Comment by bfinn on Social Dark Matter · 2023-12-04T18:03:09.281Z · LW · GW

Somewhat relatedly, about 10 years ago I heard someone on the radio predicting that a long-term effect of social media would be greater acceptance of others' flaws, particularly youthful indiscretions that previously would have damaged a policitican's career - e.g. that they had smoked marijuana at college.

Such indiscretions would now be permanently documented on say Facebook when they occur. So everyone would gradually get used to the idea that such things are widespread and almost-normal, and almost all future politicians would be found to have such flaws/misdemeanours in their past. Expecting them to have none would become unrealistic, and if anything a politician with nothing bad visible in their past would seem not just squeaky-clean but abnormal, perhaps even weird.

This seemed quite a profound observation at the time, at least for the kind of analysis usually heard on the radio. But in the 10 years since I haven't particularly noticed this trend in public attitudes emerging. Or at least, judging by social media (probably unwise), in many ways there seems to be less tolerance than before. Or more likely a mixed picture - there is more tolerance of some things (e.g. being trans) but less of others (e.g. unfashionable views), and (as is often observed) social media amplifies intolerance as it makes for stronger clickbait. So possibly the overall trend in tolerance, or at least of tolerance apparent on social media, is flatter than predicted.

Re departmental historians: the UK's Foreign Office does have (or had) a small team of historians; someone I know was one of them for a year or two. Apparently they were writing up the history of the Foreign Office in chronological order, at slower than real time; hence were falling further and further behind. They had got up to 1947 or something, but would never catch up. When they completed the history of a year, it was published in an internal book (I assume not publicly available due to national security etc.), which went on a shelf and no-one ever read.

Each year the historians had to submit a justification for their continued existence. The guy I know said there was none, and they should just write: "The Foreign Office should close down its history department."

I suppose what this shows is that if internal historians have a use, it's important that they know the full departmental history, particularly recent decades; they are involved in departmental decisions; and the history is as up-to-date as possible.

The thickness has units of something like [effect]/[work]

I.e. presumably benefit/cost (work being a cost, whether financial or not), = the benefit-cost ratio (BCR) used in cost-benefit analysis in economics.

Comment by bfinn on Losing the root for the tree · 2022-12-31T00:32:16.407Z · LW · GW

Is the moral of this really that all decisions should be made so as to maximize the ultimate goal of happiness x longevity (of you or everyone), in utilitarian fashion; whereas maximizing for subgoals is sometimes/often a poor proxy?

Or is it impractical to do utilitarian calculus all the time, but calculations/heuristics with the thin and thick lines can clarify the role of the subgoals so they can be used as adequate proxies?

(It's partly unclear in my head as I didn't grok the exact meaning of the lines & their thicknesses. And it's too late at night for me to think about this!)

Comment by bfinn on Third Time: a better way to work · 2022-11-17T21:54:22.065Z · LW · GW

Others would have to report whether they find it more useful than what they do now (eg Pomodoro), but the reason I think it may well be is indeed the fact it fixes the various Pomodoro problems.

Re new downsides Third Time itself introduces, the one I'm aware of is indeed its extra complexity - hence it is best implemented in an app. But if others find other downsides, I'd be interested to hear of them.

(Alas I haven't got round to finishing Part 2 yet - been busy with other things, notably analyzing the academic research into what the best ways to spend a break are, which I'll write up in due course.)

Indeed - or simply break after completing a task - which also counts as a reward, hence an incentive to complete it. With the downside that you may be less motivated to resume work than if you're breaking in the middle of something.

On a detail (!) there are mouth guards (‘sleep clench inhibitors’) that you wear in your sleep to train you not to clench/grind your teeth both at night & in the daytime. I’ve used one; my dentist got one custom made to fit my teeth. You wear them nightly for a week initially, then just once every week or two. Unpleasant the first couple of nights, but you soon get used to them. Worked for me!

Otter (a smartphone app) is very good. So I've started using it recently for taking notes. Haven't tried using it to write an extended post about anything, though it could be a useful way of getting a first draft.

I like this idea of getting others to help write up ideas. I find writing up ideas vastly more time-consuming and difficult than thinking them up, or explaining them verbally. Even Eliezer, an expert writer, seems to have taken years to get round to writing up his recent list of AI risks.

