Assessing the sameness and non-rarity of hipsters

October 30th, 2014

Hipsters are becoming more common, in both major senses of the word common, suggests this study:

touboulThe hipster effect: When anticonformists all look the same,” Jonathan Touboul, arXiv:1410.8001, October 29, 2014.

The author explains:

“In such different domains as statistical physics and spin glasses, neurosciences, social science, economics and finance, large ensemble of interacting individuals taking their decisions either in accordance (mainstream) or against (hipsters) the majority are ubiquitous. Yet, trying hard to be different often ends up in hipsters consistently taking the same decisions, in other words all looking alike. We resolve this apparent paradox studying a canonical model of statistical physics, enriched by incorporating the delays necessary for information to be communicated. We show a generic phase transition in the system: when hipsters are too slow in detecting the trends, they will keep making the same choices and therefore remain correlated as time goes by, while their trend evolves in time as a periodic function. This is true as long as the majority of the population is made of hipsters. Otherwise, hipsters will be, again, largely aligned, towards a constant direction which is imposed by the mainstream choices. Beyond the choice of the best suit to wear this winter, this study may have important implications in understanding dynamics of inhibitory networks of the brain or investment strategies finance, or the understanding of emergent dynamics in social science, domains in which delays of communication and the geometry of the systems are prominent.”

Touboul is, in his own words: Principal Investigator “of the Mathematical Neuroscience Team, part of the Center for Interdisciplinary Research in Biology of the Collège de France. I am researcher at Inria (Paris), in the MYCENAE Team.” He writes, in this paper, in the royal we. He does not explicitly self-identify as a hipster.

Swaggering in the performance of root canal procedures

October 30th, 2014

dr-michael-j-scianambloSwaggering could be of importance when one has to perform a root canal procedure. This patent shows one way to introduce—and guarantee—that swaggering will be part of the fun:

Swaggering endodontic instruments,” US patent 8454361 granted June 4, 2013 to Michael J. Scianamblo [pictured here]. The patent document explains:

Endodontic instruments are described which have at least a section with a center of mass offset from an axis of rotation so that when the instrument is rotated, the section bends away from the axis of rotation.”

Here’s detail from the patent:


Ig Nobel winner David Dunning surveys recent research about incompetent people

October 29th, 2014

Ig Nobel Prize-winning Cornell psychology professor David Dunning — he of the Dunning-Kruger effect — tells the majestic story of incompetent people, in this essay in Pacific Standard:

We Are All Confident Idiots

BY DAVID DUNNING • October 27, 2014 • 4:00 AM

The trouble with ignorance is that it feels so much like expertise. A leading researcher on the psychology of human wrongness sets us straight.

The 2001 Ig Nobel Prize for psychology was awarded to David Dunning and Justin Kruger, for their modest report, “Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments.” [Published in the Journal of Personality and Social Psychology, vol. 77, no. 6, December 1999, pp. 1121-34.]

Here’s a link to a full copy of the prize-winning study.

Here is a curious interview, conducted in the year 2012 by opinionated interviewer George Galloway, with David Dunning. The interviewer, a former politician, keeps asking whether voters are stupid:

Pop music: extant and market taxonomized

October 29th, 2014

Pop music – does it really exist? Yes it does. For a statistical analysis, see: Does pop music exist? Hierarchical structure in phonographic markets by Andrzej Buda of the Uniwesytet Jagielloński w Krakowie, Poland, and reproduced in Physica A: Statistical Mechanics and its Applications, Volume 391, Issue 21, 1 November 2012, Pages 5153–5159

“I find a topological arrangement of assets traded in phonographic markets which has associated a meaningful economic taxonomy.“

Dr. Schwab explains why woodpeckers don’t get headaches

October 28th, 2014

Dr. Ivan Schwab explains why woodpeckers don’t get headaches, in this Discovery Channel video:

He explains it in more detail, in this TEDx Talk:

Dr. Schwab, of the University of California Davis, and the late Philip R.A. May of the University of California Los Angeles, were awarded the 2006 Ig Nobel Prize for ornithology, for exploring and explaining why woodpeckers don’t get headaches.

If you come to the Improbable Research show at the AAAS Annual Meeting, on February 14, 2015, in San Jose, California, you can see and hear and meet Dr. Schwab, and learn the latest on his work.

This video from the University of Southern California (USC) explains how USC researchers are following in the path laid out by Dr. Schwab, to better understand how the woodpecker insights might be applied to protecting the brains of human football players:
