Chunking
We process information better when put into small groups
48 people were shown 100 sets of numbers of different lengths, split up into a number of smaller chunks. After seeing each set, they were asked to recall the numbers in a memory test.
The results found that, on average, people were good at remembering about 7 numbers and 4 chunks before memory errors started kicking in.
Chunk for clarity.
Our short-term memory is limited, so whether you're designing a food menu or trying to share a new idea, prevent Analysis Paralysis by breaking information down into 3-5 smaller bites that are easier to process.
Chunk requests.
If you're asking for a lot of info from customers, how can you break the task into more manageable segments?
Data capture company, Typeform are a great example of this, turning the concept of chunking into a core USP for its data capture products.
Chunk for long-term understanding.
Boost knowledge retention by structuring each chunk learned to build upon what was learned in previous ones. Repeat past chunks to build a strong, modular connection between fragmented bouts of learning.
Language app, Duolingo does this in an engaging visual way.
Conversion
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.

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.

Time Scarcity
We're more likely to act if the clock is ticking…
90 people were asked to solve 50 puzzles in either 10 or 40 minutes. A time-saving notification stating that “This question isn’t worth any points. Press A to skip” would pop up for half the puzzles.
Results showed that the time-scarce group ironically were more likely to miss the time-saving notifications due to their heightened focus on task completion.
Time Scarcity increases conversion under a few conditions
Make sure your use of it is on-brand, authentic and not overly-aggressive to avoid harming long-term trust and loyalty.
A big clock with red flashing text may boost sales in the short-term but risks damaging brand perceptions in the longer term and will lead to Reactance in the more behaviorally-aware and in more mature markets with stronger competition.
Use time windows for excitement.
Particularly for experiments with new ideas or for seasonal Limited Editions. Starbucks’ Unicorn Frappucino was on sale for 5 days only. It sold out in just 3 and generated 160,000 Instagram posts.
Develop novel ways of saving people time.
People who spend money on time-saving purchases report greater life satisfaction (Whillans et al, 2017).
Amazon and Sainsbury’s are exploring no-queue, no-till shopping. Just scan on the app and leave. How can you free up even a few minutes of our most precious commodity?

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.
