nudge
NUJ
/nʌdʒ/
A subtle policy or design intervention that predictably alters human behavior without forbidding choices or altering economic incentives.
Implies a gentle push that preserves freedom of choice rather than forced mandates or explicit financial punishments.
The story behind the word. Entering English in the 17th century as a physical term for prodding someone gently with an elbow to get their attention, 'nudge' gained global academic prominence when Nobel laureate Richard Thaler and legal scholar Cass Sunstein published their 2008 book titled 'Nudge'.
