Exploring Groupthink Bias and Polarisation Bias

Abstract

Cognitive biases play a crucial role in shaping human judgement and choices in the complex environment of decision making. This chapter provides a comprehensive examination of two prominent cognitive biases, groupthink bias, and polarisation bias. In this context, the importance of cognitive biases in decision-making processes is emphasised and placed in a rich research context. By meticulously detailing the methods and sources used in the research, the scope and main objectives of these biases are discussed, and a road map is endeavoured to be presented for a solution. This chapter has two aims: first, to elucidate the role and impact of cognitive biases in decision-making; and second, to provide a comprehensive analysis of two specific cognitive biases - groupthink bias and polarisation bias - and to provide a literature review on the subject, presenting a variety of different views and strategies for overcoming these biases. In addition, real-world examples provide vivid snapshots of how cognitive biases shape these areas.
