Steady state frequencies of aggressive individuals , passive individuals , fighting pairs, , and police as a function of the proportion of policing individuals .

Assuming policing interventions (A) we observe a threshold value of police above which conflict is effectively eradicated. Under pacifying interventions (B), conflict declines monotonically in the proportion of pacifiers. For these figures we have used parameter values: . The parametric sensitivity of these results are indicated analytically in the text.
