This Word of Mouth episode about the language of cults introduced me to the idea of the Thought Terminating Cliche: a bit of language used to stop further discussion or questioning. It was first used to describe language structures of the Chinese Communist Party. In everyday life it's things like: 'it is what it is' or 'I'm just saying' or 'that's just your opinion'.
It struck me that corporate life is full of these things too. Injunctions to, basically, please stop asking questions and just get on with stuff. 'Carpe diem'. 'JFDI'.
And in some senses, and in regular life too, a thought-terminating cliche might have some utility. Sometimes the thinking has to stop. Sometimes we need something to gee us out of our analysis paralysis.
