Some cancer screening programs are built on contentious evidence, but the public are generally positive about screening. Many professional organizations have settled on a fudge: allow the people to decide for themselves. Given the potential limitations of individual decision-making, there is increasing support for helping individuals to make better decisions. This paper presents experimental data supporting the claim that individuals are largely unresponsive to data about screening and base their decisions upon factors that professionals would consider inappropriate reasons for screening. The most plausible explanation for this phenomenon comes from accessibility bias. Professionals can no longer sustain the argument that, with respect to cancer screening, individual choice reflects a meaningful expression of autonomy.
