“suspension of disbelief.”
I’ve always hated that term. It’s like George Carlin used to say...using unneccesary wordiness when one simple one will do is an attempt to raise the stature of a speaker and temporarily confuse the listener.
Ie. Q”How are you doing today”? A: “I’m not unwell”.
There’s nothing unnecessarily wordy about “suspension of disbelief.” It’s shorter than “turn your brain off and stop thinking critically.”
