Feedback Loops
We look for information that provides clarity on our actions
City Planners of Garden Grove, California installed Active Radar Speed Signs at 5 locations to provide real-time feedback on the speed of 58,000 drivers. LEDs would also flash if drivers exceeded speed limits by more than 5MPH.
After installation of the feedback systems, average speed dropped 22% from 44 to 34mph.
First, determine the behavior to change. Measure, capture and store the relevant data.
Communicate it back to the individual in a relevant, context-sensitive way that ultimately provokes an emotional reaction.
Provide clear consequences for action or inaction. It’s critical to get the right balance between not being too subtle and not being too intrusive or authoritarian (which we filter out).
Lastly, allow for opportunities to immediately rectify the behavior - which should also be tracked - completing the loop and eventually changing the behavior pattern. Remember to reward compliance as much as you penalize inaction to increase effectiveness.

Goal Priming
When we’re reminded of our aims, we're more motivated to reach them
The food choices of 89 people both dieting and not dieting were analyzed in a cafe. Diners were given a menu with either information highlighting low-calorie options or not (the control).
Results showed that dieters primed with the reminder of their future goal consistently made healthier food choices than unprimed dieters.
Who is the target group?
They could be people who are motivated to protect the environment, improve productivity at work or improve the quality of their lives. Note: they must have already stated a desire for this goal. Your prime will merely aim to nudge their existing Commitment to meeting their own aspirations.
Where can you trigger these long-term motivations?
As well as environment, timing also matters, so make sure that you do so very close to the actual decision point, i.e. at the start of a meeting, at the ordering counter or on the inside of a restroom door.
Boost with the Spacing Effect.
What's the specific behaviour that you're allowing them to perform to help move them towards their long term goal?
It has to be obvious and easy to do, such as clearly identifying an eco-friendly substitute, bolting on a salad or opting for an equally-priced, dairy-free option.

Present Bias
What we want now is often the opposite of what we aspire to in the future
195 students were asked to fill out a lunch order survey in return for a free lunch. They were split into two groups and asked either a few hours prior to or just before lunchtime.
Those asked with the delay made food choices 11% lower in calories than those just before lunch.
Adapt with time-to-delivery.
Online grocers could change what’s shown to the user based on how many days out their delivery slot is, showing more aspirational goods in the week prior and impulsive goods the day before.
Build around customers’ goals.
Have them make a preference on your site for their future self i.e. that they want to lose weight or save more money this year. Then, have this preference dictate what products are shown to them online, along with a subtle reminder that you’re helping with their bigger goals.
Encourage “future lock-ins.”
Banks could improve consumer savings by allowing pre-registration for a future savings account. Consider locking in other types of ‘should’ decisions that will benefit the consumer’s future well-being, as well as reducing your costs through better demand forecasting.

Salience
Our choices are determined by the information we're shown
What info we decide to surface visually has a powerful effect on peoples’ decisions. The same is also true for what we choose to hide.
For instance, if I wanted to design a work environment where people ate more fruit, I could buy bananas and apples but store them in the fridge, out of view.
But this would have what we call “low salience”, or a low likelihood of being seen.
Instead, to boost fruit consumption further, we’d want to increase Salience.
So now, instead of hiding the fruit in the fridge, we put it in large colourful bowls in central, highly visible areas of the office in eye line and within arm’s reach.
Now the fruit have “high salience” and are much more likely to be eaten.
Note that this also has second order effects; more salience from the fruit bowls means more people eating fruit, creating a powerful salience cycle.
What do you want people to do more or be more aware of? How can you increase its salience next to other things?
Another strategy is to remove other things around it to increase salience in relative terms. So in the fruit example, we might want to remove the coffee machine to give the bowls greater salience.

