Scarcity
We value things more when they’re in limited supply
There’s a reason this Nugget is #1 in our library.
The concept of Scarcity lies at the core of economics, and greatly influences perceptions of value, status and our competitive desire to attain certain items over others.
Unfortunately, it's also one of the more poorly-applied concepts out there, along with Defaults and Loss Aversion.
Mastering quantity scarcity
An airline stating that there's
“Only 3 seats left” may well be using accurate data and not simply using faux-scarcity to artificially suggest that there's less supply of seats than there actually is.
However, from the user's perspective, the buildup of mistrust around the use of scarcity means cynicism is higher, so one must be careful with information presented.
Similarly, hotel websites telling you that “30 other people are looking at this item” engineer stress to compel people into action without changing supply yet highlighting demand in a manipulative way.
Instead, use quantity scarcity to focus on the craft and high quality of what you're selling.
Make your scarcity feel valuable, not stressful.
Mastering time scarcity
Ensure that any time restriction is highlighted primarily for the purpose of maintaining the quality of your product or service, and not merely to cause stress that could be avoided.
As an example, use time scarcity to launch unique or experimental products that are only available within a particular window (say a week, month or season).
This use of time scarcity is positive and encourages brand exploration, used creatively to highlight your unique value.

146 people were asked to rate identical cookies that were either presented in a jar as scarce or in abundance. They were then asked how likely they would be to want to eat a further cookie.
When scarce, the cookies were rated as more desirable and having a higher value. They were also seen as more valuable when going from an abundant state to scarce than when always scarce.
Scarcity comes in 4 flavors:
Quantity, Time, Access & Rarity.
Control quantity.
To increase perceived value of your product, release it in smaller and diminishing quantities, emphasizing its finite nature.
Restrict time.
When the clock is ticking and we’re overwhelmed, we take mental shortcuts that speed up decision-making.
Motivate customers by emphasizing the limited time remaining in which to act.
Limit access.
Restricting access to your products or services will increase desire and perceived value. Do this selectively for certain features and / or customer segments.
For instance, you might want to design valuable, unique rewards that are only unlocked for very special efforts on the part of the customer.

Zeigarnik Effect
Incomplete tasks weigh on our minds until done
47 subjects were given around 20 small, manual tasks to complete, one at a time. Experimenters randomly interrupted completion of half of these tasks. After, subjects were asked to recall as many tasks as possible.
There was a 90% higher recall of incomplete and interrupted tasks than those completed.
Make important task completion frictionless. If customers leave your site without finishing their order, make it effortlessly easy to get that completion feeling, such as allowing for completion with a single click, tap or swipe.
Focus on completion’s emotional release. Providing reward incentives for task completion actually demotivates consumers. Instead, remind them not just of the product they’ve not yet bought, but of the feelings that this ‘purchase task’ will unlock.
Make known campaigns incomplete and interactive. Greater familiarity with an advert increases consumer ability to complete an interrupted ad message. Active participation also boosts ad memory (Heller, 1956). So if your popular campaign’s reaching its end, consider a special second follow-up version that allows for active participation in completing the ad message.

Framing
We make very different decisions based on how a fact is presented
Information has a wonderful way of looking very different, depending on how it’s communicated.
From turning glasses half empty into those half-full, as Designers, we have a great role to play in using framing to help people see things differently and hopefully, for the better too.
Framing is one of your most powerful behavioral tools. Everything can be reframed, depending on what you want.
For example, online second-hand clothing marketplace Vinted has devised a clever strategy to reframe the commonly-used “Service Fee” as a “Buyer protection fee”.
By reframing it as buyer protection and clearly communicating how this amount is calculated, this assurance goes beyond merely paying for the item.
Now, customers will also feel confident that they’re taking extra steps towards safeguarding their purchase.

