Example: 2003, J. A. Keats, Norman Cliff, Ordinal Measurement in the Behavioral Sciences (page 31) 
"It seems to be saying one or both of two things. One is that any score that comes out of any procedure that purports to measure intelligence is a value of the scale, intelligence. If so, this would be Humpty Dumptyism."
