Cockatoo Culture

Even when residents in these areas weigh down the tops of their bins with bricks or stones, cockatoos have figured out how to knock these heavy objects to the ground. Once that barrier is removed, the hungry birds can crack the lid open with their beak, prop it on their heads and walk it back until it fully flips on its hinges, as the videos show below. This unique skill has now become so widespread in Sydney, researchers think the parrots are imitating and learning from one another – a sign of cultural evolution.

The Ideal University

The people who write and grade the students’ tests would not be their instructors. Students would have to acquire a genuine general knowledge base, not just memorize what is supposed to be on the exam. It would not have assistant deans, student affairs staff or sports teams. The focus would be on paying more money to the better instructors. Instructors would not have tenure, but would have to compete for students — by offering them classes and services that would help them graduate and improve the quality of their certification pages. The school would hire online instructors too, many of them from poorer countries and working at lower wages. None of the instructors would be required to have any undergraduate or advanced degrees.

2021-11-09: Tyler is involved in a new university:

To the historian’s eyes, there is something unpleasantly familiar about the patterns of behavior that have, in a matter of a few years, become normal on many campuses. The chanting of slogans. The brandishing of placards. The letters informing on colleagues and classmates. The denunciations of professors to the authorities. The lack of due process. The cancelations. The rehabilitations following abject confessions. The officiousness of unaccountable bureaucrats. Any student of the totalitarian regimes of the mid-20th century recognizes all this with astonishment. It turns out that it can happen in a free society, too, if institutions and individuals who claim to be liberal choose to behave in an entirely illiberal fashion.

Tetris revolution

The improvements have added up. To qualify for the 2020 C.T.W.C., players had to achieve a near max-out within 2 hours. This standard of play left behind veterans who had qualified in each of the previous 10 years. Jonas, with his 1 max-out in qualification, entered the tournament ranked 31th among 64. Joseph, having scored a world-record 12 max-outs, came in as the No. 1 seed. By the quarter-final, the entire old guard had vanished. The remaining players were all of the YouTube generation, with many explicitly crediting its algorithm for introducing them to classic Tetris.

Hybrid forever

Really remote school should continue, partially, forever

global classrooms could be tailored so every student is at a similar level, ready to be challenged and learn well from the material provided. If it’s judged a student is having too much trouble in a class, or to little, it’s very simple to switch them until they find just the right level.

Intellectual Progress

the single most important thing I discovered this decade (due to a random comment in the SSC subreddit!) was the predictive coding theory of the brain. I started groping towards it (without knowing what I was looking for) in Mysticism And Pattern-Matching, reported the exact moment when I found it in It’s Bayes All The Way Up, and finally got a decent understanding of it after reading Surfing Uncertainty. At the same time, thanks to some other helpful tips from other rationalists, I discovered Behavior: The Control Of Perception, and with some help from Vaniver and a few other people was able to realize how these 2 overarching theories were basically the same. Discovering this area of research may be the best thing that happened to me the second half of this decade (sorry, everyone I dated, you were pretty good too).

Psychedelics are clearly interesting, and everyone else had already covered all the interesting pro-psychedelic arguments, so I wrote about some of my misgivings in my 2016 Why Were Early Psychedelicists So Weird?. The next step was trying to fit in an understanding of HPPD, which started with near-total bafflement. Predictive processing proved helpful here too, and my biggest update of the decade on psychedelics came with Friston and Carhart-Harris’ Relaxed Beliefs Under Psychedelics And The Anarchic Brain, which I tried to process further here. This didn’t directly improve my understanding of HPPD specifically, but just by talking about it a lot I got a subtler picture where lots of people have odd visual artifacts and psychedelics can cause slightly more (very rarely, significantly more) visual artifacts. I started the decade thinking that “psychedelic insight” was probably fake, and ended it believing that it is probably real, but I still don’t feel like I have a good sense of the potential risks.

In mental health, the field I am supposed to be an expert on, I spent a long time throwing out all kinds of random ideas and seeing what stuck – Boorsboom et al’s idea of Mental Disorders As Networks, The Synapse Hypothesis of depression, etc. Although I still think we can learn something from models like those, right now my best model is the one in Symptom, Condition, Cause, which kind of sidesteps some of those problems. Again, learning about predictive processing helped here, and by the end of the decade I was able to say actually useful things that explained some features of psychiatric conditions, like in Treat The Prodrome. Friston On Computational Mood might also be in this category, I’m still waiting for more evidence one way or the other.

AI applied to Education

The future of online education is adaptive assessment, not for testing, but for learning. Incorrect answers are not random but betray specific assumptions and patterns of thought. Analysis of answers, therefore, can be used to guide students to exactly that lecture that needs to be reviewed and understood to achieve mastery of the material. Computer-adaptive testing will thus become computer-adaptive learning.
