The norm of even-handedness is a question-order effect known to occur
in face-to-face interviews when respondents favor one of two complemen
tary or competing opinion questions, both written at the same level of
specificity. After defining and illustrating the concept, evidence of
even-handedness in opinion questions is explored in a Montana mail su
rvey and in recall of recent behavior in Iowa telephone interviews. Th
e Montana survey provides evidence of education effects that are not c
onsistent with previous theories of cognitive sophistication, suggesti
ng that future research must consider the interaction between substant
ive issues and cognitive processes. The Iowa poll provides evidence th
at respondents' recall of their recent behaviors and the behaviors of
their partner also are subject to context effects. This poll also prov
ides evidence that even-handedness operates independently of social de
sirablity, especially among women.
