Synchronicity (German: Synchronizität) is a concept, first introduced by analytical psychologist Carl Jung, which holds that events are "meaningful coincidences" if they occur with no causal relationship yet seem to be meaningfully related.[1] During his career, Jung furnished several different definitions of it.[2] Jung defined synchronicity as an "acausal connecting (togetherness) principle," "meaningful coincidence", and "acausal parallelism." He introduced the concept as early as the 1920s but gave a full statement of it only in 1951 in an Eranos lecture.[3]
In 1952 Jung published a paper "Synchronizität als ein Prinzip akausaler Zusammenhänge" (Synchronicity – An Acausal Connecting Principle)[4] in a volume which also contained a related study by the physicist and Nobel laureate Wolfgang Pauli,[5] who was sometimes critical of Jung's ideas.[6] Jung's belief was that, just as events may be connected by causality, they may also be connected by meaning. Events connected by meaning need not have an explanation in terms of causality, which does not generally contradict the Axiom of Causality.
Jung used the concept in arguing for the existence of the paranormal.[7] A believer in the paranormal, Arthur Koestler wrote extensively on synchronicity in his 1972 book The Roots of Coincidence.[8] The idea of synchronicity as extending beyond mere coincidence (as well as the paranormal generally) is widely rejected in the academic and scientific community.

Jung coined the word "synchronicity" to describe "temporally coincident occurrences of acausal events." In his book Synchronicity: An Acausal Connecting Principle, Jung wrote:[9]
How are we to recognize acausal combinations of events, since it is obviously impossible to examine all chance happenings for their causality? The answer to this is that acausal events may be expected most readily where, on closer reflection, a causal connection appears to be inconceivable.In the introduction to his book, Jung on Synchronicity and the Paranormal, Roderick Main wrote:[10]
The culmination of Jung's lifelong engagement with the paranormal is his theory of synchronicity, the view that the structure of reality includes a principle of acausal connection which manifests itself most conspicuously in the form of meaningful coincidences. Difficult, flawed, prone to misrepresentation, this theory none the less remains one of the most suggestive attempts yet made to bring the paranormal within the bounds of intelligibility. It has been found relevant by psychotherapists, parapsychologists, researchers of spiritual experience and a growing number of non-specialists. Indeed, Jung's writings in this area form an excellent general introduction to the whole field of the paranormal.In his book Synchronicity: An Acausal Connecting Principle, Jung wrote:[9]
...it is impossible, with our present resources, to explain ESP, or the fact of meaningful coincidence, as a phenomenon of energy. This makes an end of the causal explanation as well, for "effect" cannot be understood as anything except a phenomenon of energy. Therefore it cannot be a question of cause and effect, but of a falling together in time, a kind of simultaneity. Because of this quality of simultaneity, I have picked on the term "synchronicity" to designate a hypothetical factor equal in rank to causality as a principle of explanation.Synchronicity was a principle which, Jung felt, gave conclusive evidence for his concepts of archetypes and the collective unconscious.[11] It described a governing dynamic which underlies the whole of human experience and history — social, emotional, psychological, and spiritual. The emergence of the synchronistic paradigm was a significant move away from Cartesian dualism towards an underlying philosophy of double-aspect theory. Some argue this shift was essential to bringing theoretical coherence to Jung's earlier work.[12][13]
Even at Jung's presentation of his work on synchronicity in 1951 at an Eranos lecture, his ideas on synchronicity were evolving. On Feb. 25, 1953, in a letter to Carl Seelig, the Swiss author and journalist who wrote a biography of Albert Einstein, Jung wrote, "Professor Einstein was my guest on several occasions at dinner. . . These were very early days when Einstein was developing his first theory of relativity [and] It was he who first started me on thinking about a possible relativity of time as well as space, and their psychic conditionality. More than 30 years later the stimulus led to my relation with the physicist professor W. Pauli and to my thesis of psychic synchronicity."[4]
Following discussions with both Albert Einstein and Wolfgang Pauli, Jung believed there were parallels between synchronicity and aspects of relativity theory and quantum mechanics.[14]
Jung believed life was not a series of random events but rather an expression of a deeper order, which he and Pauli referred to as Unus mundus. This deeper order led to the insights that a person was both embedded in a universal wholeness and that the realisation of this was more than just an intellectual exercise, but also had elements of a spiritual awakening.[15] From the religious perspective, synchronicity shares similar characteristics of an "intervention of grace". Jung also believed that in a person's life, synchronicity served a role similar to that of dreams, with the purpose of shifting a person's egocentric conscious thinking to greater wholeness.
