It also invokes another popular science classic: {{author|Julian Jaynes}}' idea of the “[[bicameral mind]]” <ref>{{br|The Origins of Consciousness in the Breakdown of the Bicameral Mind}}</ref> wherein there are large aspects of our daily existence, which we consider them conscious, really are not: driving by rote to the office, playing a musical instrument — these are also mental processes, I imagine Kahneman would say, undertaken by System 1. Jaynes was widely viewed as a bit eccentric: Kahneman's work suggests he may have been right on the money. | It also invokes another popular science classic: {{author|Julian Jaynes}}' idea of the “[[bicameral mind]]” <ref>{{br|The Origins of Consciousness in the Breakdown of the Bicameral Mind}}</ref> wherein there are large aspects of our daily existence, which we consider them conscious, really are not: driving by rote to the office, playing a musical instrument — these are also mental processes, I imagine Kahneman would say, undertaken by System 1.

It gets interesting for Kahneman where the division of labour between the systems | It gets interesting for Kahneman where the division of labour between the systems isn’t clear cut. System 1 can and does make quick evaluations even where system 2's systematic analysis would provide a better result (these are broadly the "bad" snap judgments of ''Blink''). But System 2 requires dedicated mental resource (in Kahneman ugly expression, it is "effortful"), and our lazy tendency is to substitute (or, at any rate, stick with) those "cheaper" preliminary judgments where it is not obviously erroneous to do so (and by and large, it won’t be, as System 1 will have done its work). Kahneman's shorthand for this effect is WYSIATI: What You See Is All There Is. | ||
Kahneman invites the reader to try plenty of experiments aimed at illustrating his fecklessness, and these hit their mark: it is distressing to repeatedly discover you have made a howling error of judgment, especially when you knew you were being tested for it. This has massive implications for those who claim group psychology can be predicted on narrow logical grounds. The latter half of {{br|Thinking Fast and Slow}} focusses more on our constitutional inability to rationally adapt to probabilities and soundly wallops the notion of [[homo economicus]], the rational chooser each of us imagine ourselves to be. This is where Kahneman's Nobel Prize-winning Prospect Theory and gets full run of the paddock. | Kahneman invites the reader to try plenty of experiments aimed at illustrating his fecklessness, and these hit their mark: it is distressing to repeatedly discover you have made a howling error of judgment, especially when you knew you were being tested for it.
