“Nearly two dozen states — among them California, Massachusetts and New York — publish online lists on state websites revealing the identities of tax delinquents. We sent letters to 34,344 individuals who were publicly listed as tax delinquents in Kansas, Kentucky and Wisconsin. The lists included detailed information about these individuals, including their full names and addresses. They owed from $250 to $150,000 per person. We divided recipients into two groups. In the first, only the recipient was chosen to get information about an online list of tax delinquents. In the second, the recipient and other people from the same community were given that information.”
