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.

32 dog-phobic children were split into 3 groups and shown 8 videos of either one child playing with a dog,  many children with different dogs or no dogs, and then asked to interact with a dog themselves.

Those who watched another child play with a dog performed far better. Those who watched many children also kept this up a month later.

Provide mental shortcuts through the judgements of others; the more people, the more persuasive.  First-time consumers of your product will benefit the most from this approach. 

Persuade with similarity. We're most influenced by those who we deem similar to ourselves. Communicate characteristics relevant to that segment, such as proximity, gender / age, profession or social class to successfully direct behavior. 

Use role-models. Understand the emotional drivers of your audience and seek out positive, aspirational individuals to direct specific consumer decisions and reinforce behaviors.

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.

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).

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). 

150 teachers  in Chicago were either offered a cash incentive up front or after their students’ math test, with better results leading to more money. Subject to results, the money-up-front group would suffer deductions for unmet targets to create a feeling of loss aversion.

Teachers receiving  money up front were found to have much better results than those rewarded at the end.

Increase conversion with trial offers. Though some consumers might not be willing to pay the market price for your product, they may pay the market price to avoid it being taken away.

Offer delayed payments to shift consumers’ judgements from paying to get the product to paying to avoid losing it. For instance, a month delay in paying subscription fees. This means that any extra budgetary cost is then re-estimated as a question of how it can be fitted into an existing budget.

Replace faulty products immediately with an identical or superior model (Novemsky & Kahneman, 2005). Doing it quickly will limit the pain of loss aversion, which builds over time (Strahilevitz and Loewenstein, 1998).

274 people were shown 10 t-shirts, split into 4 groups and then asked to rate the shirts on either likeability, casualness, colorfulness or how much it matched with a cap. They were then asked how fun the task was.

Those given the ability to express their like or dislike rated the task as much more fun than the other groups. Simply, we value ways to express how we feel.

Personalization pays.

Bold, scaleable self-expressive features increase loyalty and sales.

Coca-Cola’s #ShareaCoke campaign - switching out the product name for a person’s name - led to a 10% rise in 2014 sales and a 7% spike in Facebook growth.

An Australian store sold 400,000 customized jars of Nutella for $10 each, becoming their top seller.

Tie it back to emotions.

Though there are successes like Kraft Heinz personalized soup “Get Well Soon ___”, with consumers happy to spend five times more, know that personalization has upper bounds on price and has less impact as it becomes more common.

Like Heinz, the smartest brands will tie personalization to underlying product emotions - care and sympathy in this case.

What emotions do you want end consumers to feel? Use personalization to help express these publicly.  

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.

34 people were split into 3 groups and each told to unscramble a list of either rude, polite or neutral words. After, they were told to see the researcher, who was engaged in a fake discussion with a peer. They were then timed with how long it took before they interrupted.

63% of those primed with rude words interrupted within 10 minutes, compared to only 18% of the polite group.

Prime with words that highlight the positive emotional effect of using your goods or services. For example, Spotify could prime users of its Discover Weekly playlist by using words that highlight its uniqueness or repeat gift-giving benefits.

Combine with images Coca Cola created an advert in Italy called ‘Open the happy can’ that primed potential buyers with a simple smile that was revealed upon opening. This was done in order to create an associative link between happiness and drink consumption, as well as providing a means of positive feedback for the consumer. 

 Keep it subtle. Prime too aggressively and the effect will weaken, or even lead to an unwanted Contrast Effect, where we’ll subconsciously reject and seek out opposites to the prime.

52 people were split into two groups and given IKEA boxes: either fully-assembled or unassembled that  they were asked to put together.

Those tasked with assembling their box were willing to pay a 63% premium for it during the subsequent bidding process over those given the pre-assembled boxes.

Provide personalization options early in your order flow to engender a sense of ownership and significantly improve conversion. Apple do this with their customizations for a new computer, as do new car showrooms. How can you add a low-risk, satisfying sense of creation into your existing products or services, especially around your USPs?

Don’t create choice overload and stress with too many pre-purchase customizations. Similarly, keep any post-purchase building effort simple, fun and low risk.  What core parts of your product manufacture should always remain out of customer hands?

Frame involvement as a value-add experience and not a labour-cost-saving exercise. How much this is felt may depend on your brand, your product and what you allow to be crafted by customers.
