• Military technology outpaces laws of war

    Today’s emerging military technologies — including unmanned aerial vehicles, directed-energy weapons, lethal autonomous robots, and cyber weapons like Stuxnet — raise the prospect of upheavals in military practices so fundamental that they challenge long-established laws of war. Weapons that make their own decisions about targeting and killing humans, for example, have ethical and legal implications obvious and frightening enough to have entered popular culture (for example, in the Terminator films). The current international laws of war were developed over many centuries and long before the current era of fast-paced technological change.

  • One percent of Swedish criminals commit 63 percent of all violent crimes

    The majority of all violent crime in Sweden is committed by a small number of people. Researchers have examined the case of all the people who were brought up on charges of violent crimes in Sweden between 1973 and 2004 – 2.5 million people in all. Of the 2.5 million individuals included in the study, 4 percent were convicted of at least one violent crime — 93,642 individuals in total. Of these convicted at least once, 26 percent were re-convicted three or more times, thus resulting in 1 percent of the population (23,342 individuals) accounting for 63 percent of all violent crime convictions during the study period.

  • Prolonged viewing of terrorist incident media coverage tied to acute stress

    Stepping away from the television, computer screen or smartphone in the aftermath of terrorist attacks or mass shootings may be beneficial to your mental health. This is the takeaway from a new study showing that six or more daily hours of exposure to media coverage of the Boston Marathon bombings in the week afterward was linked to more acute stress than having been at or near the marathon. Acute stress symptoms increased with each additional hour of bombing-related media exposure via television, social media, videos, print, or radio.

  • Fashion scouts and cops: the logic behind stop-and-frisk

    New research compares practices used by fashion industry casting directors to the New York City Police Department’s controversial stop-and-frisk program. Fashion casting directors belong to a select group of mediators responsible for shaping the pool of modeling talent by scouring familiar territory for the young and beautiful. These casting directors had been similarly indoctrinated into the industry and the talent they would choose often resulted in over-representation of certain kinds of people. Similarly, police officers are a select group responsible for making a city safer. Their training — reinforced daily through the institutionalization and public acceptance of such practices — disposes them to scour familiar geographical and social territory for potential criminals, often resulting in over-representation of people from certain groups.

  • Wrong crowd: social networks are key to city violence

    A new study of gun violence in Chicago reveals that a person’s social network is a key predictor in whether an individual will become a victim of gun homicide, even more so than race, age, gender, poverty, or gang affiliation. “Risk factors like race and poverty are not the predictors they have been assumed to be,” one of the researchers said. “It’s who you hang out with that gets you into trouble. It’s tragic, but not random.”

  • War experiences harden group alliances

    War is hell, and according to new research, experiencing its horrors can cause people to have a greater affinity for members of their own group, particularly if they are exposed to warfare in early adulthood or later in childhood. The researchers say that these effects have the potential to explain why conflict sometimes leads to cycles of war and sometimes stimulates nation-building in its wake.

  • Perspectives on terrorism and responses to it

    The Strategic Multi-Layer Assessment office within the Office of the Secretary of Defense has published a new white paper, in Looking Back, Looking Forward: Perspectives on Terrorism and Responses to It Strategic Multi-layer Assessment, which offers discussions of different perspectives of terrorism and approaches to understanding the phenomenon. The papers cover topics ranging from strategic and adaptive considerations of terrorism to analytical considerations.

  • Death of Muslims used by extremists for recruitment, propaganda

    In the last thirty years, conflicts in Afghanistan, Iraq, Bosnia, Chechnya, Somalia, and other countries have caused the death of four million Muslims. The theme of innocent Muslims dying as result of conflicts initiated by Western powers and their allies is a central motif used by Islamic militants to recruit new members. It is a theme which fuels anti-American sentiments in the Middle East and North Africa. Historians and Islamic scholars note that the notion that the West is orchestrating a “genocide” of Muslim is patently false, and that beginning with the Iran-Iraq War (1980-88) and continuing to the present day, more and more casualties are inflicted by Muslims against Muslims. Still, the myth of a non-Muslim genocidal “crusade” against Muslims is powerful, and is one which is effectively used by al Qaeda and other Islamic terrorist groups.

  • Psychologists: psychology research should promote peace and nonviolence

    Political psychologists argue that psychology’s contributions can extend beyond understanding the origins and nature of violence to promoting nonviolence and peace. In a paper, they say they oppose the view that war is inevitable and argue that understanding the psychological roots of conflict can increase the likelihood of avoiding violence as a way to resolve conflicts with others.

  • Societies with rigid cultural values produce more terrorists

    Examining more than 80,000 terrorist attacks which occurred between 1970 and 2007, researchers find that cultural values and norms which promote rigid thinking are related to a greater number of terrorist attacks or fatalities. Societies that have the belief that one’s destiny and life events are predetermined (fatalism), have very strong norms and severe punishments for deviation from norms (cultural tightness), and those that privilege masculinity and have very distinct gender roles (low gender egalitarianism) have higher terrorism rates than those that are low on these dimensions.

  • Violent hate crimes, lone-wolf terrorism share characteristics

    Researchers examined the timing, locations, methods, targets, and geographic distributions of lone-actor terrorist attacks, group-based terrorist attacks, and violent hate crimes that occurred in the United States between 1992 and 2010. They found that locations where the 101 lone-actor terrorism incidents occurred shared more demographic similarities with the locations of the 46,000 violent hate crimes than with the locations of 424 group-based terrorist attacks over the time period.

  • DHS finds no racial profiling at Logan Airport

    An August 2012 allegation of racial profiling by Transportation Security Administration (TSA) officers sparked an investigation into the screening practices of TSA officers at Logan International Airport. DHS has recently concluded an investigation into allegations, and concluded that there was no evidence that TSA officers in Boston have been targeting minorities for additional screening to meet quotas.

  • The arithmetic of gun control and gun violence

    The most comprehensive statistical study of gun violence in the United States – examining data going back to the First World War – finds that, in more common domestic and one-on-one crimes, reduced legal gun availability, if properly enforced, is likelier to lower deaths. In rare mass shootings, armed citizens might save lives if sufficiently trained to avoid accidentally shooting fleeing bystanders. The authors note, though, that key parts of their equations should be studied more closely: the fraction of offenders who illegally possess a gun, the statistical degree of protection provided by legal gun ownership, and the number of people who are legally carrying a gun when attacked. Comprehensive data in those areas, they say, could further aid the development and implementation of effective policies.

  • Research priorities for understanding public health aspects of gun-related violence

    A new report from the Institute of Medicine (IOM) and National Research Council (NRC) proposes priorities for a research agenda to improve understanding of the public health aspects of gun-related violence. The committee which wrote the report said significant progress can be achieved in three to five years through a research program that addresses five high-priority areas: the characteristics of gun violence, risk and protective factors, prevention and other interventions, gun safety technology, and the influence of video games and other media.

  • Overconfident, introverted people more likely to be e-mail phishing victims

    New study shows that people who are overconfident, introverted, or women are less able accurately to distinguish between legitimate and phishing e-mails. Phishing is the use of fraudulent e-mail correspondence to obtain passwords and credit card information, or to send viruses.
