Markets synthesize beliefs — stories and expectations about the future — and aggregate them into present-day prices. They are like religions that accumulate tension. Except instead of discharging tension via sacrifice, you get catastrophic busts. A bubble that can be seen as a bubble rapidly deflates — a clear view of the inner workings is itself a sign of crisis in the system.
Simple Picture
You do not want the stock because you analyzed its fundamentals. You want it because someone you admire owns it. They own it because someone they admire owned it. Nobody in the chain wanted the stock for its own sake. They wanted what others wanted — and the wanting itself became the value. This is Girard’s mimetic desire applied to capital markets: the object has no intrinsic pull. The pull comes from the model — the person whose desire you are imitating.
Markets as Mimetic Systems
René Girard’s central insight: human desire is not autonomous. We desire what others desire, mediated through models whose wanting makes the object desirable. The snob crystallizes this:
The snob is also an imitator. He slavishly copies the person whose birth, fortune, or stylishness he envies… The snob does not dare trust his own judgment, he desires only objects desired by others. That is why he is the slave of the fashionable.
This is desire transplanted from the interpersonal to the financial. In relationships, mimetic desire pulls you toward whoever mirrors your deepest wound — you mistake the intensity for destiny. In markets, mimetic desire pulls you toward whatever asset is rising fastest — you mistake the momentum for fundamental value. Both are wanting what others want and confusing the mimetic pull for an independent judgment.
premium-mediocrity is the consumption version: the $7 latte is desired not for its taste but because it is the object of desire of the class you aspire to join. The reflexive loop makes it structural: the desire creates the demand that creates the price appreciation that confirms the desire.
Bubbles and Legibility
Bubbles increase legibility. A story gathering momentum is easier to believe than one petrified into history. As the bubble grows, it threatens incumbent stories and increasingly becomes a pure bet on revolution — the new narrative against the old. The bubble converts ambiguity into certainty, which is exactly what legibility does: it makes the world readable at the cost of making it fragile.
Every bubble begins with something real — a genuine technological shift, a real demographic trend, a legitimate innovation. The mimetic process then inflates the real signal into a fiction. More and more money follows investors less and less worthy of emulation. Exaggeration becomes the only way to keep the company alive. The real insight is buried under layers of mimetic amplification until the original signal is unrecoverable.
Leverage as Mimetic Accelerant
Leverage introduces a powerful temptation toward mimetic behavior because it gives the hope of catching up. Without leverage, the gap between your portfolio and the model’s portfolio is a discrete barrier — you cannot close it with the capital you have. Leverage dissolves that barrier. Previously impossible imitation becomes possible, and mimetic targets multiply.
This is ergodicity weaponized: leverage converts a strategy that might compound over decades (time-average thinking) into one that must perform now (ensemble-average thinking). The leveraged investor is not making a bet on value — they are making a bet that the mimetic process will continue long enough for them to exit before the bust. They are playing Russian roulette with the number of chambers determined by how long the bubble lasts.
The Passive Paradox
Quantitative investors may have many observations — momentum persists, carry predicts returns, small-caps outperform, price-to-book mean reverts. But in another sense, the quant has many theories and no underlying theory. The observations are empirical regularities with no causal model.
More striking: passive strategies represented $4 trillion in US equities by 2018. All these investors are crowded into a single trade — the bet against stock selection. This is mimetic consensus at institutional scale: the entire industry imitating the same decision not to decide. The alpha efficiency lens reveals an irony: mimetic traders who move with the crowd for private reasons leak less signal than contrarians, meaning conformism can be strategically superior to independence. The priesthood dynamic applies: passive investing is orthodoxy maintained by consensus, and the consensus itself makes it self-reinforcing — until it doesn’t.
The quantitative evidence confirms this: high price-to-sales stocks — the ones surrounded by narrative momentum — consistently disappoint, while cheap, boring stocks that nobody writes about outperform. PSR is “an almost perfect measure of popularity,” and popularity is just mimetic desire measured in dollars.
Mimesis causes ownership distributions to homogenize. Bubble believers and bubble skeptics sort into opposing camps. This adds artificial stability to legacy companies (everyone owns the index) and artificial volatility to challengers (concentration of speculative capital). The market’s apparent stability is manufactured by the very mimetic process that will eventually shatter it. The mimetic gradient generalizes this beyond finance: wherever efficient gradient-following operates — markets, ideology, civilizational consensus — it eliminates the independent actors who serve as shock absorbers, so the stability preceding collapse is produced by the very homogenization that makes the collapse catastrophic.
Dimwit / Midwit / Better Take
The dimwit take is “bubbles are caused by irrational greed — smart investors avoid them.”
The midwit take is “bubbles are rational — each individual is making a reasonable bet that the music won’t stop on their watch.”
The better take is that bubbles are not caused by irrationality or by rationality but by mimesis — the structural tendency to want what others want, which produces a self-reinforcing loop that no individual can see from inside because their own desire feels autonomous. The person in the bubble does not feel like they are imitating anyone. They feel like they have independently discovered something valuable — and the discovery feels independent precisely because the mimetic mediation is invisible. Anonymity breaks mimetic conflict because there is nothing to compete against. The quant who automates decisions removes the model from the loop. But the quant is still inside a larger mimetic structure — the structure of the market itself.
Main Payoff
The deepest connection between Girard and markets: sacrifice. Traditional religions discharge accumulated mimetic tension through ritual sacrifice — a scapegoat absorbs the community’s violence and the system resets. Markets have no ritual mechanism. The tension accumulates until the bust, which functions as an uncontrolled sacrifice — wealth is destroyed, careers are ended, and the system resets. The bust is not a malfunction. It is the structural equivalent of the sacrifice that the market, lacking ritual, has no other way to perform. The Cultural Revolution was this mechanism at civilizational scale — mimetic contagion without a ritual container, the social body attacking itself. Graeber’s history of debt deepens this: the earliest words for debt are synonymous with guilt and sin, and the violence that emerges during market crises is the same violence that always underlies quantified human relations.
