Key ideas from Nir Eyal

• Beliefs literally shape what you see - the same image can appear as circles or rectangles depending on your background and priors
• Placebos work even when you know they're placebos, with Harvard studies showing placebo pills labeled as such performing as well as leading IBS medications
• Motivation is a triangle requiring behavior, benefit, and belief - without belief in yourself or the outcome, motivation collapses
• We process only 50 bits of 11 million bits of information per second, meaning we see reality based on predictions, not actual input
• Successful people fail more than unsuccessful people - persistence is the defining factor, with rats swimming 240 times longer when they believed salvation was possible
• Prayer provides measurable health benefits even without faith - people who pray live longer, are healthier, and have lower rates of depression and anxiety
• Pain is always real but exists in the brain as information, not necessarily indicating damage - chronic pain often stems from fear-pain-fear loops rather than physical injury