Comment by bfinn on Excerpts from a larger discussion about simulacra · 2022-06-24T08:13:56.694Z · LW · GW

When I was halfway through this and read about the 4 stages, they immediately seemed to me to correspond to four types of news reporting:

  1. Accurate reporting
  2. Misleading reporting (i.e. distorting real events, and fooling many people)
  3. Fake news (i.e. completely made up, but still pretending to be news, and fooling some people)
  4. Obviously false or 'pure fiction' (i.e. not even pretending to be news, and fooling no-one). You do get this kind of thing in the crappiest tabloids like the UK's Sunday Sport or maybe the US's National Enquirer. A well-known example in the UK was the front-page headline 'Freddie Starr [a TV comedian] ate my hamster'. (Such absurd stories evade the UK's strong libel laws if no reasonable person would believe them, so the more outrageous, the better.)

Which isn't exactly what the post is about, but might be a useful analogy, or source of terminology.

Comment by bfinn on How do I use caffeine optimally? · 2022-06-22T21:37:33.365Z · LW · GW

The focus produced by caffeine is enhanced by theanine (or L-theanine), which also counteracts jitters/headaches caffeine can otherwise induce. You can buy theanine in capsule form. Take 1-2 times as much theanine as caffeine. So for a cup of coffee (either brewed, or containing 2 shots espresso), which contains roughly 150mg caffeine, take say 200mg theanine.

You probably shouldn't routinely have more than 1 cup of (caffeinated) coffee a day if you want to avoid becoming tolerant of it, which removes its effects. And don't drink it in the afternoon or evening, to avoid disturbing your sleep (which may not be obvious, as your sleep can be disturbed even if you have no trouble falling asleep).

Alternatively drink tea, which has far less caffeine than coffee - so you can have as many cups as you like. Tea also contains some theanine (though rather less than the optimal dose).

Comment by bfinn on Theses on Sleep · 2022-06-22T19:59:33.870Z · LW · GW

I heard recently that sleepio is now prescribed by the UK's National Health Service, so has presumably been clinically demonstrated to be very effective.

Comment by bfinn on Chain Breaking · 2022-06-18T16:45:07.034Z · LW · GW

Mark Forster, the best productivity author I've read (even though I don't agree with all of his ideas), makes a similar point in one of his books. Though he doesn't frame it as finding the weakest link in the negative chain. Rather, as identifying the break in the positive chain that normally makes you act correctly, in cases where you usually get it right, e.g. if usually show up on time for a meeting, but sometimes fail to. You have to think through what actually happened this time that made it go wrong - exactly where did the chain break, and why, and what can you do to avert it? E.g. the traffic is usually OK but this time was bad, so you should always check the traffic in advance, or aim to arrive early.

Indeed. In fact IIRC the fact nuclear missiles were based there was secret at the time and long afterwards

Comment by bfinn on Third Time: a better way to work · 2022-05-18T16:03:13.245Z · LW · GW

Third Time means '1/3 of the time' (referring to break time = 1/3 of work time) and also 'the 3rd occasion'. It's only half a pun because 'the 3rd occasion' doesn't refer to anything here, but it's a common phrase like first time, second time etc. (E.g. 'the first time I ate caviar I didn't like it, nor the second time, but the third time I enjoyed it'.)

As for puns in the other names suggestions, there are too many to explain, I'm afraid!

Re the Malmstrom incident, there have been various reports over the decades of UFOs appearing at nuclear missile sites and even apparently interfering with (eg disabling) the missiles. Eg the Rendlesham Forest incident in 1980 at a USAF nuclear base in the UK, in which deputy base commander Lt Col Charles Halt and many other personnel spent hours observing (and filming, photographing etc.) UFOs over two nights.

(I'd link to the Wikipedia article, but last time I checked a while back it was being gatekept by ultra-skeptics who reverted any changes. I have however seen Col Halt describe the incident at great length & detail. An audio recording he made as the events were unfolding is also in the public domain, though he says radar tapes, film and photos were all taken away on higher orders and never seen again.)

Comment by bfinn on Lies, Damn Lies, and Fabricated Options · 2022-05-17T14:35:05.718Z · LW · GW

Great post.

