Six-degree space theory is a psychological game, not a science.

There is a conjecture in the field of mathematics, called six Degrees of Separation, and Chinese translation includes the following: Http://www.aliyun.com/zixun/aggregation/12932.html "> Six Degrees of Separation theory, Six-degree space theory and small-world theory.

The six-degree space theory points out that there are no more than six people between you and any stranger, that is to say, you can know any stranger by up to six people. This is the six-degree space theory, also known as the Small World theory.

The phenomenon of six degrees of separation is not to say that the relationship between anyone and people must be connected through six levels, but the expression of an important concept: any two unknown people, through a certain way of contact, can always produce an inevitable connection or relationship. Obviously, the opportunities to achieve individual expectations will be significantly different as the contact and communication capabilities differ.

Social network is actually not advanced, its theoretical basis is "six Degrees of separation." Social software is a value-added software and service built on the real social network. There is a story that a few years ago a German newspaper took a challenge to help a Turkish barbecue restaurant owner in Frankfurt to find his Marlon with his favorite movie star. After a few months, the staff of the newspaper found that the two individuals had a personal relationship with no more than six individuals. The original barbecue restaurant owner is an Iraqi immigrant, a friend living in California, just the friend's colleague, is the film "This Man a little color" of the producer's daughter in the sorority's sworn sister boyfriend, and Malone Brando starring in the film.

In 1967, Milgram, a social psychologist at Harvard University, designed a chain-mail experiment in Milgram. He randomly sent a chain of letters to 160 people residing in Omaha, Nebraska State, with the name of a Boston stock broker who asked each recipient to send the letter to a friend they thought was closer to the stockbroker. After receiving the letter, the friend does the processing. Eventually, most of the letters arrived at the stockbroker after six steps. The concept of six-degree space comes from this. This chain experiment embodies a seemingly universal objective law: the socialization of modern human society members, may be through "Six Degrees of space" and linked, absolutely no connection between A and B does not exist.

The six-degree theory is just a psychology game that professors and people play instead of science.

1. The six degree theory is a typical pseudoscience with a push.

What is "with push"? For example, now if all of us think that small A is mentally ill (objectively small A is normal, first wronged little a), then we will find countless small a mental illness place, small a no matter what can be regarded as mental illness.

This way, when we believe we can establish some kind of connection with Obama, we will be desperate to search for evidence and links, the possible link is that when we were five years old and So-and-so have met (after all, and we have met every day countless), and vice versa, this is called relationship?

And the discovery of the six-degree theory is precisely a "social psychology" professor. Six degree theory is not a real science, but a psychological game.

2, six degree theory is a goal-oriented game.

The general process of scientific reasoning is this. Because a so B, but what about the six degree theory? Professor of psychology uses a game in his spare time to roll out B, because it has to B, so people go for a, and a is infinitely possible, which in turn proves B. This is causal inversion. In other words, don't say six people, five people, four people can still find contact, why not four-dimensional space theory, five-degree space theory, seven-degree space theory?
