Several researchers have tested palmistry's accuracy by having palmists read hands without knowing the subject, then checking predictions against life facts. Results have not exceeded chance. The most methodologically robust studies show that palmistry does not reliably identify personality traits, health history, or future events.
Readings feel accurate for well-documented reasons: the Barnum effect (generic statements feel personal), the cold reading techniques many practitioners use unconsciously, and confirmation bias (we remember the hits and forget the misses).
This does not make palmistry worthless. As a reflective or meditative practice — a structured way to think about one's life, tendencies, and choices — it has real value for many people. That value comes from the reflection, not the prediction.
