Thinking, Fast and Slow

information. As Gigerenzer has emphasized, his heuristics are different
from those that Amos and I studied, and he has stressed their accuracy
rather than the biases to which they inevitably lead. Much of the research
that supports fast and frugal heuristic uses statistical simulations to show
that they could work in some real-life situations, but the evidence for the
psychological reality of these heuristics remains thin and contested. The
most memorable discovery associated with this approach is the
recognition heuristic, illustrated by an example that has become well-
known: a subject who is asked which of two cities is larger and recognizes
one of them should guess that the one she recognizes is larger. The
recognition heuristic works fairly well if the subject knows that the city she
recognizes is large; if she knows it to be small, however, she will quite
reasonably guess that the unknown city is larger. Contrary to the theory, the
subjects use more than the recognition cue: Daniel M. Oppenheimer, “Not
So Fast! (and Not So Frugal!): Rethinking the Recognition Heuristic,”
Cognition 90 (2003): B1–B9. A weakness of the theory is that, from what
we know of the mind, there is no need for heuristics to be frugal. The brain
processes vast amounts of information in parallel, and the mind can be fast
and accurate without ignoring information. Furthermore, it has been known
since the early days of research on chess masters that skill need not
consist of learning to use less information. On the contrary, skill is more
often an ability to deal with large amounts of information quickly and
efficiently.

evaluate their happiness : A telephone survey conducted in Germany
included a question about general happiness. When the self-reports of
happiness were correlated with the local weather at the time of the
interview, a pronounced correlation was found. Mood is known to vary with
the weather, and substitution explains the effect on reported happiness.
However, another version of the telephone survey yielded a somewhat
different result. These respondents were asked about the current weather
before they were asked the happiness quest {ppiournal ofion. For them,
