When it comes to psychic readings, there are typically two kinds: cold readings and hot readings. As explained by The Outline, a cold reading is one in which the medium doesn't know anything about the person they are reading, and goes on to make guesses about them based on what they see and hear. A hot reading, however, is when the medium learns about their client ahead of time and can use the information they learn in the reading.
It seems that despite his insistence that he doesn't know much about the celebrities he works with, Henry does use a combination of hot and cold readings with each person with whom he works. Some have pointed out that when Henry relies on a cold reading, he sometimes uses questions that appear personalized but are actually pretty general.
Podcast host Carrie Poppy told The Outline that an example of this would be Henry saying something like, "You almost drowned when you were a kid." Poppy goes on to explain that "A lot of people do almost drown when they're kids. We're not ready for water when we're kids, so it's millions of people," but that if someone believes their own near-drowning was unique, they are more likely to respond to a medium such as Henry with a lot more weight that someone who does not.
