Most of your examples seem more like "prerequisites" or basic skills that you build on. But scaffolding is a thing you build up to get something else done, then get rid of afterwards. So, a scaffolding skill would be a skill that enables you to learn how to do something you actually want to learn, but once you have learned how to do that thing, you no longer need the scaffolding skill.

There are conventions pertaining to the style a letter is written in. You might have a as an arbitrary element in set A, while a₁, a₂, etc., are a sequence of elements in A, while fancy-boldface A or fancy-script A (I don't know how to render those here) could represent the class of A-like sets. Also, a′ would be another case of a, or maybe the derivative of a, while a″ would be a third case, or maybe the second derivative. Sometimes superscripts or backscripts are used, when subscripts are not enough. Sometime... (read more)

There is a related problem where many browser-based productivity tools follow design principles from websites that are trying to get clicks. For example, I commonly run into DB interfaces at work that will return, say, 10 (or 25, or other small number) results per page. Now, it's good design to not let a query that returns, say, a million results, crash the browser. But, if a few hundred, or even a few thousand, results will display within milliseconds, why make me page dozens (or hundreds) of times? (I'm looking at you, GitHub commit history!)

It seems to me this is an example of you and Kaj talking past each other. To you, B's perspective is "eminently reasonable" and needs no further explanation. To Kaj, B's perspective was a bit unusual, and to fully inhabit that perspective, Kaj wanted a bit more context to understand why B was holding that principle higher than other things (enjoying the social collaboration, the satisfaction of optimally solving a problem, etc.).

Except there's more at play than just winning the election. If you're a voter in a swing state, the candidates are paying more attention to you, and making more promises catering to you. The parties are picking candidates they think will appeal to you. Even if your odds of winning stay the same, the prize for winning gets bigger.

It was exiting a few elections ago when Colorado was in play by both parties. We even got to host the Democratic convention in Denver. Now, they just ignore us.

One thing you touched on, but didn't delve into, is that the various "pay" components will having varying marginal utility at different levels.

For example, if you're literally starving, "coolness" won't matter much, you need enough money to buy food! But if you have enough money, you start caring about other things.

Perhaps having some social interaction is important, and you would sacrifice other things to have at least some of that in your job. But, beyond a certain point, the value diminishes, and would likely go negative, as the constant socializing get... (read more)

The OCD in me objects to the colors not being in chromatic order. On the other hand, if you wanted to maximize visual contrast between adjacent colors, then a sensible order would be black, red, green, purple, orange, blue.

As a former teacher, I firmly believe that if we want to reform schools, we must reform the teaching profession and school management structures. At least, we should address the things that are most insane:

• A school district is a big operation, with many having thousands of employees, and budgets running into the hundreds of millions of dollars. And it is usually run by literal amateurs. As in, the school board is a group of unpaid volunteers.
• As tough as it is to be a teacher, consider what it's like to be a principal: You get the most odious parts of be

Ironic that "Maybe" seems to have one of the narrower ranges of probabilities...

The cell borders example is misleading. The readability issue is not the cell borders themselves, the issue is that the borders are heavier weight than the text, and there's no difference between the borders separating the row and column headers, and the borders separating the data rows and columns.

If your only choices for gridlines are "off" and "obnoxious", "off" seems like a good choice. And for small tables, no borders works well. But for larger tables, finer lines (maybe in a lighter color or shade) can really improve the readability.

In multiplayer games, one balancing factor is that other players can gang up on the person who is ahead. Depending on the game dynamic, this can even things out a lot. In some games, this even creates the dynamic where you don't want to look too strong, so that others don't focus their attention on you.

Playing games against my kids when they were young, rather than just slack off and let them win, it was more fun for me to figure out the best way to handicap myself: What algorithm for sub-optimal play would keep the game close? Solving that puzzle effectively became my victory condition, rather than the game's victory condition, and I was effectively competing against myself, a more balanced opponent.

The question of what IS happening versus what SHOULD happen with population growth are certainly two different things. My point is that arguments for growth ultimately need to address the questions of how big should we grow, and what happens when we reach that point. If our economy depends on continued growth, that's going to stop working at some point.

While the physical limits of the universe are a long ways off, there are other limits that we could hit much sooner. Underlying your pro-growth arguments, there is an assumption that collective intelligence ... (read more)

The fundamental problem with these anti-Malthusian arguments is they ignore the fundamental reality that exponential growth is unsustainable. There are physical limits to the universe, whether you believe the earth can support 10 billion or 100 trillion, or if we can expand through the universe and achieve a billion billion times more than that, it won't take that long, with exponential growth, to get there. At a certain point, the entire mass of the universe has been converted to human flesh. Some point before that, we either stabilize, or collapse.

