In addition to modifying the perceived beauty or distastefulness of a given concept, there are knobs you can turn related to the concepts themselves: nudging, splitting, merging, or even destroying (and assigning all remaining aesthetic value to other, related concepts.

Comment by dspeyer on Rationalist Seder: A Story of War · 2017-06-04T21:43:55.027Z · score: 2 (2 votes) · LW · GW

The idea of rationalist seder is to -- carefully! -- use the effect described in "beware fictional evidence" to promote ideas to our awareness.

We know that "the obviously better thing wouldn't be a Nash equilibrium" traps exist, but we have trouble seeing them, and keep seeing malice and power where there is only desperation. We know that stories can give structure to societies (or, at least, we do if we've read Haidt), but we have trouble seeing it, instead seeing madness and gullibility. We know social structures have both costs and benefits which are difficult to weigh against each other, but tend to see only the side that is effecting us right now.

So I wrote this story, this obviously not true story, stripped to its barest bones, so that it could stick in our heads. So that when we should be noticing the things from the preceding paragraph, a spark of recognition fires in our brains and we generate the hypothesis. Once the hypothesis is generated, we can evaluate it with all the tools at our disposal, and this story will (hopefully) get out of the way.

Two small notes for those who aren't immersed in Judaism:

The "almost has been said" refers to the saying:

Keep two truths in your pocket and take them out according to the need of the moment. Let one be “For my sake the world was created.” And the other: “I am dust and ashes.”

credited to Rabbi Simcha Bunam, a leader of the chassidic movement in the early 19th century. He said, rather than wrote, this, so the exact phrasing may have gotten cleaned up by successive quoters (of which there have been many).

As for the rhythm of dayenu and lo dayenu, that's in the traditional melody (which is itself of uncertain origin, but probably a few centuries old at least). Traditionally, the extra beats are filled in by singing "day-dayenu, day-dayenu, day-dayenu, dayenu, dayenu". Almost as if the melody wanted "lo"s in front of half of the dayenus...

Reverse causation is not ruled out because diagnosis can be delayed.

It seems entirely plausible to me that it takes several months of worsening depression symptoms (during which time sex drive is effected) before a patient sees a psychiatrist.

I suppose it's ruled out if we separate "depression" and "diagnosed with depression" into separate nodes, but that doesn't rule out anything interesting.

I think the common thread in a lot of these [horrible] relationships is people who have managed to go through their entire lives without realizing that “Person did Thing, which caused me to be upset” is not the same thing as “Person did something wrong”, much less “I have a right to forbid Person from ever doing Thing again”.

I agree.

The model I use to derive that involves looking at lots of dying people who don't want to die. If we had lots of people lying around saying "I wish I could die; why can't I die?" that same model would conclude the lifespan is too long.

Chronology is evidence of causality, but it's weak evidence. In this case, there are (at least) two problems. First, there could be some other factor (disruption of social network? increase in pro-inflamatory microbiota?) which causes both, but the sex is caused faster. Alternatively, it could be that depression causes low sex drive, but that kicks in immediately whereas it takes months to get a depression diagnosis.

There are good ways to determine causality from observational data, but timing isn't one of them.

Then the most important question for any model would be what domains it's good at.

For example: one model approximates the population as infinite, so it gets decent predictions when the number of agents in each category exceeds five (this is rare).

These requirements to apply the model should be the first thing taught about the model.

That’s the sort of thing he cares about. The trouble about argument is that it moves the whole struggle onto the Enemy’s own ground.

As a general rule, 90% of the execution time of your program will be spent in 10% of its code. Profilers are tools that help you identify the 10% of hot spots that constrain the speed of your program. This is a good thing for making it faster.

But in the Unix tradition, profilers have a far more important function. They enable you not to optimize the other 90%! This is good, and not just because it saves you work. The really valuable effect is that not optimizing that 90% holds down global complexity and reduces bugs.

This advice can backfire. If you're applying it and I'm trying to say something you didn't expect, I'm going to get very frustrated -- trying phrasing after phrasing until you hear what I'm actually saying (or I'll walk away).

Better, to Death:

For once, Death appeared not to smile.

He brought his hand down on the strings.

There was no sound.

There was, instead, a cessation of sound, the end of a noise which Susan realized she'd been hearing all along. All the time. All her life. A kind of sound you never notice until it stops . . .

The strings were still.

There are millions of chords. There are millions of numbers. And everyone forgets the one that is a zero. But without the zero, numbers are just arithmetic. Without the empty chord, music is just noise.

Death played the empty chord.

The beat slowed. And began to weaken. The universe spun on, every atom of it. But soon the whirling would end and the dancers would look around and wonder what to do next.

It's not time for THAT! Play something else!
