9. Gretchen Rubin

During her multibook investigation into human nature, Gretchen Rubin realized that by asking the seemingly dry question “How do I respond to expectations?” we gain explosive self-knowledge. She discovered that based on their answer, people fit into Four Tendencies:

• Upholders meet outer and inner expectations readily. “Discipline is my freedom.”
• Questioners meet inner expectations, but meet outer expectations only if they make sense. “If you convince me why, I’ll comply.”
• Obligers (the largest Tendency) meet outer expectations, but struggle to meet inner expectations—therefore, they need outer accountability to meet inner expectations. “You can count on me, and I’m counting on you to count on me.”
• Rebels (the smallest group) resist all expectations, outer and inner alike. They do what they choose to do, when they choose to do it, and typically they don’t tell themselves what to do. “You can’t make me, and neither can I.”

Our Tendency shapes every aspect of our behavior, so using this framework allows us to make better decisions, meet deadlines, suffer less stress, and engage more effectively. It’s far easier to succeed when you know what works for you.

With sharp insight, compelling research, and hilarious examples, The Four Tendencies will help you get happier, healthier, more productive, and more creative.
