Content: This article is not a reproduction or extraction of Thaler and Sunstein's work - it is a summary, interpretation and extension of 'Nudge' theory, including the main terminology, expanded by supplementary methods, with helpful explanations, examples  and connections, to related ideas and concepts of motivation and management. Accordingly, if you seek to understand Thaler and Sunstein's work first-hand, or to research and extract from the original Thaler-Sunstein source material, then you should obtain their book 'Nudge', and also explore Kahneman and Tversky's earlier  work. If you extract/quote from this article please clarify in the citation that the extract is taken from this article/webpage, (which is, therefore, a 'secondary source' in terms of the theories of Thaler, Sunstein, Kahneman and Tversky). Like  any review this article is open to debate as to how precisely it interprets and represents the original (Thaler-Sunstein/Kahneman-Tversky) work, and this is especially so because of the adaptive and developmental nature of this article. Introduction
Nudge theory is credited mainly to American academics Richard H Thaler and Cass R Sunstein. They built much of their theory on the ' heuristics ' work  of Israeli-American psychologists Daniel Kahneman and Amos Tversky, which first emerged in the 1970s in psychological journals. The name and concept of 'Nudge' or 'Nudge theory' were popularized by the 2008 book, ' Nudge: Improving Decisions About Health, Wealth, and Happiness ',  which became a major international best-seller. Kahneman's 2012 book, also a best-seller, ' Thinking, Fast and Slow ' contains much of the fundamental Khaneman-Tversky theory which underpins the Thaler-Sunstein 'Nudge' concept. Amos Tversky  is somewhat neglected in citations for Nudge theory because he died in 1996.
