Prosocial and cultural change
[Prosocial](https://www.prosocial.world/) is “a change method based on evolutionary science to enhance cooperation and collaboration for groups of all types and sizes that’s effective at a global scale.”
It combines [Elinor Ostrom’s insights about the behaviors of effective groups](https://en.wikipedia.org/wiki/Elinor_Ostrom#Design_principles_for_Common_Pool_Resource_(CPR)_institution) with evolutionary science and [theories of change](https://contextualscience.org/act)–moving toward or away from goals, with visible and internal reactions–that can make existing groups more effective.
Prosocial was used to [fight Ebola in Sierra Leone](https://www.prosocial.world/post/combating-the-ebola-epidemic-in-sierra-leone-with-prosocial), where the facilitators worked with local people to create a new way of honoring the dead that didn’t cause more infections; and to [design a new community park in Detroit](https://www.prosocial.world/post/prosocial-gives-a-boost-to-detroits-viola-liuzzo-park-project).
