Safety and harm in groups

Measures that catch the harms an average hides: pressure, dependence and abuse.

Moves it sheds light on

Our reading. None of these fields tests a move inside a circle.

  • Welcome all

    Measures pressure to disclose, dependence and the cost of leaving: the failures that welcoming everything has to rule out.

  • Takes part

    Studies a leader’s power over members and when it turns coercive; whether joining in as a participant changes that hasn’t been studied.
