Abstract
Decades of research on human judgment and decision making
have demonstrated the presence of cognitive biases. This literature
has led to a negative view of our judgmental capacities, a view
that Krueger (1998) laments. However, the road to a more positive
perspective first requires a clearer picture of the extent of
bias and of methods for combating it. Rather than continue to
debate the existence of biases, we should strive to understand
their prevalence and magnitude, catalog them by source, and address
them through corrective procedures. Some of Krueger's suggestions
appear highly relevant for these goals.
