Professor Paul Piff is a social psychologist at the University of California, Berkeley. He examines the origins of human kindness and cooperation, and the social consequences of economic inequality.
One of his experiments looked at which drivers stop for pedestrians, depending on the value of the vehicle. He found a correlation between higher value vehicle and their lower likelihood of stopping at pedestrian crossings – despite being legally obliged to do so. Source: BBC News
I haven’t read the research paper and I don’t generally trust clickbait articles. Therefore my thoughts were:
• What thresholds determined a high value and low value vehicle?
• Were cars grouped into certain value groups?
• Were the group sample sizes large and proportionate across groups?
• How many different neighbourhoods and crossings were observed?
• How varied was the sample in terms of observation times?
