Method synopsis

Analysis of citizen behavioral responses to government security threat level changes using polling data and government resource usage statistics. Used correlation and linear modeling to assess habituation effects.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Natural security: a darwinian approach to a dangerous world (2008). Implementations in other papers (listed below) may differ.

1. Collect polling data on terrorism worry
   Obtained CNN/USA Today/Gallup polling data from www.pollingreport.com/terror.htm asking 'How worried are you that you or someone in your family will become a victim of terrorism: very worried, somewhat worried, not too worried, or not worried at all?'
   Quantities: Approximately 1000 Americans surveyed periodicallyDuration: Periodic surveys since 9/11Conditions: Not specified
   Equipment: polling surveys
2. Collect DHS website and phone usage data
   Obtained data from DHS summarizing number of hits to the DHS Web site (www.Ready.gov) and calls to the DHS information line (1-800-BE-READY)
   Quantities: Website page views and phone call counts by monthDuration: Monthly data collectionConditions: Not specified
   Equipment: web analytics, phone system logs
3. Analyze response patterns
   Used bivariate correlations to examine how public responses changed over time and as a function of specific DHS threat levels, then fitted general linear models to isolate the effect of DHS threat level after accounting for variation explained by date
   Quantities: Data from November 2001 through approximately 2004Duration: Multi-year analysis periodConditions: DHS threat levels remained at either level 3 (elevated) or level 4 (high)
   Equipment: statistical analysis software

Typical Equipment
