3. Picture Superiority Effect

Pictures and images are more likely to be remembered than (a thousand) words.

UI tip: Always include images in your content. If you sell products or services - great visuals will improve your conversion rates.







4. Von Restorff Effect (Isolation Effect)





Design tip: Make sure the CTA button stands out using a different style, size, color, and position.



Make sure your CTA buttons stand out When multiple homogeneous objects are presented together, the object that differs from the rest is more likely to be remembered.: Make sure the CTA button stands out using a different style, size, color, and position.

More conservative than we think

We say we are innovative, we like to try new technologies, but when it comes to core instincts and quick decision making - we aim to minimize risks and stick with the things we're already familiar with.





5. Status Quo Bias

We tend to prefer a status quo over a change.

The current baseline is taken as a reference point, and any change from that baseline is perceived as a loss.





6. Endowment Effect

Once we own something, we value it higher than we did before we owned it.

As a result, we are more likely to retain an object we own than to acquire that same object if we don’t own it.

Product tip: Free trials are the most common use of the endowment effect.

Once users commit to a certain product and invest time in it (i.e. build their profile etc.) it’s harder for them to let go and not upgrade their plan when the trial ends.

Onboarding tip: Find ways for people to play with your product before signing up.

Retention tip: When a customer leaves you, provide examples of all the good things they’ll lose.





7. IKEA Effect

We place a disproportionately high value on products we created (or worked hard for).

Product tip: let your users do something as part of the onboarding process (not too hard, but rewarding) so they can connect with your product.





8. Mere-Exposure Effect (Familiarity Principle)





UI tip: Stick with familiar UI concepts, behavior, terms, signs, and icons.

Be consistent across your marketing materials, website, and product to optimize the funnel.



UX Writing tip: We tend to develop a preference for things we are familiar with.: Stick with familiar UI concepts, behavior, terms, signs, and icons.Be consistent across your marketing materials, website, and product to optimize the funnel. Align with the industry jargon . Make sure your users feel comfortable.





Stick with the standards







9. Functional Fixedness

We tend to use objects in the traditional way they were used.

Usability tip: When your product challenges an existing usage tradition - it may cause some usability challenges. Keep them in mind and try to solve them in advance.





10. Law of Instrument (Maslow's Hammer)



As they say: “To a man with a hammer, everything looks like a nail”.











We tend to over-rely on tools we are familiar with, even in the presence of much better options.As they say: “”.

Don’t call me a loser

We hate losing more than we like winning. The right message (at the right timing) might turn on this aversion and push us to make a biased decision.





11. Loss Aversion

We prefer not to lose $100 than to win $100 because the value of losing something is higher than the value of getting it (which is pretty consistent with the Endowment effect described above).



UX Writing tip: Use negative terms to express the potential loss: “stop wasting money”.

Product tip: Limit your special deals (inside and outside your product) to create a sense of urgency: “this exclusive deal ends in x hours”.



Help your users avoid losses





12. Zero-Risk Bias:



Product tip: offer money-back guarantee and risk-free trials to reduce the level of risks and make your customers feel secure.



Make sure all possible concerns are addressed



Related: 10 lessons we learned (the hard way) when we asked our customers to pay...



We love certainty even if it's counterproductive.: offer money-back guarantee and risk-free trials to reduce the level of risks and make your customers feel secure.

13. Neglect of Probability

As a result, minor risks might get overrated or neglected.

Product rule: during a conversion funnel - the smallest uncertainties might cause the user to mistrust your product and stop. Make sure all details are clear and presented upfront.

Especially the ones that involve money such as the total cost, discounts (if exists), additional costs.





Clear uncertainties proactively

When we are under pressure, we fail to think of the probability of risks to happen.As a result, minor risks might get overrated or neglected.: during a conversion funnel - the smallest uncertainties might cause the user to mistrust your product and stop. Make sure all details are clear and presented upfront.Especially the ones that involve money such as the total cost, discounts (if exists), additional costs.

14. Scarcity Effect



The fear of missing out (FOMO) makes us more vulnerable to temptation and impulse and pushes us to make rash decisions.



Product tip: decorate your products and services with “limited time offers”, “limited quantity”, etc

Create the impression that many others are watching this item “right now!” and about to grab the last remaining items any minute.



Scarcity effect in action





Or, as Booking.com would probably do it:



Scarcity effect - decepti.com style :)

15. The Simulation Heuristic



Product tip: Send a “You’re almost there!” email to users that almost completed an important action in your product, but eventually didn’t. Let them know they are very close, and that the opportunity is still waiting for them.

