There is also " collective intelligence " that grandmother left for the last 20 years and was unresolved mysterious cryptograms were going to elucidate by explosion on the net, while tragedy happens by collective psychology. The " wisdom or madness of the crowd " that makes it possible to experience such a group psychology visualization, actually experiencing infection of ideas and behaviors from person to person by making the network by oneself is very public It is interesting.

When you access the above URL, this screen will appear, so click on "Play with me!" First.

Isaac Newton who discovered the gravitation pull failed in the speculative boom, and when it lost 4.6 million dollars (about 500 million yen) as the current value, he said "It can not calculate the madness of people." Why does the crowd turn to madness or become smarter like this? The intelligent tool to understand is "wisdom or madness of the crowd". Clicking the button and proceeding ... ...

A screen like this appears and the number at the bottom of the screen has changed to "1". "Wisdom or madness of the crowd" has 7 chapters in all, and you can skip chapters by clicking on the bottom button on the way.

First of all, I will experience the "What is a network?" When drawing a line with a cursor between the face of a person and the face, a relationship was born between the two people ......

Conversely, if you scratch the already written line, the relationship will be broken. Click "Go on next".

People regard their own familiar connection as it is the world. For example, drinkers on the upper right considers "50% of the world's heavy drinkers" because they have friendship with two people in total, "one who does not drink" and "one who drinks." .

However, when breaking the relationship of one who does not drink, only a relationship of friendship with "one who drinks" disappears, and it seems that it is "100% of the brewery that occupies the world".

When we enter into friendship relationship as below, we regard each as "50% of the world's largest drinkers". ... and so we can simulate crowd psychology like this. Click "Oh, I understand," I understand.

With such a feeling, supplementary explanation will appear in the gray frame. When I click it ......

An explanation about James Sulwicky 's "Everybody's opinion is unexpectedly correct " that appeared about crowd psychology appeared.

Also, when you click the reference link ... ....

A link to the research paper on which the claim is based appears, so if you wish to know more, it would be OK.

Pressing "Everyone Duma" ... ...

Rushed into the stage where you can actually experience group creativity in puzzle form. Task is to join in a relationship in such a way that it recognizes that "50% of friends are liquor" in nine groups of three drinkers and six drinkers.

In other words, as long as the network consists of "only one friend has a single sake brewery" or "one of the two friends has a liquor store", that person's world recognition is "most of the friends are brews" That's it. When drawing a line and drawing it, the letter "correct answer" appeared. If you press "... You are welcome?" And ...

This time about the collective psychology "infection". Because a different picture will appear, just press the button "simulation" for the time being.

Then, starting from the leftmost person, a state in which one thing spreads out in an instant was automatically reproduced. This is "infection".

Everything such as smoking, health, happiness, supporting party and so on applies to this "one thing", it seems that even suicide and shooting incident will be infected. "That is sad" Click.

It is possible to experience this infection by creating a network on its own. Groups that are divided into four are displayed so that you can "infect" by drawing lines between them to create friendships.

I will draw a line in the same way as before. In addition, you can not cut thick lines originally drawn.

If this is OK, click "Simulation". You can actually see if "infection" occurs or does not occur.

Also, a thing called "complicated infection" is set as a threshold which was a simple infection and "it is" puzzle that "most friends are liquor master" and people think. Clicking "Simulation" ...

With this feeling, the infection stopped on the way. This is because the threshold value is 50%, some people "who are three out of three people", that is, 33% infection came out on the way. Click "... ... of the crowd, wisdom?"

Take a volunteer as an example and experience complex infections. What kind of friendship relationship should we connect to make all six people volunteer with "lightly colored people participating in volunteer" as the starting point? It is a problem. In addition, the threshold is 25%, that is, it is OK if everyone is in a state of "volunteering is performed by at least 4 people in friendship relationship".

If you add lines like this, the proportion of each infection will change. By also clicking on the simulation at the end, you can check the correct / incorrect answer.

The figure displayed as "Simple Infection" will be displayed again. However, even if you draw a line just like a simple infection, you can not infect everyone well. In case of complicated infection, it seems that you can not infect well only by having friendship with one of the different groups.

You can see that infection spreads as more people have friendships.

In addition to this, "experience how to connect a network that infection does not spread to all" ...

As an example of " group weakness " in which the group is too close and not functioning well ......

There was also a puzzle that "the concept diffuses, making groups not shallowable, just making a good group."

The last problem was a puzzle that creates a connection between the group and the group so that the concept spreads throughout the crowd.