96 people were told they’d be given some ground beef to taste, with half told it’d be “25% fat” (negative frame) and half told it’d be “75% lean” (positive frame). They were then asked to rate the quality of the beef out of 7.
Those presented with a positive frame rated the beef as higher quality than those presented with a negative one.
Create a frame using context, words or imagery to help others to see things according to your needs.
Wildly different perceptions are made possible by reframing the same evidence.
Reframe statistics as factually-accurate positives against competitors.
Facts are dramatically reinterpreted when set amongst different data.
• Create an opportunity to act.
We’re more likely to take up a special offer when the marketing message is framed as a potential loss than a gain (Gamliel and Herstein, 2012).
Product Development
Picture Superiority Effect
We remember images far better than words
142 people were split into 3 groups and were shown either 72 nouns, abstract words or pictures on a projector for a split-second each, with 5-second pauses in between. They were then asked to recall as many items as possible.
Results showed that those in the picture group recalled far more than either word groups.
Boost your message.
Visual ads are remembered better in the long term than verbal ads, especially when we are under greater cognitive load (Childers and Houston, 1984).
What emotional message can you convey more powerfully with a striking, visual metaphor over mere words?
Boost learning by adding in visual references, and not relying solely on text-based language.
This can help broaden understanding across cultures and age ranges.
Where are you trying to change behavior?
What image do you want to stick in peoples’ heads to simplify understanding?
Make product choices distinct.
Images are internalized twice, both visually and verbally (see Dual Code Theory), so they stick in the brain better than just words.
This holds as long as the images aren't abstract or similar to one another (Reder et al, 2006).
So if you sell a large product range that looks similar, consider modifying their design or how they're presented to heighten relative differences and create a more distinct range of choices.

Default Effect
We tend to accept the option pre-chosen for us
Faced with a set of options, when we’re not sure what’s the “right” choice, Defaults offer a helpful guide.
They help people avoid expending vast amounts of cognitive energy to decide between what could be a large number of options.
This is especially the case for those who don’t know much about the products or services, where Default options can take away the fear of getting that first decision wrong.
They're also a powerful remedy to any potential Analysis Paralysis, and are particularly helpful when making multiple choices one after the other.
Consider that you’re buying a computer, with a range of possible customisations to various parts.
If there were no default choices set, we’d quickly become overwhelmed with what was the right choice in each step.
If you have complicated product ranges or customisations, are you setting helpful Defaults? If you are, think hard about whether these need improving to reduce effort further.
But also, a word of warning.
Defaults can be terribly misused to force people into decisions that they don’t want.
Take people down the wrong path and you’ll quickly trigger Reactance; an angry feeling where people will want to reclaim their independence, often doing the opposite of what you Default them to.
Ensure that your Defaults have peoples’ own intentions in mind and don’t deviate too far from what people would do of their own choosing.
What Defaults are you setting? How can these be improved to help smooth out decision-making and guide people to better outcomes, either for themselves (e.g. helping them save more money) or for the wider group (e.g. defaulting meeting times to 15 minutes instead of 30).
Defaults are set everywhere. They’re powerful and have a big influence on behavior with little effort.

161 people were told that they’d just moved to a new US state and that here, the default was (or wasn’t) to be an organ donor. They were then asked to accept or change this donation status.
Results showed that only 42% donated when the default was to opt out, but 82% when defaulted to opt in.
Defaults are powerful. They’re chosen because consumers take mental shortcuts (especially when tired) and because there’s implied trust that they’re the ‘right’ choice. Defaults also act as a reference point against better or worse options. (Dinner et al., 2011).
Defaults can be set around anything: from the standard package you offer to new subscribers, to the pre-set top-up amount for your mobile wallet, to whether each order of pizza should come with salad. Each default can dramatically affect conversion levels and behavior.
Get the balance. Ensure your defaults feel natural and in line with consumer aspirations. The more extreme the default you set (i.e. defaulting to the most expensive option), the more effort consumers will expend weighing up the cognitive / emotional costs of not choosing the default, impacting their experience and reducing overall trust.
Experience
Prospect Theory
A loss hurts more than an equal gain feels good
You’re walking down the street. Consider two realities:
A: You unexpectedly find $10 in your pocket.
You feel positively-surprised!
Or:
B: You left the house with $10 in your pocket.
But you reach in and it’s gone.
The pain you feel from its loss is greater than the good feeling of finding it.
Prospect Theory explains that our perceptions of value differ based on how something is framed, and losing things feels worse than getting them feels good.
As one of the grand concepts that underpinned a lot of the early ideas within behavioral science, Prospect Theory is a beast with many aspects to it, such as Loss Aversion, Framing, Certainty, and Risk.
But for now, take your practical understanding a step further by reading the Aggregation Effect and Segregation Effect Nuggets.

