System 2


System 2 is our slow, disciplined, effort hungry, largely conscious mind that monitors system 1 and allocates attention to more complex mental problems that require it. However, this system is lazy and will rely on system 1 whenever it thinks it is adequately handling decision making. This concept was introduced by the psychologist Daniel Kahneman in his book Thinking, fast and slow. See also behavioural economics.
