Glossary

• Anchoring EffectThis happens when your first piece of information (the "anchor") strongly influences your later judgments or decisions, even if that first piece of information isn't very relevant. For example, if a shop owner first tells you a t-shirt costs –1000, then says it's on sale for –500, –500 might seem like a great deal, even if it's still expensive for a t-shirt.
• Behavioral EconomicsThis is a field that mixes ideas from psychology (how people think and feel) with economics (how people make choices about money and resources). It helps us understand why people sometimes make decisions that don't seem logical. For example, behavioral economics explains why you might buy something just because it's on sale, even if you don't really need it.
• Cognitive BiasThis is like a mental shortcut or a "glitch" in our thinking that can make us see things or make decisions in a skewed or irrational way, often without us even realizing it. For example, if you believe a certain brand of shoes is the best, you might only notice positive reviews for them and ignore negative ones.
• Confirmation BiasThis is our tendency to look for, interpret, and remember information in a way that confirms our existing beliefs or ideas, while ignoring information that contradicts them. For example, if you believe a certain sports team is the best, you'll pay more attention to news articles praising them and dismiss any articles that criticize them.
• Default EffectThis happens when people tend to stick with the pre-selected option (the "default") rather than actively choosing something else, often because it's easier or they assume it's the recommended choice. For example, if you sign up for a new app and the option to receive email newsletters is already checked, you're more likely to just leave it checked than to uncheck it.
• Framing EffectThis describes how the way information is presented, or "framed," can change how you feel about it and the decision you make, even if the basic facts are the same. For example, you might be more likely to buy a snack if it says "90% fat-free" than if it says "contains 10% fat," even though both statements mean the same thing.
• HeuristicsThese are simple, mental "rules of thumb" or shortcuts our brains use to make quick decisions or solve problems, especially when we don't have much time or information. While often helpful, they can sometimes lead to mistakes or biases. For example, when you're choosing a new snack, you might pick the one with the brightest packaging because your brain quickly assumes "bright means good."
• Loss AversionThis is the idea that people feel the pain of losing something much more strongly than the pleasure of gaining something of equal value. We really dislike losing! For example, you might work harder to avoid losing –100 than you would to gain an extra –100.
• NudgeA nudge is a small, subtle change in how choices are presented that gently guides people towards making a particular decision without forcing them or taking away their freedom to choose. For example, putting healthier food options at eye level in the school canteen is a nudge to encourage students to pick them.
• Present BiasThis is our tendency to prefer immediate rewards over larger, future rewards, even if waiting for the future reward would be better for us in the long run. We want things now! For example, you might choose to spend your pocket money on candy today instead of saving it to buy a new video game next month, even though you really want the game.

Where this connects to other fields, and why it's worth knowing.

• Religious Conflict Religion

  Offer someone cash to give up a sacred claim, like a holy homeland, and they get angrier, not calmer. Money insults the thing they hold sacred, so a fat payout can actually blow up a peace deal. It's the exact opposite of the textbook idea that everyone has a price.

• Religion & the Sacred Religion

  Offer someone money to sell something sacred, a homeland, a child, and they don't bargain; they recoil in fury. The higher the cash, the deeper the insult. That flips every supply-and-demand curve upside down, where a better price is supposed to make people more willing, not less.

• Design Thinking Arts & Design

  Some countries have 90% of people signed up to donate organs, others barely 15%, and it mostly comes down to one line on a form: are you opted in by default, or do you have to tick a box? People almost always stick with whatever's already checked. That means the person designing the form shapes behavior more than any heartfelt speech ever could.

• Lifelong & Self-Directed Learning Education

  People skip saving for retirement because a payoff 40 years away feels fake next to a fun purchase today. You skip learning new skills for the exact same reason: the future reward feels blurry and far. This 'present bias' quietly beats the smart, patient choice almost every time.

• Narrative & Storytelling Literature

  'The economy is doomed' spreads person to person like a cold, and once enough people catch the story, they stop spending and the crash becomes real. Economists now argue that bubbles and recessions ride on contagious stories, not just cold numbers. A viral narrative can move the whole economy, because money runs on what people believe.

• Gatekeeping, Agenda-Setting & Framing Media

  '90% of patients survive' and '10% of patients die' are the identical fact, yet people make totally different choices depending on which one they hear. A psychologist named Kahneman proved our decisions flip based on wording alone. So when an editor picks which version to print, that tiny word choice is secretly a lever on how people act.

• Carbon Markets & Net Zero Environment

  Putting a price on pollution should make people pollute less. But in your head it can backfire: once you've paid to 'offset' a flight, you feel you've earned the right to consume more. So the clever fix can actually push emissions up.

• Food, Culture & Identity Sociology

  USDA research examines how food information, prices and time constraints enter purchasing decisions. Food choices therefore offer behavioural economics a concrete setting for studying attention and trade-offs: observed purchases cannot be explained by nutritional information alone, and convenience may reflect limited time rather than an irrational preference.
