Social support refers to the perception or reality that other people will provide assistance in a given context. It is a key component of several behavior models and plays an important role in mediating behavior change. ‍

Reminders, cues, and prompts are simply methods to cause someone to perform a behavior by calling their attention to it with a timely message. People have limited attention and memory, so these types of influences can be very effective when done skillfully. The cue need not consist of written or spoken language; for example, it could be a certain melody, symbol, or pattern of lights on a connected home device. It might also be a bracelet or pattern of vibrations from a wearable device. Provided the cue or prompt is associated with the behavior, almost any sensory stimuli that is reliably perceived and interpreted may be used. That said, verbal reminders can be effective since they may be personalized with additional semantic information related to the person's context or leverage other effects (e.g. identity priming or framing effects).

Implementation intentions are specific details for when and how a behavior should or will be performed. These are often formulated as ""if-then"" rules, such as:- "if I crave something sweet, I'll have fruit instead of candy"- "if I am in the mood for a cigarette, I'll wait 5 minutes—then, if I still want it, I can have one"Other examples include studies where flu vaccination uptake was higher in groups of people nudged to make more specific plans (i.e. picking a specific time and date, along with a mode of transport to a specific clinic). The same general effect was observed with voting behaviors. These are a generally low-cost tool to slightly improve the gap between intention and performance of a behavior.

Environmental restructuring refers to modifying the physical environment around someone in order to influence their behavior.On the less intensive end, this could be as simple as having someone leave a pill bottle in a more obvious location or switch to using a pillbox with compartments for each day. More complex examples include carpooling potential voters to election sites to improve turnout, redesigning a workplace cafeteria layout to bias toward healthier foods, or setting up booths for influenze vaccination in offices or shopping malls.

Education refers to empowering a person with more knowledge or training than they had previously. While providing information alone is often a suboptimal way to drive meaningful behavior change or long-term interventions, the right message at the right time can be a powerful part of a behavior change strategy.‍

Reducing friction or barriers to performing a behavior is simply making it easier or removing things that may be preventing someone from doing something. This is a foundational technique in changing behavior, and part of the UK Behavioural Insights Team's 4-point approach ("Make it easy"). That said, knowing where the friction and barriers exist may not always be straightforward, and different groups of people may experience different barriers in different contexts. Note: It is possible to remove too much friction. In a well-popularized study, a travel booking site found that delays in loading the best deals or travel options actually increased conversions. Similarly, longer input forms in digital interactions sometimes outperform, as people may consider the results more personalized or experience greater cognitive dissonance after having invested so much time in exploring the service.