We determine the likelihood of an event to happen based on how easy it is to picture the event mentally. As a result, "near misses" are more disappointing than other failures.: Send a “You’re almost there!” email to users that almost completed an important action in your product, but eventually didn’t.

Disproportionately emotional

We try to make rational decisions, but sometimes our emotions are just stronger than we think.





16. Negativity Bias





1 Negative Emotion = 3 x Positive Emotion







We give more weight to bad experiences than we do to good ones.1 Negative Emotion = 3 x Positive Emotion

Product/marketing tip: Illustrate your product value by the negative experience it resolves.

If you hope your story to make an impact or even go viral - try emotionally negative content.

: Illustrate your product value by the negative experience it resolves.If you hope your story to make an impact or even go viral - try emotionally negative content.

17. Base Rate Fallacy (Base Rate Neglect)

We tend to ignore general information and focus on specific cases.

How to use: don’t just share cold information about your product. Instead, show testimonials, use cases, from people or companies others can relate with.



Work-related tip: If you want to be more convincing - blend your quantified data with some individual stories. Use quantified data to support your opinion rationally. The specific examples will convey your message emotionally.

18. Identifiable Victim Effect





How to use it: When you are telling the story of your product, use personal stories of individuals instead of generic statements.



Use personal stories instead of generic statements



We tend to empathize more with a specific individual than with a largely anonymous group.: When you are telling the story of your product, use personal stories of individuals instead of generic statements.

19. Likability Effect

We like people who like the same things we do.

As an example, if you were to tell me you’re a Transformers fan - I would immediately count you as a friend.



Marketing tip: Show the strengths of your product by using testimonials of customers who faced similar issues as other potential customers.

Make sure to use the authentic language customers are using - say it in their own words.







20. The Focusing Effect

We attribute too much weight to events of the past and translate them into future expectations.







21. Impact Bias



It’s the “I’ll never get over her!” bias.

Possible usage: Paint a picture of the users without your product or service, and later, introduce your product with how it will solve those pains.

Easily convinced

The art of persuasion! Here are some (cheap?) tricks to help you better convey your message.



22. Anchoring Effect:





How to use it: The oldest trick in the book: you add a high price as the anchor and then cross it out and set a much lower price next to it.

Looking at how Steve Jobs used it with the iPad launch I must ask: did it really work?



Steve Jobs demonstrating the Anchoring Effect



We tend to rely too heavily on the first piece of information presented to us (the “anchor”) to make subsequent decisions.: The oldest trick in the book: you add a high price as the anchor and then cross it out and set a much lower price next to it.Looking at how Steve Jobs used it with the iPad launch I must ask: did it really work?







Anchoring Effect in product pricing

Beautiful stuff... and here’s my take on the Anchoring Effect:

23. Hyperbolic Discounting





Tip: Offer a small discount (or free shipment) for immediate purchase, rather than a larger discount for future purchases.



Offer small discounts for an immediate purchase



We prefer an immediate payoff (even if it’s small) rather than a larger-later reward.: Offer a small discount (or free shipment) for immediate purchase, rather than a larger discount for future purchases.

24. Social Proof

If people like us are using it - it must be good!



How to use it: Social proof is a great way to build trust. Here are a few examples that can be used in your website, Right?: Social proof is a great way to build trust. Here are a few examples that can be used in your website, App Store product page

Well known customer logos Well known partner logos Testimonials and authentic recommendations by customers (from the target audience) Counters (number of customers, deals, sessions - whatever works) Media mentions and quotes (“as seen on…”) Awards by well-known organizations (i.e. hottest startup by WIRED) Certifications Links to case studies with actual numbers



Social Proof - Build trust using counters and customer logos













Don’t say: “we are awesome because… “, and instead, let others testify:

25. Authority Bias

We attribute greater accuracy to the opinion of an authority figure and be more influenced by that opinion (even if the subject is unrelated to the person’s authority).

How to use: Build your authority by promoting your famous references:

Contact influencers and give them free access to your product or service Highlight famous customers or brands Testimonials by famous people and celebrities Use authority figures in your visuals and statements (i.e. doctors, professors, etc.)

26. Bandwagon Effect (Herd Behavior)



We change our opinions, according to the number of people thinking the same way.



Marketing tip: convince that everyone is using your product and more people will indeed use it.

Bandwagon Effect



We often do things only because “everyone is doing it!” (Ketogenic diet anyone?).We change our opinions, according to the number of people thinking the same way.: convince that everyone is using your product and more people will indeed use it.







