The National Academy of Sciences, Engineering, and Medicine panel recommends checking election results using "risk-limiting audits," invented by Prof. Philip B. Stark.
Risk-limiting audits are endorsed by the American Statistical Association, the Presidential Commission on Election Administration, the League of Women Voters, Verified Voting, and other election integrity groups. Colorado was the first state to require risk-limiting audits, which are also in law in California and Rhode Island, and have been tested in Indiana, Ohio, Virginia, and Denmark. Prof. Stark serves on the Board of Advisors of the U.S. Election Assistance Commission.
