``Racial Gaps in the Responses to Hurricane Katrina: An Experimental Study''

 

  Abstract

In the media reports and public discourses, Hurricane Katrina was portrayed as a racialized disaster that disproportionately affected blacks. Indeed, one in three victims of Katrina was African American, and in the most damaged areas of New Orleans, this proportion was as high as three in four. In this paper, using an original survey, we show that in the aftermath of Katrina blacks and whites held strikingly polarized views about everything from why victims did not evacuate to the appropriateness of the government response. We also conduct a randomized experiment to explore the effect of media framing on this racial gap. The findings suggest that even subtle image manipulations can make blacks more sympathetic towards their own racial group. Similar ingroup bias is found for gender as well as race, with women showing more sympathy when they see an image portraying a female victim with children. Our statistical analysis demonstrates how to avoid usual parametric assumptions about nonresponse when analyzing survey and randomized experiments. Finally, we discuss the implications of our findings for the political psychology of race. (Last Revised June, 2007)
