Title of Talk: 

The Significance of Non-Significant Findings: Negative Results from a Randomized Control Trial (RCT) of Patrol Visibility.



Industry preference for significant results can tacitly influence scientists’ research design, statistical analyses, and interpretation of findings.  Discovering what does not work can be crucial to finding out what does, yet these negative findings rarely grace the pages of influential journals.  Authentic scientific objectivity requires a somewhat agnostic orientation to the enterprise of human inquiry.  This perspective is couched in the findings of a recent multi-site randomized controlled trial (RCT) of police patrol visibility.  Visual salience of police patrol vehicles was enhanced utilizing static red and blue emergency lighting.  The experiment tested the efficacy of visual salience in deterring overnight vehicle crime across four jurisdictions in the state of Connecticut.  Primary outcome measures for the intervention (i.e. motor vehicle burglary; car theft) were not statistically significant.  Implications and areas for future research flow from these negative findings.
