It wasn’t just one person, it was a trend. Here are a bunch of other Roman shrimp rings

one of the best academic paper titles

for those who don't speak academia: "according to our MRI machine, dead fish can recognise human emotions. this suggests we probably should look at the results of our MRI machine a bit more carefully"

I hope everyone realises how incredibly important this dead fish study is. This was SO fucking important.

I still don’t understand

So basically, in the psych and social science fields, researchers would (I don't know if they still do this, I've been out of science for awhile) sling around MRIs like microbiolosts sling around metagenomic analyses. MRIs can measure a lot but people would use them to measure 'activity' in the brain which is like... it's basically the machine doing a fuckload of statistics on brain images of your blood vessels while you do or think about stuff. So you throw a dude in the machine and take a scan, then give him a piece of chocolate cake and throw him back in and the pleasure centres light up. Bam! Eating chocolate makes you happy, proven with MRI! Simple!

These tests get used for all kinds of stuff, and they get used by a lot of people who don't actually know what they're doing, how to interpret the data, or whether there's any real link between what they're measuring and what they're claiming. It's why you see shit going around like "men think of women as objects because when they look at a woman, the same part of their brain is active as when they look at a tool!" and "if you play Mozart for your baby for twenty minutes then their imagination improves, we imaged the brain to prove it!" and "we found where God is in the brain! Christians have more brain activity in this region than atheists!"

There are numerous problems with this kind of science, but the most pressing issue is the validity of the scans themselves. As I said, there's a fair bit of stats to turn an MRI image into 'brain activity', and then you do even more stats on that to get your results. Bennett et. al.'s work ran one of these sorts of experiments, with one difference -- they used a dead salmon instead of living human subjects. And they got positive results. The same sort of experiment, the same methodology, the same results that people were bandying about as positive results. According to the methodology in common use, dead salmon can distinguish human facial expressions. Meaning one of two things:

  • Dead salmon can recognise human facial expressions. OR
  • Everyone else's results are garbage also, none of you have data for any of this junk.

I cannot overstate just how many papers were completely fucking destroyed by this experiment. Entire careers of particularly lazy scientists were built on these sorts of experiments. A decent chunk of modern experimental neuropsychology was resting on it. Which shows that science is like everything else -- the best advances are motivated by spite.

I do love the phrase executive dysfunction bc the image it conjures is of a bunch of people wearing business suits around a long oval conference table  arguing with each other to the point where they’re getting into physical fights, but in the background there’s just a big empty whiteboard with a To Do list with one item on it and that item is “take shower”

“In 1404, King Taejong fell from his horse during a hunting expedition. Embarrassed, looking to his left and right, he commanded, “Do not let the historian find out about this.” To his disappointment, the historian accompanying the hunting party included these words in the annals, in addition to a description of the king’s fall.“

LMFAOOOOOO rip to that guy

i thought maybe this was fake, but there’s even a citation!

Taejong Sillok Book 7. 5th year of King Taejong’s Reign (1404), February 8.

Happy 618th anniversary of the day King Taejong fell from his horse!

Apparently the recorders were really intense about this. We have a record of King Taejong complaining about a recorder who followed him on a hunt in disguise and another who eavesdropped on him behind a screen. No one was allowed to see the records, even the king (one king did and killed five men based on what was written there, after which they took greater care to ensure it would never happen again), and changing the content or disclosing it was a capital punishment. Even when there were rival political factions trying to influence the writers, they wrote down what was a revision and what wasn’t and kept an original version with no revisions in it.

They also made sure to back up their data. They made four copies of it, then when three copies were lost in the Imrim Wars they decided to make five more copies just in case. One copy was destroyed in a rebellion, another was partially damaged in an invasion, and Japan stole one copy during their occupation and moved it to Tokyo University, where it was mostly destroyed in the Kanto Earthquake (47 books remained and were returned to South Korea in 2006). Now the whole thing is digitized, free on the internet, and translated into modern Korean for all to see.

It took centuries of meticulous recorders, justifiably paranoid copiers, absolutely determined historians, and painstaking infrastructure for this joke to be possible. Happy 618th anniversary to the day King Taejong fell from his horse.

Happy 619th anniversary to the day King Taejong fell from his horse!
