In 1940, 400 Chicago prisoners were infected with Malaria in order to test new drugs to fight the disease.  The ethics of this decision are debated to this day.  But this gave the researchers at the asylum an idea.  Sighting test pilots as an example of people choosing to be test subjects of their own free will, they convinced the government to allow them to approach convicts with a proposal.  No reduced sentences could be negotiated, but if the prisoners were willing to subject themselves to the asylum's scientific testing, they would be transferred to a new facility with larger recreation areas.  May not seem like much to us, but to a prisoner, this was quite the incentive.  This deal also had the dual purpose of keeping all the test subjects confined to a single location, preventing them from talking about the experiments with anyone else.  An undisclosed part of the agreement stated that the asylum would take into their care any subject who did not depart the tests unscathed.  Explaining the risks involved, the researchers were able to find 100 willing subjects in less than 30 days.

The Who department got the summaries they needed, and more.  What surprised them was that almost none of the prisoners showed any reaction to the Libri Verum, even when given the complete book to read.  Only 5% showed suicidal tendencies.  Closer examination showed that 7 of the subjects were more illiterate than the researchers had been led to believe, and another 4 were designated of such a low learning capacity, there were categorically retarded.  But what about the others?

Like a morning fog slowly melting away, the answer became clearer and clearer with each examination.
