"Intelligent" test interpretation - We are the instrument

A quote that has often  been attributed to me, based on some comments I made on a Listserv many years ago and on a  slide I often use when presenting at workshops is...."we are the instrument"...with re: to the art and science of "intelligent" intelligence testing and interpretation by psychologists. It reminded me of a quote that captures a good portion of the variance of my "we are the instrument" mantra. It is reproduced below. The source is also listed.
