Is nudge necessarily benevolent?

Cʹis a nudge, nothing more. A gentle incentive to act in the best way for ourselves and others in public or private space. From signposts and road markings to the must-have gel dispensers at store entrances: nudges have been multiplied since the start of the pandemic. For our own good, always. But to what extent and until when? Because there is a fine line between nudge and sludge, cʹest-à dire entre le coup de coude sans contrainte et la manipulation.
