Were you given the same or a different test?
My test involved vode/veani (imaginary body lotion) and words like good/bad, joy/agony, wonderful/awful. Same form I guess with different subjects. They asked before the results if I thought that I had a preference.
Looking back on my results I see that I showed a strong preference for one on the first test and then a mild preference on the next two tests.
I found them from a reference in a book published in 2005. They have been testing since 1998 and have completed 4.5 million tests. I am fairly certain that they are legitimate. I have been contacted 3 times to repeat the test.
