Quora user Marc Ettlinger recently sent me a paper by Sherri Novis-Livengood, Richard White, and Patrick CM Wong entitled Fractal complexity (1/f power law) determines the stability of music perception, emotion, and memory in a repeated exposure paradigm. (The paper isn’t on the open web, but here’s a poster-length version.) The authors think that fractals explain our music preferences. Specifically, they find that note durations, pitch intervals, phrase lengths and other quantifiable musical parameters tend to follow a power law distribution. Power-law distributions have the nifty property of scale invariance, meaning that patterns in such entities resemble themselves at different scales. Music is full of fractals, and the more fractal-filled it is, the more we like it.
The more I learn about biology, the less I believe in free will.
All of our behavior results from a bunch of molecules bouncing around according to the laws of quantum mechanics. Seen that way, we don’t have any more free will than pebbles being tumbled down a river. We think we have free will because we can’t predict the future, and because our immediate experience is full of so much ambiguity.
