Studies of victim number effects in charitable giving consistently find that people care more and help more when presented with an appeal to help an individual compared with an appeal to help multiple people in need. Across three online experiments ( N = 1,348), Bayesian estimation revealed the opposite pattern when people responded to multiple appeals to help targets of different sizes (1, 2, 5, 7, and 12). In this joint evaluation context, participants donated more to larger groups, when appeals were presented in both ascending order (Study 1) and random order (Study 2). The pattern held whether or not participants saw an overview of all appeals at the start of the study and when a single individual was added to the array (Study 3). These results clarify how compassion fade findings typical of separate evaluations may not generalize to contexts in which people encounter multiple appeals within a short temporal window.

In Experiment 5 of Albarracín et al. (2008), participants primed with words associated with action performed better on a subsequent cognitive task than did participants primed with words associated with inaction. A direct replication attempt by Frank, Kim, and Lee (2016) as part of the Reproducibility Project: Psychology (RP:P) failed to find evidence for this effect. In this article, we discuss several potential explanations for these discrepant findings: the source of participants (Amazon’s Mechanical Turk vs. traditional undergraduate-student pool), the setting of participation (online vs. in lab), and the possible moderating role of affect. We tested Albarracín et al.’s original hypothesis in two new samples: For the first sample, we followed the protocol developed by Frank et al. and recruited participants via Amazon’s Mechanical Turk ( n = 580). For the second sample, we used a revised protocol incorporating feedback from the original authors and recruited participants from eight universities ( n = 884). We did not detect moderation by protocol; patterns in the revised protocol resembled those in our implementation of the RP:P protocol, but the estimate of the focal effect size was smaller than that found originally by Albarracín et al. and larger than that found in Frank et al.’s replication attempt. We discuss these findings and possible explanations.

This article identifies a set of behavioral indicators associated with the carrying of concealed and unholstered handguns. Using qualitative data collected from interviews and focus groups with veteran law enforcement, we outline a variety of cues that, when used appropriately, can help authorities identify people who may be concealing handguns. This work provides a systematic means of assisting the police in identifying and safely interdicting persons who might pose a threat to police or the public. The cues described here contribute to a lexicon that may also serve law enforcement communication, training, and research.

Violent conflict in the Middle East has forced millions to flee their homes and seek refuge in host nations around the globe. Across three studies, we asked American participants (N ∼ 1,500) to consider a refugee-resettlement policy that would bring displaced families from the Middle East into their communities, and tracked the items of information these Americans were interested in seeing during the consideration of their decision. Results suggest that participants who rejected the resettlement policy were especially concerned with security-related information and uninterested in humanitarian-related information, while participants who supported the policy expressed interest in a more balanced ratio of security and humanitarian-related information. We situate these findings within the broader literature on attitude-confirming behaviour (e.g. conformation bias, selective exposure) and discuss how information spotlighting might exacerbate polarization on politically charged issues like refugee policy.

This article identifies and describes a set of behavioral indicators associated with illegal drug carrying in public spaces. Through the use of focus group data, our research documents and translates the visual search techniques that veteran law enforcement and drugs experts report using in their work. Here, we catalogue these findings into 10 overarching categories, and discuss how each indicator may be incorporated into an officer’s visual search. Knowledge of these indicators, when combined with proper training and an understanding of a public space, can help law enforcement identify persons who may be carrying drugs. The ability to identify drug-carrying individuals facilitates the interdiction and apprehension of offenders, and also protects the civil rights and liberties of the law-abiding public.
