In a classic study, a researcher randomly selected and assigned people to a study on assertiveness. Group one was asked to write about six times they had been assertive (which all of group one could do). Group two was asked to write about twelve times they had been assertive (most struggled to come up with this many). Then, everyone was asked to rate their own level of assertiveness at that moment. The subjects in group one scored themselves much higher than group two.

 

Use a cognitive concept discussed in class to explain why this likely occurred.
