Paradoxes, effects or mental phenomena intrigue us even when they have a logical explanation. At the moment you encounter feel as if something is interfering with the laws of nature, in normalcy!
Here are some of them:
Baader-Mei nhof phenomenon
The idea is very simple: find a new word or concept and suddenly you will see it appear everywhere. For example, did you learn about Baader-Meinhof? Very well, you will hear and mention everywhere. This is by no means a coincidence and in fact nothing to be surprised. We notice a word (just like an object) when we get to know it. From this moment of glory everywhere.
Illusion "strange face in the mirror"
Italian psychologist Giovanni B. Caputo has studied the illusion that is created as a result of seeing for a few seconds the reflection of the face in the mirror. Some people see their parents, some other different facial versions, and some inhumane creatures.
Jamais vu
"Jamais vu" comes from French and can translate it as "never before", the opposite of deja vu. For example, you know a certain word, I know very well when a beautiful day looks like you are listening for the first time. The easiest way to create a "jamais vu" is to repeat a word several times. You will feel that the word sounds bizarre and makes no sense. Jamais vu and deja vu are still mysteries to scientists.
Effects of Mandela
This effect was named after an ambiguity over Nelson Mandela, who is thought to have died in jail 40 years ago. In fact, he died home in 2013. Of course, there are scientific explanations for this, but some people prefer to believe in the theory of parallel universe or in changing historical facts. Here is another example of the MANDELA effect.
How many people were with Kennedy when he was killed? Most think 4, but not. There were actually 6 people in a six-seat car: the President, the First Lady, the Texas governor, his wife, an unknown man and a driver.
The effect of homogeneity on others outside the group
All members of a group look identical from those of another group. For example, all Asians seem to us alike. This is not about racism but instincts, with the idea: "They are the same, we are different."
Effects of sinesthesia
This happens when the perception of an image with sound effects is related. You can hear the color and look at the aroma. For example, number 3 always picture blue. The cause of confusion of the senses is certainly unknown, some studies say that this effect appears 1 to 2,000 people, and others 1 to 23.
