Pseudoscience, mainly because it uses us to control it. Since 2008, our laboratory has conducted a series of investigations and studies on the reflective phenomenon of clothes hangers. In fact, there are only a dozen papers on the reflection of clothes hangers in the world, and almost all of them come from this unusual laboratory. Why does the hanger pullover turn? This is also the first problem to be solved in our laboratory. Some people think that this is because the weight of the hanger is uneven, and the head will involuntarily tilt to one side with a hook.

Others think that pain stimulates people's instinct to seek advantages and avoid disadvantages, and tries to reduce stress by turning around. From a scientific point of view, the laboratory has designed a pressure sensor, which can be enclosed in a complete circle to test the pressure of different parts of the head when using a hanger pullover. It is found that no matter which direction the hook faces, when the head turns left, there are two pressure peaks in the left frontotemporal region of the left anterior region of the head and the right occipital temporal region of the right posterior region.

When the head turns to the right, two pressure peaks appear in the right frontotemporal region and the left occipital temporal region of the right anterior region of the head. However, the extra small peak is the weight of the hook itself. From the test results, the influence can not change the head steering, and the simplified model eliminates the influence of the weight of the hook. After a series of studies, our laboratory believes that in order to meet the reflection conditions of clothes hangers, a person's head should first grow into an ellipse.

This also explains why in the first experiment of Christensen 199 1, a woman's experiment failed, because the head of the prop he used in the experiment was too round, but in fact, because hair and skin would hinder the automatic rotation of the clothes rack, when our scalp sensed the friction generated by the clothes rack, it would have the illusion of imbalance, and we wanted to keep this balance by rotating. At this point, the hanger reflection naturally occurs.
