While there are methods and measures to examine several forms of response distortion (e.g., careless responding, or social desirability), it must be noted that all these measure constitute attempts, which are performed after the questionnaire has been completed, to detect or eliminate the impact of non-observable factors (like carelessness or social desirability; Connelly & Chang, 2015;de Vries et al, 2014;Dodou & de Winter, 2014;Huang et al, 2012Huang et al, , 2015Paulhus, 2002;Paunonen & LeBel, 2012). However, carrying out post hoc analyses can only provide an estimation of whether a response was careless, or socially desirable, while the real status of the response (careless or not, biased or from a conscientious individual) remains unknown.…”
