Within the depth-psychology corpus, 'coincidence' occupies a precisely charged conceptual position: it is simultaneously the empirical starting-point and the theoretical problem. Jung's foundational move is to distinguish mere statistical coincidence — events falling within the bounds of calculable probability — from 'meaningful coincidence,' the technical designation for synchronistic events whose inner-outer conjunction exceeds what chance alone can plausibly account for. This distinction drives the entire synchronicity literature. Jung and von Franz both insist that the causal framework of natural science, while adequate for sequential events, breaks down before the phenomenon of meaningful coincidence because the psychic relativization of space and time dissolves the preconditions for cause-and-effect. Von Franz extends this into cosmological territory, linking acausal orderedness to negentropy, archetypes, and the creatio continua. Wilhelm's I Ching foreword, rendered by Jung, offers the Chinese worldview as a counterpoint: where Western science dismisses coincidence, the Chinese mind regards it as the primary datum of inquiry. Masters raises a cautionary counter-voice, warning that the wholesale denial of coincidence can collapse into egocentric magical thinking and spiritual bypassing. The tension between these poles — coincidence as noise versus coincidence as signal — constitutes the central epistemic drama of the corpus.

synchronicity takes the coincidence of events in space and time as meaning something more than mere chance, namely, a peculiar interdependence of objective events among themselves as well as with the subjective (psychic) states of the observer
Jung's canonical definition of synchronicity is articulated precisely against the concept of mere coincidence, upgrading it to 'meaningful coincidence' by positing a psychophysical interdependence irreducible to causality.
Jung, Carl Gustav, Psychology and Religion: West and East, 1958thesis
Just as causality describes the sequence of events, so synchronicity to the Chinese mind deals with the coincidence of events... The synchronistic view on the other hand tries to produce an equally meaningful picture of coincidence.
Jung's foreword to the I Ching establishes meaningful coincidence as the structural counterpart to causality, presenting Chinese cosmology as the historical matrix for a synchronistic rather than causal reading of simultaneous events.
Wilhelm, Richard, The I Ching or Book of Changes, 1950thesis
Just as causality describes the sequence of events, so synchronicity to the Chinese mind deals with the coincidence of events... The synchronistic view on the other hand tries to produce an equally meaningful picture of coincidence.
Identical in content to the Wilhelm passage, this version confirms the canonical formulation linking synchronicity to the Chinese mind's preoccupation with simultaneous coincidence over sequential causation.
Richard Wilhelm, Cary F. Baynes, The I Ching or Book of Changes, 1950thesis
Independence of time and space brings about a concurrence or meaningful coincidence of events not causally connected with one another... The characteristic feature of all these phenomena... is meaningful coincidence, and as such I have defined the synchronistic principle.
Jung identifies 'meaningful coincidence' as the defining feature and formal definition of the synchronistic principle, encompassing telepathy, clairvoyance, precognition, and psychokinesis under a single acausal concept.
Jung, Carl Gustav, Mysterium Coniunctionis: An Inquiry into the Separation and Synthesis of Psychic Opposites in Alchemy, 1955thesis
spontaneous, meaningful coincidences of so high a degree of improbability as to appear flatly unbelievable... the causal explanation, the only possible one from the standpoint of natural science, breaks down owing to the psychic relativization of space and time
Jung argues that certain high-improbability coincidences resist causal explanation because the psychic relativization of space-time undermines the preconditions for the cause-effect relation itself.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
What we call coincidence seems to be the chief concern of this peculiar mind, and what we worship as causality passes almost unnoticed.
Von Franz, citing Jung's commentary on the I Ching, positions coincidence as the primary epistemological category of Chinese thought, in direct contrast to the causal preoccupation of Western science.
von Franz, Marie-Louise, Psyche and Matter, 2014thesis
the highly improbable coincidence of the inner and outer three tigers in this woman's life seems to have no common cause, and therefore it inevitably struck her as 'more than mere chance' and somehow as 'meaningful.'
Von Franz illustrates synchronistic coincidence through a clinical vignette in which an archetypal dream image and an improbable external event (three tigers) converge acausally, producing the phenomenological experience of meaning.
von Franz, Marie-Louise, Psyche and Matter, 2014supporting
The suspicion that this must be a case of meaningful coincidence, i. e., an acausal connect
Jung's fish-symbol diary entry serves as an empirical illustration of how clusters of thematically linked events accumulate into what he designates meaningful coincidence, exceeding the plausibility of mere chance.

