"We overestimate our ability to control outcomes. This illusion of control affects our risk-taking behavior."

"Gift-giving creates social bonds that pure economic exchange cannot replicate."

"People value their time differently depending on context. The same hour feels different if you're paid versus if you're volunteering."

"Mental budgets are real. We think differently about spending money we've 'allocated' versus unexpected windfalls."

"The contrast effect means that the same outcome feels better or worse depending on what we compare it to."

"Cognitive biases aren't bugs in human thinking—they're often features that helped us survive."

"Reciprocity is so powerful that we feel obligated to return favors even when we didn't ask for them."

"We're not irrational actors making random mistakes. We're predictably irrational in consistent ways."

"The way you name something influences how people think about it and whether they'll choose it."

"Behavioral economics taught me that understanding human psychology is just as important as understanding mathematics."

"If you want to change behavior, sometimes the smallest nudge is more effective than a large incentive."

"People are terrible at estimating probabilities, especially for rare events or distant futures."

"The curse of knowledge makes it hard for experts to understand why non-experts don't see things their way."

"Inertia is a powerful force. Most people will stick with their current choice even if better options exist."

"We care about intention, not just outcome. A gift is worth more than its monetary equivalent."

"Regret is about paths not taken. We feel more regret about inaction than action."

"The best incentive systems acknowledge that people are not purely selfish and do care about fairness."

"To understand decisions, you have to look at the actual context in which people make choices, not just hypothetical scenarios."

"Scarcity bias makes us want things more when we perceive them as limited or in short supply."

"People are bad at understanding compound growth, which is why they underestimate both debt and savings."

"The momentum effect is real—people stick with decisions because they made them before, not because they're still good."

"If you want people to care about the environment, make the positive behavior the default, not the exception."

"Behavioral science suggests that freedom of choice is important, but too many choices can be paralyzing."

"We are all prone to overconfidence. Most people think they're above average at almost everything."

"The narrative fallacy means we create stories to explain outcomes, even when they're largely determined by chance."

"Group decisions often amplify biases rather than correct them, especially when everyone agrees too quickly."

"To change policy effectively, you need to understand not just what's rational but what's psychologically acceptable."

"The pain of losing $10 is greater than the pleasure of gaining $10—this asymmetry shapes all our decisions."

"Behavioral nudges work best when they're easy to implement and don't require willpower from the person being nudged."

"We judge our own behavior by our intentions but judge others' behavior by their outcomes."
