Kip Viscusi rejects my critique of his work and restates his view that indi
viduals greatly overestimate the risks from lung cancer and other diseases
caused by smoking. But Viscusi's methods are deeply flawed and his analyses
, arguments, and conclusions are incorrect. First, he neglects to take into
account optimism bias, which leads smokers to believe that they personally
are at less risk than other smokers. Second, he fails to demonstrate that
smokers appreciate the cumulative nature of smoking risks and the power of
addiction that makes it extraordinarily difficult for them to stop smoking
when their preferences change and they desire to quit, Third, the quantitat
ive judgments of risk that Viscusi relies upon are so highly determined by
methodological biases as to be completely unreliable. A substantial body of
evidence supports the conclusion, contrary to Viscusi's, that many young p
eople do not adequately appreciate the risks of smoking. Copyright (C) 2000
