• Why do our headaches persist after taking a one-cent aspirin but disappear when we take a 50-cent aspirin?
• Why does recalling the Ten Commandments reduce our tendency to lie, even when we couldn't possibly be caught?
• Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?
• Why do we go back for second helpings at the unlimited buffet, even when our stomachs are already full?
• And how did we ever start spending $4.15 on a cup of coffee when, just a few years ago, we used to pay less than a dollar?

When it comes to making decisions in our lives, we think we're in control. We think we're making smart, rational choices. But are we?

In a series of illuminating, often surprising experiments, MIT behavioral economist Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. Blending everyday experience with groundbreaking research, Ariely explains how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities.

Not only do we make astonishingly simple mistakes every day, but we make the same types of mistakes, Ariely discovers. We consistently overpay, underestimate, and procrastinate. We fail to understand the profound effects of our emotions on what we want, and we overvalue what we already own. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable—making us predictably irrational.

From drinking coffee to losing weight, from buying a car to choosing a romantic partner, Ariely explains how to break through these systematic patterns of thought to make better decisions. Predictably Irrational will change the way we interact with the world—one small decision at a time.

On September 6, 2007, an African Grey parrot named Alex died prematurely at age thirty-one. His last words to his owner, Irene Pepperberg, were "You be good. I love you."

What would normally be a quiet, very private event was, in Alex's case, headline news. Over the thirty years they had worked together, Alex and Irene had become famous—two pioneers who opened an unprecedented window into the hidden yet vast world of animal minds. Alex's brain was the size of a shelled walnut, and when Irene and Alex first met, birds were not believed to possess any potential for language, consciousness, or anything remotely comparable to human intelligence. Yet, over the years, Alex proved many things. He could add. He could sound out words. He understood concepts like bigger, smaller, more, fewer, and none. He was capable of thought and intention. Together, Alex and Irene uncovered a startling reality: We live in a world populated by thinking, conscious creatures.

The fame that resulted was extraordinary. Yet there was a side to their relationship that never made the papers. They were emotionally connected to one another. They shared a deep bond far beyond science. Alex missed Irene when she was away. He was jealous when she paid attention to other parrots, or even people. He liked to show her who was boss. He loved to dance. He sometimes became bored by the repetition of his tests, and played jokes on her. Sometimes they sniped at each other. Yet nearly every day, they each said, "I love you."

Alex and Irene stayed together through thick and thin—despite sneers from experts, extraordinary financial sacrifices, and a nomadic existence from one univer­sity to another. The story of their thirty-year adventure is equally a landmark of scientific achievement and of an unforgettable human-animal bond.
