Over eighty years ago Dr. Robert S. Hartman made a unique discovery. Of course, it was just a theory at first. Then, after forty years of research, it was a mathematically proven science. His research was even nominated for a Nobel Prize in 1973. The discovery was that people all over the world make their decisions through three core decision making dimensions. The are; Intuitive, Practical and Systemic. Knowing how your candidate or current employees are hard wired to value these dimensions, plus how well they 'see' these dimensions will reveal their future performance.
