“…One of the major threats to validity in survey research comes from participants who are inattentive, respond randomly to survey questions (Kim et al, 2018; King, Kim, and McCabe, 2018; see Chandler, Paolacci and Hauser, 2020 for review), or are ‘mischievous’, providing responses that are intentionally false or misleading (Fan et al, 2006; Robinson-Cimpian, 2014; Kramer, Rubin and Coster, 2014; Fish and Russell, 2018; Kaltiala-Heino and Lindberg, 2019; Li, Follingstad. Campe, and Chahal, 2020; see Cimpian et al, 2020 for a review).
