As mentioned, the purpose of group think is to reach a consensus among the members without conflict. Therefore, the members don’t critic and evaluate others ideas so that arguments do not arise. Although this could lead to groups making decisions that are not necessarily the most thought out by all the individuals, it may present new ideas and information to a member who was completely unaware of it previously. Group think also leads to a spiral of silence where an individual might not give their suggestions or opinions because they feel they are in the minority.
This idea of groupthink applies to the games Digg and Urn. The rules for Urn are “There are two indistinguishable urns. Urn ‘W’ has two white balls, one yellow. Urn ‘Y’ has two yellow balls, one white. A proctor will flip a coin to choose an urn. You must guess which urn it is after seeing one ball from the urn AND AFTER HEARING ALL THE GUESSES OF THOSE BEFORE YOU. Your goal is to choose wisely.” People make decisions based off of the others responses and even may choose to ignore their own information. They may forgo the decision that they would have made if they had not heard the other responses. In this game the majority of people conform to what others do and say. Digg is basically an online version of Urn, where “measuring a story’s importance is based on a semi-random set of people voting for or against a semi-random set of news stories.” Information is given to the voters by following a web of links of blogs. After people see the other blogs they tend to follow what they have to say because they think the previous voters are rational in their decisions.

Transactive memory is based on expertise and how people tend to focus on areas they have more knowledge about and rely on other people in areas that they have more knowledge about. Andrea Hollingshead notes that “rather than trying to learn and remember all information relevant to their daily tasks themselves, members simply ask the designated expert on a need-to-know basis. Transactive memory develops naturally as a way to reduce individual cognitive effort and to provide group members with a larger pool of information.” Members must be familiar with the other’s strengths so that they can allocate certain areas to each member appropriately. In interactive games, this can be beneficial when a group member lacks the ability to do a certain task that another member is much better at. For example, any interactive online game that allows separate tasks to be done by different people each person will work on the area that they are most knowledgeable about without ever having to work on other areas. This way the group can win the game or strengthen the abilities of the characters more efficiently.
