Even worse, voters had only ten minutes to complete the three-page, 30-question document. And yet, as the instructions state, “one wrong answer denotes failure of the test,” an impossible standard for even a legitimate exam. The test here from Louisiana consists of questions so ambiguous that no one, whatever their level of education, can divine a “right” or “wrong” answer to most of them. For example, the Veterans of the Civil Rights Movement describes a test administered in Alabama that is so entirely subjective it measures the registrar’s shrewdness and cunning more than anything else. Yet they were “in actuality disproportionately administered to black voters.” Additionally, many of the tests were rigged so that registrars could give potential voters an easy or a difficult version, and could score them differently as well. These tests, writes Rebecca Onion at Slate, were “supposedly applicable to both white and black prospective voters who couldn’t prove a certain level of education” (typically up to the fifth grade).
