The standard skeptical argument against astrology runs roughly like this: the planets are too far away to exert any measurable physical influence on human personality or events. The gravitational force of Jupiter on a newborn is smaller than the gravitational force of the delivering physician. Therefore, astrology cannot work, and the appearance of working is explained by cognitive biases — the Barnum effect, confirmation bias, cold reading techniques, and so on.
This argument is largely correct about causation. The planets almost certainly don’t cause your personality traits or your career outcomes through any physical mechanism. The gravitational calculation is accurate. The cognitive bias explanations are real and well-documented.
But the argument is answering the wrong question.
The question it answers is: does astrology cause anything? The question it ignores is: does astrology mean anything? And these are not the same question. They don’t have the same logical structure, they don’t require the same kind of evidence, and dismissing one doesn’t settle the other.
Two Kinds of Connection
There are at least two fundamentally different ways for things to be connected.
The first is causal connection. Event A causes event B when A produces B through some physical mechanism — force, energy transfer, information exchange, chemical reaction. Causes operate across time (A happens before B) and through space (there’s some chain of physical interaction between them). Causation is what science is primarily in the business of investigating.
The second is meaningful connection. Two things are meaningfully connected when they belong together — when understanding one illuminates the other, when they fit into the same pattern, when their co-occurrence isn’t merely accidental even if it isn’t causal. Meaningful connections don’t require physical mechanisms. They require an observer capable of recognizing pattern and significance.
Language works through meaningful connection. The word “river” doesn’t cause rivers. It doesn’t physically interact with water. But it connects to rivers — it means them — and that connection is real, useful, and not reducible to a causal account. When someone says “river,” something happens in your mind that wouldn’t happen if the physical sound waves had a different shape. That’s meaning doing work.
Analogy works through meaningful connection. When a teacher says “the atom is like a tiny solar system,” no one believes the atom causes solar systems or that solar systems cause atoms. The connection is one of structural resemblance — a pattern that repeats at different scales, which is useful for reasoning about one domain when you already understand the other.
Narrative works through meaningful connection. When you tell the story of your life, you connect events that had no causal relationship. You make the job you lost at twenty-three mean the career change that happened at thirty-one. The loss didn’t cause the change in any strict sense — many people lose jobs at twenty-three and never change careers. But it belongs in the story, and the story is how you understand yourself.
Where Divination Lives
Divination systems operate, primarily, in the domain of meaningful connection rather than causal connection. When a BaZi reading says that your Day Master — the element associated with your birth day — is Water, and that Water day masters tend to express a characteristic combination of adaptability and depth, this is a claim about meaning, not about mechanism. The day you were born didn’t cause your adaptability through any physical pathway. But the system is proposing that “Water” meaningfully describes a pattern — that when that description fits, it fits in a way that’s useful for self-understanding.
The same logic applies to tarot, the I Ching, Western astrology transits, and every other interpretive system. The card that appears in a reading doesn’t cause your situation. The hexagram you cast doesn’t cause the decision you’re facing. The claim is that these symbols mean something about where you are — that there’s a connection of pattern, resonance, or correspondence between the symbol and the situation that is worth attending to.
This is a defensible claim. It’s also a testable claim, though not in the way scientific experiments usually test things. The test is whether the connection, once offered, produces useful insight. Whether sitting with the reading generates understanding that genuinely changes how you act. Whether the meaning is real enough to do work.
The Dismissal That Closes Too Much
The problem with the standard causal dismissal of astrology is that it’s designed to close discussion, and it closes too much.
If the criterion for a real connection is causal mechanism, then very large domains of human life turn out not to contain real connections. Metaphors don’t connect. Analogies don’t connect. The plot of a novel doesn’t connect to your life. The way your father handled disappointment doesn’t connect to your relationship patterns (no physical mechanism — just meaning doing its work across time). Dreams don’t connect to anything.
No one actually believes this. People who apply the causal criterion to astrology don’t apply it to these other domains, because the price of applying it consistently would be unlivable — it would mean abandoning most of what makes human experience meaningful.
