Monetarily incentivized dishonesty, such as scams, tax evasion, and corruption, is a problem of an utmost importance for both individuals and societies. In this regard, a large and constantly growing body of research in Psychology and Behavioral Economics focuses on both situational and individual factors that are related to dishonesty. In my presentation, I will discuss two topics embedded within this line of research. Specifically, I will focus on the relation between the basic personality trait of Honesty-Humility (from the HEXACO Model of Personality) and dishonesty in contexts where two ethical motivations are at odds, namely, (1) collaborative dishonesty (where collaboration and honesty are at odds; N = 499), and (2) trustworthy dishonesty (where trustworthiness and honesty are at odds; N = 7,115). Furthermore, I will discuss the relation between creativity and (un)ethical behavior in contexts involving dishonesty with a focus on (1) creativity and dishonesty (N = 1,125), as well as (2) creativity and generation of (un)ethical justifications (N = 907). In brief, the findings suggest that Honesty-Humility is a consistent predictor of (un)ethical behavior in contexts involving dishonesty, whereas the role of creativity in predicting the behavior in question is rather inconclusive.
