Key ideas in Psychology of Everyday Behavior
- A lone bystander feels the entire moral weight of an emergency resting on them alone
- As a crowd grows, each person subconsciously assumes someone else has already called for help or will handle it
- Diffusion of responsibility makes people feel less personally accountable in larger groups
- In public, people reflexively hide their own alarm to maintain composure
- When everyone conceals their concern, each person falsely assumes nobody else senses a problem
- Pluralistic ignorance occurs when everyone privately worries while publicly projecting calmness
- When a crisis is ambiguous, people look to others' behavior as evidence for how to act
- Fear of public embarrassment or overreacting prevents individuals from taking the first step
- Copying a crowd's stillness is a shortcut to avoid looking foolish
- Calling out 'Someone call 911!' fails because responsibility diffuses across the entire crowd
- Singling out one person by a distinct physical trait (like clothing) pins 100% of the responsibility squarely on them
- People instinctively blame others' mistakes on personality or character flaws
- People justify their own identical mistakes using external circumstances like traffic or bad luck
- The Fundamental Attribution Error describes this automatic habit of overlooking another person's situation
- When acting, our visual attention is directed outward at obstacles and environmental pressures
- When watching others, their physical body and behavior dominate our field of vision
