How is system 2 is not susceptible to bias?
5 answers
System 2 is traditionally viewed as less susceptible to bias due to its rule-based, rational nature. However, recent arguments challenge this notion by suggesting that System 1, responsible for intuitive reasoning, can also exhibit logical processes akin to System 2, albeit in a different form.
