 The trouble is that we have no data about the person's psychic ability prior to the encounter. We have no data points to compare, and these psychic enhancements are difficult to document. In other words, they are self-reported. I asked Barry Greenwood about this because my searches had found little, and he told me, and I quote again, I recall an old story about Daryl Evans, a Detroit Tigers baseball player, claiming that after a UFO sighting, his playing skill improved.
