Something that encourages specific behavior

Some core ideas in behavioral economics focus on people's propensity to do nothing, as evident in default bias and status quo bias. Inaction may be due to a number of factors, including inertia or anticipated regret. However, sometimes people have an impulse to act in order to gain a sense of control over a situation and eliminate a problem. This has been termed the action bias (Patt & Zeckhauser, 2000). For example, a person may opt for a medical treatment rather than a no-treatment alternative, even though clinical trials have not supported the treatment's effectiveness.
