Cheat codes

Most things worth doing take serious, sustained effort. If you want to become an expert violinist, you're going to have to spend a lot of time practicing. If you want to write a good book, there really is no quick-and-dirty way to do it. But sustained effort is hard, and can be difficult to get rolling. Maybe there are some easier gains to be had with simple, local optimizations. Contrary to oft-repeated cached wisdom, not everything worth doing is hard. Some little things you can do are like cheat codes for the real world.

Take habits, for example: your habits are not fixed. My diet got dramatically better once I figured out how to change my own habits, and actually applied that knowledge. The general trick was to figure out a new, stable state to change my habits to, then use willpower for a week or two until I settle into that stable state. In the case of diet, a stable state was one where junk food was replaced with fruit, tea, or having a slightly more substantial meal beforehand so I wouldn't feel hungry for snacks. That's an equilibrium I can live with, long-term, without needing to worry about "falling off the wagon." Once I figured out the pattern -- work out a stable state, and force myself into it over 1-2 weeks -- I was able to improve several habits, permanently. It was amazing. Why didn't anybody tell me about this?

In education, there are similar easy wins. If you're trying to commit a lot of things to memory, there's solid evidence that spaced repetition works. If you're trying to learn from a difficult textbook, reading in multiple overlapping passes is often more time-efficient than reading through linearly. And I've personally witnessed several people academically un-cripple themselves by learning to reflexively look everything up on Wikipedia. None of this stuff is particularly hard. The problem is just that a lot of people don't know about it.

What other easy things have a high marginal return-on-effort? Feel free to include speculative ones, if they're testable.

I've noticed that people who have a hard time in intro-to-physics classes usually fail in a fairly predictable way: they see a problem, don't know how to solve it, and stop. But there's a trick to solving physics problems when you're not sure how. The general method is:

  1. Make a diagram or something, to depict what you know about the problem and make it easier to figure out stuff you don't know.

  2. Look at the problem until you can derive something you don't already know. Even if you have no idea how it will help (or if it will help) do the calculations, and write them down.

  3. Repeat step 2 until you see how to get to the answer.

The problem is when someone, not seeing a way all the way to the solution, stops trying instead of looking to make incremental progress.

I'm sure this applied to more than introductory physics problems. It's very similar to Terry Tao's advice on how to do math:

I don't have any magical ability. I look at a problem, and it looks something like one I've done before; I think maybe the idea that worked before will work here. Nothing's working out; then you think of a small trick that makes it a little better but still is not quite right. I play with the problem, and after a while, I figure out what's going on.

Most people, faced with a math problem, will try to solve the problem directly. Even if they get it, they might not understand exactly what they did. Before I work out any details, I work on the strategy. Once you have a strategy, a very complicated problem can split up into a lot of mini-problems. I've never really been satisfied with just solving the problem. I want to see what happens if I make some changes; will it still work? If you experiment enough, you get a deeper understanding. After a while, when something similar comes along, you get an idea of what works and what doesn't work.

It's not about being smart or even fast. It's like climbing a cliff: If you're very strong and quick and have a lot of rope, it helps, but you need to devise a good route to get up there. Doing calculations quickly and knowing a lot of facts are like a rock climber with strength, quickness and good tools. You still need a plan — that's the hard part — and you have to see the bigger picture.

That's like something I've found works with Colour Shift-- even if you can't see how to hook up a circuit and get the right colour, getting all the bulbs with the same colour on one circuit can be much more helpful than assuming that the part you've already got working shouldn't be messed with.

Neat game in the link! I played it until I ran into some non-obvious ones, solved them, and then thought about what kinds of AI code might automate the solution process. When I came back here, your analogy between the game and solving math problems changed from opaque to beautiful :-)

I wonder if there is a pedagogical application? Maybe it would work as a side exercise in the intro to math/physics classes, so you could use the game plus the verbal analogy to help students vividly experience the way that playing with a tough problem for a while can be productive?

I"m glad you liked it.

