Link: PRISMs, Gom Jabbars, and Consciousness (Peter Watts)

Morsella has gone back to basics. Forget art, symphonies, science. Forget the step-by-step learning of complex tasks. Those may be some of the things we use consciousness for now but that doesn’t mean that’s what it evolved for, any more than the cones in our eyes evolved to give kaleidoscope makers something to do. What’s the primitive, bare-bones, nuts-and-bolts thing that consciousness does once we’ve stripped away all the self-aggrandizing bombast?

Morsella’s answer is delightfully mundane: it mediates conflicting motor commands to the skeletal muscles.

How David Beats Goliath

18 JulianMorrison 05 May 2009 01:25AM

From the New Yorker:

It was as if there were a kind of conspiracy in the basketball world about the way the game ought to be played, and Ranadivé thought that that conspiracy had the effect of widening the gap between good teams and weak teams. Good teams, after all, had players who were tall and could dribble and shoot well; they could crisply execute their carefully prepared plays in their opponent’s end. Why, then, did weak teams play in a way that made it easy for good teams to do the very things that made them so good?

[...]

David’s victory over Goliath, in the Biblical account, is held to be an anomaly. It was not. Davids win all the time. The political scientist Ivan Arreguín-Toft recently looked at every war fought in the past two hundred years between strong and weak combatants. The Goliaths, he found, won in 71.5 per cent of the cases. That is a remarkable fact. Arreguín-Toft was analyzing conflicts in which one side was at least ten times as powerful—in terms of armed might and population—as its opponent, and even in those lopsided contests the underdog won almost a third of the time.

[...] What happened, Arreguín-Toft wondered, when the underdogs likewise acknowledged their weakness and chose an unconventional strategy? He went back and re-analyzed his data. In those cases, David’s winning percentage went from 28.5 to 63.6.

[...]

Arreguín-Toft found the same puzzling pattern. When an underdog fought like David, he usually won. But most of the time underdogs didn’t fight like David. Of the two hundred and two lopsided conflicts in Arreguín-Toft’s database, the underdog chose to go toe to toe with Goliath the conventional way a hundred and fifty-two times—and lost a hundred and nineteen times.

Fix it and tell us what you did

The main danger for LW is that it could become rationalist-porn for daydreamers.

I suggest a pattern of counterattack:

  1. Find a nonrational aspect of your nature that is hindering you right now.

  2. Determine privately to fix it.

  3. Set a short deadline. Do the necessary work.

  4. Write it up on LW at the deadline. Whether or not it worked.

The ideas you're not ready to post

24 JulianMorrison 19 April 2009 09:23PM

I've often had half-finished LW post ideas and crossed them off for a number of reasons, mostly they were too rough or undeveloped and I didn't feel expert enough. Other people might worry their post would be judged harshly, or feel overwhelmed, or worried about topicality, or they just want some community input before adding it.

So: this is a special sort of open thread. Please post your unfinished ideas and sketches for LW posts here as comments, if you would like constructive critique, assistance and checking from people with more expertise, etc. Just pile them in without worrying too much. Ideas can be as short as a single sentence or as long as a finished post. Both subject and presentation are on topic in replies. Bad ideas should be mined for whatever good can be found in them. Good ideas should be poked with challenges to make them stronger. No being nasty!
