# Simple "racism simulation" to understand the reality that individual prejudice distorts society "parable stories"

ByWoodleywonderworks

A game theorist scholar who won the Nobel prize for economics**Thomas Schelling**"Personnel isolation simulation" advocated by Mr. Miyuki was, for example, "Although white and black people think that there is no resistance to living next to each other", white unidentified people are white and blacks live in black, It explains the reason for the event that "It will be completed." To learn this racism simulation intelligibly and actively learn "**A parable of a polygon**So, you can see what kind of effect "prejudice" will distort society with a little puzzle game sensation.

**Parable of the Polygons - articles you can play about polygonal society**

In the "parable of a polygon", a racial isolation simulation is performed using triangles and squares instead of humans.

For these two shapes, 50% are triangles and the remaining 50% are rectangles. All shapes have a little bit of commitment to shape, but I think that they want diverse companions to be around.

There is no diversity if the surroundings are all the same shape as below. So, I am dissatisfied with my whereabouts triangle ......

When I move to a place where the triangle and the square are moderately mixed, I am satisfied with my whereabouts.

In the "parable of a polygon", you can move a shape that makes your dissatisfied face floating with your drag and drop, like this way your neighbors do not like. Once you are satisfied with the circumstances, the shape can not be moved until your neighbor does not like it again. And, in addition to "

**When my colleagues who have the same shape as myself have become less than one third of the neighbors next door, I will move and look for other strangers.**There is a simple rule of "It is.

In the following cases, the triangle in the middle is dissatisfied, unhappy because there is only one member of the same shape around him. Therefore, I can not help moving out.

In the case of the following placement, all shapes have the same shape as yourself more than 1/3, so that all shapes are satisfied with their place.

And the surroundings are all the same form of yourself. The ideal is "the other shapes are around", but the only rule is "When a group of people who have the same shape as yours is less than one-third of the neighbors next to you, Because I am protected ", shapes will not move.

In other words, we want a state in which all polygons are moderately mixed. However, only prejudice that "neighborhood does not like forms different from myself" exists as an absolute rule.

Next, a board with many triangles and squares shown below appeared. We change the arrangement of shapes by drag & drop so that all shapes on this board do not complain.

Although the results are not uniform, the triangles are always settled in triangles as shown below, and the quadrangle falls into a "racial separated state" which is a rectangle. This did not mean that the shapes did something bad, as the same shapes disappeared from my surroundings, each moved into a neighborhood of the same shape as their own. Where triangles gather, we welcome the rectangle to move to the neighborhood, but there is no longer a single rectangle to come there.

In the simulation below, I am moving to a vacant place randomly by myself, I am dissatisfied with my whereabouts. Repeat this and, when the whole shape is satisfied with your place, how much is the whole race separated?

To start the simulation, click "START MOVIN".

Then, shapes with dissatisfaction with whereabouts began to move and the segregation status is rising. Ultimately, most forms will gather in the same shape as yourself as follows.

Even in a wonderful arrangement where diversity was preserved as below, there is a form that only one person complains about ... ...

In order to satisfy all forms, we must satisfy with neighborhood relations without diversity.

This is what happens because each shape is slightly biased towards preference, so that

**Small prejudice of individuals creates a big bias as society as a whole**It shows that. Then, what happens if the individual prejudice becomes infinitely small or very prejudiced?

The following simulator is a simulator that can adjust with slide bar with prejudice held by shape (the same friend as my friend moves, looking for an outsider if it is less than a percentage of the neighbors next door).

You can change the degree of prejudice by moving this slide bar.

For example, with exactly the same arrangement left, if less than 33% of the neighbors have the same shape as myself, move to "degree of prejudice 33%", if the right is less than 50% of the neighbors the same shape as myself In the case of "50% degree of prejudice" to move if there is not. What kind of arrangement will each shape make up?

The correct answer is as follows. Just a little prejudiced strongly increases the segregation state at once.

So, if everyone has no prejudice, how does the arrangement of the shapes change? However, the world starts from the separation of triangles and rectangles. The answer is "Nobody moves".

From this we can say that "

**If society began from a place where there is even little prejudice, simply eliminating prejudice is not enough**"about it. So, what happens if each form wants to have a little diversity?

For example, "If more than 90% of the neighbors are the same shape as yourself, move it".

When each starts moving, it becomes as follows. Despite the thought that each shape is "90% of the surroundings are the same shape as yourself", the placement of the shapes will change at once with just a little diversity.

If you simulate this with more shapes, please actually try running the simulator to see what happens.

What kind of state each form can tolerate can change greatly by only slightly changing the way of thinking. "The parable of a polygon" is a triangle and a quadrangle to conduct a racial isolation simulation, but this is not limited to "triangle and square" or "racial discrimination". Remember that the big prejudice of the society as a whole is born out of a little prejudice of the individual, if you are creating a situation in which only a small prejudice is in trouble, you may be able to overcome the situation by having the opposite "prejudice" It is important to understand that there is nothing.
