לא רציונלי ולא במקרה - בסדרה של ניסויים סותר הכלכלן ההתנהגותי דן אריאלי את הסברה הרציונלית שלפיה התנהגות בני האדם רציונלית מיסודה.
בעזרת סיפורים מחיי היום יום ומחקרים פורצי דרך מסביר אריאלי איך יכולת השיפוט שלנו מוטה על ידי ציפיות, רגשות, נורמות חברתיות וכוחות נוספים, בלתי נראים ובלתי רציונליים. אריאלי מראה שלא רק שאנחנו עושים טעויות מדהימות בפשטותן מדי יום, אלא שאנחנו גם חוזרים על אותו סוג של טעויות שוב ושוב. באופן שיטתי אנחנו משלמים יותר מדי, טועים בהערכותינו ודוחים דברים שעלינו לעשות. אנחנו מזלזלים בהשפעת הרגש על קבלת ההחלטות שלנו ומפריזים בהערכת ערכו של רכושנו. אולם ההתנהגויות השגויות הללו אינן אקראיות. לא רציונלי ולא במקרה ישנה לתמיד את האופן שבו אתם מתַקשרים עם העולם ואת דרך קבלת ההחלטות שלכם.