Over 10 days, millions of people using online ticket marketplace Stubhub were put into two groups, where 15% ticket fees were either made salient up front during ticket browsing, or hidden until checkout.
Results found that for those with delayed salience of the fee, revenue increased by 21%, with a quarter of this due to higher priced tickets being bought.
What is seen is what is done
Surfacing key information in a timely fashion can prompt us to do more of what we aspire to. For instance, Amazon have redesigned their Kindle so that when it's not in use, the screensaver becomes the cover of the book you're currently reading. This acts as a salient reminder to read as one notices the Kindle throughout the day. We can use the same approach to boost healthy eating, having a bowl of fruit on the kitchen table over one filled with salty cashews. What do you want users to do more of? How do you want them to feel? What unique or delightful features can you surface that will help inspire action and make Tiny Habits that much more likely to form?
More knowledge isn't necessarily better
There's a trade-off between what's presented to us now and making good decisions for our future. For instance, cryptocurrency exchange Coinbase choose to omit the % gained or lost from one's investments. Research shows that if they instead showed this, people may incorrectly sell coins that have increased in value, while keeping coins that have dropped in value, known as the Disposition Effect.
Differentiate by removing information
Whereas knowledge can be power, it can also demotivate. For example, weight loss scales Shapa does away with the number telling you how much you weigh, instead providing 5 colour bands denoting averaged performance. Omitting the number shifts us away from short term fluctuations in weight that can lead to feelings of failure causing us to give up. What information or options could you hide that could otherwise lead users to short term or harmful outcomes? What can you remove that could confuse or overwhelm?
Delayed salience can trigger shock
Also consider the ethical implications of hiding key information, as in the study above. In this case, any reactance felt will be relative to the proportion of the extra fees incurred, customer expectations, industry norms and how frequent the transaction is. Hidden fees on more regular transactions like grocery shopping will be subject to higher levels of reactance than one-offs like a car purchase. There is an art to surfacing such painful information at the correct time in order to generate a sale. Try adding an explanation of why the fee exists to reduce drop-off, like Airbnb do.
Pricing
Round Pricing Preference
We prefer and trust whole numbers over those ending in a 9
306 people visited one of three coffee shops and were asked to buy a coffee at either: €0.99, €1, €1.01 or an orange juice that was €0.15 cheaper than the respective coffee price.
Results showed that, contrary to conventional research on pricing (shown by the dashed line), the round-priced coffee saw the highest % of sales.
Use round prices to reduce fatigue.
There’s a growing trend for cognitive convenience in the face of Time Scarcity and Analysis Paralysis.
A banana costing £1 is easier and faster to process mentally than one costing £0.95. UK retailer Tesco now adopts this specifically for promotions.
If your brand places a value on saving time and energy, consider doing the same.
Use for premium, green or pleasurable products.
Marks & Spencer (UK), Saks (US) and Levi’s now adopt round pricing, showing the zeros. Doing so signals brand quality, warmth and trust.
Use to nudge secondary behaviors.
For transactions, add a Foot In The Door to give the rounded difference to charity (supermarket), savings (banks) or tips (fast food), for example.
Pricing
Zero Price Bias
We value something more when free over very cheap
243 people were split into four groups and asked about the attractiveness of one of two types of chocolate truffle at one of two prices (Hersheys at 0¢ or 1¢ or Lindt at 13¢ or 14¢).
Those in the zero-priced truffle group felt disproportionately more attracted to their truffle than those in all other truffle groups.
Replace very low cost with free.
Amazon famously rolled out free shipping in Europe, sales rose everywhere but France, where shipping was mistakenly set at 10¢. What small costs are you passing on to consumers?
In line with Prospect Theory, it may be better to bundle ‘the pain’ within a larger cost.
Communicate what is free.
Consider surfacing bundled, previously hidden value that you offer, actively highlighting the zero cost in marketing material and on invoices etc.
Nudge with small charges.
The flip side of zero-pricing is that incurring even a small cost quietly impacts our decisions.
If you're trying to change behaviour, imposing a small discomfort can disproportionately assist.
Conversion
Contrast Effect
We better remember products that stand out from their surroundings
40 people were split into two groups and shown a list made up of either 10 unrelated items (a number, a syllable, a colour, a word etc.), or 9 numbers and one isolated syllable placed second in the list. After a 10-minute reading task, both groups were then asked to recall the list.
Those in the isolation group successfully recalled the syllable 70% of the time, as opposed to 40% in the control.
Use complementary contrast. When showing a list of similar products (e.g. beer), weave in a contrasting product to create complementary cross-selling (e.g. nuts) or up-selling (premium beer) opportunities.
Use contrast for clarity. If you offer a range of products, draw the undecided consumer to a strategic option, preventing choice overload and assisting sales. How might customers become overwhelmed with your range? How can you create a clear sense of contrast that avoids this negative feeling?
Contrast through context. If your brand is familiar, how can you place it in relevant yet unexpected contexts to heighten recall? For instance, British food delivery service Deliveroo could have a movie tie-in shot in London, where its turquoise drivers whiz by in the background 2-3 times over the course of the narrative.
