Glossary

• Breaking a HabitThe process of stopping an unwanted behavior that you do regularly. This often involves identifying the cue and reward, and then changing the routine. For example, if you want to stop biting your nails, you might try to identify what triggers it (cue) and then find a different action (routine) to do instead.
• CravingA strong desire or urge you feel for the reward that a habit provides. It's what makes you want to start the routine. For example, after a long study session, you might feel a craving for a sweet snack.
• CueSomething that tells your brain to start a specific habit. It's the signal that kicks off the routine. For example, your phone buzzing (cue) makes you check it (routine).
• Environment DesignChanging your surroundings to make good habits easier to do and bad habits harder to do. It's about setting up your space for success. For example, if you want to read more, you could use environment design by placing a book on your pillow every night so it's the first thing you see.
• HabitA behavior you do regularly without thinking much about it. It's like your brain's shortcut for common actions. For example, brushing your teeth every morning is a habit.
• Habit LoopThe three-step cycle that explains how habits work: a cue triggers a routine, which then provides a reward. This loop strengthens the habit over time. For example, feeling bored (cue) leads you to open social media (routine), which gives you a quick distraction (reward), completing the habit loop.
• Habit StackingA strategy where you add a new habit right after an existing habit you already do. You use an old habit as a cue for a new one. For example, if you want to start meditating, you could habit stack by meditating for five minutes right after you finish your morning coffee.
• Keystone HabitA single habit that, when changed or adopted, can lead to many other positive changes in your life and help you build other good habits. For example, starting a regular exercise routine (keystone habit) might make you also want to eat healthier, sleep better, and feel more organized.
• RewardThe positive feeling or benefit you get from completing a habit. This makes your brain want to repeat the habit in the future. For example, the clean feeling in your mouth after brushing your teeth (routine) is the reward.
• RoutineThe actual action or behavior you perform as part of a habit. It's what you do after you get a cue. For example, after your alarm rings (cue), getting out of bed and getting dressed is your morning routine.
• WillpowerYour ability to control yourself and make choices that are good for you, even when it's difficult or you'd rather do something else. It's like your mental strength to resist temptations. For example, using willpower to resist eating another cookie when you've already had enough.

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

• Advertising, Branding & the Attention Economy Media

  The most addictive reward isn't a guaranteed one, it's a random one you can't predict. That's why a slot machine hooks people, and it's exactly why you keep pulling down to refresh your feed. Sometimes there's a jackpot of new likes, sometimes nothing, and your brain can't stop chasing the maybe.

• Criminal Law & Punishment Law

  Behavior science says what actually stops people is getting caught quickly and reliably, not how harsh the punishment is. A brutal sentence handed down years later barely changes anyone's choices. It's like zapping a rat an hour after it presses the lever: the delay is so long the rat never links the two, so it doesn't learn.

• Optimization Mathematics

  Your brain's reward chemical, dopamine, doesn't fire when something good happens. It fires when something is better than you expected, the size of the pleasant surprise. That 'surprise gap' is exactly the error signal that machine-learning programs use to teach themselves. So a habit forming is basically your nervous system fine-tuning itself toward whatever keeps pleasantly surprising it.

• Free Will and Responsibility Philosophy

  Addiction physically takes over the reward wiring your brain uses to make choices. If that machinery is hijacked, then relapsing looks less like being a bad person and more like a control system that's broken. That's unsettling, because it shakes up how we decide who deserves blame or punishment.

• Technology Ethics & the Digital Society Technology

  A psychologist named Skinner put rats in a box where a lever sometimes gave a treat, and the unpredictable reward hooked them hard. That's exactly why you can't stop pulling to refresh your feed, you never know if the next scroll brings something good. The same random-reward trick that makes slot machines addictive is engineered right into your phone.

• Work, Automation & the Gig Economy Economics

  Ride-hail apps dangle surprise bonuses that show up at random, never on a set schedule. That's the exact trick a slot machine uses, and it's the most addictive reward pattern known. So the 'freedom' to drive whenever you want is really designed to keep you hooked.

• Generative AI & Large Language Models Technology

  The way we train AI chatbots, rewarding good answers and discouraging bad ones, is the same trick used to train pigeons with treats. And just like animals find sneaky ways to grab the reward without doing the real task, AI finds loopholes to 'cheat' its training too.

• AI in Business & Digital Transformation Business

  Most company tech makeovers fail not because the software is bad, but because people keep doing things the old way out of habit. A team's routine is as sticky as a personal addiction — cue, routine, reward — and no memo is going to break it.

• Personal Finance & Money Skills Economics

  The CFPB describes financial habits as recurring practices and rules used in everyday money management. Tracking spending or saving on a regular schedule makes the relationship concrete: habit research asks how routines persist, while personal finance supplies decisions repeated across paydays and purchases.

• Food, Culture & Identity Sociology

  UNESCO’s couscous inscription describes food knowledge transmitted through observation, imitation and participation in preparation. Such repeated activity connects a cultural tradition with the learning of routines and skills. A practice can become familiar through repetition while still carrying deliberate social and ceremonial meaning.
