Technically Wrong: Sexist Apps, Biased Algorithms, and Other Threats of Toxic Tech

A catalogue of how the assumptions, demographics, and blind spots of design teams crystallise into products that harm the people they claim to serve — from name-validation forms that reject non-Western characters to algorithms that reinforce racial profiling. Wachter-Boettcher grounds each case in specific, documented product decisions rather than abstract ethics, making the book unusually actionable for practitioners. The argument is not that technology is inherently biased but that the homogeneity and insularity of the teams building it produces predictable failures that could be caught by broader perspectives at the design stage. For product directors, the book makes a concrete business case for diversity that goes well beyond compliance or optics.
