Tactics that change behavior

Personalization
Personalization

Personalization refers to taking specific data from the individual in a behavioral intervention into account in offering a different experience vs. that given to others.

An experience may be personalized based on demographic data, psychographic data, behavioral performance, or other factors.

Checklists
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.

Identity Priming
Identity Priming

Identity priming refers to attempting to influence someone's behavior by emphasizing their being part of to a certain group or being a certain type of person. These often leverage social norms—particularly injunctive norms—and introjected regulation.

For example, voter turnout campaigns often emphasize the person's membership to the community or previous voting history in reminder letters.

Rules of Thumb
Rules of Thumb

Rules of thumb refer to simplifation heuristics used in dealing with uncertainty, situations where tracking behaviors can be onerous, or areas where one-size-fits-all approaches may not be successful. They can be a useful tool to reduce the cognitive load of complying with a new behavior.

For example, a person may find it easier to "eat out at restaurants only 4 times per month" rather than "limit monthly restaurant spending to $200." Similarly, avoiding eating certain types of foods, e.g. fried foods or high-calorie drinks, may be easier to recall and comply with than hitting a daily calorie goal.

Personalization

Personalization refers to taking specific data from the individual in a behavioral intervention into account in offering a different experience vs. that given to others.

An experience may be personalized based on demographic data, psychographic data, behavioral performance, or other factors.

Social Benchmarking
Social Benchmarking

Social benchmarking refers to comparing a person's behavior, trends, or status to others. Often, merely providing data on others can change behavior by leveraging social norms.

For example, letters comparing homeowners' use of electricity with peers were found to significantly reduce the amount of energy used by high-consumption households compared to non-comparison messages.

Cognitive Behavioral Therapy (CBT)
Cognitive Behavioral Therapy (CBT)

Cognitive behavioral therapy (CBT) is a therapuetic approach to improving mental and behavioral health. The core philosophy is that behavior can be modified by noticing and correcting patterns in thought that influence the behavior. Modern CBT is typically associated with Albert Ellis and Alan Beck.

The structured and rules-based nature of CBT have made it a popular candidate for digital interventions and application by lightly-trained or even untrained practitioners.

Tracking behavior
Tracking behavior

Self-monitoring or tracking simply refers to a person measuring their behavior over time.

Often, merely tracking a behavior can influence the likelihood or frequency with which a person performs the behavior or related ones. For example, many pedometer studies increase walking activity merely by improving awareness, and many interventions that merely consist of rewarding someone for weighing themselves result in weight loss.

That said, people often find tracking behaviors tedious and lose interest after a short period, so behavior designers should seek to reduce the burden of self-monitoring by collecting information automatically or doing so in a low-cost way.
