P.20- intuition from experience is good but not all people make intuitive judgements from experience (they are inexperienced ) – Enter system 1.
System 1: fast, immediate (I like this) involuntary, effortless
System 1 can think metaphorically, causally, associatively but not statistically (a mode that requires multiple forms of thinking at once) – not accessible to system 1.
Examples: complete phrase “bread and …” Detect hostility in voice. Drive car on empty road. Recognise “meek and tidy soul with a passion for detail” resembles an occupational stereotype.
System 2: slow, deliberate (should I like this?), voluntary, effortful. Operations of system 2 are associated with subjective experience of agency, choice, and concentration.
Examples.fill out a tax form, tell someone your phone number, check the validity of a complex logical argument.
P.21 – system 1 can generate very complex ideas but only system 2 can order them
P.28 – we have many cognitive illusions. The question is whether they can be overcome. Probably not. System 2 would need to put in too much effort to make sure no system 1 errors are made – a tedious, impractical way to live life, but a compromise is possible. Recognise situations where system 1 errors are likely and the stakes are high.
System 1 is a nickname for automatic system
System 2 is a nickname for effortful system.
“This is your system 1 talking. Slow down no let your system 2 take control”
Chapter 2: Attention and Effort
