About every two weeks we will have our Leadership Lab meetings. Guests are welcome, both to present ideas and to simply attend and listen. If you want to learn more or would like to attend, please contact Wendy de Waal-Andrews (firstname.lastname@example.org).
Here are our most recent and upcoming meetings:

Title: Hormones in speed-dating: The role of testosterone and cortisol in attraction
There is evidence that testosterone and cortisol levels are related to the attraction of a romantic partner; testosterone levels relate to a wide range of sexual behaviors and cortisol is a crucial component in the response to stress. To investigate this, we conducted a speed-dating study among heterosexual singles. We measured salivary testosterone and cortisol changes in men and women (n = 79) when they participated in a romantic condition (meeting opposite-sex others, i.e., potential romantic partners), as well as a control condition (meeting same-sex others, i.e., potential friends). Over the course of the romantic speed-dating event, results showed that women’s but not men’s testosterone levels increased and cortisol levels decreased for both men and women. These findings further indicate that men’s testosterone and cortisol levels were at ceiling level in anticipation of the event, whereas for women, this appears to only be the case for cortisol. Concerning the relationship between attraction and hormonal change, four important findings can be distinguished. First, men were more popular when they arrived at the romantic speed-dating event with elevated cortisol levels. Second, in both men and women, a larger change in cortisol levels during romantic speed-dating was related to less selectivity. Third, testosterone alone was unrelated to any romantic speed-dating outcome (selectivity or popularity). However, fourth, women who arrived at the romantic speed-dating event with higher testosterone levels were more selective when their anticipatory cortisol response was low. Overall, our findings suggest that changes in the hormone cortisol may be stronger associated with the attraction of a romantic partner than testosterone is.

Title: An Evolutionary Psychological Theory of the Personality Structure Underlying Integrity.
Integrity is a highly desirable trait in all kinds of leaders, from politicians to work place managers. However, as Palanski and Yammarino (2007) already noted a decade ago, the scientific understanding of integrity is hampered by three problems: an abundance of definitions, lack of theory, and lack of solid, empirical studies. Despite some limited progress there still is no consensus regarding the exact definition and operationalization of integrity. Thus, Palanski and Yammarino’s critical comments on the literature are still applicable today. Our goal is to address the three challenges above. (1) We use knowledge derived from the personality psychology literature to systematically review the various definitions and operationalizations of integrity within the HEXACO model. Based on this classification we develop a new definition of integrity. (2) We use theoretical evidence from evolutionary game theory to triangulate the appropriateness of this definition. We argue that integrity, as measured by existing instruments, consists of two main components: being predictable (i.e., word-action consistency) and being an active, unconditional cooperator. These are mainly captured by the Conscientiousness and Honesty-Humility traits. (3) We test our predictions in an empirical study. Our findings support our theory and helps resolve several scientific puzzles regarding integrity. For instance, whether integrity is a moral or amoral construct.

Title: Two Ways to the Top, One Way Down: Dominance-Based Leaders Inspire Reverse Dominance Hierarchies
Abstract: Recent research has documented the effectiveness of two leadership strategies – dominance and prestige – for obtaining social rank, attention, and influence. In the current research (five studies; N = 1262) we test the stability of these strategies for maintaining rank and influence. Study 1 measured individual differences in self-reported dominance and prestige for the purpose of creating groups led by either dominance- or prestige-oriented leaders. We observed a positive relationship between dominance and the formation of reverse hierarchies. Study 2, a laboratory experiment, used a simple economic game to manipulate a core feature of dominance versus prestige based leadership – selfishness. Faced with a leader who exploited their role for personal gain, followers quickly lost trust in the leader and banded together to institute a coup. Study 3 used a cross-sectional approach to identify a relationship between employees’ perceptions of their bosses use of dominance/prestige-based tactics, and the extent to which those employees engaged in gossip about their leader. Study 4 used an online experiment to conceptually replicate Study 3 and identified the role of trust as a mediating mechanism between leader strategy and preferences for private communication with other followers. Study 5 used an experimental design to show that dominance- versus prestige-based leaders experience lower levels of trust from followers, which increases the likelihood that followers will seek private channels of communication, which is in turn positively related to attempts to initiate a leadership coup. Taken together, these studies indicate that dominance and prestige may indeed be two ways to the top, but that dominant leaders are less likely to remain at the top over time.

Title: Effective Religious Leadership: Can leader-characteristics predict the vitality of religious communities?
Religious leaders are considered to be of great importance within their religious communities. Due to a lack of empirical data concerning the characteristics and functioning of religious leaders, it is not yet possible to define and identify the factors predicting effective religious leadership. Nevertheless, two recent studies suggest personality to be a predictor of effective religious leadership as Christian leaders working in increasing ecclesial contexts (i.e. church plants) appear to differ from leaders working in decreasing ecclesial contexts (i.e. more traditional churches) with regard to personality characteristics (Foppen, Paas, and van Saane, 2017; 2018).
In this meeting, we want to present our current project on effective religious leadership that, in the wake of our previous pilot studies, aims to carry out a thorough, large-scale, quantitative research to investigate possible predictors of effective religious leadership.
