Modern systems can absorb error for a time. Beliefs drift from consequence. Confidence replaces accuracy. Nothing appears to break.
But the system is still changing.
Delusion at Scale traces how thinking loses its corrective function, how error becomes insulated, and how belief systems stabilize and spread. What begins at the individual level expands into groups, institutions, and entire systems, reshaping how people interpret reality and respond to it.
This is not a story of sudden collapse. It is a pattern of gradual misalignment, where disagreement becomes conflict, maintenance is neglected, and decline is absorbed without recognition.
Until it isn't.
When limits return, they do not adjust to belief. They do not respond to interpretation. They enforce.
This book does not argue. It describes.
Because reality does not negotiate.
