“…The application of AI in personality research is burgeoning, albeit emergent, with improvements in natural language processing together with the growth of digital communications providing an abundance of consumer behavioural data (Davenport et al , 2020; Diehl et al , 2003; Kietzmann et al , 2018; Flavián et al , 2019; van Noort et al , 2020; Helberger et al , 2020).
