How did corporate culture, leadership, power and motivation affect Thomas’ level of managerial hubris? 

The strong leaders in the organization gave him freedom to act without fear or hesitation because they saw his ambition as a testament to their own ability to lead. The powerful position he held within the organization provided Thomas with the resources necessary for these risky endeavors, which further reinforced his belief that he was capable of achieving extraordinary results. Lastly, financial rewards coupled with recognition from senior management motivated Thomas to keep pushing himself beyond conventional standards.

All these factors combined played a role in inflating Thomas’ sense of self confidence and ultimately led to him developing managerial hubris – believing that he could do no wrong despite all evidence pointing towards otherwise.
