Marginal Revolution: Sex and Statistics or Heteroscedasticity is Hot

Alex Tabarrok mulls over the recent OkTrends post on the Mathematics of Beauty.

I think there are certain types of beauty that greatly attract some men but repel others. Analagously, some people will pay hundreds of dollars for an ounce of caviar that other people won’t eat for free. The reason some people love caviar, however, is not that other people dislike it. Instead, it just so happens, that the thing that some people love is the very thing that repels others. We see the same phenomena in art, some people love John Cage, other people would rather listen to nothing at all. ;)

Now if we mix in this kind of beauty–beauty over which there are violent disagreements–with the kind that most people do agree upon (think Haagan-Dazs vanilla ice cream) then I suspect that it will appear that lower rankings increase messages. But what is really going on is that high rankings–conditional on their also being many low rankings–actually signal an extra strong attraction. Someone who tells you that John Cage is their favorite composer is telling you more than someone who says Aaron Copland is their favorite composer.

2010 Review of Books (Aaron Swartz’s Raw Thought)

I frequently hear music in the very heart of the noise…

George Gershwin on Rhapsody in Blue’s inspiration, the rhythm of the city train. (via adamnorwood)

This reminds me of what I called and still call one of my favorite pieces of music ever, Steve Reich’s City Life, which uses a bunch of samples from New York City street scenes: hawkers, sirens, car and boat horns, screeching tires, subway whooshings. Luckily all five parts are online for your listening pleasure.

Black Swan And Bathrooms – Mirror: Motion Picture Commentary

Interesting essay on self and Black Swan. (via)

Solitude welcomes a self or selves that does not, cannot, appear when in the company of others. Private selves refuse to manifest in public because other personas are at the front lines. Like mother Elephants circling their calves, our public selves form ranks. Each is a layer of armor, tweaking our interactions in the unconscious name of self defense.
