The following personality test was developed by Aperture scientists in the late seventies as a way to determine test subject compatibility for cooperative testing initiatives. The test was categorized UNSAFE by Aperture Laboratories in 1977, after every test subject who took the test became immediately insane from having so many unassailable truths and gut-wrenching personal secrets about themselves revealed at once. The test was placed in a locked strong box and secured in an abandoned sub-basement. This sub-basement was then filled with cement, and the doorway bricked over.Upon rediscovery of the document last month, Aperture scientists felt the results were "inconclusive." A further round of testing has been requested. And you can help!
