6 Shortcuts to Persuasion

The ability to successfully persuade is a powerful skill. Whether you want to be a better sales person or to improve your ability to lead, being persuasive can be key to your success in work and life. At the end of this post, you’ll will find the full infographic which sums up the science of persuasion in graphical form.

Herein, we intend to expand upon six universal principles that are often employed to successfully influence others. These six principles are derived from research done by noted Psychologist Dr Robert Cialdini and others.

Reciprocity

The first shortcut to persuasion is Reciprocity – the obligation people feel to give after they receive something.

This tendency to return a kind gesture or favor is an important principle to remember in order to understand persuasion. As can be seen in an experiment conducted by behavioral scientist David Strohmetz and his colleagues. In the experiment, customers at a diner, after finishing their meal, were given free mints with their bill. The experiment was broken down into three trials:

1. In the first trial, customers were each given a single piece of candy
2. In the second trial, customers were each given two pieces of candy
3. Finally, in the third trial, customers were each given one piece of candy. Then the waiter left the table, however, before the waiter completely left the area, they came back and gave a second piece of candy to each customer. Through this gesture, it was almost like saying “…oh, for you nice people, here is an extra candy each”.

Each trial also included a control group, which were given no candy with their bill. The results from the trials were:

1. For the first trial, the diner noticed 3.3% increase in tips compared to the control group
2. For the second trial, the diner received 14.1% increase in tips compared to the control group
3. For the third and final trial, tips increased by 23% compared to the control group

The experiment concluded that people are more reciprocatory after they received something. Additionally, the way in which they received that something influenced the outcome. Such as in the third trial where customers at the diner tipped more after it appeared the waiter made an exception for them.

Commitment and Consistency

The second of the six shortcuts to persuasion is Commitment and Consistency. People are creatures of habit and live by consistency.

In 1987, an experiment was conducted by social scientist Anthony Greenwald. Greenwald approached potential voters on election-day eve to ask whether they would vote, to which 100% of participants said they would vote. On election day, 86.7% of those asked, casted their vote, compared to 61.5%, who were not asked.

This experiment highlighted that those who publicly committed to vote were more likely to actually vote. This tendency to commit to an agreement is another universal principle of persuasion. Furthermore, when people make a commitment, they are more likely to follow through with an action or decision, in order to remain consistent with those commitments.

Social Proof

People are inclined to look at what others are doing as a basis for taking action or making a decision. This is known as Social Proof and is the third shortcut to persuasion.

An experiment by Dr Cialdini and his colleagues encouraged visitors to an Arizona hotel to reuse their towels. Four types of signs were used to conduct this experiment, each sign encouraged visitors with a different statement:

1. The first sign cited environmental reasons to encourage visitors to reuse their towels
2. The second said the hotel would donate a portion of end-of-year laundry savings to an environmental cause
3. The third sign said the hotel had already given a donation and asked: “Will you please join us?”
4. The fourth and final sign said the majority of guests reused their towels at least once during their stay

At the end of the experiment, the percentage of those who reused towels per request were tallied:
Cialdini Social Proof

The experiment concluded that when guests found out that most people who stayed in the same hotel reused their towels, they were more likely to comply with the request.

Liking

The next shortcut to persuasion is referred to as Liking and the following was extracted from a publication called “Dr. Robert Cialdini and 6 principles of persuasion” by Tom Polanski, EVP at eBrand Media and eBrand Interactive:
“People prefer to say ‘yes’ to those they know and like,” Cialdini says. People are also more likely to favor those who are physically attractive, similar to themselves, or who give them compliments. Even something as ‘random’ as having the same name as your prospects can increase your chances of making a sale.

The article went on to detail a study that was conducted:

In 2005, Randy Garner mailed out surveys to strangers with a request to return them. The request was signed by a person whose name was either similar or dissimilar to the recipient’s. For example, Robert James might receive a survey request from the similarly-named Bob Ames.

According to a study reported in Yes!, “Those who received the survey from someone with a similar-sounding name were nearly twice as likely to fill out and return the packet as those who received the surveys from dissimilar sounding names (56% compared to 30%).”

After the study, the article explained that sales people could improve their chances of making a sale by becoming more knowledgeable about their prospects’ existing preferences.

Authority

The fifth shortcut to persuasion is Authority, people respect and trust authority and often seek the lead of credible experts.

Being in a position of authority or giving the appearance of authority, increases the likelihood that people will comply with a request.

For example, the following was extracted from a 1974 experiment conducted by Stanley Milgram, Psychologist at Yale University:

[an experiment] where ordinary people were asked to shock ‘victims’ when they answered questions incorrectly. Those in charge were dressed in white lab coats to give the appearance of high authority. The participants were told that the shocks they gave increased 15 volts in intensity each time the person answered incorrectly. In fact, the shocks were completely imaginary. Respondents were acting.

As participants continued to shock their victims, the respondents feigned increasing discomfort until they let out agonized screams and demanded to be released. Astoundingly, about two-thirds of participants ignored these cries of pain and inflicted the full dose of 450 volts.

According to Stanley Milgram:
“…the real culprit in the experiments was the [participants’] inability to defy the wishes of the boss, the lab-coated researcher who urged and, if necessary, directed them to perform their duties, despite the emotional and physical mayhem they were causing.”

The experiment showed that people in authority have incredible influence on others and when correctly incorporated, this influence helps persuade others to make a decision.

Scarcity

The final of the six shortcuts to persuasion is Scarcity.

For example, retail stores often offer sales for limited periods, such as for the weekend or on a celebratory day. The scarcity of this opportunity to purchase a product at a discount encourages people to buy.

For example, the following was extracted from the aforementioned publication titled “Dr. Robert Cialdini and 6 principles of persuasion” by Tom Polanski:

In 1985, the Coca-Cola Company made their infamous switch from their traditional formula to the sweeter formula “New Coke.” Their taste tests indicated that 55% preferred the new Coke over the old. Most of those tests were blind, but some participants were told which formula was new and which was the original. Under those conditions, the preference for new Coke increased 6%.

Despite the taste tests, the switch to new Coke triggered incredible backlash against it. Time magazine later dubbed it “the marketing fiasco of the decade.

“The company must have looked at the 6% difference between blind and non-blind preferences and said to themselves ‘Oh, good, this means that when people know that they’re getting something new, their desire for it will shoot up.’”

In fact, what that 6% really meant was that when people know what it is they can’t have, their desire for it will shoot up. Later, when the company replaced the traditional recipe with the new one, it was the old Coke that people couldn’t have, and it became the favorite.

The experiment showed that people are more likely to seize an opportunity if they know that opportunity is limited. Utilizing this principle, people are more likely to be persuaded if what is presented to them is rare or if they feel they will not have a chance at this opportunity again.

Next time you have a critical presentation, sales demonstration or startup pitch — stop and think about how you can be more persuasive with your message.
