I decided to test false consensus along with self-efficacy, self-concept, self-serving bias, hindsight-bias, and attributions. I chose six participants to help me with this study. Three were labeled confederates and did exactly what I told them to do. The other three each had different roles. One was a Pepsi drinker, one a Coke drinker and the last person did not have a preference nor did they drink pop on a regular basis. The first participant, who was a Pepsi drinker came into my experiment under the assumption that the experiment was simply a taste test in which I had gathered four people to taste one type of cola and say whether it was Coke or Pepsi. The confederates all knew it was Coke but I had already told them to say it was Pepsi. Before the tasting all the “participants” discussed whether or not they thought they could distinguish the difference. The Pepsi drinker seemed to be hesitant saying “well I don’t know for sure if I can tell the difference, maybe if I take a drink from each kind.” He even joked said “I definitely could tell the difference if I mixed it with rum.” The others varied, some saying they only drink Coke therefore they would definitely be able to label the cola.
