Sludge
Fleetingsludge
Sludge is a relatively recent addition to the so-called nudge theory, characterized by Cass Sunstein as “frictions that make good decisions harder”. When Richard Thaler introduced the term to the lexicon with the comment “less sludge will make the world a better place” by coupling friction with bad intent as the key criteria of sludge. They have also been described by Dilip Soman as “frictions in any process that impedes end users, and ultimately reduces welfare”.
