Study Shows Entrepreneurs Have Higher Testosterone Levels and Risk-Taking Behaviors Than Non-Entrepreneurs

Study Shows Entrepreneurs Have Higher Testosterone Levels and Risk-Taking Behaviors Than Non-Entrepreneurs

In this study published in 2006, researchers aimed to investigate the relationship between testosterone levels, risk-taking propensity, and entrepreneurial behavior. The study found that individuals with higher salivary testosterone levels are more likely to behave entrepreneurially, and that testosterone is positively related to risk propensity. The study also found that risk-taking propensity partially mediates the relationship between testosterone and entrepreneurship.

Testosterone is associated with risk-taking, assertiveness, fearlessness, and persistence, which has also been linked to entrepreneurship. This association is shown through various studies conducted on humans and animals, indicating a connection between testosterone and dominance-seeking and status-seeking behaviors.

However, the link between testosterone and entrepreneurship is not direct, as entrepreneurship is a socially constructed term with no objective testing procedures. Nevertheless, there is considerable overlap between the entrepreneurship and testosterone literatures, particularly with regard to risk-taking. It is generally believed that entrepreneurs have a greater propensity for risk than non-entrepreneurs. Although this view is controversial, various researchers have found empirical support for the relationship between risk propensity and entrepreneurship.

The study looked at the relationship between testosterone levels and entrepreneurial behavior, specifically full-time involvement in creating a new venture. Data were collected from 31 MBA students with significant prior involvement in new venture creation and from 79 other student subjects with no new venture start-up experience. The 31 male participants categorized as entrepreneurs had led a new venture, with average annual revenues of $600,000 (Canadian dollars) and an average firm size of seven employees. 

The study was limited to only male participants due to sample size constraints, with 166 out of 205 male students initially chose to fully participate in the study. The number of female participants was small, and only four of them identified themselves as having prior entrepreneurial experience. Additionally, females taking oral contraceptives were asked to exclude themselves from the study as it artificially suppresses testosterone levels. The researchers noted that assaying female saliva would also have incurred added expense and the fact that testosterone affects males and females differently. As basal testosterone levels are substantially different for males and females, pooling male and female data was inadvisable, therefore all females were excluded from the study.

The relationship between testosterone levels and occupation has been a subject of interest for researchers, but until now, no studies have compared the testosterone levels of entrepreneurs and non-entrepreneurs. One large study, which examined 4462 male military veterans, found a strong association between general occupational class and individual differences in testosterone level. Blue-collar workers were found to have higher testosterone levels than white-collar professionals, and farmers had the lowest testosterone levels among all major occupational groups. More specific studies have shown interesting results, such as male trial lawyers having higher average testosterone levels than male non-trial lawyers, and male construction workers having higher average testosterone levels than lawyers. Women in different professions were also studied, and female lawyers were found to have higher testosterone levels than female nurses. Male actors and professional athletes have higher testosterone levels than ministers and farmers. Overall, the study provides a promising first step towards understanding how biological differences may affect business behavior.

In conclusion, the results of the study indicate that there is a positive relationship between salivary testosterone levels and entrepreneurial behavior. More specifically, this relationship is mediated by risk propensity. While the study focused on a biological attribute, it is important to note that entrepreneurial behavior is influenced by a wide range of social and environmental factors as well. The findings suggest that biological differences, such as testosterone levels, can play a role in understanding entrepreneurial behavior. While not a single determining factor, an individual's testosterone level can contribute to their likelihood of engaging in entrepreneurial activities. These findings highlight the importance of considering biological factors when studying entrepreneurship, and suggest that heuristics and biases used by entrepreneurs may have a biological basis.
