2.2.2 Focus on individuals similar to the target market
The Bystander Effect - Complies
3.5.1 How to use fear to persuade: Emphasize bad outcomes, assign blame, and call for actions by others.
Research on mass communications during WWII concluded that mild fear was more persuasive than strong fear. Later research challenged this finding. A meta-analysis of 98 experimental and non-experimental studies confirmed that strong fear is more effective (Witte & Allen 2000).
3.6.1 Example of Provocation: Increase diversity bake sale: 2011
Persuasion Principle 3.6.1 says, “Provoke customers only when it attracts attention to a selling point.” Here, I present only an example of an application, not evidence. In September 2011, a bake sale held at the University of California at Berkeley offered cupcakes at various prices depending on the customer’s race and gender. More
7.2.1 Use simple prose for high-involvement products with strong arguments -- and obfuscate for products with weak arguments, but only if the message is delivered by a high-status source.
In a survey of 110 Stanford undergraduates, 86% admitted they made their writing more complex so as to appear to be more intelligent. Two-thirds admitted to using a thesaurus to increase complexity. Is obfuscation a useful persuasive strategy for students? More
7.13.1 Use disclaimers or corrective advertising only if they provide information customers need.
A review of the 18 studies with 25 experiments reinforces the conclusion that market forces (i.e., cautious customers, and firms’ desires to please customers and avoid law suits) are best for consumers in practice. Government mandated disclaimers were expensive and confusing in all experimental comparisons, and in all of the 15 studies (with 22 experimental comparisons) that examined intentions or decisions (Green & Armstrong 2012).
7.13.1 Do mandatory disclosures help consumers?
A review of the evidence on mandated disclosures covered not only advertising but also areas such as Miranda rights, informed consent, and Institutional Review Boards. Such disclosures may not seem contentious as they simply involve providing more information to those who might find it useful. Surprisingly, then, Ben-Shahar and Schneider (2011) were unable to find a single mandatory disclosure for which the benefits outweighed the costs. More

Conditions: High vs. low involvement
Marshmallow study for impatience. The marshmallow study has been described as relating to self-control, delayed gratification, or patience. Originally done by Walter Mischel in 1972, it shows that some people are willing to pause and think about an action before plunging ahead. Note that the concept of involvement is related to the type of customer as well as to the product. This and related tests, which have been given to people as young as 4 years, is predictive of how people fare in later life. For example, related tests been shown to be better than IQ as a predictor of how someone will do in school (see Duckworth & Seligman, 2005, “Self-discipline outdoes IQ in predicting academic performance of adolescents,” Psychological Science, 16, 939-944. There are many demonstrations on YouTube besides the one shown here. For a description, see Deferred Gratification.
Here is an overview of the influence principles by the man who identified them, Robert Cialdini.
2.2.1 Show that the product is widely used (social proof)
Asch experiment: In 1955, Solomon Asch asked subjects to participate in a "vision test." In reality, all but one of the participants in this experiment were confederates of the experimenter. The study was really about how the lone subject would react to the confederates' behavior. It demonstrated that a group’s opinions are very powerful in inducing conformity, even though the subjects had no prior acquaintance with the other subjects. There were many extensions of this study, which is regarded as one of the classic studies on social psychology. For an interesting description of this stream of research see Asch’s Conformity Study.
Elevator behavior: This demonstration, from Candid Camera, shows how people conform to the behavior of others.
JohnStossel demostrates experiments on the effects of attribution on behavior. He also describes the famous blue-eye brown-eye demonstration. The effects are strong as you will see.
Milgram’s obedience study: It has always been known that authority affects behavior. However, the strength of this effect was not fully appreciated until the influential studies by Stanley Milgram starting in the 1960s. For an excellent summary of this and related follow-ups, see the Psychwiki entry.
4.0 Mere exposure
This demonstration shows that exposure to messages affects us even when we pay little attention (low involvement). In contrast to the viewpoint of the makers of the video, this is not based on subliminal images.
The famous Dr. Fox study showed that complex but nonsensical lectures to faculty and staff received high ratings. Attendees commented that while they did not understand everything Dr. Fox said, he certainly "knew his stuff." More
7.2.1 Use simple prose for high-involvement products with arguments
Over 100 published science journal articles just gibberish. More
