Sales · Debt collectors: the routine studied by Rafaeli and Sutton, In their field study published in the Academy of Management Journal (1991), Anat Rafaeli and Robert Sutton observed collection agents alternating threat and understanding to secure payment. An agent adopts a hard, pressing tone evoking litigation and penalties, then shifts to a compassionate stance offering an instalment plan "to help". The authors document that this emotional contrast triggers compliance in three ways: fleeing the pressure, thanking the goodwill, or judging the compromise advantageous. The case illustrates the technique in its solo form, a single actor taking on both roles in turn.
Political · The Iranian nuclear file: Europe as good cop, the United States as bad cop, In the negotiations over the Iranian nuclear programme in the mid-2000s, the European trio (EU-3) played the good cop by offering trade incentives and agreements, while the United States embodied the bad cop by brandishing the threat of sanctions and referral to the Security Council. As the diplomatic literature analyses it, this division stemmed as much from genuine political differences as from deliberate orchestration. The contrast between the European carrot and the American stick structured the pressure on Tehran, illustrating the technique on the scale of international relations.
Diplomatic · Threat at the top, an outstretched hand at the operational level, In several contemporary diplomatic sequences, a head of state multiplies coercive declarations and tariff threats while their diplomats discreetly propose agreements. This division of roles, displayed hardness at the top, conciliation at the technical level, exactly reproduces the good cop, bad cop logic. Analysis of foreign affairs stresses that the counterpart, caught between public threat and private opening, tends to seize the exit offered by the diplomat to avoid escalation, even though both messages come from the same camp.
Judicial · Police interrogation, the historical matrix of the technique, The technique takes its name from the interrogation rooms where an aggressive investigator, accusations, threats of a heavy sentence, precedes a calm one offering coffee, a listening ear and a "reasonable way out". Rafaeli and Sutton, studying criminal interrogators, formalised this emotional contrast as a lever for confession. Research and case law have since highlighted the risks: the relief provided by the good cop can lead to unreliable confessions, which has fuelled debates on the regulation of interrogation methods and the reliability of confessions obtained under pressure.
Business · The buyer duo: uncompromising director, conciliatory operational buyer, In many procurement departments, supplier negotiation is structured as a duo: a procurement director sets shock demands (an aggressive cut, penalties, re-tendering), then an operational buyer takes the supplier aside to "find a solution". The experimental work of Brodt and Tuchinsky (2000) confirms the effectiveness of this sequence when the hard cop opens and the conciliatory one follows: the supplier, relieved, concedes margins it was defending, while preserving a working relationship with the operational buyer.
Everyday life · Buying a car: the salesperson and "the boss", A classic scene at the car dealership: the salesperson insists they can give nothing more, then goes to "see the manager" and returns with a gesture presented as exceptional and personal. The customer, who feared going home empty-handed, experiences the discount as a victory wrested thanks to an inside ally. This everyday script, widely described in the sales literature, mobilises contrast and reciprocity: relief and gratitude push the customer to sign without checking whether the offer is genuinely advantageous.
