Antisocial behaviors cause harm, directly or indirectly, to others’ welfare. The novel coronavirus pandemic has increased the urgency of understanding a specific form of antisociality: behaviors that increase risk of disease transmission. Because disease transmission-linked behaviors tend to be interpreted and responded to differently than other antisocial behaviors, it is unclear whether general indices of antisociality predict contamination-relevant behaviors. In a pre-registered study using an online U.S. sample, we found that individuals reporting high levels of antisociality engage in fewer social distancing measures: they report leaving their homes more frequently (p = .024) and standing closer to others while outside (p < .001). These relationships were observed after controlling for sociodemographic variables, illness risk, and use of protective equipment. Independently, higher education and leaving home for work were also associated with reduced distancing behavior. Antisociality was not significantly associated with level of worry about the coronavirus. These findings suggest that more antisocial individuals may pose health risks to themselves and their community during the COVID-19 pandemic.

Brainhack is an innovative meeting format that promotes scientific collaboration and education in an open, inclusive environment. This NeuroView describes the myriad benefits for participants and the research community and how Brainhacks complement conventional formats to augment scientific progress.

Psychopathy is a personality construct characterized by interpersonal callousness, boldness, and disinhibition, traits that vary continuously across the population and are linked to impaired empathic responding to others’ distress and suffering. Following suggestions that empathy reflects neural self–other mapping—for example, the similarity of neural responses to experienced and observed pain, measurable at the voxel level—we used a multivoxel approach to assess associations between psychopathy and empathic neural responses to pain. During fMRI scanning, 21 community-recruited participants varying in psychopathy experienced painful pressure stimulation and watched a live video of a stranger undergoing the same stimulation. As total psychopathy, coldheartedness, and self-centered impulsivity increased, multivoxel similarity of vicarious and experienced pain in the left anterior insula decreased, effects that were not observed following an empathy prompt. Our data provide preliminary evidence that psychopathy is characterized by disrupted spontaneous empathic representations of others’ pain that may be reduced by instructions to empathize.

Brainhack is an innovative meeting format that promotes scientific collaboration and education in an open and inclusive environment. Departing from the formats of typical scientific workshops, these events are based on grassroots projects and training, and foster open and reproducible scientific practices. We describe here the multifaceted, lasting benefits of Brainhacks for individual participants, particularly early career researchers. We further highlight the unique contributions that Brainhacks can make to the research community, contributing to scientific progress by complementing opportunities available in conventional formats.
