“…The first instances of cognitive psychometrics (Batchelder, 1998;Batchelder & Riefer, 1999) involved multinomial processing tree models-often with a focus on consensus analysis-where individual differences in competencies need to be taken into account when deriving unknown correct answers, or "cultural consensus", on a set of knowledge or belief items. Batchelder, Anders, and Oravecz (2018) summarize the mathematical formulations and implementations of Cultural Consensus Theory (CCT) modelsthese have been applied to various problems including extracting shared information from eyewitness reports (Waubert de Puiseau, Aßfalg, Erdfelder, & Bernstein, 2012), perceived personality traits in social networks (Agrawal & Batchelder, 2012), defining psychological concepts (Oravecz, Faust, Levitis, & Batchelder, 2015), and what makes people feel loved (Heshmati et al, 2019).
