Nigel from NLP Demystified wrote a few days ago about calibration. He said:
So one explanation of calibration is the detection of some repetitive pattern in some context. [...] This is a simple definition, as it should be. What is noticed repetitively and is then verified is the result of calibration; noticing repetitive patterns of behaviour/actions etc.
That’s a very useful and succinct definition of calibration. In the context of NLP, I’d add that calibration consists of associating a verifiable, external behavioral pattern (such as winking, wriggling the nose or breathing in a certain pattern) to an internal state or thought pattern.
Based on that definition, you calibrate the internal state based on the external behavior or response.
