Four rules determined the list
The law already calls the decision consequential. Credit, insurance, employment, housing, health care, essential services, law enforcement and migration are the categories that Colorado's automated decision law, California's rules and the EU AI Act name explicitly. Where the law has drawn a line, a person has a foothold, and we can measure whether it holds.
The decision can be reconstructed from public records. Each of these areas produces documents an outsider can read: adverse action notices, securities filings, device labels, transparency portals, court records, regulator decisions. We do not score what cannot be checked.
Each area tests a different relationship between the machine and the person. A credit model judges the applicant directly. A screening tool decides whether the applicant gets past the door. A clinical tool advises a professional about a patient who may never know. A plate reader watches a driver who signed nothing. A background check remembers a person whether or not the record is right. A method that produces comparable scores across all of these can be trusted on any one of them.
Exit is expensive. People cannot opt out of credit, employment, housing, health care or public roads. A human option matters where leaving is not a real choice; a film recommendation does not qualify.
Five areas, one path
Money
Credit, insurance, payments. The machine decides whether you get funds, a payout or your own balance back. Governed by adverse action law, state insurance codes and user agreements.
Work and housing
Hiring, gig work, renting. The machine gates income and shelter. Governed by anti-discrimination law, fair housing law, consumer reporting law and, in Europe, the data protection rules that fined Uber.
Body
Clinical triage, coverage decisions, reproductive health. The machine advises a professional or an insurer about you. Governed by device regulation, medical records rights and Medicare appeal rules.
Surveillance
Plate readers, enforcement targeting, benefit fraud systems. The machine observes or sanctions people who signed nothing. Governed by constitutional due process, public records law and little else.
Records
Background checks, data brokers, court and eviction records, pretrial risk scores. The machine keeps a file on you and other machines read it. Governed by consumer reporting law and the new data broker deletion rights. This is the fifth area and the second edition: when the file is wrong, what can you do?
