Hypothetically, if a colleague has repeatedly demonstrated the utter lack of reading comprehension skills (like pulling the same door labelled “push” for the hundredth time), what job could one suggest for them where this “disability” wouldn’t be detrimental?
I bet that’s not too difficult with a Stroop test. A reading brain struggles to ignore names of colours when asked to describe the colour of squares, and the timing difference between coloured squares with correct words and incorrect words should beat anyone who hasn’t put in a lot of effort to train for this.
Alternatively, though it’s probably not legal, you could probably use repeated imprinting of the McCollough effect combined with colour based contrast to make it essentially impossible for any human to read those documents. Staring at a set of McCollough images for 15 minutes can actually alter your visual perception for up to three whole months. I’m sure there’s a way this can be weaponised for secure disposal in some ways, although it’s quite an ask for the employees subject to it.