Where I live, I don't see many people going 15 over. I see most people going within -3 to +9 of the speed limit. They're following the law -- maybe not strictly as written, but as socially understood. There are a few people breaking the law -- and they get ticketed, etc. There are places where the speed limit is unreasonably low, and gets ignored (e.g. speed limit drops from 75 to 55 for construction zone, but no construction activity is visible), but in general, people around here follow the speed limit -- as socially understood.

Yes, when it comes to ordinary driving situations, there's only so good you can get, if you can get from A to B without trouble, without annoying and/or scaring your passengers or other people on the road, it's hard to do noticeably better. It's hard to get too much above the median; the 80th percentile driver won't seem that different from the 50th percentile driver. But, you can be really bad and drag the average down. Thus, the average is below the median, ergo most people (most drivers, anyway) are above average drivers. (Even assuming we are using some identical, objective scale, which, as jefftk points out, is not going to be the case.)

Just be careful your secure grip doesn't inadvertently cause the child an arm injury. "Nursemaid's elbow" and certain types of radial fractures can result from a hard yank on a child's arm.

Unendorsed while acting/Endorsed reflectively: This is not so strange a failure mode as you are indicating. You take some action, which at the time you know isn't right (execution failure). Later, you come up with some post-hoc justification for your actions. This is another failure mode to be aware of, affecting the postmortem.

Postmortems can have their own failure modes. We might disagree about the facts of what happened. We might have different perspectives on the context in which things happened. We might struggle to be honest with ourselves about our ... (read more)

Internally, though, people are not monolithic. In some ways, they are more like a mob. Even debating with one person, you can run into the same type of difficulty.

Upvoted. While I would hate to see this forum become another battleground for culture wars, I also don't want to see people avoiding topics because they touch on culture war stuff. Using Rationalist tools to deconstruct the dynamics of these battles (without fighting the battle) seems like a useful thing.

While I don't necessarily agree with the post, and I can see where it might, unfortunately, trigger some negative responses from some, I found parts illuminating, and it got me thinking about some useful reframing tools. All too often, people in the culture wars talk past each other because they are using the same words to point to different things.

It's hard to get good data, yes, particularly in a politically charged environment. But, I would have liked to have seen some evidence that for a given mitigation, our leaders tried to get a best estimate (even if it is not a great estimate) that it will prevent X COVID deaths, at a cost of Y (dollars, QALYs, whatever), and had done some reasoning why utility(X) > cost(Y). We might disagree on the values of X and Y, and how to compare them, but at least we would have a starting point for discussion. Instead, we got either "Don't take away muh freedom!" ... (read more)

There have been multiple egregious examples of this fallacy with respect to pandemic policy. The complete lack of rational cost benefit analysis (across the political spectrum) for the various measures was truly disheartening.

But to give a less politically charged example: Locally, in response to drought conditions, some restaurants announced they would only bring glasses of water to the table, on request. Now, this might make some sense in terms of reducing labor, although the extra work of having to ask everyone, and possibly bring out additional glasses... (read more)

I remember as a kid, about 12, loaning my less-mathematically-astute younger brother $4, at 10% interest per day, compounded daily. I remember gloating about how much money he was going to owe me. I was going to be RICH, mwuahh hah hah!!

My Mom told that loan sharking was illegal, and my Dad told me that contracts with minors were not enforceable. My brother I think borrowed some money from one of his friends (on much more favorable terms), paid me back with one day's interest, and never borrowed money from me again.

I'm not sure how I would use my round-bottom wok on an induction burner, but maybe there's something that would make it work? And how I would char the skin on a chili pepper?

The converter plate is an interesting idea.

Maybe my ideal stove has three induction burners and one gas. Maybe I would discover that I rarely used the gas burner, and decide all induction works fine, and that I could just use my camp stove or outdoor grill if I actually need a flame. A hybrid stove could be a useful approach to getting people to overcome their hesitancy in switching to... (read more)

My ideal stove (which I don't think anyone makes, for various practical reasons) has three burners, one gas, one induction and one electric.

• Induction because induction is interesting, efficient, clean, and works well with ferrous cookware
• Gas because induction doesn't work with some cookware, and sometimes you need an actual flame
• Electric because gas burners suck at low temperature operations -- they get hot spots -- and induction doesn't work with some cookware.

Three burners because that's the most I can effectively use at one time. But maybe having four burners (with a second induction or gas burner) would make sense.

Vague concepts are a...vague concept.

This strategy works for something that happens once, but for something that could be a pattern (e.g. getting ripped off by contractors), allocating thought to it would be worthwhile -- but only if you are focused on learning from the experience, and avoiding this type of problem in the future, as opposed to just wallowing in the fact that you were wronged. (And that's also easier said than done.)
