The more quickly people reach an understanding of negative events, the sooner they recover from them. […] Virtually all tests […], however, have examined people’s understanding of negative events. The AREA [attend, react, explain, and adapt] model is unique in predicting that explanation also leads to the diminution of affective reactions to positive events. We predict that anything that impedes explanation—such as uncertainty—should prolong affective reactions to positive events. […] These studies highlight a pleasure paradox, which refers to the fact that people have two fundamental motives—to understand the world and to maintain positive emotion—that are sometimes at odds.

There are many different techniques for collecting, interpreting, and analyzing facts, and different techniques often lead to different conclusions, which is why scientists disagree about the dangers of global warming, the benefits of supply-side economics, and the wisdom of low-carbohydrate diets. Good scientists deal with this complication by choosing the techniques they consider most appropriate and then accepting the conclusions that these techniques produce, regardless of what those conclusions might be. But bad scientists take advantage of this complication by choosing techniques that are especially likely to produce the conclusions they favour, thus allowing them to reach favoured conclusions by way of supportive facts. Decades of research suggests that when it comes to collecting and analyzing facts about ourselves and our experiences, most of us have the equivalent of an advanced degree in Really Bad Science.

Nozick’s “happiness machine” problem is a popular among academics, who generally fail to consider three things. First, who says that no one would want to be hooked up? The world is full of people who want happiness and don’t care one bit about whether it is “well deserved.” Second, those who claim that they would not agree to be hooked up may already be hooked up. After all, the deal is that you forget your previous decision. Third, no one can really answer this question because it requires them to imagine a future state in which they do not know the very thing they are currently contemplating.
