Institutions, like organisms, develop immune responses to threats. Like organisms, they sometimes attack themselves.
Institutional Self-Defence
Institutions develop defensive responses to threats — the patterns of behaviour that emerge when the institution's core functions, resources, or legitimacy are challenged. These responses are adaptive when the threat is external and the response protects genuine institutional value. They become pathological when the institution's immune response is triggered by internal challenges to the institution's dysfunctions rather than external challenges to its legitimate functions — when the institution defends its current form against the reformers who are trying to improve its actual performance.
The institutional immune response operates through several mechanisms. Bureaucratic resistance — the accumulation of process requirements, approval stages, and coordination demands around any proposed change — increases the transaction cost of change to the point where the reformer exhausts their resources before the change can be implemented. Reputation management — the informal circulation of concerns about the reformer's judgment, motives, or institutional fit — damages the credibility that the reformer needs to maintain the coalition behind the change. And selective enforcement — the application of institutional rules with greater stringency to actors proposing change than to those defending the status quo — creates asymmetric costs that make reform more expensive than it should be.
When the Immune Response Becomes Autoimmune
The autoimmune institution is the institution whose defensive responses have become directed primarily at its own adaptive mechanisms — at the people and processes that would allow it to respond to changed conditions and improve its performance. These institutions are characteristically very effective at protecting their current form and very ineffective at improving their actual performance, because the immune response that was designed to protect the institution is now protecting the institution's dysfunctions against the changes that would address them.
The indicators of autoimmune institutional behaviour are consistent: the systematic departure of the institution's most capable and innovative members, who find their adaptive contributions treated as threats; the accumulation of process requirements around proposed improvements, which makes improvement increasingly costly; and the progressive narrowing of what is considered within the institution's legitimate purview, which reduces the space for adaptive response to changing conditions.
The institution that cannot be changed from within has turned its immune system against its own adaptive capacity. It will survive in its current form until external pressure becomes sufficient to overcome the immune response — at which point the change will be more disruptive than it would have been if the autoimmune response had not prevented earlier adaptation.
