Can our healthy selves predict how we will feel in unhealthy circumstances with enough certainty to choose whether we would want to live or die? Can our present selves, in general, make reliable choices for our futures selves? How good are our decisions anyway, and how do we make them?

The "focusing illusion," according to Mr. Kahneman, happens when we call up a specific attribute of a thing or experience (e.g., climate) and use it to answer a broader and more difficult question (what makes life enjoyable, in California or anywhere else?).

One major effect of the work of Messrs. Kahneman and Tversky has been to overturn the assumption that human beings are rational decision-makers who weigh all the relevant factors logically before making choices. When the two men began their research, it was understood that, as a finite device with finite time, the brain had trouble calculating the costs and benefits of every possible course of action and that, separately, it was not very good at applying rules of logical inference to abstract situations. What Messrs. Kahneman and Tversky showed went far beyond this, however. They argued that, even when we have all the information that we need to arrive at a correct decision, and even when the logic is simple, we often get it drastically wrong.