'Fabricated' doesn't seem quite the right adjective, as it implies deliberate deception, whereas your examples suggest it's usually unintentional. Indeed I initially assumed your post was about some kind of rhetorical trick rather than a mistake. So, how about something more along the lines of 'incoherent'? (Or see related terms below.)

In any case, I'm a bit wary of the introduction of new terms for apparently-new concepts, because they are often already quite well-known and built into English via established phrases, which to save brain space should be used as well or instead. (E.g. 'desperado' and 'chasing losses' for the otherwise perhaps surprising 'discovery' of risk-seeking behaviour in a loss situation.)

That said, I haven't thought of any existing phrases which precisely capture fabricated options; but FWIW here are some related ones:

  • You can't have your cake and eat it too (which you touched on)
  • Hand-waving
  • Utopian / Fantasy world / Dream world / La-la land 
  • Wishful thinking / Pipe dream / Chasing rainbows / When pigs fly / Pie-in-the-sky / Castles in the air.

Utopia(n) is actually an #EXAMPLE - cf the meme about communism leading to Utopia via an unspecified intermediate step. Which IIRC Scott Alexander said seemed to be Marx's position - Utopia just follows automatically, no further elaboration or detail required.

Also, a couple of nitpicks:

  • The Twin Earth example was originally (AFAIK) from Saul Kripke in his book Naming and Necessity
  • 'The actual price of the goods and services' should read 'The actual cost...'
Comment by bfinn on Science in a High-Dimensional World · 2022-05-16T13:43:48.656Z · LW · GW

An issue I find with debugging a complex program is that when you write tests (which put inputs into part of the program and then check whether the expected output is produced), your tests can themselves contain bugs, and often do (if they're not trivially simple). That is, your experiments isolating a small set of variables can produce confusing results due to the experimental design, not just unpredictability in what they're trying to test. Eg maybe your way of measuring the slope angle or sled weight is flawed. (Cf assumptions about the speed/straightness of light or a steady-state universe messing up your astronomical observations). As philosophers of science say, all observation is theory-laden.

I don't know anyone enlightened, so I'm not making a claim either way. Just that if this is roughly what enlightened is meant to mean (I surmise via the drawing analogy), then this might be an expected consequence, hence test, of it.

Comment by bfinn on Kenshō · 2022-05-09T14:29:14.723Z · LW · GW

If Looking is something like bypassing one’s own mental machinery that interprets & somewhat distorts reality, then maybe someone who’s enlightened has few cognitive biases, or at least is capable of noticing & maybe bypassing them when they arise?

Comment by bfinn on The glorious energy boost I've gotten by abstaining from coffee · 2022-05-08T11:54:04.512Z · LW · GW

[EDITED] I recommend tea (black, green, oolong or white - i.e. white leaves, not with milk). As well as being rather lower in caffeine than coffee, tea includes L-theanine, which (a) increases the benefits of caffeine (viz. attention, accuracy, energy) and (b) counteracts jitters and headaches from caffeine.

Oolong tea usually has a bit more caffeine than the others, though green & white teas have a somewhat better ratio of L-theanine to caffeine. But caffeine and L-theanine contents are very variable anyway.

Comment by bfinn on Typology of blog posts that don’t always add anything clear and insightful · 2022-05-05T21:18:11.191Z · LW · GW

Thanks for this - interesting & quite useful. It reminded me of some similar observations:

George Orwell recommended somewhere that, when writing, you should try to visualize what you want to say for a while (i.e. non-propositionally) before making any attempt to put it into words, so as to be concrete rather than abstract/dry and falling back on cliches etc. that may not express it adequately.

At the end of Wittgenstein's Tractatus Logico-Philosophicus - the gist of which is that any meaningful statement can be expressed as logical propositions - he hints enigmatically that this isn't quite the be-all and end-all, as some things that can't be said can still be 'shown'. I assume meaning, gestured towards non-propositionally. An example he gives elsewhere, maybe along these lines, is that you can know how a clarinet sounds, but not state it.

The typical reader needs to meet the idea repeatedly, from different angles, to start to realize it.

