摘要:The tendency to think about things in terms of binary opposition is called dichotomous thinking. If dichotomous thinking is strong, it has an extreme response style, that is, to select extreme options in a questionnaire. In order to reduce the influence of dichotomous thinking on the responses to the questionnaire survey, we examined the scale structure (symmetric and asymmetric). A total of 218 undergraduate students responded to the questionnaires; either a symmetric or an asymmetric was used. Results indicated an interaction between the dichotomous belief and the asymmetric questionnaire. In other words, the existence of neutral items affects the tendency of responses by dichotomous thinking.
