“Much of economics theory is based on the premise that people are rational decision-makers. In recent years, behavioral economics—also known as behavioral finance—has emerged as a discipline, bringing together economics and psychology to understand how social, cognitive, and emotional factors influence how people make decisions, both as individuals and at the market level. Many of the findings of behavioral economics have a direct influence on how users interact with a product. In a worst‑case scenario, a product’s design may encourage user behaviors that are detrimental to users’ best interests.” (Peter Hornsby ~ UXmatters)