Cf in Philosophical Investigations, W. makes various points repeatedly in different ways via different examples, and justifies this by saying it's like repeatedly traversing a landscape which you need to view from different angles before you can understand the whole.

(Contrast the Tractatus, where IIRC in the intro he says maybe the book can only be understood by people who've already had the same thoughts. Maybe, in line with the whole book, on the grounds that if you can't understand propositions, he can't help you further (via non-propositions).)

Comment by bfinn on Bring Back the Sabbath · 2022-05-02T21:27:37.443Z · LW · GW

An obvious point just about worth mentioning, is that of course you don't need to spend a whole day over Sabbath. A half- or third-day per week is a lot better than none. Albeit perhaps increasing the chance that you'll start thinking about post-Sabbath plans during Sabbath (if it ends before night).

Relatedly, if Sabbath is to be a whole day perhaps it's better lasting from waking up until bedtime (or notionally say midnight to midnight), so it is bookended by the natural boundaries of sleep. (Albeit that reduces the point of the candle-lighting ritual.)

Comment by bfinn on Sabbath Commentary · 2022-05-02T19:36:16.580Z · LW · GW

You may or may not know there's a blog called the Ancient Wisdom Project which tries out practices from various religions for a month at a time.

Comment by bfinn on Bring Back the Sabbath · 2022-05-02T18:04:22.305Z · LW · GW

One issue I have with the regular meal with friends/family bit is that (aside from those in your household, who you would see anyway) this potentially sets up a regular commitment which could well become onerous. In that, if you establish a pattern of seeing the same people week after week, you may after a while start to get bored of it/them (even close friends can pall if seen too often), and want to see other people, or no-one, for the Sabbath meal. Which starts to make Sabbath tedious/stressful if not dealt with, and even if dealt with delicately can create an awkward situation.

(Cf during COVID lockdowns my family set up a weekly Zoom meeting, with its own 'rituals' such as a quiz. This got quite tedious after a few months, with nothing much new to say, connection problems, the calls tending to overrun for no good reason, etc. etc. It was eventually broken only by people starting to drop out with excuses, after a few weeks of which everyone got the hint and it finally ended, having long outstayed its welcome.)

Comment by bfinn on Bring Back the Sabbath · 2022-05-02T17:53:06.573Z · LW · GW

They prevent accumulation of personal-and-home-related work debt. A chaotic house is not restful. Postponed chores weigh on youThe deadline forces handling them in advance.

Cf a friend of mine once observed that taking a vacation has the benefit of forcing you to clear your desk of things beforehand - completing, ditching or delegating tasks, clearing your email backlog, etc. Often in a more decisive and forceful manner than you otherwise would, e.g. declining to do things you've been asked to do, finishing mini-projects in quick-and-probably-good-enough ways rather than spending too long over them, etc.

Comment by bfinn on Bring Back the Sabbath · 2022-05-02T17:43:10.893Z · LW · GW

Re the last point, yes indeed. Mark Forster (an excellent productivity author) recommends training yourself to comply with your own resolutions this by, each evening (for a while), deciding on something big or small that you will do (or not do) the following day without fail, no matter what. Then do so, and repeat.

Or if you’re paid by results not the hour, as a contractor, you can earn the same in less time. Or even as an employee, you can just be paid to waste most of your time (though this is fairly unsatisfactory). Eg a friend of mine worked with an excellent programmer who would do nothing for months - literally spend most of the time in the pub or messing around with things that interested him - and occasionally spend a weekend programming furiously to produce what was presented to the (crappy) management as what the entire team had been working on for months.

Comment by bfinn on Consider Taking Zinc Every Time You Travel · 2022-04-12T11:05:02.802Z · LW · GW

Last time I looked into all this a while back, eg on Examine.com - an excellent site which analyses research on supplements - Healthspan Elite Zinc Defence Lozenges seemed to be the only suitable zinc lozenge available in the UK for treating colds once you have them. Doesn’t come with instructions (!) but as soon as cold symptoms start, dissolve slowly in the mouth and avoid eating/drinking for say 15 min afterwards, and avoid citric acid for a while before too. You need to take 9 lozenges (1 sheet) per day.

