The article titled 'Understanding Cognitive Bias in Decision-Making' explores the various cognitive biases that influence the decisions we make. It begins by outlining the concept of cognitive bias, stating that these biases are systematic patterns of deviation from norm or rationality in judgment. The author introduces examples of common biases, such as confirmation bias and anchoring bias, and explains their impact on both personal and professional decision-making processes. Following this introduction, the article provides statistical data illustrating how these biases can lead to suboptimal decisions in corporate settings.
