Precommitment

For the concept in cryptography, see commitment scheme.

For the campaign to reduce self-harm by gamblers, see Andrew Wilkie.

Precommitment is a strategy in which a party to a conflict uses a commitment device to strengthen its position by cutting off some of its options to make its threats more credible. Any party employing a Strategy of Deterrence faces the problem that retaliating against an attack may ultimately result in significant damage to their own side. If this damage is significant enough, then the opponent may take the view that such retaliation would be irrational, and therefore, that the threat lacks credibility, and hence, it ceases to be an effective deterrent. Precommitment improves the credibility of a threat, either by imposing significant penalties on the threatening party for not following through, or, by making it impossible to not respond.
