Sir Arthur Eddington, an English astrophysicist, told a short story involving a scientist studying fish found with nets.
He studied the characteristics of the fish that were landed and he concluded that there is a minimum size of fish in the sea. In other words, given the sample he studied, there were no fish to be found smaller than a certain size.
However, as you soon realize, the fish seen were determined by the size of the holes in the net. The smaller ones slipped through, uncaptured and therefore unmeasurable.
The instrument you use affects what you see and the map you create of that landscape, on the sea or in your business.
Or, as Bill Ringle says: “The results you get are predicted by what you measure.”
