These reforms are based on evidence that citizen perceptions of police legitimacy are more strongly affected by officers' adherence to procedural fairness than their ultimate enforcement decisions. However, this evidence rests on a narrow operationalization of citizen outcomes defined as arrests or citations, overlooking a wide range of intrusive actions shown to affect citizens' perceptions of police but rarely recorded in administrative police data. We reevaluate the assumed primacy of officer communication over citizen outcomes using detailed annotations of more than 1,500 body-worn camera recordings covering 917 Los Angeles Police Department traffic stops. We construct a stop-level measure of procedural justice and compare it to a new measure of stop intensity: the cumulative intrusiveness of discretionary officer action within an interaction. We show that Black and Hispanic drivers experience substantially more intense stops than White drivers; this gap persists after conditioning on stop context and citizens' escalatory behavior during a stop. We also show, counter to prevailing wisdom, that stop intensity predicts perceived legitimacy as strongly as procedural justice. Our findings underscore the utility of expanding currently narrow measures of citizen outcomes in assessment of police-citizen interactions, and that reforms intended to enhance police legitimacy should also address intrusive police behavior rarely captured in administrative enforcement data.</p></div><br>Social Sciences Lab<br><div><br></div></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Mon, Oct 12, 2026 at 10:17 AM Social Sciences Laboratory <<a href="mailto:ssl@ucr.edu">ssl@ucr.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Dear Social Science Community,<br><br>This is a friendly<span> </span>reminder<span> </span>about the first lunch talk of our Fall series!
