No one enjoys the moment. You are stuck at the back of a queue and as those in other lines move ahead and get served, the time to decide arrives. 1.
This question has now been solved by researchers at Harvard Business School. According to what they have found in a new study, they suggest people think twice before switching queues.
The research was led by Ryan Buell, an expert in service management. He looked into consumer queuing behavior after working with economists on what is known as “last-place aversion,” the discomfort people feel when they know they earn less than others or consider themselves at the bottom of the social pile for some other reason. As a result of this aversion to being the last, when a person finds himself at the end of a queue, he can make decisions that he will later regret.
Buell began by observing people at a multi-checkout grocery store and then set up an online survey. People who took part in the survey were told it would take about five minutes. In reality, it took only one minute, but when participants logged in for the survey, they were forced to wait in a virtual queue displayed on the screen. They started at the back and could wait, switch to a second queue or choose to leave.
2. On average, however, those who switched waited 10 percent longer than if they had stayed put. Those who switched twice ended up waiting 67 percent longer than if they had never moved.
“When we join a queue, we tend to make the most rational choice we can, which means joining the shortest queue. 3. Unfortunately, we can often get it wrong,” said Buell.
4. After that, the aversion fades. The researcher suggests people have a chat with the person in front so that they can pass the time more comfortably until someone else joins behind them. “Remember that the person in front of you was the last until you arrived, so someone will show up if you hang around long enough,” Buell said.
A. If we see a line moving faster, we might switch without having enough extra information.
B. About one in five people grew impatient at the back of the queue and switched to the other line in the hope of speeding things up.
C. Do you hold your nerve and stay put, switch to another line in the hope it moves faster, or give up altogether?
D. Based on his study, Buell says people should think hard about switching queues when they are the last in a line.
E. In an unpublished working paper on the research, Buell notes that people tend to feel unhappiest at the back of a queue for the first 10 seconds or so.
F. Although the number of people behind you has nothing to do with how long you are going to wait, it shapes your behavior.
Freedoms challenge in the Digital Age is a serious topic. We are facing today a strange new world and we are all wondering what we are going to do with it.
Some 2,500 years ago Greece discovered freedom. Before that there was no freedom. There were great civilizations, splendid empires, but no freedom anywhere. Egypt and Babylon were tyrannies, one very powerful man ruling over helpless masses In Greece, in Athens(雅典) a little city in a little country, there were no helpless masses.
And Athenians willingly obeyed the written laws which they themselves passed, and the unwritten, which must be obeyed if free men live together. They must show each other kindness and pity and the many qualities without which life would be very painful unless one chose to live alone in the desert. The Athenians never thought that a man was free if he could do what he wanted A man was free if he was self-controlled. To make yourself obey what you approved was freedom. They were saved from looking at their lives as their own private affair. Each one felt responsible for the welfare of Athens, not because it was forced on him from the outside, but because the city was his pride and his safety. The essential belief of the first free government in the world was liberty for all men who could control themselves and would take responsibility for the state.
But discovering freedom is not like discovering computers. It cannot be discovered once for all. If people do not prize it, and work for it, it will go. Constant watch is its price. Athens changed. It was a change that took place without being noticed though it was of the extreme importance a spiritual change which affected the whole state. It had been the Athenians pride and joy to give to their city That they could get material benefits from her never entered their minds. there had to be a complete change of attitude before they could took at the city as an employer who paid her citizens for doing her work. Now instead of men giving to the state, the state was to give to them. What the people wanted was a government which would provide a comfortable life for them; and with this as the primary object, ideas of freedom and self-reliance and responsibility were neglected to the point of disappearing: Athens was more and more looked on as a cooperative business possessed of great wealth in which all citizens had a right to share
Athens reached the point when the freedom she really wanted was freedom from responsibility
There could be only one result. If men insisted on being free from the burden of self-dependence and responsibility for the common good, they would cease to be free. Responsibility is the price every man must pay for freedom. It is to be had on no other terms. Athens, the Athens of Ancient Greece, refused responsibility; she reached the end of freedom and was never to have it again.
But "the excellent becomes the permanent, Aristotle said. Athens lost freedom forever, but freedom was not lost forever for the world. a great American, James Madison, referred to the capacity of mankind for self-government. No doubt he had not an idea that he was speaking Greek. Athens was not in the farthest background of his mind, but once man has a great and good idea, it is never completely lost. The Digital Age cannot destroy it. Somehow in this or that man s thought such an idea lives though unconsidered by the world of action. One can never be sure that it is not on the point of breaking out into action, only sure that it will do so sometimes

The close relationship between speakers and their speech has led some scholars to suggest that language determines the view we have of the world around us. Different languages segment natural phenomena differently. We name seven colors in the rainbow: violet, indigo, blue, green, yellow, orange and red. Speakers of other languages may see only four, as did Turkish before our system was introduced, or even as few as two, roughly the lighter shades versus the darker. There is nothing in nature to demonstrate how we should chop up the spectrum of the rainbow, but when we have learned a given language, we distinguish the shades it designates, both in the rainbow and elsewhere students of language assume from such a situation that language determines much of the and patterns we see in the world around us, and that it directs our concepts and actions
Changes in the choice of language, then, might modify behavior. Today gasoline trucks are generally labeled" flammable(易燃的)". The in-prefix was taken as equivalent to that of words like "inactive", where in- means not". It is actually the in- of words like "intense", where it strengthens the meaning. The word "inflammable", then, means "highly flammable" The faulty interpretation of language, however, determined the attitudes of many speakers, who then adjusted their behavior in relation to the language. Prudent truck owners have taken notice and changed the warning to“ flammable"
Such observations led Whorf to a concept with deeper patterns of language, such as the use of tenses in the language of Europe. Tense is the linguistic expression or time. English and other European languages generally require their speakers to identify the time of an event, whether present: It is raining; past: It rained; or future: It will rain. By contrast, many languages, such as the Hopi language of New Mexico, lack expression for tense. Nor do such languages objectify time. In Hopi one cannot count days, minutes, years as though they were objects like stones. Everyday expressions like "Three years went by" are impossible in Hopi.
Comparing such languages, Whorf proposed that "our use of tense or our objectified view of time is favorable to historicity se t)and to everything connected with the keeping of records." That is to say, because of the patterns for referring to time in English and other languages, their speakers maintain records and emphasize bookkeeping, accounting, and the like. In accordance with it, ones conception of the world is relative to the language one learns
While the relativity hypothesis(假设) has attracted considerable attention, it has never been experimentally demonstrated to the valid. a large scale attempt to test the outlook of Hopi-speaking children versus English speaking children turned out to be inconclusive. It remains a task of future scholars to determine whether the hypothesis is valid and also whether one should assume a weak or strong position with regard to it. Clearly we are deeply tied to our native language. But whether it regulates our perceptions or our view of the world Is still an open question
