My research area concerns the use of psychometric measures in leadership development. I am looking in to the subjective experience, reactions and interpretations arising when leadership development-participants take tests. Moreover, I will explore the rationale behind using them; how their usage is legitimized and why they are considered valuable and necessary. Overall, I am questioning the contemporary inclination to measure and quantify ever more aspects of our lives, by shedding light on to the implications for the individual and leadership development practices.
