Why Do People Think Individuals in Poverty Are Less Vulnerable to Harm?: Testing the Role of Intuitions About Adaptation.

People often falsely believe that individuals from low socioeconomic status (SES) backgrounds are less harmed than those from higher SES backgrounds by a wide range of negative events. We report three studies (total N = 1,625) that provide evidence that this "thick skin bias" emerges at least in part because people overgeneralize otherwise accurate intuitions about adaptation. Across studies, participants accurately intuited that people adapt to psychophysical experiences (e.g., brightness, weight, and volume) but also inaccurately intuited that people similarly adapt to life hardships that actually tend to exacerbate the harm of future negative events. Experimentally decreasing the salience of psychophysical adaptation intuitions reduced the thick skin bias, suggesting a causal link between these adaptation intuitions and the belief that people in poverty are less vulnerable to harm and underlining the importance of studying how biased beliefs about the effects of poverty may perpetuate inequality.
