This term coined by Thaler and Sunstein (2008) refers to the practice of influencing choice by “organizing the context in which people make decisions” (Thaler et al., 2013, p. 428; see also nudge). A frequently mentioned example is how food is displayed in cafeterias, where offering healthy food at the beginning of the line or at eye level can contribute to healthier choices. Choice architecture includes many other behavioral tools that affect decisions, such as defaults, framing, or decoy options.