Examine.com also suggests black elderberry, eg Sambucol Immuno Forte. High doses of vitamin C may also shorten colds slightly, and help prevent them in people who have very high physical activity eg athletes & soldiers. Zinc (swallowed pills, not lozenges) may also help prevent colds.

Evidence for all these things is weak IIRC but fairly harmless to try, particularly if (as for me) your colds are frequent, persistent, or annoying.

Comment by bfinn on bfinn's Shortform · 2022-04-04T16:03:43.152Z · LW · GW

A good, plausible movie about AI risk might be an indirect way to raise the chance of government action via public awareness (if that would be useful). Have there been such AI risk movies that I've missed? If not, how could people get one to happen?

Cf I get the impression governments take asteroid risks a bit more seriously thanks to various asteroid-strike movies over the years. Not least the recent Don't Look Up on Netflix, which despite being a comedy was probably quite thought-provoking to many viewers (e.g. showing how there could well be government & public denial, resulting in disaster).

When reading Superintelligence by Nick Bostrom it struck me parts of it would make excellent movie plots. Eg the AI's ingenious ways of escaping an AI box by social engineering. (Though, googling, I see that a dire-looking romcom called Superintelligence, perhaps inspired by but very far removed from the book, was released in 2020.)

Comment by bfinn on Steelmanning Divination · 2022-04-02T14:53:49.040Z · LW · GW

Cf The Dice Man (a good idea for a mediocre book), in which the protagonist decides to make all decisions large & small by rolling a die.

But (and I don’t recall if the book discusses this) much then comes down to what 6 options to choose from - a decision made entirely by the protagonist. Eg if you fall out with Fred, do you include ‘punch Fred’ or ‘kill Fred’, or merely ‘criticise/ignore/undermine/forgive Fred’? And what proportion of options should be nasty vs nice?

And perhaps that decision (deciding the options) is more instructive than just making a decision cold.

Comment by bfinn on What’s wrong with Pomodoro · 2022-03-31T08:10:29.458Z · LW · GW

(1/3 feels like a bit too much though, e.g. 8 minute break for each 25 minute pomodoro. 1/5 to 1/4 would be closer to classic 25-5)

Actually if you take into account the longer break every fourth Pomodoro it works out close to 1/3. (Office workers not following a system effectively use fractions more like 1/5, the research shows, but most of them don't work in intense bursts.)

Comment by bfinn on What’s wrong with Pomodoro · 2022-03-29T20:15:03.072Z · LW · GW

If you're in the flow, do you take the break anyway or skip it? If you skip it, it might be best to save the break up for later, so you get a longer break after longer work (somewhat like Third Time). As the academic research suggests, not surprisingly, that people need longer breaks after working longer.

I think making pomodoros longer when you're in flow makes sense, as does making them shorter if you're distracted because your attention span is short today. Though being distracted or interrupted by something external outside your control doesn't seem a reason to shorten the next pomodoro.

I suspect it's best to take breaks when you need to, but maybe within a given day that's at a fairly constant interval - even if it varies from day to day depending on your energy and what you're working on. Your method would be a way of homing in on that optimum length for the day. The academic literature (which I'm currently reading more of) unfortunately doesn't have much research about whether it's better in general for breaks to be fixed or taken whenever you like.

They seem fairly similar, but e.g. psychopathy is often hidden by psychopathic charm, used to manipulate people 'nicely', whereas it seems the mafioso nature's effectiveness comes from others knowing you have it and believing your threats.

If psychopathy is an evolutionary strategy, keeping it hidden presumably means people don't avoid/kill you. Or maybe psychopaths only keep it hidden until they get powerful enough that they are fairly safe, then reveal it in order to issue credible threats like a mafioso. (E.g. some dictators.)

Some years ago I did read research showing that improving sleep quality was the easiest intervention most people could make to improve their happiness. (I don't recall where, but googleable no doubt.)

Re sleep deprivation inducing mania, I sometimes fast (either on 100kcal or 700kcal per day for 5-6 days), and find (as others do) that after a day or so I go into a hyperactive state - very alert, clear-minded, energetic, probably not far from mild mania. (And unlike as described in the OP, I don't get hungry at all - or rather, only did the first couple of times I fasted. So it presumably it just takes getting used to.)

So I wonder if the analogies between sleep and eating are even closer than suggested.
