Once a person's strengths are magnified, they are often grossly exaggerated and their flaws are ignored. Many people will even "love the house and Wu", as long as they think that someone is good, they will often give her all the good qualities, which is simply a good and a hundred good, and his friends and his family will definitely not be wrong.
One day in 1963, Mpemba found that the hot milk he kept in the freezer of his refrigerator froze before the cold milk of his classmates. This puzzled him, so he immediately ran to ask the teacher for advice. The teacher said easily, "You must be mistaken, Mpamba." Unconvinced, Mpemba conducted another experiment, but the result was that hot milk froze before cold milk.
One day, Dr. Osborn, Head of the Department of Physics at the University of Dar es Salaam, visited Mpemba's school. Mpemba plucked up the courage to ask the doctor his question. Dr. Osborn replied, "I can't answer your question right away, but I promise to do it myself as soon as I get back to Dar es Salaam." As a result, the doctor's experiment was exactly what Mpemba said. As a result, the phenomenon of "hot milk freezes before cold milk" is called the "Mpemba" phenomenon. For more than 40 years, the "Mpemba phenomenon" has been recognized as truth to this day.
It doesn't end there. In 2004, a student at Xiangming Middle School in Shanghai questioned the phenomenon. Under the guidance of Huang Zengxin, a famous science and technology teacher, he and two other girls began to act in the Mpemba phenomenon. They used sugar, water, milk, starch, ice cream and other materials, using advanced multi-point automatic temperature measurement recorders, after recording tens of thousands of data for multi-factor analysis, and finally came to the conclusion that in the case of the same quality and quantity, and the same external environment, it is impossible for hot liquids to freeze before cold liquids, and put forward three possibilities that cause misunderstanding.
Storytelling is not our original intention, and we don't want to argue whether the Mpemba phenomenon exists, but what we want to say is what exists behind the story: why is it that a phenomenon that does not exist has been accepted as truth for more than 40 years without anyone questioning it?
That's where the halo effect comes in. The halo effect, also known as the halo effect, refers to the fact that people have a strong self-perception of a certain character or trait of things, and the impression is relatively deep and prominent, and this feeling is like a halo in the form of a moon halo, diffusing and diffusing to the surroundings, affecting the understanding and judgment of other qualities or characteristics of things.
The reason why people believe in the existence of the Mpemba phenomenon is because of the good impression of experts, and under the influence of this impression, people are convinced of the existence of the Mpemba phenomenon - because this conclusion is given by a physicist, he is a physicist, and the conclusion is definitely correct.
It can be seen that the "halo effect" is a cognitive bias, a tendency to generalize, and it works without people realizing it.
In real life, the halo effect can be seen everywhere. The girl and the young man in love are affected by the halo effect, and both parties will be idealized - the girl becomes a fairy in the world, and the young man becomes a prince charming. At this point, both parties become flawless, and all shortcomings become advantages: a pale face is called "white and flawless", and a slender and thin face is called "slender and well-proportioned". The body is fat, and the black mole on the face is called "beauty mole". No wonder Shakespeare exclaimed: "Lovers and poets are full of imagination." ”
The halo effect is also common in educational activities. When the teacher has a good impression of a student, he will think that the student is good at everything, bragging and saying big things is eloquent, and even if he makes a mistake, he will give the most thorough understanding - how can a person be without fault if he is not a sage!
For example, "a certain military commentator at the National Defense Research Institute analyzed the situation of the Iraq war as follows," "according to a professor of a first-class university," "according to the most authoritative academic journal recognized in the world," and "the general manager does not seem to oppose this plan."
And as soon as most people hear about an authoritative assertion, they immediately abandon their own assertion or belief and turn to the authoritative assertion, so that they are naturally convinced. It's no wonder that some salesmen tend to say when developing members: "The famous xxx family xxx has also joined our club" and so on.
Why is it that commercials are always made by famous personalities and movie stars, rather than by little-known people? Why are the products launched by celebrities more likely to be recognized by everyone? Of course, it's also because of the halo effect.
