As she died in a Washington hospital in 1997, Jeane Dixon reportedly uttered five last words: I knew this would happen. It was a fitting exit for a woman who built a global empire on the premise that she could see the future. This deep dive decodes the mechanics of belief that made millions follow her.

We track her bizarre trajectory from real estate executive to trusted confidant of U.S. presidents, and examine the cognitive bias named in her honor.

• Her fabricated crystal-ball origin story versus her real Wisconsin birth as Lydia Emma Pinckert, and years of lying about her age.
• Her career as president of a Washington real estate firm alongside her psychic persona.
• The 1956 Parade magazine prediction linked to Kennedy, and how followers ignored her later reversal.
• Her political access, from advising on counter-terrorism policy to the circle around Nancy Reagan.
• The Jeane Dixon effect, her long list of failed predictions, and the confirmation bias that sustained her.
