Scientists have always had a thing for Middle Earth. It has been the subject of many published academic journal articles, as well as some great analyses by scientists from their disciplines. Here are some good ones, the more elaborate the better... 1/n theatlantic.com/health/archive…
Let’s start with geology, and geologist & science fiction author @katsudonburi’s issues with Tolkien’s mountain ranges (written before plate tectonics was a known thing) 2/n tor.com/2017/08/01/tol…
And then there is this terrific map of the rocks of Middle Earth by a cosmogeologist 3/n
And this six-part tour of the geology & vulcanology of Lonely Mountain that explains why there is so much gold there, among other things. 4/n pascals-puppy.blogspot.com/2013/12/unnatu… ImageImage
Turning to military history, here is historian @BretDevereaux’s six-part discussion of the Siege of Gondor from the perspective of pre-gunpowder warfare. 5/n acoup.blog/2019/05/10/col…
Here’s archaeology, with @AlmostArch looking at the material culture and ruins of Middle Earth. 6/n almostarchaeology.com/post/105051279…
And of course Tolkien was a professor of Anglo-Saxon & English literature who made up languages, but this post on the true names of the main characters of the Lord of the Rings (it isn’t what you think) revealed a lot of the cleverness of the author. 7 amethystmarietm.tumblr.com/post/185331460… ImageImage

People spend 15% of work in meetings (managers spend 50%!) & post-COVID meetings are up 14%. But we spend little time trying to make meetings better, despite the fact that there is a whole subfield of research on the topic! Here is a review of findings. researchgate.net/publication/32… ImageImageImage
Here’s the highlights as emoji:

Before the meeting...
✅only meet if needed
🐁keep meeting sizes as small as possible
🎯set clear goals & outcomes
📄have an agenda that all review in advance
⏰make it short & relevant to all invited 2/4
During the meeting...
⏱arrive on time
📋follow the agenda
🙋‍♀️🙋‍♂️everyone participates
💻📱never multitask
⚔️intervene if mood turns negative
🤪humor helps performance
🙅‍♀️leave time for objections
🗳Let everyone help decision-making. If a decision is made, tell everyone

A great example of borrowing innovation from one field for another. Doctors at a struggling children's hospital sent videos of their post-surgical hand-offs to Ferrari's F1 pit crew (see the GIF!) to improve. They reworked the process & reduced associated errors rates by 66%. 1/2
The diagrams show how the F1 crews used their techniques to help the surgery teams reorganize the surgery to ICU handoff. The paper is here: 2/2 asq.org/healthcare-use… ImageImage
The Youtube video for the original GIF of the Ferrari F1 pit crew is here, and it is worth watching it (or the GIF) multiple times, each time focusing on a different person doing their job with incredible speed and precision.

Does it make the Mafia seem more or less cool when you know that it was created to control the market for lemons? After the discovery of citrus as a cure for scurvy there demand for Sicilian 🍋 went crazy. The Mafia was formed in response to a commodity boom to keep prices high.
The paper is here: cambridge.org/core/services/…

And, in the great tradition of economics papers, the title is a bit of an inside joke, referring to a very famous economics paper about the market for (metaphorical) lemons.

Psychology experiments need to be able to get people to react emotionally very quickly. How do they do it? Movie clips! These are the scientifically vetted clips historically used to elicit emotion.

For fear 😱 the choice is pretty obvious. 1/4
For anger 😡, either the police abuse scene from Cry Freedom (the clip isn’t online) or else this scene from The Bodyguard 2/4
For sadness 😭 this scene from The Champ even beats the death of Bambi’s mother. 3/4

How some sociologists think games might have stopped a Marxist revolution: a thread.

When people are bored at work, they play games. There is graffiti in the Pyramids suggesting that work was done on teams with names like "Drunkards of Menkaure," competing for extra beer. 1/n Image
In the grind of early 20th century factories, sociologists working undercover found games everywhere. See this passage from the famous "Banana Time" (the paper is a great read, since it is clear that the other workers were mocking Roy, who didn't get it) 2 faculty.knox.edu/fmcandre/roy-b… Image
Another undercover sociologist, Burawoy (working at the same factory as Roy, many years later), noticed something interesting: though games were seen as a time waster and act of rebellion by workers, they were often secretly tolerated by bosses. Why? 3/n Image

Previous studies suggested that teaching kids chess improved a whole lot of outcomes, from math skills to logic to academic achievement.... except that almost all of these studies were small. A large randomized trial with 4,000 students finds no advantages to learning chess 1/2
The findings are interesting in itself (I don't have to feel guilty about not teaching my kids chess!), but it also has a bigger point: small samples sizes (and the file drawer problem where null results aren't published) result in accidental bias. 2/2 muse-jhu-edu.proxy.library.upenn.edu/article/706374…
Also, playing an instrument also has no effect on cognitive development (though music is nice for its own sake!)
