This is how social scientists should act. The Social Science Research Council has set up the website Understanding Katrina: Perspectives from the Social Sciences. SSRC explains:
"As analyses and "spin" of the Katrina crisis grow, we confront the sort of public issue to which a social science response is urgently needed. Accordingly, the SSRC has organized this web forum addressing the implications of the tragedy that extend beyond "natural disaster" "engineering failures," "cronyism" or other categories of interpretation that do not directly examine the underlying issues—political, social and economic—laid bare by the events surrounding Katrina."
