An implementation intention is a self-regulatory strategy introduced by psychologist Peter Gollwitzer in 1999 to improve goal attainment through specific if-then plans. Unlike broad goal intentions ("I want to reach X"), these plans specify the when, where, and how by connecting a future cue to a concrete behavior, such as "When situation X arises, I will perform response Y." This technique was developed because research revealed that strong intentions account for only 20-30% of behavior variance, as people often struggle to act on their good intentions. By consciously linking a situation to a response, it creates new habits and automates goal-directed behavior, helping to modify problematic actions and sustain effort toward personal, relational, or health-related goals. Ultimately, this method predetermines a desired response to a future event, significantly increasing the probability of successfully achieving one's objectives and improving life in one or several aspects.
