Weapon Effects and Individual Intent to do Harm: Influences on the Escalation of Violence

In order to assess the roles of weapons and offender intentions in the outcomes of potentially violent events, researchers analyzed more than 2,000 incidents described by offenders. Findings indicate that weapons have independent effects that differ across the stages of an event. The investigation advances the study of weapons effects through a within-person analysis that lets us control for all time-stable characteristics of the offenders. Thus, researchers address the concern that relationships between type of weapon and incident outcome may be spurious because individuals with a greater propensity to do harm are more likely to use guns.
