Reverse thinking training questions 1
Logical thinking, also known as theoretical thinking, is a rational cognitive process in which people actively reflect objective reality with the help of concepts, judgments, reasoning and other forms of thinking. It comes into being and develops as an analysis of cognitive thinking, its structure and behavior law. Only through logical thinking can people grasp the essential provisions of specific objects and then understand the objective world. It is the advanced stage of human cognition, that is, the stage of rational cognition.
Reverse thinking training problem:
1. A believer is addicted to cigarettes while praying. He asked the priest if he could smoke during prayer. The priest replied "No". Another believer also wanted to smoke, but he asked in a different way and got permission from the priest. Do you know how he asked?
He asked the priest, "Can you pray while smoking?" The priest replied, "Of course." The same is true of smoking and praying. Asking for smoking during prayer seems to mean disrespect for Jesus. Asking for prayer while smoking may mean thinking about God's grace in his leisure time, and the priest certainly has no reason to object.
It is said that Tolstoy, a great Russian writer, designed such a problem: once upon a time, there was a farmer who left several cows after his death. He wrote in his suicide note: His wife got half and half heads of all cows; The eldest son gets half and a half of the remaining cows, which is exactly half of his wife's income; The second son wants to return the remaining half of the cattle and half of the head, which is exactly half of the eldest son; The eldest daughter adds half a head to the last remaining half, which is exactly equal to half of the cattle earned by the second son. As a result, no cattle were killed, and there was nothing left. How many cows does the farmer always leave behind?
Thinking and solving this problem, if we first assume some situations (for example, assuming that * * * has 20 cows and * * * has 30 cows), then we can verify and eliminate them one by one. But it is a bit cumbersome, consumes a lot of time and energy, and it is a stupid method.
The best way to solve this problem is to think backwards and calculate backwards:
Because the eldest daughter got the "half" and "half" of the last remaining cow, she didn't kill 1, and there was nothing left, so she had to get: 1.
Second son: The eldest daughter gets half as many cows as the second son, so the second son gets twice as many cows as the eldest daughter: two cows.
Eldest son: The second son gets half as many cows as the eldest son, so the eldest son gets twice as many cows as the second son: four cows.
Wife: The eldest son gets half as many cows as the wife, so the wife gets twice as many cows as the eldest son: eight cows.
The number of cows obtained by four people adds up: 1+2+4+8= 15. It can be seen that the number of cows left by farmers is 15.

Reverse thinking training problem 2
Suppose you are a survivor, and now you face a fork in the road leading to life and death.
Now, soldier A and soldier B are standing at the intersection respectively.
1. A soldier and B soldier know the direction of life and death, but you don't.
One of the two soldiers always tells the truth, while the other always lies.
Both soldiers know who is telling the truth and who is lying, but you don't.
Question:
You have only one choice now, choose a soldier and ask a question, from which you can decide which way to escape to survive.
Please say you have your problem (only one chance! )
There is a premise that you must know the weather at this time, right!
(1) Let's assume that it didn't rain today.
You ask one of them: it's really raining today. This intersection leads to life, right?
(a) If he answers no, then his intersection is a chance to live.
(b) If his answer is yes, then his intersection is a dead end.
Let's assume that it will rain today.
You ask one of them: the sunshine is really good today. This intersection leads to life, right?
(a) If he answers no, then his intersection is a chance to live.
(b) If his answer is yes, then his intersection is a dead end.
Basis: His answer is mainly based on the exclamatory sentence in front of you, so you can draw the conclusion that what he said is true or false.
There is another answer:
That is: you ask one of them: he (the person at the other intersection) has been telling lies, and this intersection leads to life, right?
Some classic cases of reverse thinking
The story of Gong Yu moving mountains is a household name in China. The spirit of Yugong Yishan has educated generation after generation. Especially when encountering difficulties, many people will think of the story of Yu Gong, and firmly believe that as long as they stick to the end like Yu Gong, they will succeed.
60 years is fleeting. Today, great changes have taken place in China's economic situation and development tasks. Do we still need the spirit of "foolish old man and one mountain" in our times?
Looking at Yu Gong from the present point of view, some people may think like this:
Why didn't he "move" a few people to carry luggage, climb mountains and mountains, and not far away, he could reach Luoyang, Zhengzhou and Xi 'an. If the city is too noisy, you can also settle in a rich village in the North China Plain.
Why didn't he ask the leader to solve it? Two big mountains must have blocked his way out. So, he can report to the township head and county magistrate. If we can get the national project funds, we can also package the next project.
It is also said that in this way, Yu Gong is not a "Yu Gong", let alone a respected example worth learning. Gong Yu's spirit of moving mountains is valuable because he thinks what ordinary people dare not think, does what ordinary people can't do, and makes efforts that ordinary people can't pay. The spirit of foolish old man is still worth learning in contemporary times.