If you play Scrabble, it's also important to have ways to not get locked into the first word or near-word that occurs to you. If you're more serious about the game than I am, you'll have heuristics for getting closer to the best possible use of the letters you've got.

It wouldn't surprise me if it was possible to put together a course that covers a great deal of rationality with video games for examples. And which covers more of rationality by teaching how to design video games.

The first place I saw the claim that a huge amount of life success is encapsulated in many simple life optimization "tricks" (or "cheat codes" in your terminology) was in David Allen's book "Getting Things Done" which is full of many such tricks (plus motivational exhortations) organized around the rough theme of efficiently increasing the number of one-off embarrassingly parallel actions you accomplish per day.

I prefer the term "technique" personally because when I tried using Mr. Allen's term "trick" it sometimes backfired and confused people into thinking that there was bad moral intent involved. They could teach me one, and I would be happy and exclaim "That's an awesome trick!" and they would get defensive instead of take it as the compliment I intended it to be. I suspect that your term "cheatcodes" will run into this problem even more dramatically because it literally contains the word cheat in it.

The term "technique" primes for things like skill development, kung fu, painting, and technology rather than "violation of social norms" so it is safer to use, but all of these terms are imprecise... For educational and linking purposes, I think it would be a good thing to track down and use a term that is (1) more precisely about this specific idea (2) was coined long ago by someone other than a LWer and (3) has positive resonances. Sadly, I'm not familiar with any term that fits this bill. Anyone else know a term? As a last resort, perhaps one could be imported from a foreign language or created from latin or greek?

In any case, here are some "techniques" I can think of off the top of my head:

  • The first and most obvious thing is simply "the meta-technique" which is internalizing how much of human development is simply composed of the acquisition and use of techniques. They can be noticed and learned if you keep your eyes open. They can be sought out and practiced if you can articulate their need and come up with key words for searching for them. You can ask people for them. First you have to know that they exist and can be learned.

  • In David Allen's book, he illustrated the concept with a particularly striking technique which is to put exercise clothes on as the very first step upon waking. This helps to make exercising a default action in the morning because there are fewer steps between you deciding to exercise later, and then actually exercising. Also, the effort of putting on the clothes (and making them dirty) creates a sunk cost that can deflect you from rationalizing yourself into not exercising that morning... it would be silly to put on exercise clothes and then not exercise :-P

  • Something I learned from a really good boss I had was a social engineering optimization summed up in the aphorism "What gets measured gets done". Unfortunately, this one is dangerous to apply naively because of things like Goodhart's law and social complications around other optimizing but it is still useful to know about.

  • My brother taught me an interesting one for situations where service relationships are important, tipping is appropriate, and you'll be making a series of purchases (restaurants in your neighborhood over weeks and months, a club over a night, etc): try to make your first purchase at a time when there is a lull in the customers and give a big tip and maybe make friendly smalltalk with the server. This makes them more likely to remember you with positive valence at later busier times.

  • A technique I've gotten a huge amount of use of over the course of my life is to notice when some big picture aspect of my life is less than ideal and seek out a book on the subject. Read, experiment, retain the good stuff. I learned this technique before I came across "the meta-technique" but they obviously dovetail.

(1) I think using the word "technique" rather than "cheat code" or "trick" is an excellent idea.

(2) You say that Allen suggests using the common human reaction to sunk costs (which is to count them as if they were relevant to the decision). Now, as far as I know, it may well be advisable to use error to combat error. However, let's not forget that considering sunk costs in the case of exercise might make it harder to ignore them when it counts.

Ars brevis?

I think the idea of "a quick art" is conceptually almost perfect but I'm not sure about the latin declinations/conjugations and it doesn't sound pleasing to me somehow, as in "That's a neat ars brevis you showed me, thanks!"

