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.

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).

11k people were offered a new job that had a 50% chance of doubling income for life, but it wasn't without risk, with an equal chance of it falling by either 20, 33 or 50%. Questioning started with the 33% gamble; if people took it, they were asked if they’d take the bigger 50% gamble too. But if they didn’t, they were asked about the smaller 20% one.

Results put people into four risk categories showing the majority were not willing to take any risk at all.

Focus on an improvement metric. 

We prefer the certainty of what we’re used to, so the benefits of switching to a new product need to feel substantial.

Outline a goal (relative performance, efficiency etc.) to anchor your product strategy around.

Doing so will reduce uncertainty and boost comparisons against better-known, lower risk alternatives.

Offer a trial or free sample...

...to create familiarity and reduce the risk around a new product.

This sets the cost of new product usage at zero, during which the consumer will adjust their future preferences.

Utilize your brand umbrella.

For any new sub-brands, reduce risk by clearly indicating the relationship to existing, familiar brands you own (Erdem, 1998).  

Product brands take note. Risk aversion is higher for material purchases than for experiential ones such as restaurant meals or holidays (Roche et al., 2015).

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.

42 people were either asked to make 35  'A or B' choices that would inform the design of an educational course they were attending, or instead to just read the course material. Both were then tasked with solving math puzzles and were timed until they gave up.

Those who had to make the choices beforehand persisted for less time on the puzzles and also got fewer right.

Protect your decision capacity.

Prioritize your day around and take breaks before making harder decisions. For example, restaurant inspectors can reduce errors by scrutinizing sites at higher risk of failure at the start of the day (Ibanez & Toffel, 2017).

Create product contrast.

‍When no option in a set offers a distinct advantage from the others, we're most at risk of not choosing at all (Dhar, 1997). How can you improve your choice architecture to offer variety that actually makes deciding easier? 

‍

Order matters for revenue.

‍Prospective Audi owners given a high number of customization options early on more readily accepted, higher-priced defaults in later steps (Levav, 2010). Though be careful not to trigger Reactance by pre-selecting defaults that are seen as too expensive.

‍

249 supermarket customers were invited to one of two tables, displaying either 24 jams or 6 jams. They were then asked how attractive the jams were and observed as to whether they bought one.

The results found that though customers considered the 24 jams more attractive, they were far more likely to buy when there were only 6 jams to choose from.

Reduce choice difficulty. If customers are time-poor, reduce the number of dimensions along which your products are compared. Present choices in an organised, non-random order, especially with visual layouts. 

Tidy up choice relationships. Highlight one dominant option, align the attributes along which products are compared, and eliminate products from your range that overly complement each other to decrease deferral and increase purchase likelihood.

Adapt to product expertise. Who is your audience? To what extent can they weigh up the benefits of each possible choice? Experts prefer more choice and the lesser-informed crave less.

Build around intent & focus. Intent: are they buying or merely browsing? If browsing, they’re not making a decision, and are less likely to feel overloaded. Focus: a single purchase or a bundle? Bundlers want more options, but Singles want fewer.

205 people were shown a description of a digital camera printed in a font that was either easy to read (high fluency) or hard (low fluency).

Results found that when easy to read, only 56% delayed choosing the camera, next to 71% when hard. Why? Fluency breeds familiarity, which we value greatly, because it’s unlikely to be harmful (Zajonc, 1968).

Keep it short. Whether for marketing, nudges or political persuading, low syllable, easy-to-conceptualize slogans will feel dramatically more intuitive for consumers. Next to a competing message, they’ll believe the one that’s easier to understand (Schooler & Hertwig, 2005).

Repeat. Repeat. Repeat. The mere act of repeating your message will increase its familiarity, which itself increases the extent to which it’s seen as true (Reber & Schwarz, 1999). Keep it consistent across your team and put it everywhere.

Keep product benefits concise. Consumers actually like a product less the more positive traits they bring to mind (Menon & Raghubir, 2003).  This is because they start to associate your product with greater complexity and lower fluency. 

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.

153 New York pedestrians were approached by someone dressed as either a civilian, a milkman or a police officer and were asked to help out a stranger by covering the cost of his / her parked car ticket.

The more authoritarian the uniform, the higher the chance they’d give the money. The civilian succeeded only 33% of the time, whereas the police officer managed 89%.

Determine an authority figure with relative expertise in relation to the group and behavior you’re looking to influence.

Ensure that the individual is credible and trustworthy.

Communicate their authority clearly.

For instance, using authority indicators like “Doctor,” “Judge,” “Award-winning” etc. Complementing this with a suitably-dressed photo of said individual will make any request much more effective.

Add a quotation too to bolster the effect, along with any extra reputational labels they might have (e.g. academic background, specialisms, career duration etc).

Compliance varies depending on demographics.

Older people are more compliant than younger people, for instance. For the young, use culturally-relevant aspirational models to mask authority whilst also nudging desired behavior. 

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.

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.

88 students were told about an exercise training camp and split into 2 groups: either having a choice about  the four fitness programs on offer or having one randomly assigned. They were then asked to rate their anticipated satisfaction of the program out of 9.

Those given some autonomy reported higher levels of anticipated satisfaction than those who weren’t.

Choice = autonomy = certainty. 

For instance, giving people a choice to still use the old version of your software platform for a given timeframe will reduce anxiety and uncertainty.

Product type matters.

‍People desire autonomy for pleasure purchases (i.e. vacations) more than for practical ones (i.e. business trips).

Place more focus on the former in order to maximise feelings of control and consumer satisfaction (Botti & McGill, 2011).

Change behavior with the ‘4As’.

Feeling that any change originated from within is vital.

‍Ask about the behavior, advise them impartially of the facts and of better routes, but that they must make their own choice.

If keen to change, assist them to make a commitment to do so by a given date, and arrange a follow-up to support this behavior change.

67 people were asked if they prefer Coke, Pepsi or have no preference, split into taster groups and given 3 rounds of both in either unlabeled or labeled cups.

Taste preferences were split evenly when the drinks were unlabeled, but when labeled, they exhibited a strong taste preference for Coke, underlining the bias of brand attachment in consumer choice.

Test your assumptions. Decision-Makers often start new projects under judgements that are both unproven and erroneous. Bring key Decision-Makers together to list assumptions honestly. Use these as a basis for testing the validity of the idea in its simplest form. This avoids unnecessary costs further down the line. See the Lean Startup Model for further details.

Consider conflicting alternatives to strengthen your strategic decision-making process. Seek impartial feedback from trusted others who are less emotionally invested in the chosen route than you.

Repeatedly point out what you do well, especially with attention to small details around customer care or craftsmanship in process. Consumers will begin to notice and start to look for further evidence to support these newly-held beliefs.

108 people were told they were the head of an airline that was either 90% complete on a $10m plane project, or shown an equivalent $1m proposal to research and develop this plane. In both cases, a competitor had created a similar plane of superior quality.

In either case, should they still invest the $1m? Those in the 90% sunk cost condition were far more likely to keep on spending than those who had yet to invest anything.

Remind consumers of past personal efforts or the amount of time spent with the brand to increase feelings of a sunk cost. Reframing past efforts as incomplete or as ongoing progress will also induce the effect and assist sales. 

Test your product ideas sooner using a more agile product methodology. This will minimize time, cost and effort wasted on unproven potential failures to which you will become increasingly attached, especially if you’re personally accountable for their success.

Take 15 mins for mindfulness practice - focusing on the present moment and less on the past and future - to increase your resistance to the Sunk Cost bias. (Hafenbrack et al., 2013). Check out the Headspace app.
