Widespread incentive-caused bias requires that one should often distrust or take with a grain of salt the advice of one’s professional adviser, even if he is an engineer. The general antidotes here are: 1) Especially fear professional advice when it is especially good for the adviser, 2) learn and use the basic elements of your adviser’s trade as you deal with your adviser, and 3) double-check, disbelieve, or replace much of what you’re told, to the degree that seems appropriate after objective thought.
