Not enough people taste as they go.
While making a soup, tasting it 7 times and tweaking exposes you to up to 7 different variations of the dish. When you cook the soup the next time, you can draw upon this knowledge. To develop the same understanding without sampling requires you to cook the entire dish 7 times while varying the dish each time.
Several professionals use sampling – product designers who perform A-B testing, musicians who tweak their instrument’s tone between songs and mechanics who test drive the automobiles that they have tinkered with.
Sampling requires you to leave the safety of a recipe or a user manual behind. But in the bargain, it turns you from a cook into a chef.
