Synchronicity is the experience of two or more events which occur in a meaningful manner, but which are causally unrelated. In order to be synchronous, the events must be related to one another conceptually, and the chance that they would occur together by random chance must be very small.



The concept of synchronicity

The idea of synchronicity is that the conceptual relationship of minds, defined by the relationship between ideas, is intricately structured in its own logical way and gives rise to relationships which have nothing to do with causal relationships in which a cause precedes an effect. Instead, causal relationships are understood as simultaneous — that is, the cause and effect occur at the same time.


Synchronous events reveal an underlying pattern, a conceptual framework which encompasses, but is larger than, any of the systems which display the synchronicity. The suggestion of a larger framework is essential in order to satisfy the definition of synchronicity as originally developed by Swiss psychologist Carl Jung.

Carl Gustav Jung coined the word to describe what he called "temporally coincident occurrences of acausal events."


Jung variously described synchronicity as an "'acausal connecting principle'" (i.e., a pattern of connection that cannot be explained by conventional, efficient causality), "meaningful coincidence" and "acausal parallelism". Jung introduced the concept in his 1952 paper "Synchronicity — An Acausal Connecting Principle", though he had been considering the concept for almost thirty years.[1]

It was a principle that Jung felt gave conclusive evidence for his concepts of archetypes and the collective unconscious [2], in that it was descriptive of a governing dynamic that underlay the whole of human experience and history — social, emotional, psychological, and spiritual.

Jung believed that many experiences perceived as coincidence were not merely due to chance but, instead, suggested the manifestation of parallel events or circumstances reflecting this governing dynamic. [3]

One of Jung's favorite quotes on synchronicity was from Through the Looking-Glass by Lewis Carroll, in which the White Queen says to Alice:

"It's a poor sort of memory that only works backwards". [4]

Events that happen which appear at first to be coincidence but are later found to be causally related are termed Incoincident.



A well-known example of synchronicity is the true story of the French writer Émile Deschamps who in 1805 was treated to some plum pudding by the stranger Monsieur de Fortgibu. Ten years later, he encountered plum pudding on the menu of a Paris restaurant, and wanted to order some, but the waiter told him the last dish had already been served to another customer, who turned out to be de Fortgibu.


Many years later, in 1832, Émile Deschamps was at a diner, and was once again offered plum pudding. He recalled the earlier incident and told his friends that only de Fortgibu was missing to make the setting complete — and in the same instant the now senile de Fortgibu entered the room.[5]

A mother is working at preparing her dinner, and thinks "It would be nice to have some flowers here today," while her son is in the garden picking flowers for her dinner. The mother has never had flowers on the dinner table before, and the son has never brought flowers, but their close relationship leads them to both originally create the same idea at the same time.

Simultaneous discovery, the creation of the same new idea at causally disconnected places by two persons at approximately the same time. It is very difficult to account for simultaneous discovery by random chance. If for example an American and a British musician, having never had anything to do with one another, arrived at the same musical concept, chord sequence, feel or lyrics at the same time in different places, this is an example of synchronicity. This is explained by reasons such as global culture, which is the larger framework required to fit the definition of synchronicity.

During production of The Wizard of Oz, a coat bought from a second-hand store for the costume of Professor Marvel was later found to have belonged to L. Frank Baum, author of the children's book upon which the film is based. [6]

The Wizard of Oz and Pink Floyd are part of the alleged Dark Side of the Rainbow synchronicity.




A recent study within the Princeton Engineering Anomalies Research Lab (the PEAR lab), suggested that there is a small, though statistically measurable, link between human thought and patterns that occur in random data sets.


There is no evidence as to whether this is caused by individuals unintentionally recognizing complex patterns and then molding their thoughts towards an unconsciously known result or the thoughts of the individual are themselves affecting the random patterns in a manner of individuation. This study's results have not been replicated, and its methodologies are disputed.[7]


The PEAR lab closed at the end of February, 2007, after conducting 28 years of research on the relationships and interactions between Mind and Matter.



According to Occam's razor, positing an underlying mechanism for meaningfully interpreted correlations is an unsupported explanation for a "meaningful coincidence" which may be explained by simple coincidence.


Jung and followers believe that Synchronous events such as simultaneous discovery happen far more often than random chance would allow, even after accounting for the sampling bias inherent in the fact that meaningful coincidences are noticeable while meaningless coincidences are not.

This has the same effect as that described in this article, and it is one of John Constantine's more unusual tricks, and part of what makes him so dangerous. He is also seen doing this in Books of Magic, the graphic novel by Neil Gaiman.

  • The phenomenon is also explored, though not named, in "The Red Notebook" by Paul Auster, and is considered a major theme of his entire bibliography, appearing in some form in almost every work.

  • In the 1983 release Synchronicity by The Police (A&M Records), bassist Sting is reading a copy of Jung's Synchronicity on the front cover along with a negative/superimposed image of the actual text of the synchronicity hypothesis. A photo on the back cover also shows a close-up but mirrored and upside-down image of the book. There are two songs titled "Synchronicity I" and "Synchronicity II" included in the album. The latter song contrasts the dangerous breakdown of a desperate family man with the simultaneous emergence of a menacing something from the bottom of a dark Scottish loch.

  • In the D20 Modern roleplaying game Urban Arcana, Synchronicity is a magic spell that subtly rearranges reality, allowing the subject to avoid the minor inconveniences and hassles of everyday life. While the spell is in effect, buses and trains run on time, stoplights and crosswalk signals change in your favor just as you approach an intersection, and the flow of street traffic and pedestrians will allow you to proceed unimpeded, without hurry or delay. Waiters and clerks will approach as soon as they are wanted, and depart when you desire privacy. Taxi cabs, elevators, vacant parking spaces, and so forth will similarly be available wherever and whenever needed. This spell is particularly helpful when the subject is chasing someone or is trying to escape pursuers.

  • Terence McKenna used the term 'Cosmic giggle' to mean "a randomly roving zone of synchronicity and statistical anomaly. Should you be caught up in it, it will turn reality on its head. It is objective and subjective, simultaneously 'really there' and yet somehow is sustained by imagination and expectation...." [9]

      'Well, I don't want any TO-DAY, at any rate.'
      'You couldn't have it if you DID want it,' the Queen said. 'The rule is, jam to-morrow and jam yesterday--but never jam to-day.'
      'It MUST come sometimes to "jam to-day,"' Alice objected.
      'No, it can't,' said the Queen. 'It's jam every OTHER day: to-day isn't any OTHER day, you know.'
      'I don't understand you,' said Alice. 'It's dreadfully confusing!'
      'That's the effect of living backwards,' the Queen said kindly: 'it always makes one a little giddy at first--'
      'Living backwards!' Alice repeated in great astonishment. 'I never heard of such a thing!'

    • A lot o' people don't realize what's really going on. They view life as a bunch o' unconnected incidents 'n things. They don't realize that there's this, like, lattice o' coincidence that lays on top o' everything. Give you an example; show you what I mean: suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconsciousness.
