The way options are presented — defaults, ordering, framing — systematically influences what people choose, even when no option is removed. Because there is no neutral way to present choices, whoever designs the environment is always a 'choice architect' steering behavior, so the only real question is whether to do it deliberately and helpfully.
A nudge alters behavior predictably without forbidding options or significantly changing economic incentives, such as placing fruit at eye level rather than banning junk food. This 'libertarian paternalism' lets institutions guide people toward better outcomes while keeping every choice cheap to opt out of.
Reading a popular work like Star Wars as a series of authorial and audience choices reveals how meaning is constructed retroactively and contested over time, mirroring how legal texts are interpreted. Treating fiction as a case study exposes the same dynamics — original intent versus evolving meaning — that govern reading any foundational document.