Thinking about it more maybe "lifehack" is so close as to be as good as we're going to find? The quibbles I have with it still are:

  • Whereas "a technique" is too generic, "a lifehack" it feels too narrow -- like I wouldn't expect someone to share a solution to a solution to a common failure mode in physics classes if asked for a "lifehack". I think the perfect word would be a parent category for lifehacks :-)

  • Like a trick or a cheatcode, a "hack" also has negative connotations with many people, either as a malicious computer break-in or as a sloppy solution one step up from a kludge. It would be nice to have a word that someone unfamiliar with would be complimented to hear applied to a technique that they have shared.

Putting on your exercise clothes doesn't create a "sunk cost", you have to put on something, after all. It removes an impediment to exercising - the need to change into your exercise clothes if you are wearing something else.

It's a sunk cost if your exercise clothes aren't suitable for whatever things you were going to do other than exercising, such as going to work.

In my view, if your exercise clothes aren't suitable for whatever else you were going to do, then you aren't exercising particularly well. If the point of exercise is to strengthen the body and thus prepare it for potential adverse circumstances, isn't it best to wear that which you wear under normal circumstances so that your training matches reality as closely as possible?

I have a friend who says this is why she won't take martial arts. She invariably wears a skirt, so if she were ever called upon to actually defend herself, she'd have to do it in a skirt; yet no dojo will permit her to learn while wearing a skirt in the first place.

I forget, what's our term for 'counter-arguments which are bogus and not actually why a person disbelieves what they disbelieve'? I'm sure we have one.

Anyway, this is a classic example. First, her argument is internally weak. What, the physical conditioning will be of little benefit? The hand strikes will simply not be useful? The reflexes cease to operate when she is in her mufti? The skirt reduces any footwork (not even talking about kicks here) to utter uselessness? And so on. Risible.

Second, not to insult your friend, but either she knows very little about martial arts or she hasn't asked anyone who does have a modicum. There are plenty of martial arts which have uniforms functionally identical to skirts. From http://en.wikipedia.org/wiki/Hakama#Men.27s_hakama :

"Hakama are also regularly worn by practitioners of a variety of martial arts, such as karate, kendo, iaido, taido, aikido, ryu-te, and kyūdō."

(That's two empty-handed arts right there, which are both quite popular and common in the US.)

That surprises me. I would have though there were dojos out there that were a bit more pragmatic. At very least I would expect them to allow her to wear a white skirt over the top of the pajama uniforms.

Obviously it would rule out several schools of martial arts. Karate and Taekwondo would be out for example - too much reliance on kicking. I don't see why she couldn't learn judo, aikido or krav maga with that handicap though.

Then there are options available to her to learn to defending herself while wearing skirts despite not wearing them in practice. There is skirt choice - shorter skirts, fragile skirts and skirts that are easily removable all provide little penalty in combat. Practice in removing, cutting/tearing or moving the skirt to an unconstraining position would also serve her. But even ruling out those options she could simply have training in one of the practical martial arts and just not use any kicks higher than the assailant's kneecaps. Kicks are overrated anyway.

I remember someone once asked my Krav Maga instructor what he would do if someone threw a grenade at him, and he said "die?" (after he stopped laughing). While that's not strictly true-- there are ways to minimize your chances of being killed by a grenade-- it expresses a good point, which is that there are certain circumstances that martial arts aren't really designed to protect you for. Thankfully, though, those circumstances are unlikely to occur in civilian life, and knowing martial arts does help against the random drunk/crazy guy and the like.

Also, while there are good spaced repetition programs/databases out there (like Anki), the databases aren't collaborative like a Wiki, and in general could be much better.

Because WP is unstructured natural language, this is impossible to automate completely. It might be possible to automatically generate flashcards from something more structured like the entries in Freebase, but would you want to learn them?

If you are willing to do a little work, Supermemo has an idea of structured note-taking/editing, called incremental reading. SM has the most support for it, but really it's just copying the text into a text editor and expecting you to cut it down to notes and then to flashcards.

Also, while there are good spaced repetition programs/databases out there (like Anki), the databases aren't collaborative like a Wiki, and in general could be much better.

