Common sense brain teaser

1. Is there any common-sense brain teaser that can easily get the wrong answer habitually?

The so-called mindset effect refers to the phenomenon that people are limited by existing information or understanding.

When people work and live in a certain environment, they will form a fixed mode of thinking over time, which will make people accustomed to observing and thinking things from a fixed angle and accepting things in a fixed way. Here are six small questions about the mind set test. You might as well try them.

1. There is a boat parked by the deserted river. This ship can only hold one person. Two people came to the river at the same time, and both of them crossed the river in this boat.

Excuse me: How did they cross the river? There are four apples in the basket, which are divided equally by four children. Finally, there is an apple in the basket.

Excuse me: how do they divide it? A police chief and an old man are playing chess in the teahouse. Just as it was approaching, a child came running. The child anxiously said to the police chief, "Your father and my father are quarreling."

The old man asked, "Who is this child of yours?" The police chief replied, "It's my son." Excuse me: what is the relationship between these two quarrelling people and the public security bureau chief? 4. A coin has been thrown at random for 9 times, and it will be all right if it falls.

Now let's do it again, assuming that it is not affected by any external factors, what is the probability of the coin facing up? Some people can drink without pulling out the cork. Can you do it? (Note: Do not break the bottle or drill holes in the cork. 6. There are 7 pairs of black and white nylon socks in the drawer. If you take socks in the dark, how many socks do you have to take out to ensure that you can get a pair of socks with the same color? Note that the mind-set test is definitely different from some brain teasers, and it contains certain logical reasoning and mathematical principles.

Please see the following answers and analysis. Answer and analysis: 1, very simple, they are on both sides of the river, one crosses the river first and then the other.

You probably "racked your brains" for this problem, right? Indeed, this ship can only carry one person. If they are on the same river bank and there is no one on the other side, they can't get through anyway. Of course, you may also imagine many ways, such as a person going there first, and then using what method to get the boat back empty, and so on.

But why do you always feel that these two people are on the same side? The title itself does not mean this! It seems that you are still starting from your habits, thus forming a "thinking jam". 2, 4 children, one person.

You may be unconvinced by this answer: didn't you say that four apples were divided equally among four people? What about the rest of the basket? First of all, there is no "left" in the title; Secondly, all three children got their share, and the last share was of course the last child's. What's so strange about this? It makes no difference whether he leaves the apple in the basket or holds it in his hand. Anyway, he got it, didn't he? 3. The police chief is a woman, and it is her husband and the father of the child who quarrels; The other is the father of the public security bureau chief and the grandfather of the child. Someone once tested this question on 100 people, and only two people got it right. Later, I was admitted to a family of three. As a result, the parents guessed for a long time, and the son (primary school student) guessed right.

What's going on here? Still at work. People always associate the police chief with men, not to mention the "teahouse" and "old man" who support this stereotype.

So from the experience, it is not easy to answer. And that pupil is easy to jump out of the fixed "magic circle" because of his lack of experience and experience.

4. Half. This question was originally very simple.

Coins have only two sides, not to mention throwing 10 times at random, that is, throwing 1000 times at random. The possibility of heads up is always half, neither more nor less. For this question, if there is no stereotype like the above picture, you can usually tell the answer immediately.

You can press the cork into the bottle. In most cases, people always open the cork before drinking.

However, you can also press the cork into the bottle, but people don't often do this six or three times. This is also a simple question.

Someone once used this question to test four college students, and three of them actually answered that at least eight pairs of socks must be taken out to ensure that one pair of socks has the same color. The key to this problem is "similarity" and "difference".

Take a pair of the same color, and the answer is 3; Change a pair and the answer is eight. Then, since the question only asks for "the same" color, why is there a stereotype of "different" colors? This is mainly influenced by "black and white nylon stockings" and "7 each" in the title.

Thinking set can make us quite skilled in some activities, even realize automation, which can save a lot of time and energy; However, the existence of mindset will also bind our thinking, so that we only use conventional methods to solve problems without seeking other "shortcuts", which will also bring some negative effects to solving problems. Stereotype effect will be produced not only when thinking and solving problems, but also in the process of understanding and interacting with others.

American popular science writer Asimov once told a story about himself: Asimov was very smart since he was a child. When I was young, I took IQ tests many times, and the total score was around 160, so I was a "very talented person". He has always been proud of it. Once, he met an auto mechanic, an old acquaintance of his.

The repairman said to Asimov, "Hello, doctor! Let me test your intelligence and write a thinking question to see if you can answer correctly. " Asimov nodded in agreement.

The repairman began to think about this question: "there is a deaf and dumb man who wants to buy some nails." He came to the hardware store and made such a gesture to the salesman: two fingers in his left hand stood on the counter and his right hand clenched his fist. " When the salesman saw it, he first brought him a hammer. The deaf-mute shook his head and pointed to two fingers standing.

Then the salesman understood that the deaf-mute wanted to buy nails. The deaf-mute bought a nail and just walked out of the shop when a blind man came in.

The blind man wants to buy a pair of scissors. What do blind people do? Asimov replied smoothly, "Of course the blind will do this." Say, stretch out your index finger and middle finger and make the shape of scissors.

Fix the car.
