"Loyalty programs work because they create a sense of special status and fairness, not just because of the rewards."

"The framing of retirement savings as a percentage increase versus absolute dollars changes whether people sign up."

"People are more likely to cooperate if they believe others will cooperate—expectations shape behavior."

"The sunk cost fallacy explains so much of human behavior: staying in bad jobs, bad relationships, bad investments."

"We underestimate the extent to which our decisions are influenced by factors we're not even aware of."

"Behavioral economics is ultimately about human welfare. The goal is to help people live better lives."

"The peak-end rule means we judge experiences by their most intense moment and their ending, not the average."

"People will work harder for non-monetary rewards if those rewards feel meaningful and recognizing of their effort."

"Choice architecture—how options are presented—is one of the most underutilized policy tools."

"We are all predictably biased in the same directions, which means these biases can be designed for or against."

"The default effect is so strong that even when people know better, they often stick with what's pre-selected."

"Behavioral change is hardest when it requires willpower. Make the good choice the easy choice instead."

"We care about fairness even when it costs us money. Pure self-interest doesn't explain human behavior."

"The way information is presented—positive frame versus negative frame—completely changes decision-making."

"Temporal discounting means we value immediate rewards far more than equivalent future rewards."

"To improve decision-making, focus on removing friction from good choices and adding friction to bad ones."

"People are more motivated by what they stand to lose than by what they stand to gain."

"The illusion of transparency makes us assume others understand us better than they actually do."

"Behavioral science proves that rational economic man is a myth. We're all creatures of habit and emotion."

"Understanding biases doesn't make you immune to them. You can know about availability bias and still fall victim to it."

"The reference point matters enormously. The same outcome is good news or bad news depending on expectations."

"People will often accept a sure loss to avoid an uncertain outcome, even when the expected value is worse."

"Simplicity is underrated. A simple rule beats a complex calculation for most real-world decisions."

"The endowment effect means owning something makes you value it more—a purely psychological phenomenon."

"Behavioral design can nudge people toward better decisions without restricting their freedom of choice."

"We judge situations based on reference points, not absolute values. Context is everything."

"Making something optional rather than mandatory can actually increase compliance, thanks to reactance."

"People are loss averse in the domain of gains but risk-seeking in the domain of losses. This reversal is systematic."

"The goal of behavioral economics is not to mock human irrationality but to understand and improve decision-making."

"What people care about is not just consumption but also identity and status relative to their reference group."
