The big idea: the simple trick that can sabotage your critical thinking

Influencers and politicians use snappy cliches to get you on side - but you can fight fire with fire

Since the moment I learned about the concept of the thought-terminating cliche" I've been seeing them everywhere I look: in televised political debates, in flouncily stencilled motivational posters, in the hashtag wisdom that clogs my social media feeds. Coined in 1961 by psychiatrist Robert Jay Lifton, the phrase describes a catchy platitude aimed at shutting down or bypassing independent thinking andquestioning. I first heard about the tactic while researching a book about the language of cult leaders, but these sayings also pervade our everyday conversations: expressions such as It is what it is", Boys will be boys", Everything happens for a reason" and Don't overthink it" are familiar examples.

From populist politicians to holistic wellness influencers, anyone interested in power is able to weaponise thought-terminating cliches to dismiss followers' dissent or rationalise flawed arguments. In his book Thought Reform and the Psychology of Totalism, Lifton wrote that these semantic stop signs compress the most far-reaching and complex of human problems ... into brief, highly selective, definitive-sounding phrases, easily memorized and easily expressed. They become the start and finish of any ideological analysis."
