“We’re face-to-face with our old foe: the combinatorial explosion. Therefore we do what we always have to do in life: compromise. We make simplifying assumptions that whittle the number of probabilities we have to estimate down to something manageable. A very simple and popular assumption is that all the effects are independent given the cause. This means that, for example, having a fever doesn’t change how likely you are to also have a cough, if we already know you have the flu. Mathematically, this is saying that P(fever, cough | flu) is just P(fever | flu) × P(cough | flu). Lo and behold: each of these is easy to estimate from a small number of observations. In fact, we did it for fever in the previous section, and it would be no different for cough or any other symptom. The number of observations we need no longer goes up exponentially with the number of symptoms; in fact, it doesn’t go up at all.”

“There’s something else about this list that really jumps out. Take another look at the top five attributes listed there—the key characteristics defining a world-class sales experience: Rep offers unique and valuable perspectives on the market. Rep helps me navigate alternatives. Rep provides ongoing advice or consultation. Rep helps me avoid potential land mines. Rep educates me on new issues and outcomes. Each of these attributes speaks directly to an urgent need of the customer not to buy something, but to learn something. They’re looking to suppliers to help them identify new opportunities to cut costs, increase revenue, penetrate new markets, and mitigate risk in ways they themselves have not yet recognized. Essentially this is the customer—or 5,000 of them at least, all over the world—saying rather emphatically, “Stop wasting my time. Challenge me. Teach me something new.”

“Your job in a world of intelligent machines is to keep making sure they do what you want, both at the input (setting the goals) and at the output (checking that you got what you asked for).”
