“…The first of the limitations is cross-sectional data collection. Notably, testing the indoctrination hypothesis cross-sectionally makes it difficult to establish causality (Bauman and Rose, 2011; Collin and Schmidt, 2020; Hellmich, 2019; Hummel et al, 2018; Neubaum et al, 2009; Petersen and Ford, 2019; Seçilmis, 2014). A second limitation is the lack of replication of the leading studies in other universities (Collin and Schmidt, 2020; Hellmich, 2019; Neubaum et al, 2009; Petersen and Ford, 2019; Segal et al, 2011), in other countries (Delgado et al, 2019), or with students who have a higher level of economics education (MBA or EMBA) (Neubaum et al, 2009).…”
