Basic faults With This Study
I wonder if pop pseudo-psychologists can be identified from their speech patterns?
Even if you ignore the basic silliness of a soft science with an extremely high rate of predictive failure using computer voice patterns as a tool, the pool of test subjects was so small as to make it utterly impossible to get any useful conclusions from this effort.
Those "researchers" need to give a full refund to whomever paid for this study.
BTW when I was a teenager a psychologist predicted I'd have a psychotic break at some time. Unless of course I had a long course of therapy with him. Since I was probably the least aggressive, calmest, most self contained kid in the world my parents just laughed at him. Looks like the overselling of this discipline hasn't changed in the past 50 plus years.
