Yale psychiatrist Albert Powers didn’t know what to expect as he strolled among the tarot card readers, astrologers, and crystal vendors at the psychic fair held at the Best Western outside North Haven, Connecticut, on a cloudy November Saturday in 2014.
At his clinic, Powers worked with young people, mostly teenagers, who had started hearing voices. His patients and their families were worried that the voices might be precursors of psychosis such as schizophrenia. Sometimes, they were. But Powers also knew that lots of people occasionally heard voices — between 7 and 15 percent of the population, according to studies — and about 75 percent of those people lived otherwise normal lives.
