Additional Trial Information
In this study, we investigate the effect of leadership choice on team performance in non-routine, analytical team tasks. We use a lab-in-the-field setup in which groups of teams work on a non-routine analytical team task to analyze when leadership emerges. The task makes teams
face complex and novel problems, it is analytical and cognitively demanding as teams need to collect and recombine information which requires to think outside the box to succeed, and it is interactive as team members have to collaborate, discuss possible actions, and develop ideas jointly with their team members. Registration Citation
We implement three treatments, one control condition, one where leadership can be formed endogenously and one where we assign leadership exogenously to a team mebmer.
Intervention Start Date
Intervention End Date
Primary Outcomes (end points)
Time until completion, completion rate at 60 minutes
Primary Outcomes (explanation)
Secondary Outcomes (end points)
Number of hints taken, timing at which hints are taken, team member geo distance, team conversation contents, questionnaire answers
Secondary Outcomes (explanation)
We conduct the experiment with our partner in a setting that resembles non-routine and analytical team tasks. Subjects are from the subject pool of the local lab. Treatments are randomized by day over the sampling period to avoid spillover between observations that we record at similar points in time. We record completion time, answers to questionnaire questions, several background characteristics and variables related to the task. Additionally, we record geo distances of players, as well as record their conversations (pending technical feasibility, which we evaluate in the week of July 30, before the start of collecting data).
