Tactics that change behavior

TACTICS
Behavior Substitution
Behavior substitution refers to attempting to eliminate a problematic behavior by replacing it with another one. Often, the substituted behaviors are intended to have similar sensory qualities (e.g. drink flavored sparkling water instead of soda). The goal is typically to disassociate the original behavior from its cue, enabling the more positive behavior to be triggered automatically.

TACTICS
Coaching or Counselling
Coaching or counselling here refers to having a trained person provide guidance to someone attempting a behavior. Many mental health and lifestyle programs utilize coaching in various forms, including phone calls, video chat, text messaging, or in-person sessions. Some programs have replaced some or all of these traditionally human-delivered touchpoints with AI or rules-based interactions.

TACTICS
Behavioral Activation (BA)
Behavioral activation is a therapeutic approach that typically pairs activity scheduling with either monitoring tools or goal-setting. For example, someone might aim to balance activities they "should" do but underperform, like self-care behaviors, with activities they enjoy. Users of this technique may also track which activities cause certain cognitions or affective states, like those associated with depression.

TACTICS
Change Effort
Changing effort refers to modifying the difficulty, or sometimes perceived difficulty, of a behavior in order to change its likelihood of occurrence. This often entails making a behavior easier by reducing its intensity or frequency. This is a tactic advocated by BJ Fogg’s model of behavior change.

TACTICS
Behavioral Economics
Behavioral economics is the exploration of how people make consequential decisions where psychological and sociological factors may influence the outcome or process. It is often considered the fusion of economics and psychology (which itself was an interdisciplinary field entailing medicine and philosophy). The exploration of psychological factors in economic decision-making, including deviation from rationality, traces well back to classical and neoclassical economics (i.e. Gabriel Tarde, Wilfredo Pareto, and John Maynard Keynes) and prior to psychology becoming a formal discipline. Behavioral economics is often associated with behavior change tactics like smart defaults, reducing friction or barriers, increasing salience, incentives, active choice, and commitment devices.

TACTICS
Checklists
Checklists are an age-old tactic for remembering to do certain tasks. Checklists are sometimes used to measure behaviors that should take place with a certain frequency, e.g. every day or X times per week, and other times, to ensure certain steps are followed every time a person does a complex behavior.For behavior designers, the challenges of checklists often entail choosing the right behaviors, breaking them down to the correct level of granularity for a given population, and serving them up in the proper context or sometimes with personalization. They are likely underutilized and consistently improve the performance of even experts, like pilots and surgeons.

TACTICS
AI or Chatbot
Using a chatbot or simulated conversational interaction.

TACTICS
Depression rating
Depression rating simply refers to having someone rate their mood. Often, this may be an informal method like a smiley-face based Lickert scale or choosing a word from a list, rather than using a standardized instrument like the Beck Depression Inventory.
