Billionaire investor George Soros, who is also Chairman of Soros Fund Management and author of The Crash of 2008, is well known for his theory on reflexivity, which broadly covers political, social, financial, and economic systems. Soros built upon this concept (see also Soros Super Bubble), which was influenced by philosopher Karl Popper. With all the fear and greed rippling through global geographies as diverse as Iceland, California, Dubai, and Greece, now is an ideal time to visit Soros’s famous reflexivity theory, which may allow us to put the recent chaos in context. With the recent swoon in the market, despite domestic indicators trending positively, a fair question to ask is whether the dog is wagging the tail or the tail wagging the dog?

The Definition of Reflexivity

Simply stated, reflexivity can be explained as the circular relationship that exists between cause and effect. Modern financial theory teaches you these lessons: 1) Financial markets are efficient; 2) Information flows freely; 3) Investors make rational decisions; and 4) Markets eventually migrate towards equilibrium. Reflexivity challenges these premises with the claims that people make irrational and biased decisions with incomplete information, while the markets trend toward disequilibrium, evidenced by repeated boom and bust cycles.

Let’s use the housing market as an example of reflexivity. By looking at the housing bubble in the U.S., we can shed some light on the theory of reflexivity. Americans initial buying love affair with homes pushed prices of houses up, which led to higher valuations of loans on the books of banks, which allowed the banks to lend more money to buyers, which meant more home buying and pushed prices up even higher. To make matters worse, even the government joined the game by adding incentives for people who could not afford homes. As you can see, the actions and decisions of an observer can have a direct impact on other observers and the system itself, thereby creating a spiraling upward (or downward) effect.
