Study 1 demonstrated that information about healthy functioning can am
plify health concerns and erode diagnostic confidence. Undergraduate S
s received a hypothetical test showing some level of cells associated
either with pathology or with its absence. The moderate wellness resul
t produced low confidence in one's health estimate and was distressing
to receive. Wellness information may represent an ambiguous nonevent
when testing for disease. Study 2 tested this thesis by adding Ss who
adopted a recovering role to those adopting an illness role. Judgmenta
l uncertainty was greatest-and equivalent-among recovering Ss given th
e moderate illness result and among ailing Ss given a moderate wellnes
s result, and both groups were most willing to consider taking a risky
treatment for the disease.
