I find those tests kind of interesting and were in fact highly involved in the matter during my education in 2012 as a consultant for social and family affairs. I then dug into this theme quite intensely. Have you heard of Gregory Bateson?

While there is a tendency showing in the tests which can be very accurate in prediction it nevertheless will not predict anything where a human being behaves differently. That's the point where it gets interesting for me. It's not so much the prediction and the foreseeable but "chance" or paradoxes or other phenomena.
