We’ve been hacking at psychology for 200 years, without much progress. We can't cure depression, we don’t know why rats like running on wheels, and we don’t know why when you’re sick, sometimes you feel too hot and too cold at the same time.

Maybe we're doing it wrong. (🧵) Image
People have been doing psychology since the 1860s, but we're not much closer today than when we started. So what's holding us back?

We think the problem lies in just a few assumptions that people have been holding the whole time, totally unaware that they’re holding ‘em.Image
Image
Image
1⃣ The first assumption is that people are reward maximizers.

We usually assume that people find some things rewarding and try to get as much of those things as they can, with no limit.

Like cake. You always eat as much cake as you can, right? Because it's so rewarding.Image

There are lots of ways to die.

To avoid biting the dust, many things need to be juuuust right. If you get too hot or too cold, you die. If you don’t eat enough, you die. If you make too much blood, too little blood, if you [other thing], if you [third thing], dead dead dead. Image
It’s a miracle that organisms pull this off.

How do they do it? Easy: they make thermostats.

A thermostat is a simple control system.

Thermostats are designed to keep your house at a certain temperature. You don’t want the house to get much hotter than the target temperature, and you don’t want it to get much colder. Image

Time for a story about how when you heat things up, they almost always get bigger. Image
Take almost anything, heat it up, and it gets bigger. Heat it up enough, it melts and becomes a liquid. Heat it up even more, it becomes a gas, and takes up even more space. Or, cool it down, it contracts and becomes smaller again.

The year is 1789. Antoine Lavoisier has just published his Traité Élémentaire de Chimie — usually known as just Elements of Chemistry.

The very first thing Lavoisier talks about in his book is this mystery about heat.Image

For @threadapalooza — 100 tweets about 100 scientists (and closely-related philosophers and mathematicians) in approximately chronological order
(Inspired by @DefenderOfBasic learning about Mary Somerville:)

1. Hippocrates of Kos (c. 460 – 370 BC)

• Greek philosopher who invented medicine as a field
• possibly first to think that diseases were natural, not divine punishment
• famous for theory of humors
• in practice seemed to think that medicine mostly depended on what you ate Image

Let's say you're eating a twinkie. How much lithium is in that twinkie? How much lithium is in your food in general? Turns out this is harder to answer than you might think. Image
Lithium at clinical doses (50-300 mg/day) is a powerful sedative with lots of nasty side effects.

Many effects also show up for subclinical doses (1-50 mg/day), and even trace doses (< 1 mg/day) seem to have some effects.

So you might want to know how much is in your food. Image
There are lots of methods you can try.

This usually involves some kind of chemical liquefication (“digestion” in the parlance) paired with a tool for elemental analysis.

You need digestion because many analytical techniques can only be done on liquids. Image

Many years since we've done such an exemplary study.

That's right, the first potato diet analysis is out!

slimemoldtimemold.com/2022/07/12/los…
Do be warned that this post is about 25,000 words long, with many many figures and images. So if you have questions or comments, we strongly encourage you to read it and see if we address it in the post

That said, here's some topline results!
We first announced the Potato Diet Community Trial on April 29, 2022, which we described on twitter in this thread:
