If I know that most people will not be able to pass the test in the time limit given, and I know that privileged citizens will not be given the test at all, why set myself up for accusations of impropriety by not distributing a key? That assumes that racism correlates 100% with extreme stupidity in all other areas. I have not found this to be the case - many brilliant scientists and statesmen have been over-the-top racists.
I have a book called “Games for the Super Intelligent”, published in the late 60s or early 70s, that has hundreds of questions like this in it. The answers are in the back of the book. Most people still can’t solve them, of course, not because they aren’t “super intelligent”, but because they haven’t had the right training. The Louisiana test only has to segregate out the people who haven’t had the “right” training - i.e. the poor and disadvantaged.
So, I’m arguing that the Louisiana legislature could achieve their goal of restricting voting rights perfectly with a test that did have a key, and did have an appearance of objectivity, and that having such an appearance would be valuable to them for (I hope) obvious reasons. I find this far more believable than the idea that every single white person in charge of a voting booth was a cackling, hand-rubbing Klu Klux Klan member, gleefully hand-grading the literacy tests of black citizens as the slavering white citizenry howled accolades. Which is the narrative we’re being asked to accept - that every single person involved in voting was personally complicit - instead of the much simpler proposition that the test was designed to be very difficult, and have an impossible time limit, and that some of the voting officials abused their powers.
@WearySky has posted a link to the original document that supports the position that there was no key. (Kudos to him for that!) This one source, Jeff Schwartz’s account of his single summer in Louisiana, seems to be where every other such claim I can find comes from. However, the person who wrote that document doesn’t claim to have personally witnessed the test being administered or graded, and later in the same document he says:
Yet the courage of the Black community led many determined souls to go to Freedom Schools, learn how to take the test and make no easy mistakes, endure the slights, derision, and stonewalling (and even threats) from white registrars, and come back again and again, more determined than ever to win the right to vote and demonstrate the illegitimacy of the system that kept them from exercising that right.
He goes on to say (and quotes numbers) that Louisiana Black citizens were able to increase their number of votes, which would clearly be impossible if the test could not be passed by anyone dark-skinned. His account is logically inconsistent (must… refrain… from… snark…) if we interpret it as saying there was no key.
And finally, here is the key to the 1963 test. Why would they suddenly stop using one in 1964? It fails Occam’s razor - their goals were achievable while maintaining an appearance of objectivity, and individual judges could (and no doubt did) apply the test unfairly even with a key… which I believe is a more reasonable interpretation of Schwartz’s memoir. If there are no right answers, you can’t train people to answer right, and activists did train people to answer right, according to the same memoir being quoted to support the idea that there was no right answer.
