Marketing, measurement and the irrational mind A beginner’s guide to behavioural economics Behavioural economics is turning heads within the marketing community. Most agree the story is compelling: much human decision-making is automatic and irrational, so small changes to communications and contexts can have a striking impact on how people behave. But the reality is fuzzier. Exactly how is it applied and where does it fit into next quarter’s strategy? In this guide we look past the anecdotes, debunk some myths and define the role of behavioural economics in creating a measurable impact on ROI. ©Copyright PrimeDecision 2012 Chapters 1 Executive summary 2 Behavioural economics 3 Common misconceptions 4 Evidence-based marketing 5 Application: Seven Lenses 6 Pitfalls to avoid 7 Conclusion: Creativity ©Copyright PrimeDecision 2012 Executive summary #1 Behavioural Economics (BE) is a relatively new discipline, with popular understanding still limited to a handful of memorable anecdotes. This makes for punchy Ted Talks and decent dinner party chat, but means it has scant bearing on the day-to-day activities of most marketers. In this paper we clearly define where BE thrives: in a measurement-focused, experimental marketing environment. The core premise of BE is that human decision-making is affected by a range of psychological biases, which mean that the context of a decision can substantially shape the outcome. How an offer is framed, for example, is one of a collection of factors which affect how people behave. So by methodically crafting communications to match these psychological tendencies we can become more effective in influencing how customers and prospects act. A behaviour-led approach benefits organisations in two key respects: BE is a catalyst for experimentation. It invites a more rigorous, scientific approach to enhancing the performance of marketing activities. BE equips marketers with proven, evidence-based insights about human decision-making. Its frameworks and principles can be used to for optimisation – informing incremental changes which improve response rates, or can be used more extensively – fuelling innovation across the organisation. Psychological insight has long been considered a fundament of marketing. But in behavioural economics we have an incarnation well-suited to the accountable, target-driven landscape in which we operate. ©Copyright PrimeDecision 2012 Behavioural economics (BE) may be the term which has caught on, but it is just one of a series of disciplines and fields of study which are making strides across similar terrain – such as Neuropsychology or Judgement and Decision-making (JDM). In this document, we use BE as a convenient shorthand to talk about the behavioural sciences, all of which provide insights into the psychological tendencies which underpin human decision-making. ©Copyright PrimeDecision 2012 Behavioural economics #2 Conventional marketing approaches tend to focus on winning ‘hearts and minds’, providing emotional and rational reasons to buy a product or act in a particular way. Behavioural economics is different: it is focused on the automatic responses and mental processes that underpin behaviour in a particular moment. One experiment asked different groups of people to: a) b) Choose a piece of art to keep Choose a piece of art to keep – plus explain their choice When able to choose freely, a greater percentage opted for the abstract work. But if also asked to explain the decision, more chose the figurative piece, which is arguably easier to justify.1 The pressure to explain the decision actually changed the decision. This supports the need to arm buyers and influencers with justifications that are easily assimilated and repeated. But it also cautions us to treat customer feedback with care, for self-aware reasoning is only part of the story. Many of our choices and actions are more automatic than we realise. 1 http://prime-decision.com/uncategorized/decision-making-dynamics-the-role-of-justification/ ©Copyright PrimeDecision 2012 Decision-making is an exhausting business. BE teaches us to think about the brain as an energy-efficient machine, which aims to avoid effortful thought where possible. Consider how many choices are made every day. Every search term and shopping aisle provides us with a baffling range of possibilities. And even the most complex decisionmaking processes are littered with micro-decisions about where to click and what to read. The brain’s response to all this choice is to rely on rules of thumb (or ‘heuristics’) to make fast, effective decisions. This eliminates the energy consumption required for conscious, deliberate reflection, enabling us to make choices with minimal effort. Although we are unaware of them, these mental shortcuts play a significant role in our everyday choices. Through studies and controlled experiments, researchers worked to unravel these mental factors, teasing out the different tendencies involved. This revealed recurrent patterns in the ways that humans approach choice. Of course the tendencies themselves aren’t new, but the rigour of our understanding is – and continues to become more refined. These principles are the foundation of BE. ©Copyright PrimeDecision 2012 Rational versus irrational A central theme in the BE story is the concept of irrational decision-making. The field of behavioural economics challenges economic models based on concepts such as homo economicus; that humans are rational agents making decisions which maximise utility.2 Psychologist Dr Daniel Kahneman earned the Nobel Prize for Economics for his work with Amos Tversky, demonstrating how investors make irrational decisions.3 Their studies showed how perceptions of value change according to context: people incline towards risk-averse behaviour in relation to gain and risk-seeking behaviour in relation to loss. Even financial judgements are biased by numerous factors, from loss-aversion to past experiences. An irrational fear? Hearing that we don’t always act rationally may feel uncomfortable, for the term ‘irrational’ is associated with being unreasonable or unpredictable.4 But these biases have evolved because they are so useful. For instance, when choosing a food stall at a festival, it makes sense to go with the herd5 and join the longest queue. This is not strictly rational, but it is a reliable strategy in a world in which we have incomplete data and limited time. Some leading cognitive psychologists argue that relying on frugal, fast methods of decision-making can actually be more effective in achieving positive outcomes.6 In an uncertain and unstable world, strategies like following the advice of a trusted elder or acting on the basis of an old habit can prove exceptionally valuable. 