Decision Making: Traditional Method01:14

Decision Making: Traditional Method

4.3K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision Making01:20

Decision Making

277
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Groupthink01:34

Groupthink

46.0K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Robbers Cave

14.4K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Social Loafing01:37

Social Loafing

36.5K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Area of Science:

  • Decision Sciences
  • Operations Research
  • Artificial Intelligence

Background:

  • Reaching consensus in large-group decision-making (MALGDM) is challenging due to attribute and decision-maker conflicts.
  • Existing models often struggle with noncooperative behaviors and diverse opinions in large groups.

Purpose of the Study:

  • To develop a novel consensus model for multiattribute large-group decision-making (MALGDM) that accommodates noncooperative behavior.
  • To improve consensus reaching by grouping similar decision-makers and objectively determining consensus thresholds.

Main Methods:

  • An improved clustering method was employed to group decision-makers based on opinion similarities.
  • A consensus threshold was determined using both objective and subjective criteria to guide the consensus process.
  • The model investigated noncooperative behavior and opinion adjustments within decision-making subgroups.

Main Results:

  • The proposed consensus model demonstrated strong applicability and reliability in handling noncooperative subgroups.
  • The method effectively managed multiattribute interactions within large groups.
  • Feasibility was validated through an emergency decision-making application in flood disaster management.

Conclusions:

  • The novel consensus model provides a robust framework for large-group decision-making, particularly in scenarios with conflicting interests.
  • The approach enhances consensus building by incorporating subgroup dynamics and noncooperative behavior analysis.
  • This method offers a reliable tool for complex decision-making challenges, including emergency response planning.
