Sibongile is the group leader in a group project with four of her classmates. She consistently undervalues the ideas and contributions from her group members and instead relies solely on her own decisions as group leader. Which type of bias is Sibongile demonstrating?

Sibongile is demonstrating confirmation bias by consistently undervaluing the ideas and contributions from her group members and relying solely on her own decisions as the group leader. Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses while ignoring and undervaluing opposing or alternative viewpoints.

Sibongile is demonstrating a bias known as "authority bias" or "status quo bias."

The type of bias that Sibongile is demonstrating is known as "confirmation bias." Confirmation bias occurs when someone favors information that confirms their existing beliefs or assumptions while ignoring or undervaluing information that contradicts those beliefs.

In this case, Sibongile consistently undervalues the ideas and contributions from her group members, preferring her own decisions as the group leader. This suggests that she may have formed a belief that her own ideas are inherently better or more valuable compared to those of her group members. Sibongile's behavior reflects a tendency to confirm her pre-existing belief in her decision-making capabilities as the group leader.

To arrive at this answer, I analyzed the information provided in the question and applied knowledge of cognitive biases. Confirmation bias is a common bias that can affect decision-making and group dynamics.
