Tarot cards have no scientific merit. They are interpreted based upon whoever is reading them. I have had several readings as part of a study and found that 99.9% of what was said, was so open it could have happened in any form. I also noted that they never stated anything that wasn't very plausible. I did 50 readings telling them some about me and did 50 readings not telling them a thing. The 50 readings that I did tell them stuff about me, they were able to "predict" what would happen. The other half didn't do so well. I had 15 tell me they couldn't get in touch with their "guides" another group told me I was hard to read, and the others simply made educated guesses. My conclusion is Tarot cards are as accurate as you believe them to be. In reality, they have no merit, and they are nothing more than play toys.