But for now, take your practical understanding a step further by reading the Aggregation Effect and Segregation Effect Nuggets.
Prospect theory is explained with a graph. Negative losses and positive gains recorded on the horizontal are set against a vertical intensity of feeling for those losses or gains.
As we gain more, we feel less for each gain. In contrast, even a small pain (shown in red) feels a lot more negative than an equal-sized gain feels good.
Package pain. Consumers will feel less overall pain from any costs incurred when you package and deliver them all together rather than when they're felt as separate, smaller pains.
Spread out rewards.
Instead of offering larger, chunkier benefits to consumers, break these down into smaller pieces, spreading them out across time.
$10 given 4 times feels more valuable overall than $40 given once.
Offer mixed product bundles.
We feel less good with each thing we consume. Therefore, the first can of soda tastes better than the fourth.
This means we'd get more complimentary value from a bag of chips instead.
Look for ways to offer relevant, mixed product bundles to offset diminishing consumer sensitivity.
Experience
Certainty Effect
We crave clarity over chance and make costly sacrifices to get it
77 people were asked to choose between an entirely certain win of $30 and an uncertain 80% chance of winning $45.
78% of people opted for the significantly smaller, certain reward, despite the risk-adjusted payout being higher for the uncertain reward (0.8 * $45 = $36).
Certainty is valued highly.
What ways can your business create reassurance or guarantees that make consumers feel safe? How can you use exclusive certainty to reward and foster a sense of status with your brand?
Stick to your promises!
Letting consumers down, even once, will trigger uncertainty in the quality perceptions of your brand. If making claims about being the best at something, don’t ever give consumers reason to question that and turn a selling point into an unsustainable headache.
Reframe uncertain offers to appear certain.
The uncertain frame here requires consumers to calculate proportional savings, but the certain frame removes this by showing certainty of a zero-priced third lemon.
Loyalty
Reciprocity
We’re hardwired to return kindness received
We call Reciprocity the glue that binds us as a society.
No surprise then that it’s a powerful tool to help people make decisions that are both pro-social and a win-win.
When the Behavioural Insights Team were asked by the UK Government to increase the rates of job-seekers turning up to interviews, they applied the principle of Reciprocity to boost rates.
They changed the text message being sent out from:
“You’ve been booked an interview at Tesco on Friday at 10am”
to:
“Dave,
I’ve booked you an interview at Tesco on Friday at 10am.
Good luck.
Roxy”
This shift from a passive tone of voice to an active tone, where Roxy had done something kind for you (and you then wanted to reciprocate by turning up), increased attendance from 10% up to a whopping 27%.

407 pedestrians in Brittany, France were approached by a young woman and asked to complete a survey. Before the request, half were offered candy and the other half were not.
The results found that people - especially women - were far more likely to reciprocate and answer the survey after receiving a gift than when not.
Act first.
Find ways to initiate reciprocity with consumers. Merely asking those satisfied to go tell their friends will work (Söderlund et al., 2015).
Make it a ‘common habit’.
When we’re told that a behavior is a social norm shared by others, we’re more likely to reciprocate. Households in USA and India consume significantly less electricity when told that their neighbors are consuming less (Sudarshan, 2014). In the long-term, any consistent, successful behaviors will be adopted as the default for others.
Do it in person.
Reciprocation appears to be more powerful when requests from strangers are made face to face rather than online. This is due to the persuasive impact of immediacy that physicality affords, the higher levels of digital suspicion and the sheer number of emails people receive (Meier, 2016).
Product Development
Availability Bias
Our judgements are heavily influenced by what comes to mind more easily
36 medical students were first asked to diagnose six clinical cases (Phase 1). They were then asked to diagnose a further eight, four of which were similar to Phase 1, but were actually different (Phase 2). Their accuracy for successful diagnosis was rated out of four.
Average diagnosis scores were 17.5% lower for Phase 2 cases that were similar to those in Phase 1.
Create pre-experiences.
During product development sessions, prime attendees with prototypes to first tell a detailed story of an imagined future. This will increase innovative ideas by reducing both incremental thinking (Liedtka, 2015) and inferior ideas brought about through Ownership Bias and any Sunk Costs.
Conduct reflective reviews.
After results are in from product experiments, reviewing the specific causes behind both failures and successes is critical. This will help you understand any assumptions or misdiagnosis brought about by merely relying on what comes easily to mind (Ellis and Davidi, 2005).
Include real customers in retrospectives.
Combining reflective reviews with real customer feedback will boost team performance (Schollaert, 2009) and help suppress the perils of your team's own Confirmation Bias.