To learn from Yu Gong, we must learn from his spirit of "actively pioneering". There are many mountains in front of us. For example, the backward western region, grass-roots units and hard industries all need someone to "dig". Nowadays, many college graduates take the initiative to be "fools": they also know that big cities have high economic benefits and good living conditions, but they still rush to the grassroots, the west and hard places without hesitation. Because they understand that "moving" can change their living environment, but it can't change the backward appearance of hard areas.
To learn from Yu Gong, we must learn from his spirit of "starting a mountain by yourself". Gong Yu may be able to give the leadership, the collective and future generations the responsibility of starting a mountain. No one will ask a 90-year-old man to complete this "impossible task". But Yu Gong didn't do it. He said, "I will try my best to cross the south of Henan and reach Hanyin, okay?" And after unifying the family's thoughts, they immediately put into action, self-reliance and hard struggle.
To learn from Yu Gong, we must learn from his spirit of "constantly pioneering". It is not difficult for a person to move a stone, but it is difficult to move a stone all his life, and future generations will always move a stone. There will be many difficulties in the process of mountain opening. For example, eating, dressing, tools, getting hurt, gossiping, doing earth-shattering good deeds without asking for anything in return and so on. However, no matter what problems encountered, Gong Yu did not waver, but was determined to dig mountains.
The essence of Gong Yu's spirit of moving mountains is faith, faith, confidence and hard work. Only with correct belief, firm belief and sufficient confidence can we fight for the great cause for life. The success of a career is inseparable from hard work. Today, we should face difficulties, seek truth from facts and work hard like Yugong when studying Yi Mountain. With such momentum, there will be no insurmountable difficulties and no impossible career.
Gary. Shaq is an old man of Jewish descent. After retirement, he bought a humble house near the school. The first few weeks were quiet, and soon three young people started kicking trash cans nearby for fun.
The old man couldn't stand the noise and went out to negotiate with the young man. "You had a good time." He said, "I like watching you have such a good time. If you come to kick the trash can every day, I will give each of you a dollar every day. "
The three young people were very happy and worked harder to perform Step Down. Unexpectedly, three days later, the old man said sadly, "inflation has reduced my income." From tomorrow on, I can only give you fifty cents each. "
The young man looked unhappy, but he accepted the old man's condition. They continue to kick the trash can every day. A week later, the old man said to them, "I haven't received a pension check recently." Sorry, I can only give 20 cents a day. " "Twenty cents?" A young man turned blue. "We won't waste precious time performing here for just 20 cents. Let's quit! "
Since then, the old man has lived a quiet life.
One day, Jewish millionaire Harder walked into the loan department of Citibank in new york. Seeing that this gentleman is very proud and luxuriously dressed, the manager of the loan department dare not neglect him, so he quickly said hello:
"What can I do for this gentleman?"
"Oh, I want to borrow some money."
"Ok, how much do you want to borrow?"
"1 USD."
"Only $65438 +0?"
"Yes, just borrow 1 USD, ok?"
"Of course, a gentleman like you can borrow more as long as there is a guarantee."
"How about these guarantees?"
The Jew said, and took out many jewels from the luxurious leather bag and piled them on the table.
"Well, this is a jewel worth $500,000. Is this enough? "
"Of course, of course! But all you have to do is borrow $65438 +0? "
"yes." The Jews received 1 dollar and were ready to leave the bank.
The president of the branch watching from the sidelines is a little silly at this time. He couldn't figure out why Jews borrowed 1 dollar with a mortgage of $500,000. He hurried up to the Jew and said, "Sir, please wait a moment. You have jewels worth half a million dollars. Why only borrowed 1 USD? If you want to borrow $300,000 or $400,000, we will also consider it. "
"Ah, the thing is this: before I came to your bank, I asked several vaults, and the rent of their safes was very expensive. And your rent here is very cheap, only 6 cents a year. "
The family decided to move into the city and look for a house.
There are three people in the family, two couples and a five-year-old child. They ran all day, until at night, they finally saw an advertisement for serviced apartment.
They hurried to the house, which was unexpected. So, I knocked on the door to ask.
At this time, the gentle landlord came out and looked at the three guests from top to bottom.
The husband summoned up his courage late and asked, "Is this house for rent?"
The landlord said regretfully, "Oh, I'm really sorry, but we don't recruit tenants with children in our apartment."
The husband and wife didn't know what to do at the moment and walked away silently.
The five-year-old child saw the whole story from beginning to end. That lovely heart is thinking: Is there really no way out? His little red hand knocked on the landlord's door again.
At this time, the husband and wife have walked out of 5 meters and looked back.
The door opened and the landlord came out again. The child said happily, "Grandpa, I rented this house. I have no children, I only brought two adults. "
The landlord laughed and decided to rent the house to them.
