The Dangers of Shared Information Bias in Decision-Making

Have you ever been part of a group decision-making process where one individual dominates the conversation and sways the group towards a particular decision? Or have you ever found yourself agreeing with a decision made by the group, even when you had doubts? If so, you may have been the victim of shared information bias.

Shared information bias occurs when individuals in a group tend to focus on information that is already known to the group, while ignoring new or contradictory information. This bias is often the result of social pressures and the desire to conform to group norms, but it can have serious consequences in decision-making.

How it Works

In a group decision-making process, each individual brings their own unique information and perspectives to the table. However, as the group discusses the issue, certain pieces of information may be repeated or emphasized, while other information may be ignored or forgotten.

This is where shared information bias comes into play. If a piece of information is mentioned multiple times, or if it is shared by someone with high status or authority within the group, it tends to be given more weight and consideration. On the other hand, information that is new or contradicts previously discussed information may be discounted or ignored altogether.

Consequences of Shared Information Bias

The consequences of shared information bias can be serious. When individuals in a group decision-making process are more concerned with being seen as agreeable than with making the best decision, the group can fall into a pattern of groupthink. Groupthink is a phenomenon where the desire for harmony and conformity within the group overrides the need for critical thinking and rational decision-making.

When groupthink occurs, group members may overlook important information, fail to consider a range of alternatives, and pursue a decision that is not in the best interest of the group or organization. This can result in missed opportunities, poor decision-making, and even organizational failure.

Avoiding Shared Information Bias

To avoid shared information bias in decision-making, groups should make a conscious effort to seek out and consider new and diverse viewpoints. This can be achieved by assigning a devil’s advocate to the group, who is responsible for pointing out potential flaws in the group’s decision-making process and presenting alternative perspectives.

Another way to avoid shared information bias is to establish clear decision-making criteria before beginning the group discussion. This can help to keep the group focused on the task at hand and ensure that all relevant information is considered.

Conclusion

Shared information bias is a common phenomenon in group decision-making that can have serious consequences. By understanding how it works and taking steps to avoid it, groups can make better, more informed decisions. Remember to seek out new perspectives, establish decision-making criteria, and always be willing to consider new information. With these strategies, you can ensure that your group’s decision-making process is as effective and unbiased as possible.
