In addition to considering the implications of task and stimuli characteristics for decision processes and outcomes, decision researchers have studied the role of social and cultural factors and individual differences in decision making. Individual decision making has been investigated over decades in several disciplines, for instance, economics and social psychology. Group testing as the name implies it is about examining an individual by a whole group. Sometimes groups have very clear and explicit rules that keep people in line; in other cases, the rules or pressures are more subtle. For example, groups may suffer from coordination problems. Group decision-making commonly known as collaborative decision-making is a situation faced when individuals collectively make a choice from the alternatives before them.

Decisions are taken by a group of persons. Group decision making has certain advantages over individual decision making, particularly when the decisions are complex; require the acquisition and processing of a variety or large amounts of information; and require acceptance and successful implementation of decisions by others. Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. How groups form, conform, then warp our decision-making, productivity and creativity. While groups have the potential to arrive at an effective decision, they often suffer from process losses. Research has shown much variation in the impacts of factors such as these on individual and group performance (Guzzo & Dickson, 1996). Much of the early work on group decision-making focused on individual ... 1986). An individual tends to experience decision fatigue when faced with a lot of decisions—for example, a study of judges showed that they made better decisions earlier in the day, and the quality of their decisions diminished as the day went on. Finally, when the decision is made by a group rather than a single individual, implementation of the decision will be easier because group members will be invested in the decision.

Group decisions are costly in terms of time and money. According to behavioralist Isabel Briggs Myers (1962), a person's decision making process depends to a significant degree on their cognitive style. This article examines the influence of individual vs group learning on a decision-making process in ABMs enhanced with ML. 3.
