In the current study we hypothesized – and found – that coercive interviewing increased the incidences of false accusations made by eyewitnesses. Fifty-nine university students participated in a laboratory study in participant-confederate pairs and were later interviewed about whether the confederate stole a research assistant’s cell phone. Participants interviewed using a Coercive Interview were significantly more likely to falsely accuse the confederate of stealing a cell phone than were participants interviewed using a non-coercive, Control Interview. Our findings raise questions regarding why participants gave false accusations and whether coercive methods could result in more accurate testimony from reluctant witnesses. We suggest the need for potential safeguards, such as the electronic recording of interviews of non-suspect witnesses to prevent or document the use of coercive methods. 相似文献

Climate change sceptics are known for their resistance to proactive climate response policies, especially policies aimed at restricting greenhouse gas emissions. It is often assumed that scepticism about the science behind climate change would lead directly to outright rejection of all proactive climate policies aimed at mitigating emissions and adapting to climate‐induced changes already under way. This article demonstrates the variability among the climate policy views of seven well‐known Australian climate change sceptics in the period 2007–2012. Using the lens of frame‐analysis, we unpack some key sceptic rationales and narratives. The analysis shows that sceptics share a master frame that privileges individualist‐libertarian‐progress‐social order values, which are thus likely to conflict with the values implicit in conventional climate policy remedies. The analysis also shows that sceptical pre‐occupations diverge at more detailed framing levels, with various practical concerns and fears often at the centre of sceptical argumentation 相似文献

We assess the effects of police use of lethal force on subsequent murders by victim race and armed status before and after the August 2014 death of Michael Brown in Ferguson, MO. We regress monthly murder levels on instances of police use of lethal force by race and armed status controlling for fixed effects, population, unemployment, and murders in the prior month using city-level data for 93 cities from 2013 to 2015. For 2013–2015, we find that a police lethal force incident predicts a 1.8% increase in murders 2 months following the incident. However, prior to Ferguson, a police lethal force incident increases murders by 4.5% (after 2 months) and we are unable to find any evidence of differential responses to police use of lethal force based on victim race. However, we find evidence of differential responses to police use of lethal force based on victim armed status. Post-Ferguson, police use of lethal force is associated with significant differential responses based on victim race. In addition, we see a shift in the aggregate-level response to police use of lethal force. Post-Ferguson, a police lethal force incident decreases the murder level by 3.8% 3 months following the incident. In addition, lethal force incident involving a non-black victim decreases the number of murders by 4.3% while an incident involving a black victim increases the number of murders by 2.1% (after a 2-month lag). Changes in policing following the events of Ferguson had a generally positive but uneven effect. 相似文献
