When attitudes are surveyed, the subject’s answer does not reflect only his actual status, but also his perception of it and the very awareness of having one. The most common techniques are those implying the use of sentences expressed as an assertion, that the subject must approve or disapprove. A large amount of scientific literature has shown that it often stimulates mechanical and/or acquiescent answers. Several research findings (1999-2009) are presented in this paper. In these studies we compare the Forced Choices (FC) in different kinds of interviews with the Likert and Cantril scales. According to empirical evidence, it seems that the design complexity of FC is largely paid off by its ability to provide more reliable answers.
