‘Alex Ferguson-Style’ Hairdryer Rants Can Motivate Staff, Study Finds

By the Editorial Team · Sunday, August 2, 2026

A study by researchers from Loughborough University and Universidade Católica found that managers who occasionally swear during reprimands can motivate employees with bold and manipulative personality traits more effectively. However, the research highlights that such language often alienates other workers, emphasizing the need for leaders to tailor their communication styles to individual and cultural differences.

A recent study suggests that managers who occasionally use strong language in their reprimands may be more effective in motivating certain employees. The research, conducted by Alexandros Psychogios of Loughborough University and Dritjon Gruda of Universidade Católica in Portugal, examines the role of profane outbursts in leadership, drawing on examples like former Manchester United manager Sir Alex Ferguson, whose famously intense “hairdryer” tirades became part of football folklore.

The researchers surveyed 5,660 employees across 19 countries to assess how swearing by supervisors influences worker satisfaction and perceptions of leadership. Their findings indicate that responses to such language vary considerably depending on individual personality traits as well as cultural context. Specifically, employees who identified with higher levels of psychopathic and Machiavellian traits—characterized by boldness, manipulativeness, and a willingness to take risks—tended to respond more positively to profanity used by their bosses.

Conversely, a significant portion of the workforce reported negative reactions to supervisors’ use of profanities, suggesting that such communication can be alienating or demotivating for many. The researchers caution that while swearing may enhance perceived authority and impact with some employees, it is not a universally effective leadership strategy.

“Our research indicates that effective leadership communication should be adaptable,” Psychogios and Gruda noted. “Leaders should not consider swearing as a one-size-fits-all approach but instead recognize that individual differences and cultural backgrounds shape how these messages are received.”

The study underscores the complex dynamics between managerial communication styles and employee receptivity, emphasizing the importance of tailoring leadership approaches rather than relying on a single method. The findings also provide a nuanced understanding of why reputations of demanding managers like Sir Alex Ferguson endure, as their intense methods may resonate more strongly with particular personality types within their teams.