The “Most Popular” example



And here’s another example for the using the Bandwagon Effect in your product:

27. Belonging Bias

We are all social creatures and in order to feel part of a group we often act like other members in that group. If all the software developers are using Slack - you probably should too, right?



Copy tip: Use counters such as the number of customers, sessions, services provided, to convince the audience that your product is a standard.







28. In-group Bias





In-group favoritism also means we help members of our group more often than those in other groups.









Once we are part of a group, we almost “automatically” favor members in our group over members in other groups.In-group favoritism also means we help members of our group more often than those in other groups.





29. Not-Invented-Here Syndrome



Example: When your engineering team prefers to develop something from scratch instead of using an existing product.



Management tip: Tackle this phenomenon by complimenting your team. Their expertise is needed to develop the core of the product and their precious time cannot be “wasted” on side modules, or services that are already invented by others.

30. Belief Bias

We are more likely to accept an argument that supports a conclusion that aligns with our prior knowledge while rejecting counter-arguments to the conclusion.

Writing tip: When talking about the benefits of your product - don’t exaggerate.

If it’s too good to be true - people will not believe it.





31. Foot-in-the-door Technique





Subscription tip: Give your users a free trial to hook them up with something small.



Onboarding UX tip: Don’t overwhelm the user with over-complicated onboarding tasks.

Break it into small/easy chunks to achieve small wins and keep the user happy and engaged.





Achieve small wins during the onboarding process



A small agreement creates a bond between us and the requester and potentially makes it easier for us to agree on bigger agreements.: Give your users a free trial to hook them up with something small.: Don’t overwhelm the user with over-complicated onboarding tasks.Break it into small/easy chunks to achieve small wins and keep the user happy and engaged.

32. Variable Reward Our joy from getting rewards increases when the rewards are unexpected.

Product tip: Hook your users with daily offers, free bonuses, reputation points, prizes and more.

Not as rational as we think Make rational decisions is not as easy as it seems.

33. The Gambler's Fallacy We mistakenly believe that if something happens more frequently than normal during a given period, it will happen less frequently in the future.

Work-related tip: Stick with facts. Less intuition, more numbers.



34. Confirmation Bias: We seek and favorite information that confirms our initial belief and preconception.

Question: Did you ever manipulated your KPI reports, again and again, switching from weeks to months, from months to quarters, until finding the conclusion you were looking for?



35. Disconfirmation Bias

Question: Did you ever like a candidate (during a job interview) so much that you ignored some warning signs?



[Read: We tend to dismiss evidence that refutes our beliefs.: Did you ever like a candidate (during a job interview) so much that you ignored some warning signs?[Read: 5 product management lessons I've learned when moving from B2B to B2C 36. Framing Effect

Product tip: In most cases, positive frames (i.e. glass is half full) convert better.



A positive frame in action

Our decision-making processes are not always as rational as we think and we are influenced by the way the information is presented (positive vs negative frames).Product tip: In most cases, positive frames (i.e. glass is half full) convert better. 37. Context Effect

In visual design, a color or a size of an object can be perceived differently depending on where and how they are presented.











Our perception of things is influenced by the context in which they are presented or happening.In visual design, a color or a size of an object can be perceived differently depending on where and how they are presented. 38. Selective Perception Our perception of things is highly influenced by our expectations.

Product & marketing tip: Your product’s conversion funnel doesn’t begin when the user boards, it begins when the user sees your ad for the first time.

Misalignment between the marketing message and what the product delivers will disappoint your users and result in poor conversion rates.

Aligning the messages across all media (and stages of the funnel) will bring users with the right expectations and as a result - improve conversion rates.



39. Hot-hand Fallacy

How to use: Emphasize a list of successful stories to build your strong brand.





If Ashton Kutcher invested in this startup it must be good, right?





A fallacious belief that a person who has experienced success has a greater chance of further success in additional attempts.: Emphasize a list of successful stories to build your strong brand. 40. Anticipation: Our brain is wired to anticipate positive experiences. Anticipation contributes to our happiness.

Examples: Waiting a few months for a big vacation contributes to the overall experience. Buying early tickets to Avengers: Endgame makes us all excited and happy.

Product tip: Create anticipation for your new product (or release) by announcing it ahead of time. Create a positive buzz, something to look forward to, ensuring your audience will remain excited.





41. Information Bias

Product tip: When presenting products or services (on your website or within your product itself) - make sure to include photos of a detailed description. The more information you can pile on to product description, the greater the assurance your users will get.
