YouTube video by Jasss Journal How Multiple Leadership and Flattened Status Structures Affect Cooperation in Task Groups

What happens when small task groups have multiple #leaders instead of one? New insights from #evolutionary #gametheory and #ABM reveal the trade-offs between clarity, #cooperation, and #status.