Examples
In his book Synchronicity Jung tells the following story as an example of a synchronistic event:
My example concerns a young woman patient who, in spite of efforts made on both sides, proved to be psychologically inaccessible. The difficulty lay in the fact that she always knew better about everything. Her excellent education had provided her with a weapon ideally suited to this purpose, namely a highly polished Cartesian rationalism with an impeccably "geometrical" idea of reality. After several fruitless attempts to sweeten her rationalism with a somewhat more human understanding, I had to confine myself to the hope that something unexpected and irrational would turn up, something that would burst the intellectual retort into which she had sealed herself. Well, I was sitting opposite her one day, with my back to the window, listening to her flow of rhetoric. She had an impressive dream the night before, in which someone had given her a golden scarab — a costly piece of jewellery. While she was still telling me this dream, I heard something behind me gently tapping on the window. I turned round and saw that it was a fairly large flying insect that was knocking against the window-pane from outside in the obvious effort to get into the dark room. This seemed to me very strange. I opened the window immediately and caught the insect in the air as it flew in. It was a scarabaeid beetle, or common rose-chafer (Cetonia aurata), whose gold-green colour most nearly resembles that of a golden scarab. I handed the beetle to my patient with the words, "Here is your scarab." This experience punctured the desired hole in her rationalism and broke the ice of her intellectual resistance. The treatment could now be continued with satisfactory results.[16]The French writer Émile Deschamps claims in his memoirs that, in 1805, he was treated to some plum pudding by a stranger named Monsieur de Fontgibu. Ten years later, the writer encountered plum pudding on the menu of a Paris restaurant and wanted to order some, but the waiter told him that the last dish had already been served to another customer, who turned out to be de Fontgibu. Many years later, in 1832, Deschamps was at a dinner and once again ordered plum pudding. He recalled the earlier incident and told his friends that only de Fontgibu was missing to make the setting complete – and in the same instant, the now-senile de Fontgibu entered the room.[17]
Jung wrote, after describing some examples, "When coincidences pile up in this way, one cannot help being impressed by them – for the greater the number of terms in such a series, or the more unusual its character, the more improbable it becomes."[18]
Wolfgang Pauli
In his book Thirty Years That Shook Physics – The Story of Quantum Theory (1966), George Gamow writes about Wolfgang Pauli, who was apparently considered a person particularly associated with synchronicity events. Gamow whimsically refers to the "Pauli effect", a mysterious phenomenon which is not understood on a purely materialistic basis, and probably never will be. The following anecdote is told:
It is well known that theoretical physicists cannot handle experimental equipment; it breaks whenever they touch it. Pauli was such a good theoretical physicist that something usually broke in the lab whenever he merely stepped across the threshold. A mysterious event that did not seem at first to be connected with Pauli's presence once occurred in Professor J. Franck's laboratory in Göttingen. Early one afternoon, without apparent cause, a complicated apparatus for the study of atomic phenomena collapsed. Franck wrote humorously about this to Pauli at his Zürich address and, after some delay, received an answer in an envelope with a Danish stamp. Pauli wrote that he had gone to visit Bohr and at the time of the mishap in Franck's laboratory his train was stopped for a few minutes at the Göttingen railroad station. You may believe this anecdote or not, but there are many other observations concerning the reality of the Pauli Effect! [19]
Relationship with causality
Causality, when defined expansively (as for instance in the "mystic psychology" book The Kybalion, or in the platonic Kant-style Axiom of Causality), states that "nothing can happen without being caused." Such an understanding of causality may be incompatible with synchronicity. Other definitions of causality (for example, the neo-Humean definition) are concerned only with the relation of cause to effect. As such, they are compatible with synchronicity. There are also opinions which hold that, where there is no external observable cause, the cause can be internal.[20]It is also pointed out that, since Jung took into consideration only the narrow definition of causality – only the efficient cause – his notion of "acausality" is also narrow and so is not applicable to final and formal causes as understood in Aristotelian or Thomist systems.[21] The final causality is inherent[22] in synchronicity (because it leads to individuation) or synchronicity can be a kind of replacement for final causality; however, such finalism or teleology is considered to be outside the domain of modern science.
