Sony had an E.S.P. (extrasensory perception) research laboratory during the period between 1990 and 1998. They carried out experiments and finally confirmed the existence of E.S.P. Subjects could perceive letters or drawings on a sheet of paper that was rolled up or folded into a small size, and placed in their hands or ears. If the lab was still open now with fewer staff and reduced budgets, what kind of experiments would they carry out?
