Revulsion
Revulsion is the mirror image of euphoria. Where euphoria prices assets above fundamental value because optimism has overwhelmed analysis, revulsion prices assets below fundamental value because pessimism has overwhelmed analysis with equal force. Kindleberger documented the symmetry across every mania he studied. The downward overshoot is typically as severe as the upward overshoot, driven by the same psychological mechanisms operating in reverse. The rhetorical transformation of a repricing into an 'apocalypse' — the 'SaaSpocalypse' narrative — is characteristic of the phase in which the language of participants shifts from measured analysis to hyperbolic catastrophism.
In the AI Story
Revulsion serves a structural function in the financial cycle: it purges speculative excess, destroys the weakest participants, and creates the conditions for a more sustainable allocation of capital. This is cold comfort to the participants being purged, who experience the structural function as personal catastrophe. The SaaS industry will not die during the revulsion phase. It will be repriced with the same brutal indiscrimination that characterized the critical stage, and the companies whose value was always above the code layer will eventually be distinguished from those that were always just code — but not before the revulsion has run its course.
The historical precedent is instructive. The 'dot-bomb' narrative of 2001 was as wrong about the internet as the 'SaaSpocalypse' narrative is wrong about software. The internet was not dead in 2001. Amazon was not finished. Google was not irrelevant. The technologies that emerged from the wreckage — cloud computing, social media, mobile platforms — were vastly more valuable than the pre-crash companies. The crash did not invalidate the displacement. It invalidated the financial superstructure erected upon it.
Kindleberger's structural irony recurs with full force during revulsion: the interventions that would be most effective are countercyclical measures during euphoria, which are the most politically costly. The interventions that are most politically feasible are reactive measures during revulsion, which are the least effective because the damage is already done. The institutional architecture must be built to operate countercyclically — absorbing excess during euphoria and releasing support during revulsion. The AI cycle has produced no such structures.
Origin
The term revulsion derives from medical terminology — the body's violent rejection of a foreign substance — and Kindleberger preserved this clinical connotation. The framework built on earlier crisis literature but gave the overshoot mechanism a more precise formulation.
Key Ideas
Symmetrical overshoot. Downward excess mirrors upward excess, driven by the same mechanisms in reverse.
Apocalyptic rhetoric. Participants adopt hyperbolic language that misreads repricing as extinction.
Structural function. Revulsion purges excess and creates conditions for recovery, at the cost of the participants who bear it.
Countercyclical failure. The intervention window closes before policy can act.
