In the experiment, participants from one group of smokers were asked to think about reasons to quit smoking and write them down on a piece of paper. Participants from a second group of smokers were asked to read pre-written anti-smoking arguments.
Both groups of participants were then asked to wait up to 30 minutes while the experimenter prepared a task unrelated to the actual experiment. Individuals who generated their own arguments against smoking abstained from smoking cigarettes longer than those who read pre-written anti-smoking arguments.
The results of this experiment suggest that self-generated information has a greater influence on smoking behavior (at least in the short-term) than information that is simply read.
Many anti-smoking campaigns try to “educate” people out of smoking cigarettes. They provide a great deal of information on the potential health hazards of smoking and try to convince smokers to quit. This approach can be dangerous as smokers might feel as though they are being attacked and react defensively. The truth is, many smokers already understand the consequences of tobacco use. If anti-smoking campaigns could find a way to develop personal beliefs against smoking, smokers might have an easier time not lighting up.