Explanations
Religion
Many people believe that the Universe or God causes synchronicities. Among the general public, divine intervention is the most widely accepted explanation for meaningful coincidences.[7] Faith in something Greater provides them with a cause.Mathematics
Jung and his followers (e.g., Marie-Louise von Franz) share in common the belief that numbers are the archetypes of order, and the major participants in synchronicity creation.[23]This hypothesis has implications that are relevant to some of the “chaotic” phenomena in nonlinear dynamics. Dynamical systems theory has provided a new context from which to speculate about synchronicity because it gives predictions about the transitions between emergent states of order and nonlocality.[24] This view, however, is not part of mainstream mathematical thought.Quantum Physics
According to a certain view, synchronicity serves as a way of making sense of or describing some aspects of quantum mechanics. It argues that quantum experiments demonstrate that, at least in the microworld of subatomic particles, there is an instantaneous connection between particles no matter how far away they are from one another. Known as quantum non-locality or entanglement, the proponents of this view argue that this points to a unified field that precedes physical reality.[25] Continuity (non-locality) along one dimension is then correlated with discontinuity (locality) along the other dimension[What does this mean?] of this field. As with archetypal reasoning, the proponents argue that two events can correspond to each other (e.g. particle with particle, or person with person) in a meaningful way.Synchronicity can also be seen in David Bohm's theory of implicate order. According to Bohm's[26] theory, there are three major realms of existence: the explicate (unfolded) order, the implicate (enfolded) order, and a source or ground beyond both. The flowing movement of the whole can thus be understood as a process of continuous enfolding and unfolding of order or structure. From moment to moment there is a rhythmic pulse between implicate and explicate realities. Therefore, synchronicity would literally take place as the bridge between implicate and explicate orders, whose complementary nature define the undivided totality.
Probability theory
Mainstream mathematics argues that statistics and probability theory (exemplified in, e.g., Littlewood's law or the law of truly large numbers) suffice to explain any purported synchronistic events as mere coincidences.[27][28] The law of large numbers, for instance, states that in large enough populations, any strange event is arbitrarily likely to happen by mere chance. However, some proponents of synchronicity question whether it is even sensible in principle to try to evaluate synchronicity statistically. Jung himself and von Franz argued that statistics work precisely by ignoring what is unique about the individual case, whereas synchronicity tries to investigate that uniqueness.Among some psychologists, Jung's works, such as The Interpretation of Nature and the Psyche, were received as problematic. Fritz Levi, in his 1952 review in Neue Schweizer Rundschau (New Swiss Observations), critiqued Jung's theory of synchronicity as vague in determinability of synchronistic events, saying that Jung never specifically explained his rejection of "magic causality" to which such an acausal principle as synchronicity would be related. He also questioned the theory's usefulness.[29]
Psychology
In psychology and cognitive science, confirmation bias is a tendency to search for or interpret new information in a way that confirms one's preconceptions, and avoids information and interpretations that contradict prior beliefs. It is a type of cognitive bias and represents an error of inductive inference, or is a form of selection bias toward confirmation of the hypothesis under study, or disconfirmation of an alternative hypothesis. Confirmation bias is of interest in the teaching of critical thinking, as the skill is misused if rigorous critical scrutiny is applied only to evidence that challenges a preconceived idea, but not to evidence that supports it.[30]Likewise, in psychology and sociology, the term apophenia is used for the mistaken detection of a pattern or meaning in random or meaningless data.[31] Skeptics, such as Robert Todd Carroll of the Skeptic's Dictionary, argue that the perception of synchronicity is better explained as apophenia. Primates use pattern detection in their form of intelligence,[32] and this can lead to erroneous identification of non-existent patterns. A famous example of this is the fact that human face recognition is so robust, and based on such a basic archetype (essentially two dots and a line contained in a circle), that human beings are very prone to identify faces in random data all through their environment, like the "man in the moon", or faces in wood grain, an example of the visual form of apophenia known as pareidolia.[33]
It has also been argued that Jungian psychology's theory of synchronicity is equivalent to intellectual intuition.[34]