Agreed. If I were to tackle this, I would start with the Anki folks (Mnemosyne is too slow and conservative), and I would do something like write an Anki plugin to scrape a page inside a Category on a wiki (probably the card contents would be formatted using tables or templates), and then everyone just edits the page and any future downloads get the modified version. This wouldn't handle existing users getting updates, but that's the general problem of distributed revision control, which is certifiably Hard.

Actually, collaborative abilities aside, I think even a very well kept but closed database could be quite valuable (more so than Rosetta Stone or other such software for learning a language for instance).

I agree. What I intended was a markup language that editors could use. Then somebody could surf Wikipedia with some plugin installed so that marked facts would be highlighted in some way. Clicking on the fact would then bring up a box showing the relevant note card (or multiple variants), and you could select to add it to your database.

Currently the only surviving seller of SM flashcards that I know of is SM itself: http://www.super-memo.com/collections.html

My theory is that hand-made cards are good enough and often better than purchased ones; it's even harder for commercial ones to compete with the best freely-distributed ones. (Take a look at the samples for a number of the decks, like the assembler deck. My own assembler flash cards are better!)

The quality doesn't seem particularly great for the SM bought decks. For instance, for a foreign language deck I'd like to see images and native pronunciations, preferably from multiple speakers. For a chemistry deck I'd like to see 3D representations of molecules, preferably in multiple manners (ball-and-stick, spheres, etc), even better if the flash card allowed for rotational viewing of the molecule.

I definitely wouldn't buy any of the decks I saw on SM.

I don't want to sound like too much of an evangelist, because I'm not amazingly skilled myself, but when I saw the heading "cheat codes" I immediately thought "lifting weights."

If you're interested in looking (conventionally) good, feeling well, and making progress in physical performance, and if you don't have any physical problems that make it impossible, free weights are sort of the "secret weapon" that most people aren't using. Quite a few people who can't lose weight (or fat) with cardio, can once they try weights (this is true of me, on a small scale.) The added advantage is that you save time. (>8 mile runs may be pleasant on occasion, but they sure do take a while.)

Once I started doing some free weights exercise, I got the unexpected bonus of enjoying other physical activity a lot more (or at least disenjoying it less), because it became less tiring. I found I would spontaneously do things like sprint up the metro escalator or several flights of stairs, without being winded when I got to the top.

I do kettlebells; more conventional free weights may or may not produce the same effect, though I started with the latter..

This is very interesting to me. I've been lifting every morning for the past month or so, and have been quietly annoyed with myself for almost always lacking the willpower to just spend 20 minutes on an elliptical. Should I still expect losses once I've built some muscle mass?

Actually, now I think of it, I'm pretty down. I'm gonna make a second gym stop on the way home -- thanks for priming the option ^_^

Ellipticals are horrendous. I can't spend 20 minutes on an elliptical. Something about it is just willpower-sapping and no fun at all. Try doing something outside.

As I understand, complexes (switching from one lift to another with no rest) are a perfectly sound fat-loss workout no matter how advanced you are. If you hate all cardio, complexes are just as good.

I've spend over 20 hours per week on ellipticals for over a month before. One of the major aspects of my approach to exercise is "quantify everything mercilessly," and having readouts for how fast I'm going, heartrate, calorie burn, etc. made it more attractive than just running outdoors.

(I'll note that I don't consider this to have been particularly sane behavior; it was accompanied by some extremely harsh diet restrictions, and it probably had a lot to do with a resurfacing of old eating disorder habits.)

I wouldn't play music or anything while using them, I would just zone out, and let the whole experience blur together. It made the sessions feel much shorter in retrospect than they actually were.

I generally use treadmills instead when they're available, but running outdoors is pretty near the bottom of my list for enjoyable forms of exercise.

Even if you can maintain a 5 minute pace, 40 minutes is a sizable time sink. I can get a killer workout in the gym in 20 minutes, or I can get an even more intense workout on a 100 meters of flat ground in 5 minutes (although, to be fair, recovery time after sprints is quite substantial if you're not in shape =P ).

