In numerology, some New Age believers often link 11:11 to chance or coincidence. It is an example of synchronicity. For instance, those who are seeing 11:11 on a clock often claim it as an auspicious sign or signaling a spirit presence. Post-hoc reasoning and confirmation bias provides a context for such claims, and skeptics have pointed out that the assertions of people like Uri Geller that 11:11 is somehow important in world events do not hold up to even cursory scrutiny.
