  Social proof

  People look to what others do to make decisions, especially when uncertain. In an interface, that means showing real evidence - like ratings, usage counts, and reviews - from actual users.

  Scarcity

  Scarcity increases appeal by making something feel more valuable when it appears rare or about to disappear - like 'only 2 left' or 'offer ends in 5:00'. It works because the discomfort of losing an option outweighs the pleasure of gaining one.

  Reactance

  Reactance is the push-back you feel when something threatens your freedom to choose. Tell people they must do something, or that they can't have it, and the heavy-handed pressure itself becomes a reason to resist - so hard sells, forced steps and "you have to" framings often produce exactly the behaviour they were trying to prevent.

  Fresh-start effect

  The fresh-start effect is our boosted motivation to pursue goals at moments that feel like a new beginning - a Monday, the first of the month, a birthday, the new year. These temporal landmarks create a psychological line between an old, flawed self and a fresh one, making it feel like the perfect time to start over.

  Temptation bundling

  Temptation bundling is pairing something you should do but tend to avoid with something you want but feel you shouldn't overdo, so the two together become genuinely appealing. Only letting yourself watch your favourite show while on the treadmill, or saving a great podcast for the commute, turns a chore into something you look forward to.

  Streisand effect

  The Streisand effect is the way trying to hide, remove or suppress information ends up drawing far more attention to it than ignoring it ever would. The act of suppression signals that something is worth seeing, provokes reactance, and often spreads the very thing you wanted buried.

  Provide exit points

  Providing exit points means deliberately giving people clear, graceful moments to pause, save or leave - so they stay because they want to, not because they're trapped. Natural stopping places, an obvious way out, and "save and finish later" options respect the user's autonomy and, paradoxically, tend to build the trust that keeps them coming back.

  Delighters

  Delighters are small, unexpected touches that surprise and please, making a product feel thoughtfully crafted - like a witty empty state, a satisfying animation, or a well-timed surprise. In the Kano model, they’re features nobody asks for, and their absence is rarely noticed - but their presence builds affection and warmth.

  Noble edge effect

  The noble edge effect is when a brand gains an advantage by visibly acting ethically or generously: its social responsibility makes people view its products more favourably, trust it more, and prefer it over rivals. Doing real good gives the brand a 'noble edge' that influences how its entire offering is judged.

  Shaping

  Shaping is building a complex or daunting behaviour gradually, by rewarding small steps that get closer and closer to the target rather than demanding the whole thing at once. Instead of asking someone to do the big hard thing immediately, you reinforce successive approximations - each easy win making the next step feel achievable.

  Investment loops

  Investment loops are the part of a habit-forming product where the user puts something in - data, content, effort, social connections - that makes the product more valuable to them and loads the next reason to return. Each bit of investment stores value and sets up the next trigger, so the loop pulls people back over time.

  Triggers

  Triggers are the prompts that start an action. External triggers come from outside - a notification, email, badge or button telling you what to do next. Internal triggers come from within - an emotion, routine or association that makes you reach for the product unprompted. The goal of habit-forming design is to move people from needing external nudges to acting on internal ones.

  Anchoring

  Anchoring is the tendency for an initial value or reference point - often but not always a number - to influence later estimates and judgements.

  Loss aversion

  Loss aversion is the way losing something tends to hurt more than gaining the same thing pleases. A common rule of thumb puts losses at about twice the weight of equivalent gains, though the size varies substantially by method and context; the effect itself is well evidenced. The maths can be identical while the feeling is not, which is why "don't lose this" often pulls harder than "get this".

  Framing effect

  The framing effect is how the same fact, described positively or negatively, lands differently - "90% fat-free" feels healthier than "10% fat" though they are the identical tub. We react to the spin as much as to the substance.

  Reciprocity

  Reciprocity is the natural tendency to return a favour: give something of real value first, and people feel quietly obliged to give back. Start with real value, and a later ask feels gentle; if you begin with the ask, it sounds like a demand.

• persuasion

  Authority

  Authority is our tendency to trust and act on advice from a credible source - an expert, a credential, or an official badge. The same claim carries more weight when it comes with a reason to believe the person making it.

  Unity

  Unity is the pull of shared identity - we’re more readily persuaded by people we count as one of us. Not just 'people like me do this' (that’s social proof) but 'we are the same kind of person', a family, a profession, or a tribe.

  Social proof vs authority

  Social proof says 'people like me do this'; authority says 'a credible expert or institution recommends this'.

  Goal-gradient effect

  The goal-gradient effect shows how motivation increases as you near a reward - people tend to push harder in the final stretch than at the start. Showing visible progress, even a small head start, makes the goal feel within reach, so people keep going.

  Variable reward

  A variable reward is a payoff that arrives unpredictably - sometimes big, sometimes nothing - rather than consistently. That uncertainty drives more repeated action than a predictable reward of the same average value. It’s the engine behind slot machines, social feeds, and the endless pull-to-refresh.

  Decoy effect

  The decoy effect occurs when adding an asymmetrically dominated option - clearly worse than one choice but not worse than every alternative - makes the option that dominates it more attractive.

  Commitment and consistency

  People feel a strong pull to act in line with what they've already said or done. So a small, early commitment - a tick, a tiny first step, a stated preference - makes a larger, consistent request far easier to agree to later. It's the "foot in the door": the first small yes paves the way for the bigger one.

  Sunk cost fallacy

  The sunk cost fallacy is letting money, time or effort you have already spent - and cannot get back - keep you committed to something that is no longer worth it. The only sound question is what the next step is worth; the fallacy answers a different one - what you would be "wasting" by stopping.

  Liking

  Liking is Cialdini’s simplest principle: we say yes more easily to people and brands we like. Similarity, sincere compliments, shared goals, familiarity, and warmth all build liking - and liking, in turn, lowers resistance to a request. We agree with those we feel good about.

  Sunk cost fallacy vs loss aversion

  Loss aversion makes losses feel heavier than gains; the sunk-cost fallacy lets past costs steer your next move, even when they’re irrecoverable.
