the death test will work very well if i design it
it will work acceptably well if it is designed by people who want it to work
and it will fail if it is designed by people who want it to fail
you also fail to realize i don't "know" things - i make them up. it's a perk of being a genius. i wouldn't worry about my ability to design a death test.
i would start by testing those in prison, then illegals, then those on welfare and in nursing homes, then the retirees, then the unemployed, then the chronically ill etc.
by the time i got to testing gainfully employed healthy young people i would figure out how to test properly.