I'd run out of breath in 5 minutes during running anyway. I don't have such problem with activities like weight lifting or boxing where there are regular breaks after 20 to 180 seconds of activity to pant and catch my breath. Maybe I need to learn breathing. But so far, the idea of any physical activity without these breaks seems preposterous to me. I haven no idea what runners do.

I also have the impression that via all these activity - break and panting -activity - break and panting - I am cheating myself with willpower through activities without really engaging my cardiovascular system.

When you're feeling depressed for no good reason, force yourself to laugh. It triggers happiness almost as well as externally-induced laughter. Eventually, you will noticeably condition yourself to release seratonin (or endorphins, or something) every time you notice that you're seratonin-deficient.

It's been effective for me. I started it as a moody teenager and it quickly became self-perpetuating. Google suggests I'm not alone. It's got a whiff of wire-heading, I admit, but ideally you're using it to solve a brain chemistry defect, not an external problem.

I do this. Sometimes I just smile. Sometime's I just 'choose' to feel good, as if I've learned to control a new muscle and don't need to go through the intermediary of laughing or smiling.

The effect is very short term for me, and I can't maintain it while I work. It's great for relaxing though.

Taking a physical action, such as smiling, makes it easier to maintain. I actually learned this trick back in the eighties from a book Self-Creation by George Weinberg. Your attitudes and general outlook tends to follow your physical actions as much or more than the other way around. So act how you want to feel, then you will become more like you act.

Well, since you mentioned expert violinists...most people find that guitar is alarmingly easy to learn once they sit down with it. With a 1 hour lesson per week and 30 minutes of practice 3 times a week for 10 weeks, most people can get to the point where they are affirmatively entertaining -- much more fun to listen to than silence or small talk. Being able to play an instrument reasonably well is good for making friends, impressing people, expressing emotions, achieving flow, and improving self-esteem.

Unless you're a perfectionist, extremely busy, or extremely lazy, you will probably find that after the first 5 hours or so of time-investment, both the lessons and the practice can be a lot of fun -- you don't have to follow a rigid system; you can just see interesting techniques used and then copy whichever ones interest you as best you can, and music comes out.

There are probably some other instruments it works for, but it does not seem to work that way for most classical symphony instruments, e.g. trumpet, clarinet, viola, etc.

It seems as if the guitar benefits from these qualities:

  • Sufficient tonal depth to sustain a melody (i.e. not a drum)
  • Sufficient harmonic depth to be a solo instrument
  • Since it's a "plucking" instrument (rather than blowing or bowing) it's less sensitive to the quality of the musician's touch - an amateur can play a single note almost as well as a professional

Am I missing some crucial element? It looks like these attributes are not all present in the drum, trumpet, clarinet, viola, &c., but are all present in the piano, harpsichord, harp, &c. Maybe piano, harp, and harpsichord are all more difficult to learn than the guitar?

  • Rock, pop and folk music, the things guitars are popularly used for, are quite simple, so you don't need to be able to play well at all to get music out of the thing. (Think how many punk rock bands could literally hardly play when they started. "Here's one chord, here's two more, now form your own band.") Also, you can get a guitar and amp that are good enough for your whole career way cheaper than the typical good classical instrument.

That's a good analysis, and the harp and electronic keyboard are both easy instruments to learn. I would add that the guitar also allows for:

  • nearly mindless strumming that will still produce many interesting variations on popular chords

To get, e..g, different kinds of E Major sounds on a piano, you have to remember the finger shape for E Major and move it the correct number of spaces up and down the keys. To get that on a guitar, you just move one hand rapidly back and forth, hitting different strings at random. Maybe you occasionally release a finger on your nondominant hand.

Out of the instruments that are usable for both melody/soloing and harmony/accompaniment, the guitar family has the clinching virtues of being cheap and portable. Like keyboard instruments it is also applicable to virtually any genre of music. K/b instruments are more suited to complex material (hence their use in composition), whereas the guitar family allows more expression than instruments that are essentially controlled by switches.

These advantages entail one overriding disadvantage: ever other bugger plays one. So it is proportionally harder to get into a band or college. If you want gigs,play something cumbersome, like drums, double bass or euphonium.

