|Observation requires training|
After Watson and I had examined together the apartment of Dr. Grimesby Roylott, we had the following conversation:
You have evidently seen more in those rooms than was visible to me. No but I fancy that I may have deduced a little more, I imagine that you saw all that I did [SPEC].The difference between Watson and me is that I have trained myself to observe. In answer to the incredulous comments of clients about some little demonstration of the science of observation, I have said
I have trained myself to see what others overlook [IDEN].
I see no more than you but I have trained myself to notice what I see [BLAN].
Such demonstrations are impressive only because, with considerable training, observation with me is second nature [STUD].
