Equality by lot

Washington state is having a Climate Assembly.

While the rhetoric around the assembly is by now standard, the sortition methodology employed is interesting, and notably includes video documentation (above, starting about 11 minutes in) of the randomization process.

The WA Climate Assembly called 6,333 households via Random Digit Dialing (RDD) recruiting using a longtime RDD sample provider, Scientific Telephone Samples, for RDD sample development. These samples are based on assigned numbers (for landline) or billing zip codes (for cellphone) to ensure the numbers we targeted were within the target market for this assembly.

Once call recipients who were willing and able RSVP’ed to the WA Climate Assembly team, a volunteer team (Panelot) from Carnegie Melon University and Harvard University used an algorithm they developed to generate a list of 10,000 panel compositions. Each one of these panel compositions had a mix of 80 potential Assembly members that reflected the make-up of Washington State, including:

• Approximately half men/women
• Age range from 16+
• Congressional district
• Income level
• Race/ethnicity
• Education level
• A range of opinions backed by earlier studies about whether global warming is happening; is caused mostly by human activities; and whether the individual is worried about global warming.
