Norvig I 614
Rationality/AI research/Norvig/Russell: an agent’s preference behavior does not necessarily mean that the agent is explicitly maximizing that utility function in its own deliberations. (…) rational behavior can be generated in any number of ways. By observing a rational agent’s preferences, however, an observer can construct the utility function that represents what the agent is actually trying to achieve (even if the agent doesn’t know it). >Utility theory/Norvig
, >Preferences/Norvig.
Norvig I 615
[A preference] might be unusual, but we can’t call it irrational.
Norvig I 619
Irrationality/Norvig/Russell: Decision theory is a normative theory: it describes how a rational agent should act. A descriptive theory, on the other hand, describes how actual agents (…) really do act. The application of economic theory would be greatly enhanced if the two coincided, but there appears to be some experimental evidence to the contrary. The evidence suggests that humans are “predictably irrational” (Ariely, 2009)(1).

Literature: popular books on human irrationality: Sway (Brafman and Brafman, 2009)(2), Nudge (Thaler and Sunstein, 2009)(3), Kluge (Marcus, 2009)(4), How We Decide (Lehrer, 2009)(5) and On Being Certain (Burton, 2009)(6). They complement the classic (Kahneman et al., 1982)(7) and the article that started it all (Kahneman and Tversky, 1979)(8).
