Probability is not enough

"The danger is that by extending probability to everything, it is easy to be seduced into thinking that one tool—calculating probabilities—is sufficient for dealing with all kinds of uncertainty. As a consequence, other important tools, such as rules of thumb, are left in the cupboard." (from "Risk Savvy: How To Make Good Decisions" by Gerd Gigerenzer)

"The important point is that ignoring information can lead to better, faster, and safer decisions. The gaze heuristic is successful because of our evolved brains. That’s why pilots, outfielders, or dogs can rely on it, while it is of limited use for robots and computers." (from "Risk Savvy: How To Make Good Decisions" by Gerd Gigerenzer)
