The Ethics of Influence

Articulate the line between persuasion and manipulation in writing — your own working definition, defensible against the hardest cases. Recognize dark patterns and asymmetric persuasion at scale, both as deployed against you (most days) and, if you build or market anything, as deployed by you (some days). Decide which tools you use deliberately, which only reciprocally, and which you refuse on principle — written down, with at least one concrete change shipped. Dark patterns are anti-patterns with a specific signature: a short-term metric improvement (signups, conversions, time-on-page) purchased with long-term user trust. Once you have the bestiary you see them as clearly as N+1 queries in a view. The morning-after test is the blameless post-mortem applied to product and persuasion decisions: "would the user, six weeks out, with full information, defend the choice we channeled them toward?" And the open-source builder ethic — no surprises, transparent behavior, the user understands what's happening — is the content of ethical persuasion in marketing form; the engineer who wouldn't ship hidden telemetry already has the instincts. Where the lens lies: the engineer's ethical instinct is individualist — it reasons about you and the next user, one at a time. This module's question is partly collective: a persuasive choice defensible in any single case (a small default toggled on) can produce population-level harm at scale. Postman, Zuboff, and Harris reason at the scale where individual intuition stops being sufficient. The individual ethic alone won't carry the load.
