=== Reducing choice overload === Classical economics predicts that providing more options will generally improve consumer utility, or at least leave it unchanged. However, each additional choice demands additional time and consideration to evaluate, potentially outweighing the benefits of greater choice. Behavioral economists have shown that in some instances presenting consumers with many choices can lead to reduced motivation to make a choice and decreased satisfaction with choices once they are made. This phenomenon is often referred to as choice overload, overchoice or the tyranny of choice. However, the importance of this effect appears to vary significantly across situations. Choice architects can reduce choice overload by either limiting alternatives or providing decision support tools. Choice architects may choose to limit choice options; however, limits to choice may lead to reductions of consumer welfare. This is because, the greater the number of choices, the greater the likelihood that the choice set will include the optimal choice for any given consumer. As a result, the ideal number of alternatives will depend upon the cognitive effort required to evaluate each option and the heterogeneity of needs and preferences across consumers. There are examples of consumers faring worse with many options rather than fewer in social-security investments and Medicare drug plans As consumption decisions increasingly move online, consumers are relying upon search engines and product recommendation systems to find and evaluate products and services. These types of search and decision aids both reduce the time and effort associated with information search, but also have the power to subtly shape decisions dependent upon what products are presented, the context of the presentation, and the way that they are ranked and ordered. For example, research on consumer goods like wine has shown that the expansion of online retailing has made it simpler for consumers to gather information on products and compare alternatives, making them more responsive to price and quality information.
=== Defaults === A large body of research has shown that, all things being equal, consumers are more likely to choose default options. A default is defined as a choice frame in which one selection is pre-selected so that individuals must take active steps to select another option. Defaults can take many forms ranging from the automatic enrollment of college students in university health insurance plans to forms which default to a specific option unless changed. Several mechanisms have been proposed to explain the influence of defaults. For example, individuals may interpret defaults as policymaker recommendations, cognitive biases related to loss aversion like the status quo bias or endowment effect might be at work, or consumers may fail to opt-out of the default due to associated effort. It is important to note that these mechanisms are not mutually exclusive and their relative influence will likely differ across decision contexts. Types of default include simple defaults where one choice is automatically selected for all consumers, forced-choice in which a product or service is denied until the consumer makes a proactive selection, and sensory defaults in which the choice is pre-selected based upon other information that was gathered about specific consumers. Choices that are made repeatedly may also be affected by defaults, for instance, persistent defaults may be continually reset regardless of past decisions, whereas reoccurring defaults "remember" past decisions for use as the default, and predictive defaults use algorithms to set defaults based upon other related behavior. One of the most commonly cited studies on the power of defaults is the example of organ donation. One study found that donor registration rates were twice as high when potential donors had to opt out versus opt into donor registration. However, the influence of defaults has been demonstrated across a range of domains including investment and insurance
=== Choice over time === Choices with outcomes that manifest in the future will be influenced by several biases. For example, individuals tend to be myopic, preferring positive outcomes in the present often at the expense of future outcomes. This may lead to behaviors like overeating or overspending in the short-term at the expense of longer-term health and financial security outcomes. In addition, individual projections about the future tend to be inaccurate. When the future is uncertain they may overestimate the likelihood of salient or desirable outcomes, and are generally overly optimistic about the future, for example assuming that they will have more time and money in the future than they will in actuality. However research indicates that there are several ways to structure choice architecture to compensate for or reduce these biases. For example, researchers demonstrated improved decision-making by drawing attention to the future outcomes of decisions or by emphasizing second best options. In addition, limited time offers can be successful in reducing procrastination.
=== Partitioning options and attributes === The ways in which options and attributes are grouped influence the choices that are made. Examples of such partitioning of options include the division of a household budget into categories (e.g. rent, food, utilities, transportation etc.), or categories of investments within a portfolio (e.g. real estate, stocks, bonds, etc.), while examples of partitioning attributes include the manner in which attributes are grouped together for example a label may group several related attributes together (e.g. convenient) or list them individually (e.g. short running time, little cleanup, low maintenance). The number and type of these categories is important because individuals have a tendency to allocate scarce resources equally across them. People tend to divide investments over the options listed in 401K plans they favor equal allocation of resources and costs across individuals (all else being equal), and are biased to assign equal probabilities to all events that could occur. As a result, aggregate consumption can be changed by the number and types of categorizations. For instance, car buyers can be nudged toward more responsible purchases by itemizing practical attributes (gas mileage, safety, warranty etc.) and aggregating less practical attributes (i.e. speed, radio, and design are grouped together as "stylishness").
