Note: this book being also very comprehensive, I am publishing its summary in two parts. This is Part Two. Part One is here.

Chapter 5: Emotion
“If I look at the mass, I will never act. If I look at the one, I will.”
Mother Theresa
Scientific research shows that Mother Theresa’s precept is true for most of us. Charity organizations have known this for a long time: we do not give to “poverty in Africa”, but we sponsor this or that child. It is very difficult for us to feel compassion for statistics. Although we are aware that the economical situation in Africa is dreadful, we often do not feel concerned enough to act. Seeing an individual suffer, and knowing that we can do something to soothe their ordeal, is quite different.
Charity organizations are not the only ones needing to make people feel concerned. Managers, teachers, politicians and many others need to motivate their colleagues, their pupils, their troops.
What should you be looking for in order to motivate human beings? Appeal to what matters to them. And what matters to them? What are they concerned about?
The answer is simple: themselves. You therefore need to appeal to… their personal interest, and explain: “what can you gain from it” in the messages and ideas you want to convey. How many teachers have heard their pupils ask “But what’s the point of it?”. Do you think pupils are motivated to learn if their teacher cannot answer this question? And what if we could tell them that algebra improves your video game performances, would a teacher hesitate to say it? Would any teacher doubt that it would make the pupils more attentive?
If you have their personal interest on your side, don’t hesitate. Don’t beat around the bush. Don’t say: “People will feel safe with GoodYear Tires”, say: “You will feel safe with GoodYear Tires”.
There is however a more subtle way to appeal to the people’s personal interests. In 1982, psychologists carried out a survey on persuasion: students visited homeowners and asked them to answer questionnaires for a presentation. At the time, cable TV was only just beginning and most people had only vaguely heard of it. The survey was meant to compare the efficiency of two different approaches to make people subscribe to cable television, which was to be rolled out a month later.
In the first approach, the following text was presented:
“Cable television will provide its subscribers with more extensive news and entertainment services. Used appropriately, it gives the viewer freedom to plan in order to enjoy the programs on offer. The subscribers may spend more time at home with their family, on their own or with friends, thus saving the hassle of a night out, as well as babysitting and petrol expenses.
In the second approach, the homeowners were asked to imagine a precise scenario:
“Take a few moments and imagine how cable television is going to allow you to enjoy more extensive news and entertainment services. When you know how to use it, you will be able to plan ahead the events you want to watch. Think about it: no more hassle for a night out, not to mention the savings on babysitting and fuel. You will be able to spend time at home, with your family, on your own, or with your friends.”
The differences between the two texts may seem minor. But count the number of times the word you is used in both samples.
One month after the survey, cable television was rolled out in the city and the researchers analyzed the homeowners’ subscriptions. Result: 20% of the first group had subscribed, in keeping with the subscription rate in the area; on the other hand, in the second group, 47% of the homeowners had subscribed.
The subtitle of the article the researchers published was “Is imagining making things happen”. The answer was: it is.
The benefit to the buyer here was not indeed all this valuable. The main argument was: “by subscribing to cable TV, you save yourself the hassle of getting out of your house” (!). These results suggest that – more so than their importance – it is in fact the tangible and concrete aspect of the benefit that clearly comes out when people imagine them, which make them feel concerned.
There is indeed no need to promise the earth: it is often enough to promise reasonable benefits people can easily imagine themselves enjoying.
Personal interest, however, does not explain everything, as Abraham Maslow attempted to demonstrate in his famous pyramid. A recent study presented the following scenario to a selection of people:
Imagine a company offering its employees a $1,000 bonus should they achieve a number of objectives. Here are three ways of presenting the bonus to the staff:
