“ Intuition is magical, but it’s not reserved for a couple of people,” said Laura Lynne Jackson, 46.

She’s from Commack, N.Y., and makes her living as a psychic medium, and she was talking to hundreds who attended this year’s In Goop Health Summit in New York City (tickets start at $1,000) who were there to learn how to tap into their inner intuition. “It’s for all of you,” she said.

Ms. Jackson, who was joined by four other professional “intuitives” at the event (which also featured speakers like medical doctors, nutritionists and C.E.O.s), is one of several new mediums entering the growing industry of self-care.

While psychics have traditionally profited from claiming to predict the future or communicating with deceased relatives, many are now working in the general field of wellness, calling themselves “intuitives” or “intuitive healers,” who channel “energy” that helps people discover what they want out of life.

“A majority of the mediums that we work with are less interested in the party trick of showing off their psychic abilities and more focused on teaching people, women in particular, how to trust their guts and lean into their intuition,” Noora Raj Brown, the senior vice president of communications at Goop, wrote in an email.
