Spoken utterances (secondary data) for the last full year of being a CEO from at least two different sources (retrieved online from publicly accessible websites) have been used for the analysis. The last full year of being a CEO has been chosen as being the most ‘hubristic’ year as according to the research on Hubris Syndrome, it tends to develop over time with the acquisition of significant power and abates once power is lost (Owen & Davidson, 2009; Owen, 2016).
