@jennyshen Loss Aversion : • Frame gains and losses to make some options seem more desirable than others

@jennyshen Applying Loss Aversion : • Limited time discounts • Trial periods • Lazy registration What is lost by leaving your product/service?

Endowment Effect : We place greater value on objects if emotional value has been invested

@jennyshen • Encourages purchasing or other behavior • Infers value and exclusivity • Why it works: humans use an item’s availability to quickly determine its quality and value. • The scarcity principle   is a shortcut for us to make quick decisions • Scarcity works most when it’s created by social demand Scarcity :

@jennyshen • Time-based scarcity : holiday sales, coupons with expiry date, limited time offers • Stock scarcity : highlighting remaining quantity or highlighting limited quantity available • Restricted access : paywalls, member-only content Applying Scarcity :

Completion : Provide a well defined end-goal and progress to give a feeling of closure

@jennyshen • As humans, we have an natural tendency to avoid doubt and uncertainty • The need for closure   drives us toward a well defined end-goal Completion :

Variable Rewards : The   sense of scarcity and unpredictability entices users curiosity in discovering the pattern

@jennyshen • Compared to fixed rewards, variable rewards produce the highest activity in users • Humans react differently to certain patterns of rewards. Studies concludes that variable reward schedules and contingencies motivate us more than fixed schedules and contingencies. Variable Rewards :

@jennyshen • Give out rewards at variable ratio and interval • Random and unexpected bonus and rewards: upload quota bonus, gift for community engagement, secret badge, spin to win Applying Variable Rewards :

Authority : Humans have a strong tendency to comply with authority figures

@jennyshen • We see information from a recognized authority as a valuable shortcut for deciding how to act in a situation, with little or no consideration • People trust authorities, their taste and often believe that it fits their own • Humans are vulnerable to the appearance of authority, even if there’s no real authority Authority :

@jennyshen • Certifications and awards • Logos or names of known companies • Associate your product/service with authority figures in your industry Applying Authority :

Social Proof : Humans have a common tendency to adopt the opinions and follow the behaviours of the majority to feel safer and to avoid conflict

@jennyshen Social Proof : • We believe that acting in accord with social evidence is a shortcut to correct behavior and good decision • Most of us would rather imitate that initiate • We often resort to short-cutting our thought processes because thinking and decision making requires brain energy

@jennyshen Source: joeydevilla.com, pjrvs.com, Usabilla, Booking.com

@jennyshen Applying Social Proof : • Use numbers from facts or statistics, e.g. 14 reviews, 80 people liked this, 590 subscribers, 200+ clients • To assure users that they are not alone in the decision, highlight what others similar to them did, e.g. “others also bought / viewed this listing” • Testimonials and ratings

@jennyshen Persuasion Design Ethics : • Everyone’s scale of ethical/unethical is different • Persuasion is subjective • What we don’t like is when companies manipulate us into doing things we later regret

@jennyshen Persuasive design is not unethical , unless one intentionally deceives user or takes away user’s freedom to do something against company interest. “ ” —Jenny Shen