For improving writing skills, the two most effective methods I know are:

  1. Participate in National Novel Writing Month. The idea is to write a 50,000 word work of fiction in 30 days, without fretting over quality too much. If you do this, you will learn a lot. It's unavoidable. (Plus, you get a book with your name on it. That's a great feeling.)

  2. Write blog entries, and post them somewhere people will see and discuss them. Less Wrong, for instance, or Hacker News. If you know you're writing for an audience, it forces you to clarify your thoughts, and put more effort into writing well. This is good practice, and you get feedback; commenters on the internet are usually pretty blunt.

Each of these techniques exercises a different type of writing, so they're complementary.

Brilliant! I think we often have a hard time seeing these cheat codes. One reason for this might be the following (OK, a bit speculative, granted)

Gladwell or Taleb writes in some book that we have a gut feeling that there should be a correspondence between cause and effect: we have trouble of conceiving of significant effects (e.g. the president of the US being murdered) as having trivial or uninteresting causes (i.e. a lunatic). Instead we postulate that there must be a significant cause - e.g. a Sovjet conspiracy. Similarly, we have trouble conceving of significant events as the result of randomness, but postulate that they must have significant causes.

(I don't know if there is a name for this bias, or if it indeed has been proven in experiments. It seems intuitive that we have it, though.)

In line with this, it might be that we think that effort (i.e. cause) and benefit (i.e. effect) normally should match each other. If this is right, this would perhaps go some way towards explaining why humanity invented so little for such a long time, even though many inventions that increased productivity were relatively easy to come up with.

Of course people do invent, but it would seem to me that this is to large extent an attitude we've learnt from the scientific revolution and onwards - it is not our primary biological disposition.

Also, in many cases it is of course true that attempts at "easy solutions" are misguided (as mentioned in the OP) - so there is some ground for the heuristic that benefit and effort do match (perhaps particularly in a fiercely competetive and inventive society such as today's Western society). But like all heuristics, it is not always helpful (though it is so on average).

In any case, the fact that we seem to have trouble spotting these cheat codes makes it particularly useful to discuss them as is done here.

Spaced repetition is good for learning, but you need to be using it all along. You are basically "reviewing" the material, like for an exam, but in smaller doses, continuously. It does not help you cram if you haven't been keeping up. The "spaced" part is based on refreshing your knowledge just as it is fading from the previous repetition. As time and repetitions pass, the repetitions can get farther apart, because it is increasingly "fixed" in your memory.

It depends on # of repetitions and whatnot. http://www.gwern.net/Mnemosyne.html#fn3 :

"With himself as the subject, Ebbinghaus found that for a single 12-syllable series, 68 immediately successive repetitions had the effect of making possible an errorless recital after seven additional repetitions on the following day. However, the same effect was achieved by only 38 distributed repetitions spread over 3 days"

This wouldn't work with the SM-2 algorithm that Anki and Mnemosyne use; you would grade the series flashcard highly after a few repetitions and then it'd get pushed out a few days. So you'd have to lie to it - the SM-2 algorithm is meant to use as few repetitions as possible over the long term. It optimizes for retention over years, not days.

Anki does have a 'cram mode'. I don't know how it works or whether it trades efficiency (in # of repetitions) for retention in the short term (next few days).

The general trick was to figure out a new, stable state to change my habits to, then use willpower for a week or two until I settle into that stable state.

How do you define a "stable state"? Also, using willpower is not as simple as you make it out to be.

How do you define a "stable state"?

A stable state is one which you fall back into even when perturbed a bit. For example, some people with drinking problems intend to have "just one drink", but that one drink leads to another drink, which leads to another, and before they know it, they're drunk. For these people, attempting to have just one drink is not a stable strategy, because it leads to a second drink (and so on). For many of these people, it would be easier to not drink at all; therefore the stable equilibria are not drinking or getting drunk.

Also, using willpower is not as simple as you make it out to be.

Feel free to elaborate.
