I'm interested in keeping an eye on AI. By a stroke of luck my PhD advisor is Laurence Aitchison.

3. Becoming less well-rounded
My background is extremely mixed: a lot of philosophy, a bit of economics, a bit of stats, a bit of computer science, a bit of computational linguistics, a bit of epidemiology, a bit of literary criticism. But in research, much depends on you mastering one thing or one cluster of things.
So I am trying to become less rounded. This boils down to more maths. One carrot: I aim to fully understand the great explanations: relativity, QM, evolutionary dynamics, Bayes, reinforcement learning, and computational complexity.

4. Giving a damn
I started teaching and mentoring at last. I head a camp at ESPR. I'm an external coach for 80,000 Hours. I speak for the dead.
Change my mind
I offer bounties for errors:
- $1 for nitpicks (ambiguities, misreadings, exceptions, technicalities).
- $10 for an error which falsifies a sentence.
- $50 for an error which invalidates a post.
Payouts
Page | Error | Person | Payout |
---|---|---|---|
About | Was unclear about the required size of error for a bounty, leading to a prima facie contradiction. | Loki Sempere | $10 to EA Funds |
/psych | Overstated the consensus against Milgram. It's still shaky, and not really about obedience, but it's wrong to say there's no evidence, just that the original experiments were terrible. | Matt Edwards | $5 |
/gists | I said "constant time" instead of "constant time complexity". The function in question takes 3x more time to process 2^64 than it does 2^0, hence the intermediate payout between nitpick and falsehood. | Loki Sempere | $5 |
Bets
Bet | Bettor | Odds | Resolution |
---|---|---|---|
Jun 2022: Everything Everywhere All at Once to win no Oscars besides Visual Editing. (0-1 Oscars overall) | CR | 1:1, nice dinner | To CR! |
July 2021: Abaluck RCT shows >15% reduction in covid transmission. | MH | 1:1, $100 to Givewell | To me. |
June 2020: Biden wins election. | CR | 1:1. Nice restaurant dinner. | To me. |
Jan 2016: Trump finishes term. | CR | 1:1. Nice bottle of whisky. | To me. |
Small print
I suppose this should all be multiplied by the confidence level of the post. Factual and logical errors are most likely to resolve cleanly; I probably won't cough up if you just tell me I'm an idiot for believing or not believing in e.g. Meinongianism. That would get a smile.
I'm not sure how to handle claims that have changed truth-value since I made them; half of this blog might be false if you return in 30 years. Leaning towards $1 to $5.

Books
I find that I've written two books: this site, and some book reviews.
I try to review every book I read, because otherwise within 4 years I will have forgotten absolutely everything about it, making a mockery of my use of my time on this earth; because giving a novel, fair, and readable opinion is the best and most complete mental exercise; because it changes the way I read, knowing that I actually have to form a real view; and because it leverages my vanity for great ends (I wished to be known as someone who reads a lot).
Most book reviews are vacuous, blocklike expressions of approval or disapproval. There is nothing in them except the reviewer, their squeals. I do some of those, but I try to do some of the other kind too.

It is equally fatal to the spirit to have a system and to not have one.
So you must combine the two. 1

...there is in men and women a motivation stronger even than love or hatred or fear. It is that of being interested โ in a body of knowledge, in a problem, in a hobby, in tomorrowโs newspaper.

Site
I love making this site better. I'm no designer but I enjoy the result. Here's a list of my design decisions.
The title alludes to Iain Banks: his powerful protagonists tease pompous people by taking names with as little gravitas as possible. To take the arg min of something is to find the thing which results in its lowest value.

Financial:
Political: Few. Never a member of any party.
- I am funded by UKRI and so really by the British government.
- I won an Emergent Ventures grant via Tyler Cowen.
- I own half of Arb Research which has dozens of clients.
- ex: I received a small EA Infrastructure Fund grant to try and fix executive function (โOff Roadโ).
- ex: Until 2019 I worked at AXA, a big insurer.
- ex: My 2021 mask paper used compute donated by Microsoft.
Political: Few. Never a member of any party.
Giving

I am cause-neutral (I'll support whatever is best, to the extent that objective evaluation is possible) and cause-sceptical (we don't really know what the best thing to do is).

DQ: A very nice website - links to the original papers, including participant numbers and number of citations... effect sizes and replications effect sizes.- Dan Quintana & James Heathers
JH: Very interesting, for a variety of reasons - and not just because it's fun to trawl through the wreckage... of 'those silly social scientists'. This [post] is a big old thing... much more comprehensive than anything I ever did... Not a lot of people would have the commitment to even try and organise something like this... You do get a sense of the enormity of [the replication crisis] which isn't really available through other documents...
DQ: What are the implications for how we actually teach first year psych?
JH: TEACH THEM THIS!
The best mask-wearing study so far?- Tyler Cowen
This was a great [conference]. I love how excited everyone was, like this guy. (If you're in the audience, sorry Gavin, didn't get your permission [to show that photo]).โ Will MacAskill
Utterly charming. In the nature of such lists, one does not expect to agree with every, single one---of course not. But the lists exhibit a lively and critical mind, unwilling to follow the usual party lines.โ Deirdre McCloskey 6
I'm honoured to be on your list [of favourite books].โ Robin Hanson 7
Nice image, young man. You may be a writer.โ Will Self 8
Also, my mum says I'm cool.
Identity
I try not to identify as things. My premises, projects and preferences say overwhelmingly more about me than my social identity does.
Tone
I'm sometimes told I'm too strident. I'll accept this, because constant hedging is unreadable, more annoying than authoritativeness. Also because strong claims galvanise opposition: as long as they're reasonable as well as strong, hopefully this stimulus creates value.
Anyway I'm not as sure as I sound: there's a comment box under every piece, call me out.

Why so many quotations?
Well, they're the densest store of insight. We are not empiricists by nature or by culture, so they are my concession to the apeish narrative side of mind. That quotes page is like a message digest of 10 years of me reading and learning.
I sometimes regret my instinctual distrust of Twitter: a lot of contemporary aphorists must be whiling away the years on there.

Metrics
Here are scales for rating all kinds of things.
Loss function
Above all I hope to beat the trend spotted by Robin Hanson about independent scholars:
over time amateurs blow their lead by focusing less and relying on easier, more direct methods. They rely more on informal conversation as analysis method, they prefer personal connections over open competitions in choosing people, and they rely more on a perceived consensus among a smaller group of fellow enthusiasts. As a result, their contributions just donโt appeal as widely or as long.
Gavins Leeches
I am not an English driving instructor, nor an Irish bank manager, nor an Australian sheep farmer, nor an Australian sugar worker, nor a fictional occult band manager.
Illnesses
I suffer from degenerative DNA scrambling, increasingly lazy cells, irreversible methylation, terribly tangled proteins, disappearing stem-cell nooks, and ultimately oxygen poisoning, like everyone.
What's with all these accordions?
Information hiding is a basic condition of good large software; these accordions are a prose analogue. The hope is that, by tucking away wires, I can write long things without triggering anyone's TL;DR reflex.
It also sort of simulates a dialogue with the reader: I plant a question, and then they prompt for the response.