I noted the following on April 1, 1949: Today is Friday. We have fish for lunch. Somebody happens to mention the custom of making an 'April fish' of someone.
Jung's detailed account of the fish-coincidence series demonstrates empirically the clustering structure of meaningful coincidences, building the case that their concatenation defies a purely probabilistic explanation.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960supporting
synchronistic events form only momentary special instances in which the observer stands in a position to recognize the third, connecting element, namely the similarity of meaning in the inner and outer events.
Von Franz distinguishes synchronistic coincidences from the broader category of acausal orderedness, characterizing them as episodic events in which meaning — the tertium comparationis — bridges inner psychic state and outer occurrence.
von Franz, Marie-Louise, Psyche and Matter, 2014supporting
something has happened that shows all the signs of synchronicity, namely a 'meaningful coincidence' or 'Just So' story. Obviously the ancients must have experienced the same thing quite by chance, otherwise no such tradition could ever have arisen.
Jung reflects on his astrological experiment, concluding that its unexpectedly confirmatory result was itself a synchronistic event — a meaningful coincidence — and that the astrological tradition was similarly founded on such acausal experiences.
Jung, C.G., Collected Works Volume 18: The Symbolic Life, 1976supporting
such a coincidence should occur at all is so improbable and so incredible that nobody could have dared to predict anything like it... What seems in fact to have happened... is that we got a result which has presumably turned up many times before in history.
Jung interprets the statistically improbable result of his astrological experiment as itself a synchronistic coincidence, shaped by the emotional and archetypal conditions present during the investigation.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960supporting
One has the impression that these methods, and others like them, create favourable conditions for the occurrence of meaningful coincidences.
Jung suggests that mantic procedures such as astrology and the I Ching function as structured contexts that catalyze the emergence of synchronistic, meaningful coincidences.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960supporting
I wanted to present a case of 'meaningful coincidence' which would illustrate the main idea of my paper on synchronicity. This fact has been generally overlooked.
Jung clarifies that his astrological experiment was designed not to validate astrology but to demonstrate a case of meaningful coincidence illustrating the synchronicity principle, a point he feels critics have systematically misread.
Jung, C.G., Collected Works Volume 18: The Symbolic Life, 1976supporting
they nearly always occur in the region of archetypal constellations, that is, in situations which have either activated an archetype or were evoked by the autonomous activity of an archetype.
Jung identifies activated archetypes as the consistent psychological substrate underlying synchronistic coincidences, grounding the phenomenon in depth-psychological conditions rather than random occurrence.
Jung, C.G., Collected Works Volume 18: The Symbolic Life, 1976supporting
no one has yet succeeded in constructing a causal bridge between the elements making up a meaningful coincidence.
Jung marks the epistemological limit of causal explanation before meaningful coincidence, establishing that the bridge between psychic state and external event remains, in principle, acausal.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960supporting
Naturally such coincidental events all have their own causal connections; only the coincidence itself is to be understood acausally.
Von Franz draws a precise methodological distinction: each element in a synchronistic event has its own causal history, but the coincidence of the elements — their simultaneous meaningful conjunction — is by definition acausal.
von Franz, Marie-Louise, Psyche and Matter, 2014supporting
for them there is no such thing as a meaningless accident... That which the modern scientist evaluates strictly as an accident, the primitive will always try to fathom the meaning of.
Von Franz situates the concept of meaningful coincidence within a cross-cultural frame, arguing that pre-modern and indigenous peoples maintain a synchronistic worldview in which no coincidence is devoid of meaning.
von Franz, Marie-Louise, Psyche and Matter, 2014supporting
The outcome of the complete test proved to be a highly improbable but definitely a chance result. It was, however, a meaningful chance result, that is, a synchronistic event, but not the statistically tested regularity which he had hoped for.
Von Franz concludes that Jung's astrological results, while statistically inconclusive, were themselves a synchronistic event — a meaningful coincidence — demonstrating that synchronicity cannot be captured by statistical regularity.
von Franz, Marie-Louise, Psyche and Matter, 2014supporting
Those of us who are heavily invested in signs are usually possessed by the belief that there are no such things as coincidences and that 'everything happens for a reason.'
Masters offers a critical counter-position, warning that the reflexive denial of coincidence and the compulsive search for meaning in every event can signal magical thinking and the egocentrism characteristic of spiritual bypassing.
Masters, Robert Augustus, Spiritual Bypassing When Spirituality Disconnects Us From, 2012supporting
no subsequent event proved the importance of this miraculous coincidence, which cannot therefore be counted for by what lay in the future.
Freud's treatment of a premonitory dream coincidence illustrates the pre-Jungian engagement with the phenomenon, framing it as a 'miraculous coincidence' whose significance resists standard causal or predictive explanation.
Freud, Sigmund, The Interpretation of Dreams, 1900aside
there is an obvious simultaneity between the flock of birds, in its traditional meaning, and the death of the husband.
Jung presents a clinical anecdote in which a symbolic event (flock of birds) coincides with a death, examining whether unconscious constellation in the observer mediates the apparently acausal simultaneity.

the receptor acts as a coincidence detector. It allows calcium ions to flow through its channel if and only if it detects the coincidence of two neural events, one presynaptic and the other postsynaptic.
Kandel's neurobiological use of 'coincidence detector' for the NMDA receptor provides a technical scientific counterpoint, showing that coincidence as simultaneous event-detection has an established place in physical science independent of meaning.
