Reverse thinking is a very important category in design thinking. It is a special form of design thinking and a continuation of logical thinking. The following are the reverse thinking training questions and classic cases I brought to you. I hope you like it!

Reverse thinking training questions 1

Logical thinking (Logical thinking), people understand the process The rational cognitive process that actively reflects objective reality with the help of concepts, judgments, reasoning and other forms of thinking is also called theoretical thinking. It arises and develops as an analysis of cognitive thinking, its structure, and the laws that govern it. Only through logical thinking can people grasp the essence of specific objects and then understand the objective world. It is the advanced stage of human understanding, that is, the stage of rational understanding.

Reverse thinking training questions:

① A believer got craving for cigarettes while praying. He asked the priest present if he could smoke cigarettes while praying. 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't you smoke while smoking?" Can you pray?" The priest replied: "Of course you can." Smoking and praying are the same. Asking to smoke while praying seems to mean disrespecting Jesus; while asking to pray while smoking can mean that you are thinking about God in your leisure time. Grace, of course the priest has no reason to object.

② It is said that the great Russian writer Tolstoy designed such a question: Once upon a time, there was a farmer who left some cows after his death. He wrote in his suicide note: His wife got half of all the cows plus half. The eldest son gets half of the remaining cattle plus half a head, which is exactly half of what the wife gets; the second son gets half of the remaining cattle plus half a head, which is exactly half of what the eldest son gets; the eldest daughter gets the last remaining half. Adding half a head equals exactly half of the cattle received by the second son. As a result, neither a single cow was killed nor left. Ask the farmer how many cows Mr. *** left?

Thinking and answering this question, if you first assume some situations (for example, assuming *** has 20 cows, *** there are 30 cows), and then verify and exclude them one by one, it is naturally possible. But this is somewhat cumbersome, takes a lot of time and energy, and is a stupid method.

The best way to solve this problem is to think and calculate backwards:

Since the eldest daughter got the "half" of the last remaining cow plus "half the head" , as a result, no one was killed, and no one was left, so what she must get is: 1 head.

The second son: The eldest daughter got half the cows of the second son. Then, the second son got twice as many cows as the eldest daughter: 2.

The eldest son: The second son got half the cows of the eldest son. Then, the eldest son got twice as many cows as the second son: 4 cows.

Wife: The eldest son gets half as many cows as his wife, so the wife gets twice as many cows as the eldest son: 8.

Add the number of cows received by the four people: 1 2 4 8 = 15. It can be seen that the farmer left 15 cows.

p>

(b) His answer is yes, then this intersection is a dead end,

(2) Let’s assume: it rains today,

You ask one of them a question ：The sunshine is so beautiful today. This intersection leads to the road to life, right?

　(a) He answered no, then this intersection is the road to life,

Basis: His answer is to give priority to your previous exclamation, so you can determine whether he is telling the truth or a lie

There is another answer:

That is: you ask one of the people: He (the person at another intersection) has been telling lies. This intersection leads to a way out, right?

Some classic cases of reverse thinking

The story of Foolish Old Man who moved mountains is a household name in our country; the spirit of Foolish Old Man who moved mountains has educated generations after generations. Especially when encountering difficulties, many people will think of the story of Yu Gong and firmly believe that as long as they persist to the end like Yu Gong, they will achieve success.

Sixty years pass by in a blink of an eye. Today, our country's economic situation and development tasks have undergone tremendous changes. Does our era still need Yu Gong’s spirit of moving mountains?

Looking at Yu Gong from the current perspective, some people may think this way:

Why doesn’t he “move”? How many members of the family are there? After carrying your luggage and climbing over the mountains, you can reach big cities such as Luoyang, Zhengzhou and Xi'an within a short distance. If you dislike the noisy city, you can still settle in a village with fertile land in the North China Plain;

Why doesn't he find a solution to the problem with the leaders? Two mountains must be blocking his family's way out. Therefore, he can report to the township head or the county head. If you can win national project funding, can you also contract a section of the project?

Some people say that in this way, Yu Gong will no longer be a "Foolish Old Man", let alone a respected and worthy example. . The reason why Foolish Old Man's spirit of moving mountains is valuable is that he thought things that ordinary people dare not think of, did things that ordinary people could not do, and made efforts that ordinary people would find difficult to make. The spirit of Foolish Old Man is still worthy of our study in contemporary times.

To learn from Yu Gong, you must learn from his spirit of “taking the initiative to dig mountains”. In front of us, there are still many "mountains". For example, the backward western regions, grassroots units and industries with more difficult work all need someone to "dig" them. Nowadays, many college graduates take the initiative to be contemporary "foolish old men": they also know that the economic benefits and living conditions in big cities are good, but they still rush to the grassroots, to the west, and to hard places without hesitation. Because they understand that "moving" can change their living environment, but it cannot change the backwardness of difficult areas.

To learn from Yu Gong, we must learn from his spirit of “digging mountains by one’s own efforts”. Foolish Old Man might be able to hand over the heavy responsibility of digging mountains to the leaders, pass it on to the collective, and leave it to future generations. No one would ask an old man who is "90 years old" to complete this "impossible task." But Yu Gong did not do this. He said: "I and you will overcome the danger and point the way to the south of Henan and reach Hanyin, okay?" After unifying the thoughts of his family, he immediately took action, relied on self-reliance and worked hard.

To learn from Yu Gong, you must learn from his spirit of “constantly digging mountains”. It is not difficult for a person to move a stone. What is difficult is to move stones for a lifetime, and children and grandchildren will always move stones. There are many difficulties encountered in the process of digging mountains. For example, problems with eating, dressing, tools, injuries, problems with people gossiping, problems with doing earth-shattering good deeds but not getting rewards, etc. But no matter what problems he encountered, Yu Gong did not waver, but remained determined and kept digging.

The essence of the spirit of Yu Gong Yishan is faith, belief, confidence and hard work. Only with correct beliefs, firm convictions and sufficient confidence can we strive for a great cause throughout our lives. Career success is inseparable from hard work. When we study "The Foolish Old Man Moves the Mountains" today, we should face difficulties like Foolish Old Man, seek truth and be pragmatic, and work hard. With such motivation, there is no difficulty that cannot be overcome and no undertaking that cannot be accomplished.
