[from Latin musculus + Latin memoria: muscle + memory] “We aren’t going to surrender any of the expense discipline we have worked into the muscle memory of our firm,” Citigroup Inc. CEO Michael Corbat, Bloomberg, July 25, 2017
Muscle memory is no stretch
What do muscles have to do with business procedures? Also called motor memory, muscle memory is the ability to automatically perform a movement learned through frequent repetition. Muscle memory isn’t stored in muscles but in the brain: it’s a type of procedural memory, which involves knowing how to do something without consciously thinking about it thanks to repeated practice. That memory needn’t even involve much muscular effort–for example, reading, driving a car or typing a password. Procedural or muscle memory is long lasting and habitual, which is why we don’t forget how to ride a bicycle–or to exercise expense discipline.
