In our commentariat there is a widely held belief that the only people who fear IRS audits are tax cheats.

If you actually apply the worldview of Matts Fuller and Yglesias, African Americans are disproportionately tax cheats. That seems unlikely to me, and I don’t think the Matts would say that. But the Government Accountability Office recently noted research concluding that “Black taxpayers are audited at higher rates than taxpayers of other races” and that African Americans are disproportionately likely to lose their audits.
