I was typing an entire post about food issues and why I don’t like wet food, until I remembered that unlike in Dutch, ‘wet food’ has a specific meaning in English. Just straight up deleted everything bc all I could see myself as was
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.
The sentence “you can’t be talking like that, white baby” has permanently ruined my relationship with my cats bc I can’t stop saying it any time one them meows at me.
“Oh boo hoo you shouldn’t ask your friends for favors we’re all adults”
I just spent three hours pulling up carpet and staples for a friend’s home renovation and we all did nothing but chat and joke and have wonderful conversation the whole time.
Helping somebody move or renovate or giving them a ride to the airport is functionally the same as going mini-golfing or playing a board game: it’s an activity that you do that is made more fun by having good company, and which provides something to talk about when the conversation lulls.
