how does duplex mind relates to stereotype and prejudice

Duplex mind, also known as dual process or dual system theory, is the idea that the human mind consists of two separate systems for processing information: System 1, which operates automatically and intuitively, and System 2, which is slower and more deliberate.

Stereotypes and prejudice often stem from the automatic processing of information by System 1. When we encounter someone who fits a particular stereotype, our brains automatically categorize them based on that stereotype without consciously considering the individual's unique characteristics. This can lead to biased attitudes and behaviors towards that person.

Prejudice can also be perpetuated by the cognitive shortcuts and heuristics that System 1 relies on, such as confirmation bias or availability heuristic. These biases can reinforce and perpetuate stereotypes and prejudice, as individuals may only pay attention to information that supports their preconceived notions and disregard conflicting information.

In order to combat stereotypes and prejudice, it is important to engage System 2, which involves more deliberate and critical thinking. By consciously challenging and questioning our automatic reactions and biases, we can work towards overcoming stereotypes and prejudice and viewing others as individuals rather than members of a specific group.
