Pictures can also be deceiving and illogical but still powerful, considering the impact that they might impose on the people. For example, a few years back, there was this advertisement on a new KFC meal, the Banditto Pocket. The TV advertisement showed how a Mexican prisoner actually bent the bars in the prison and escaped. Another current example will be the advertisement of a flying man after eating a Ricola sweet. These advertisements are though illogical but still possess the power of influencing the consumers in buying the products.

When conveying important information about the benefits of a medication to patients, pictures appear to be more powerful than words.

A study of 100 patients with cardiovascular disease finds that 57 percent prefer information about the risks and benefits of treatment be presented graphically. Other ways of expressing risk and benefit were less popular among study participants. Only 19 percent preferred information expressed as relative risk, 13 percent preferred absolute risk, 9 percent preferred natural frequencies, and only one patient preferred the information be presented in terms of an odds ratio.

Notably, no patients preferred number needed to treat, a method for communicating risk and benefit that is very useful to clinicians. The authors assert that these findings support the need for the development of visual aids to support shared clinical decision making.
