Methods of persuasion, the Six Key Principles

The document outlines six key principles of persuasion identified by Robert Cialdini, which are based on scientific research into human behavior. These principles—reciprocation, social proof, commitment and consistency, liking, authority, and scarcity—demonstrate how influence can be effectively applied in marketing and decision-making. Each principle is supported by experiments that illustrate their powerful impact on compliance and behavior.

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.”

Methods of persuasion, the Six Key Principles
- 1. METHODS OF PERSUASION Prakhar Gupta
- 2. Influencing others isn’t magic or luck- it is science. Robert Cialdini, Regents’,Professor of Psychology and Marketing, Arizona State University, has spent 30 years studying the ways people are influenced. He’s whittled his findings down to six key principles, found in the fifth edition of ‘Influence: Science and Practice’. Science behind the Principles “People’s ability to understand the factors that affect their behaviour is surprisingly poor,” Cialdini says. Most people can’t explain why they made a particular decision. But Cialdini can. And being able to identify the underlying factors that influence decisions means he also understands how to use them to get more positive responses.
- 3. 1: Reciprocation • EXPERIMENT CONDUCTED: Social scientist Randy Garner published a 2005 experiment that tested whether sticky notes could persuade people to respond to a marketing survey. He sent one-third of the surveys with a hand-written sticky note requesting completion, one-third with a blank sticky note, and one-third without a sticky note. Results: 1. Hand written sticky notes - 69% compliance 2. Blank sticky note - 43% compliance 3. No sticky note - 34% compliance
- 4. “The principle of reciprocation was born out in the fact that not only did those who received the hand-written note have twice as much compliance, the quality of the answers they gave was significantly better,” Cialdini says. • APPLICATION The reciprocation principle explains why free samples can be so effective. People who receive a free, unexpected gift are more likely to listen to a product’s features, donate to a cause, or tip a waitress more money. The gifts do not have to be expensive or even material; information and favors can work.
- 5. 2: Social Proof • EXPERIMENT CONDUCTED Cialdini and a team of colleagues ran a soon-to-be published experiment to see which types of signs would most encourage Arizona hotel visitors to reuse towels. They tested four types of signs: 1. Cited environmental reasons to encourage visitors to reuse their towels. 2. Said the hotel would donate a portion of end-of-year laundry savings to an environmental cause. 3. Said the hotel had already given a donation and asked: “Will you please join us?” 4. Said the majority of guests reused their towels at least once during their stay.
- 6. Percentage of those who reused towels per request: - Sign 1: 38% - Sign 2: 36% - Sign 3: 46% - Sign 4: 48% 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. “What’s most interesting to me,” Cialdini says, “is that the most effective strategy was entirely costless to the hotel. But I’ve never seen it used by any hotel room in any city.”
- 7. • APPLICATION Testimonials from satisfied customers show your target audience that people who are similar to them have enjoyed your product or service. They’ll be more likely to become customers themselves. A similar principle applies to television commercials that say: “If our lines are busy, please call again.” Instead of saying “Operators are standing by.” The first response implies that other people like your offer so much that the phone lines are busy, which may persuade others to act similarly.
- 8. 3: Commitment and Consistency • EXPERIMENT CONDUCTED In 1987, social scientist Anthony Greenwald approached potential voters on election- day eve to ask whether they would vote and to provide reasons why or why not. 100% said they would vote. On election day, 86.7% of those asked went to the polls compared to 61.5% of those who were not asked. Those who publicly committed to voting on the previous day proved more likely to actually vote
- 9. • APPLICATION People want to be both consistent and true to their word. Getting customers or co- workers to publicly commit to something makes them more likely to follow through with an action or a purchase. Getting people to answer ‘yes’ makes them more powerfully committed to an action, Cialdini says. For instance, don’t tell people: “Please call if you have to cancel.” Asking “Will you please call if you have to cancel?” gets customers to say yes, and measurably increases their response rates.
- 10. 4: Liking • EXPERIMENT 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%).”
- 11. • APPLICATION “One of the things that marketers can do is honestly report on the extent to which the product or service – or the people who are providing the product or service – are similar to the audience and know the audience’s challenges, preferences and so on,” Cialdini says. So , for instance, sales people could improve their chances of making a sale by becoming more knowledgeable about their prospects’ existing preferences.
- 12. 5: Authority • EXPERIMENT CONDUCTED Stanley Milgram, Psychologist, Yale University, conducted a 1974 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.
- 13. “According to 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.” • APPLICATION When people are uncertain, they look outside themselves for information to guide their decisions. Given the incredible influence of authority figures, it would be wise to incorporate testimonials from legitimate, recognized authorities to help persuade prospects to respond or make purchases.
- 14. 6: Scarcity • EXPERIMENT CONDUCTED 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.’”
- 15. “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.” • APPLICATION Say the authors: “The tendency to be more sensitive to possible losses than to possible gains is one of the best-supported findings in social science.” Therefore, it may be worthwhile to switch your advertising campaign’s message from your product’s benefits to emphasizing the potential for a wasted opportunity: - “Don’t miss this chance…” - “Here’s what you’ll miss out on…” In any case, if your product or service is genuinely unique, be sure to emphasize its unique qualities to increase the perception of its scarcity.
