This is the classic cognitive dissonance experiment........ All I can say is think about it please.
(From the site I mentioned above)
Boring task experiment
In Festinger and Carlsmith's classic 1959 experiment, students were asked to spend an hour on boring and tedious tasks (e.g. turning pegs a quarter turn, over and over again). The tasks were designed to generate a strong, negative attitude. Once the subjects had done this, the experimenters asked some of them to do a simple favour. They were asked to talk to another subject (actually an actor) and persuade them that the tasks were interesting and engaging. Some participants were paid $20 (inflation adjusted to 2009, this equates to $148.40) for this favor, another group was paid $1 (or $7.42 in '2009 dollars'), and a control group was not asked to perform the favour.
When asked to rate the boring tasks at the conclusion of the study (not in the presence of the other "subject"), those in the $1 group rated them more positively than those in the $20 and control groups. This was explained by Festinger and Carlsmith as evidence for cognitive dissonance. The researchers theorized that people experienced dissonance between the conflicting cognitions, "I told someone that the task was interesting", and "I actually found it boring." When paid only $1, students were forced to internalize the attitude they were induced to express, because they had no other justification. Those in the $20 condition, however, had an obvious external justification for their behaviour, and thus experienced less dissonance.
