Abstract | The validity of true experiments is threatened by a class of self-report biases that affect all respondents at pretest, but which are diminished by treatment. Four of these inaccurate self-evaluation biases are discussed. Means of detection include external criteria, special conditions of measurement, and retrospective pretests. (TJH) |
