US police officers’ knowledge regarding behaviors indicative of deception: Implications for eradicating erroneous beliefs through training

Abstract

The current study surveyed a random sample of Texas law enforcement officers (n?=?109) about their knowledge regarding behaviors indicative of deception. The officers were not highly knowledgeable about this topic, overall performing at a chance level in assessing how various behavioral cues relate to deception. Confidence in one's skill was unrelated to accuracy, and officers who reported receiving the most training and utilizing these skills more often were more confident but no more accurate in their knowledge of the behaviors that typically betray deception. The authors compare these results to previous studies that have examined officers’ beliefs in other countries and discuss the implication of these results in terms of developing future training programs that may debunk the common misconceptions that officers possess.     

A Poisson model of incidents of international terrorism in the United States

Abstract

Various haphazard, and often uncoordinated, efforts have been devoted to discouraging and combatting terrorism. Unfortunately, there has been a noticeable lack of quantitative studies of the problem of terrorism. Nevertheless, it can be expected that the problem of international terrorism will eventually be a focus for operations researchers. A factor fundamental to any OR study is an understanding of the underlying generating process for incidents of terrorism. Based on incidents of terrorism from 1968 to 1974, this paper notes that the Poisson is a good model for the occurrence of incidents of international terrorism in the United States. Results of both chi‐square and Kolmogorov‐Smirnov tests are presented. Finally, an unusual result, inconsistent with popular beliefs, is noted.     

The Effects of Uncontested Elections on Legislator Performance

Political competition lies at the core of representative democracy. Yet, uncompetitive elections and uncontested races are widespread in the United States, particularly at the state level. In this article, we analyze the consequences of uncontested elections on lawmaking activity. Our primary hypothesis is that legislators who run unopposed are less active lawmakers than those who were selected through competitive elections. Studying roll‐call vote participation and bill introduction and enactment for most of the U.S. states for 1999–2000, we find that state legislators elected in unopposed elections perform more poorly compared to their colleagues elected in competitive contests.
