... Triggered by the rise of research on managerial cognition (Sarkar, Osiyevskyy, & Clegg, 2018;Stubbart, 1989;Wilms, Winnen, & Lanwehr, 2019), a large number of scientific publications have provided ample empirical evidence that the emergence of hubrisa cognitive bias expressed through high levels of self-confidence, exaggerated pride, and overinflated positive self-evaluations (Judge, Piccolo, & Kosalka, 2009;Owen & Davidson, 2009;Petit & Bollaert, 2012) is by no means a rare phenomenon in leadership contexts.

The leadership behaviors of affected executives are found to deviate from normative standards (Fox & Groesser, 2016;Hiller & Hambrick, 2005;McManus, 2016), which is mainly attributed to a grandiose sense of themselves that hubristic leaders possess (Hayward & Hambrick, 1997;Judge et al., 2009;Petit & Bollaert, 2012). ...