The implicit position of most intelligent skeptics is therefore something like: causal connections are the only real connections for explaining how the physical world works, but meaningful connections are legitimate in domains that are explicitly interpretive and non-mechanistic. Literature, art, psychotherapy, personal narrative — these can traffic in meaningful connections without failing a causal test, because no one is claiming they operate through physical mechanisms.
The question then becomes: which category does astrology belong to? And that question doesn’t have an obvious answer. If astrology is understood primarily as a predictive system — claiming to know what specific physical events will occur — it’s making causal-territory claims, and the causal critique applies. If it’s understood as an interpretive framework — offering a vocabulary for noticing patterns in experience — it’s making meaning-territory claims, and the causal critique is simply a category error.
Most sophisticated practitioners today hold something like the interpretive position. The question is whether that position is clearly and honestly communicated — especially to people encountering the systems for the first time.
The Problem With Sneaking Causation Back In
There’s a failure mode on the other side of this distinction that’s worth naming directly.
Some practitioners and apps maintain the interpretive framing in theory while sliding back into causal language in practice. “Mercury retrograde is causing communication breakdowns.” “Your Saturn Return will bring hardship.” “The Void of Course Moon means you shouldn’t sign contracts today.” These are causal claims. They’re claiming that a planetary configuration is doing something to events in the world.
If you believe that literal claim — if you genuinely hold that Mercury’s orbital position is physically disrupting email servers and interpersonal communication — then you need to engage with the causal critique, and the causal critique will not go well for you.
But if what you mean is something like “the Mercury retrograde period is a useful frame for noticing communication patterns that might otherwise go unremarked,” then you’re making a meaning claim. You’re proposing a structure of attention. And the question isn’t whether Mercury causes anything; it’s whether the frame produces useful noticing.
The problem is that the causal language is considerably more vivid, more shareable, and more emotionally engaging than the interpretive language. “Mercury retrograde is causing chaos” is a compelling thing to post. “Mercury retrograde is a useful attentional frame for noticing communication patterns” is accurate but dull. The incentives of social media push constantly toward the causal framing, even among people who know better.
This matters because the causal framing changes how people hold the information. A causal claim about Mercury retrograde produces fatalism: something is happening to me that I can’t control. A meaning claim produces agency: here’s a lens I can use, take up or set down as I choose. The difference between those two postures isn’t trivial — it determines whether the system is a tool for navigation or an excuse for passivity.
Meaning Requires an Observer
There’s one more distinction worth drawing, because it gets at something fundamental about how meaning works.
Causal connections exist independently of whether anyone notices them. Gravity pulled the apple before Newton described it. The connection was real before the description.
Meaning connections are different. They require an observer to exist. The word “river” doesn’t mean river in a world without minds. The plot doesn’t connect to your life until you’re the one reading the novel. The I Ching hexagram doesn’t mean anything until someone sits with it and does the work of interpretation.
This doesn’t make meaning connections less real. It makes them real in a different way — constitutively involving the observer. Which means that when a divination reading “works,” part of what’s working is you. Your attentiveness. Your willingness to sit with the image or the statement. Your capacity to recognize pattern. Your honesty about what actually fits and what doesn’t.
The reading provides a frame. You provide the meaning. The system creates conditions; you do the work.
This is a more honest account of what divination actually offers. It’s also, for many people, more empowering than the causal alternative — because it locates agency where agency actually lives. The stars don’t mean your life. You mean your life, using whatever tools help you see it more clearly.

The Productive Middle Ground
The most intellectually honest position on divination is neither “it works through physical mechanisms we haven’t yet discovered” nor “it’s pure cognitive bias with no legitimate function.” It’s something more like: these systems are frameworks for structured attention that operate through meaningful rather than causal connections, and their value depends on how skillfully the practitioner and the person receiving the reading engage with the distinction.
That’s a mouthful, but it’s defensible. It doesn’t require believing in anything supernatural. It doesn’t require pretending that cognitive biases don’t exist. It requires acknowledging that meaning is a real feature of human experience, that frameworks for noticing meaning can be more or less useful, and that ancient systems refined over centuries by close observation of human experience deserve something more than the dismissal that follows from a category error.
The question to ask of any divination reading isn’t “is this caused by the positions of the planets?” It’s “does this frame help me see something I couldn’t see before?” That’s the question that meaning-making tools answer well, when they’re used well.
