Inadvertent confirmation

From The hipster effect: Why anti-conformists always end up looking the same by Emerging Technology from the arXiv. Marginally interesting. The effect has long been known, but now we are trying to model the causal mechanisms. Power laws and tipping points are unaddressed in the article but likely to be significant elements.
This is the hipster effect—the counterintuitive phenomenon in which people who oppose mainstream culture all end up looking the same. Similar effects occur among investors and in other areas of the social sciences.

How does this kind of synchronization occur? Is it inevitable in modern society, and are there ways for people to be genuinely different from the masses?

Today we get some answers thanks to the work of Jonathan Touboul at Brandeis University in Massachusetts. Touboul is a mathematician who studies the way the transmission of information through society influences the behavior of people within it. He focuses in particular on a society composed of conformists who copy the majority and anticonformists, or hipsters, who do the opposite.

And his conclusion is that in a vast range of scenarios, the hipster population always undergoes a kind of phase transition in which members become synchronized with each other in opposing the mainstream. In other words, the hipster effect is the inevitable outcome of the behavior of large numbers of people.

Crucially, Toubol’s model takes into account the time needed for each individual to detect changes in society and to react accordingly. This delay is important. People do not react instantly when a new, highly fashionable pair of shoes becomes available. Instead, the information spreads slowly via fashion websites, word of mouth, and so on. This propagation delay is different for individuals, some of whom may follow fashion blogs religiously while others have no access to them and have to rely on word of mouth.

The question that Touboul investigates is under what circumstances hipsters become synchronized and how this varies as the propagation delay and the proportion of hipsters both change. He does this by creating a computer model that simulates how agents interact when some follow the majority and the rest oppose it.
As I say, somewhat interesting, but early days yet.

What is fun, however, is the meta-irony.

Heh.
