Truth 5 in Practice: Ethics Is Engineering

Before: "Move fast and break things." Bias is discovered by users or journalists. Negative externalities are addressed through public relations. Model behavior is opaque and unaccountable. Ethics is a compliance checkbox.

After: "Move fast with moral infrastructure"—ethical review is embedded in design. Bias is detected through internal testing and monitoring before release. Negative externalities are addressed through product and policy change. Model behavior is documented, monitored, and subject to human override. Ethics is a design discipline with dedicated expertise and authority.

Application:

Make ethics a shipping gate. No intelligent system ships without an ethics review with findings, mitigations, and sign-offs.
Test for bias before deployment. Use held-out data. Test protected attributes. If you cannot explain a disparity, you cannot ship.
Build human override into every high-stakes decision.
Publish limitations. Transparency is not a weakness. It is a commitment to accountability.
