Lotteries
Lotteries are any form of assigning an award where there is an element of randomness or chance.One example is a prize-linked savings account (PLSAs). One of the earliest of these was the Million a Month Account (MAMA) in South Africa, where First National Bank offered account-holders with qualifying deposits a chance to win up to one million rand each month (along with other smaller prizes given out at random). Lotteries may be used with non-financial rewards as well, e.g. offering tickets to a sold-out play or sporting event for employees reaching certain performance benchmarks.

TACTICS
Acceptance and Commitment Therapy (ACT)
ACT is a therapeutic approach originalled developed by Steven Hayes. It borrows from previous concepts like cognitive behavioral therapy and Morita therapy. The principles of ACT are fairly systematic and lend themselves well to program design, finding empirical support in adaptations like 2morrow's smoking cessation and pain management interventions.

TACTICS
Active Choice
Active choice, sometimes referred to as enhanced active choice or forced choice, refers to removing default options and often increasing the salience of potential decisions through emphasizing the consequences of one or more of the options. Coined by Punam Anand Keller and colleagues in 2011, it was originally intended to address concerns around paternalistic nudging for use in situations where forcing the default option may be considered unethical. In one of the original studies, CVS customers were given the choice to enroll in automatic refills of medications via delivery. The choices they were presented were ""Enroll in refills at home"" vs “I Prefer to Order my Own Refills.”

TACTICS
Automation
Automation refers to having another person, group, or technology system perform part or all of the intended behavior. A prominent example is Thaler & Bernartzi's Save More Tomorrow intervention, which invested a portion of employees' earnings into retirement funds automatically and even increased the contribution level to scale with pay raises. Other examples include automatically scheduling medical appointments so the patient needn't do it themselves and mailing healthy recipe ingredients to the person's home to reduce the burden of shopping.

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
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.
