The dual process model is a conceptualframework that forms the process of thinking and decision making. It highlights the idea that we use two different systems of thinking: S1 (intuitive) and S2 (rational)
Both systems (System 1 and System 2) worktogether. We are usually on System 1 but System 2 can override if necessary
System 1 (fast INTUITIVE)
Happens on an automatic level, requiring little effort and time
Efficient, saves time and energy since it is based on our instinctive responses and pastexperiences
Useful in situations where split-second responses are required
System 1/intuitive thinking is prone to bias and heuristics which can result in errors or inaccuracies
When might system one be used?
Stepping over a puddle
Knowing what 2+2 is
System 2 (slow RATIONAL)
Doesn't happen automatically, rather it is a deeper, more analytical form of information processing
Increases reliability and accuracy of decisions and problem-solving
Not the most efficient way of thinking since it requires cognitiveenergy and time
