Commercial · The free trial that becomes indispensable, The freemium model illustrates the Partial Decision on an industrial scale. A software vendor does not open the conversation with price: it offers free, immediate use. The user imports their files, builds their dashboards, connects their colleagues. By the time the paid version is proposed, the decision is no longer "buy or not" but "lose or keep" an environment already woven into daily life. The cost of giving up, invisible at the start, has become the real selling point, without any pressure ever being applied.
Political · The sticker before the sign: Freedman and Fraser (1966), The founding experiment took place in California. Researchers asked homeowners to place on their lawn a large, unsightly "Drive Carefully" sign. Approached directly, only 17% agreed. But another group had, two weeks earlier, consented to a tiny gesture: displaying a small road-safety sticker. In that group, 76% accepted the sign. This innocuous first commitment had reshaped their self-image as "committed citizens", making later refusal inconsistent. The demonstration remains the empirical proof of the technique.
Diplomatic · Rákosi's salami slice, The expression "salami tactic" is attributed to the Hungarian leader Mátyás Rákosi to describe the post-war communist seizure of power: neutralising the opposition slice by slice rather than all at once, each step seeming too minor to warrant a joint reaction. Transposed to diplomacy, the logic holds: first secure a cordial agreement in principle, then attach increasingly binding commitments to it. No stage seems to cross a red line, but their sum redraws the balance of power without ever offering a visible walk-away point.
Judicial · The graduated admission, In plea negotiation, an investigator or an opposing lawyer rarely seeks the full confession outright. They first obtain acknowledgement of a peripheral, innocuous fact ("you were indeed there that evening"), then a second, then a third. Each admission, seemingly inconsequential, draws the person into a narrative from which it becomes costly to backtrack without appearing inconsistent. This is precisely why legal practitioners recommend conceding nothing on detail before having gauged the overall trajectory.
Corporate · The pilot that becomes the standard, Management wishes to roll out a new reporting tool across the whole organisation, but anticipates massive resistance. Rather than imposing the change globally, it launches a voluntary pilot on a single team, presented as reversible. The pilot "succeeds", the managers have contributed to it, some defended it in meetings. Extending the tool then becomes no longer a contested decision but the logical continuation of a collective commitment already made. The limited first yes has produced its own internal advocates.
Everyday life · The curfew that slips, A teenager never asks head-on for total freedom. They obtain one exception: coming home an hour later "just for this evening". The next time, the exception becomes a benchmark: "last time it was allowed". Stage by stage, the curfew shifts without any single request having seemed unreasonable. The parent, anxious not to contradict themselves from one time to the next, discovers too late that the sum of the exceptions has quietly redefined the rule, domestic incrementalism in all its mechanics.
