Any of these antecedents could have been connected with different consequences—in particular with many scenarios involving safe landings. What we hav… - Robyn Dawes

Unfortunately, there are many irrational conclusions and beliefs in our culture from which to choose. Those analyzed at some length—and as precisely as possible—are those with which I am most familiar. With public opinion polls indicating that more people in the United States believe in extrasensory perception than in evolution, it is not surprising that examples abound.

Thus, even if we accept that the people are deviously neurotic rather than outright irrational, we still must specify exactly how they believe that the rest of us can be fooled by them. Throughout the book, I will assert that they are urging us (and themselves) to “associate, but not compare.” This book is written in partial hope that the readers will end up making appropriate comparisons, rather than simple associations—which generally lead to a deficient specification of the categories necessary to reach a rational conclusion.

Two biases of memory, however, tend to enhance the illusory nature of our retrospective “understanding” of our own and others’ lives. The first is that we tend to overestimate specific events relative to general categories of events. The second is that we tend to recall specific events and to interpret them in ways that make sense out of a current situation—“sense” in terms of our cultural and individual beliefs about stability and change in the life course. Thus, memories, which appear to be beyond our control as if we are observing our previous life on a video screen, are like anecdotes in that they are often (inadvertently) “chosen for a purpose.” The result is that they will tend to reinforce whatever prior beliefs we have, just as anecdotes tend to reinforce the points they are meant to illustrate.
