentorship program because of Google’s recent track record of what some might call “anti-blackness” but it doesn’t seem like most folks read the materials. I did and I have concerns. 🧵👇🏾
Look at this. They say they will “desk reject”, as in not even READ your application, if it’s not max 2 pages, 8.5” by 11”, Times New Roman font, 1” margins, single spaced, in PDF format. This is more stringent than a grad school application and probably quite a few term papers.
What else will they desk reject for? Including your contact information. That’s right. They will not even consider your application if it has your name in it.

Folks seem to think that Charles Murray's arguments are just about the black-white IQ gap being genetic. They're not. The gap in IQ between receptionists and doctors is much bigger than the black-white IQ gap. His arguments imply that's genetic too!
His views imply that if you choose 1000 doctors and 1000 receptionists at random and analyze them genetically, you will find systematic genetic differences between both groups and these genetic differences hugely pre-determined their cognitive abilities and life outcomes.
Murray's arguments don't just imply that blacks are genetically limited (on average). They imply that if you or someone you know didn't do well on the SAT for instance then more likely than not, it's largely because of genetically pre-determined cognitive limitations.

In my opinion, this plot represents one of the MOST important facts about American society today. The white population has a huge extra hump of older people that other demographics don't have.
I think that hump could explain why there's so much fear around how America is "changing". The younger generation is more mixed so the normal intergenerational conflict is perhaps being magnified by the fact that the younger generation doesn't "look like" the older generation.
I suspect age contributes to racial differences in politics in two ways. The first is obvious. Young people have different wants and needs from older people. So it matters that whites are proportionally so much older.

"The cognitive demands of those jobs mean a lot more white people qualify than black people."

This video is full of misuses of statistics! A thread. 🧵👇

1. First of all. CORRELATION IS NOT CAUSATION. As a statistician, I'm contractually obligated to let you know that these patterns that he's talking about are all correlations. They are not proof of causation.
2. An IQ difference of 12 points is NOT "a lot". The distribution of IQ and the distribution of human height are very similar. They follow what's called a bell curve. So, we can get an intuition for IQs by thinking about heights which we are typically more familiar with.

IQ often gets used to promote racism on the internet but it's also highly mathematical so people don't really understand it.

In this thread, I will explain:

1. How the math of IQ works at a high level (don't worry no formulas!)

2. Why IQ is partly socially construct... 🧵👇
An IQ test is basically a list of questions that a psychometrician (kind of a cross between a psychologist and a statistician) thinks might measure intelligence. If you give such a test to a lot of people, you will get a range of scores.
The first thing you might notice is that the distribution of scores isn't a nice shape. So psychometricians adjust the scores so that a certain number fall within certain percentiles so you get a nice bell curve like this:
