“In accident investigation, as in most other human endeavours, we fall prey to the What-You-Look-For-Is-What-You-Find or WYLFIWYF principle. This is a simple recognition of the fact that assumptions about what we are going to see (What-You-Look-For), to a large extent will determine what we actually find (What-You-Find). (The principle is furthermore not limited to accident investigation, but applies to human perception and cognition in general.) In accident investigations, the guiding assumptions are sometimes explicit, for instance when they are given as a directive or objective.

“All work is knowledge work. The carpenter’s mind is no less animated and engaged than the actuary’s. The architect’s accomplishments depend as much on the body and its senses as the hunter’s do.”

“If professionals consider one thing “unjust,” it is often this: Split-second operational decisions that get evaluated, turned over, examined, picked apart, and analyzed for months—by people who were not there when the decision was taken, and whose daily work does not even involve such decisions.”
