In "The Idea of Justice," Amartya Sen discusses how people who are heavily doctrinal often exhibit a rigid mindset. Their thinking can be quite simplistic and lacks nuance, as they are primarily focused on defending their beliefs. This crude approach can limit their ability to engage with more complex ideas or perspectives outside their established views.

Sen suggests that such doctrinal thinking can hinder discussions related to justice and moral reasoning. By adhering strictly to their beliefs, these individuals may overlook the importance of critical thinking and discourse, which are essential for a more comprehensive understanding of justice in society.
