Episode 70: Coincidence or Synchronicity? You Be The Judge

Have you heard that president Abraham Lincoln had a secretary named Kennedy and president John F. Kennedy had a secretary named Lincoln? In this episode of The Psych Files we explore strange coincidences like this one and we also examine Carl Jung's concept of Synchronicity. Does it mean that everything happens for a reason – or is the idea more complex than that? Let’s find out. Oh and by the way – turns out Lincoln never had a secretary named Kennedy. Don’t believe me? Find out more in this episode of The Psych Files.


  • Correction: I said in the podcast that it would take only a group of 23 people for you to find someone with your birthday. This is incorrect. Thanks to Doug and Leen for emailing me to remind me that I should have said that it would take only 23 people to find two people in the group who had the same birthday. (Note: this has been corrected in the audio as of 9/11/08)
