In 2003, British Airways made an announcement that they would no longer be able to operate the London to New York Concorde flight twice a day because it was starting to prove uneconomical. Well, the sales for the flight on this route increased the very next day. There was nothing that changed about the route or the service offered by the airlines. Merely because it became a scarce resource, the demand for it increased. If you are interested in persuading people, then the principle of scarcity can be effectively used. If you are a salesperson trying to increase the sales of a certain product, then you must not merely point out the benefits the customer can derive from the said product, but also point out its uniqueness and what they will miss out on if they don't purchase the product soon. In selling, you should keep in mind that the more limited something is, the more desirable it becomes.

The most dangerous threat to our ability to concentrate is not that we use our smartphone during working hours, but that we use it too irregularly. By checking our emails every now and then on the computer and our text messages here and there on our phone with no particular schedule or rhythm in mind, our brain loses its ability to effectively filter. The solution is to regulate your devices as if you were on a strict diet. When it comes to nutrition, sticking to a fixed time plan for breakfast, lunch, and dinner allows your metabolism to adjust, thereby causing less hunger during the in-between phases. Your belly will start to rumble around 12:30 p.m. each day, but that's okay because that's a good time to eat lunch. If something unexpected happens, you can add a snack every now and then to get fresh energy, but your metabolism will remain under control. It's the same with our brain when you put it on a "media diet."

Who is this person? This is the question all stories ask. It emerges first at the ignition point. When the initial change strikes, the protagonist overreacts or behaves in an otherwise unexpected way. We sit up, suddenly attentive. Who is this person who behaves like this? The question then re-emerges every time the protagonist is challenged by the plot and compelled to make a choice. Everywhere in the narrative that the question is present, the reader or viewer will likely be engaged. Where the question is absent, and the events of drama move out of its narrative beam, they are at risk of becoming detached ― perhaps even bored. If there's a single secret to storytelling then I believe it's this. Who is this person? Or, from the perspective of the character, Who am I? It's the definition of drama. It is its electricity, its heartbeat, its fire.

Shutter speed refers to the speed of a camera shutter. In behavior profiling, it refers to the speed of the eyelid. When we blink, we reveal more than just blink rate. Changes in the speed of the eyelid can indicate important information; shutter speed is a measurement of fear. Think of an animal that has a reputation for being fearful. A Chihuahua might come to mind. In mammals, because of evolution, our eyelids will speed up to minimize the amount of time that we can't see an approaching predator. The greater the degree of fear an animal is experiencing, the more the animal is concerned with an approaching predator. In an attempt to keep the eyes open as much as possible, the eyelids involuntarily speed up. Speed, when it comes to behavior, almost always equals fear. In humans, if we experience fear about something, our eyelids will do the same thing as the Chihuahua; they will close and open more quickly.

The free market has liberated people in a way that Marxism never could. What is more, as A. O. Hirschman, the Harvard economic historian, showed in his classic study The Passions and the Interests, the market was seen by Enlightenment thinkers Adam Smith, David Hume, and Montesquieu as a powerful solution to one of humanity's greatest traditional weaknesses: violence. When two nations meet, said Montesquieu, they can do one of two things: they can wage war or they can trade. If they wage war, both are likely to lose in the long run. If they trade, both will gain. That, of course, was the logic behind the establishment of the European Union: to lock together the destinies of its nations, especially France and Germany, in such a way that they would have an overwhelming interest not to wage war again as they had done to such devastating cost in the first half of the twentieth century.

John Bowlby, British developmental psychologist and psychiatrist, was born in 1907, to an upper-middle-class family. His father, who was a member of the King's medical staff, was often absent. Bowlby was cared for primarily by a nanny and did not spend much time with his mother, as was customary at that time for his class. Bowlby was sent to a boarding school at the age of seven. He later recalled this as being traumatic to his development. This experience, however, proved to have a large impact on Bowlby, whose work focused on children's development. Following his father's suggestion, Bowlby enrolled at Trinity College, Cambridge to study medicine, but by his third year, he changed his focus to psychology. During the 1950s, Bowlby briefly worked as a mental health consultant for the World Health Organization. His attachment theory has been described as the dominant approach to understanding early social development.