2 Rittenberg and Trigarthen. Principles of Microeconomics: Chapter 6. pp. 2, Accessed June 20 (2012) http://www.apa.org/monitor/dec02/nobel.aspx 4 Oxford Dictionary defines irrationality as ‘not logical or reasonable’; the definition of unreasonable is: ‘not guided by or based on good sense… beyond the limits of acceptability or fairness.’ Oxford English Dictionary, oxforddictionaries.com/definition/english/unreasonable 5 Mark Earls, Herd: How to Change Mass Behaviour by Harnessing Our True Nature (2009) 6 Dr. Gerd Gigerenzer, Max Planck Institute: http://gocognitive.net/video/gerd-gigerenzer-bounded-rationality 3 ©Copyright PrimeDecision 2012 Some examples of heuristics in practice: BE principle: social norms Reframing hotel signage increases the number of customers re-using their towels. One study found that the copy ‘Please re-use your towels to help save the environment’ could be bolstered by adding that ‘Most previous occupants of the room re-used their towels during their stay’. The small copy change set a social norm which increased the number of customers re-using their towels from 35.1% to 49.3%. The trial also found that referencing the specific room had greater impact than referring to ‘other customers’ of the hotel.7 Key concept: social approval Smiley faces prove effective in slowing down drivers, at a fraction of the cost of standard speed cameras. We are often highly responsive to how others view us, even when the ‘other’ is a representation. This is well-illustrated by vehicle-activated signage which displays your speed along with a corresponding happy or sad face – encouraging people to slow their driving speed. When faces were introduced to cameras by South Lanarkshire Council, speeding fell by 53%.8 Key concept: anchors Complex decisions such as credit card repayments can be steered by seemingly minor pieces of information. In the process of decision-making, the brain latches onto certain pieces of information, known as ‘anchors’. The minimum payment acts as an anchor in credit card repayments, so affects what people choose to pay off. For instance, on an average bill of £435, people with a 2% minimum payment paid off £99 each month, while people without a minimum payment paid off £175.9 7 Cialdini (2003) Crafting normative messages to protect the environment.

Psychological Science 20:39-41 ©Copyright PrimeDecision 2012 Bias is inherent in the design of services and communications, whether or not the creators are aware of it. Default settings are a well-documented illustration of how choices can be influenced radically from the outset. In countries like France and Hungary where the default for organ donation is to be automatically opted-in, only 5-20% of the population opt-out. Conversely, in countries which require people to opt-in, the numbers are flipped: fewer than 20% opt-in.10 The UK is soon to trial a middle-ground approach which obliges people to make a decision about donation when applying for a driving license, preventing them from acquiescing to the default.11 10 Organ Donation Taskforce, The potential impact of an opt out system for organ donation in the UK: An independent report from the Organ Donation Taskforce (2008) 11 http://www.direct.gov.uk/en/Nl1/Newsroom/DG_198724 ©Copyright PrimeDecision 2012 Common misconceptions #3 Equating BE with anecdotes Behavioural economics provides us with some terrific anecdotes. Did you hear the one about the detergent in the canteen? The one about the urinals? Or the mirrors and the slow lift? It’s compelling that exposure to the smell of detergent in a canteen can prime people to keep their tables clean12 or that painting a fly on a messy airport urinal would compel men to improve their aim and reduce spillage. And when faced with complaints about lift speeds and waiting times, rather than investing in expensive lift refurbishment, what a stroke of genius to put mirrors by the lift doors, causing people to preen and lose track of time!13 The field is packed with memorable outcomes – and these can be very useful in explaining behavioural economics to newcomers. But if we stop there, we limit our understanding of behavioural economics to flashbulb moments and happy accidents. On the other hand, some applications of BE are so entrenched that their insights are taken for granted. For instance, all property owners know that the aromas of coffee and apple pie will prime prospective buyers to feel more at home. Yet despite seeing the value first-hand, people don’t conceive of BE as adding value to the kinds of problems faced in a marketing context. Supermarkets, maybe, but automated marketing touch-points in B2B? 12 Holland, Hendriks, & Aarts, 2005, in Dolan et al (2010) Rory Sutherland, presenting to Creative Directors Network, Bristol (http://primedecision.com/uncategorized/rory-sutherland-on-be-part-2/) 13 ©Copyright PrimeDecision 2012 Spend any time with academics studying neuropsychology or judgement and decision-making (JDM) and you learn a different side of the story. Far from one-off flukes, the behavioural sciences are built around processes and rigour, randomised controlled trials and the pursuit of repeatable outcomes. This is the model that marketing can really learn from. There is still room for innovation, but it is a disciplined approach to experimentation that enables behavioural economics to flourish. ©Copyright PrimeDecision 2012 Heuristics are not silver bullets. Even the world’s leading neuroscientists still know only a fraction of what there is to understand about the human brain. The complexity is staggering and the recent tendency to hold neuroscience up as having all the answers should be challenged.14 Countless factors converge to inform our decisions. Heuristics are overlapping and can be conflicting. For example, scarcity effect might motivate someone to pursue an object or experience which is rare or likely to run out, such as the last product in stock, but that same person could equally be swayed by primacy effect, in which their first experience of the product biased their choice. Marketers should not expect to tweak a copy line based on heuristic X and magically transform conversion rates; knowledge of heuristics simply underpins smart choices about what might be most impactful and what should be tested first. 14 http://www.guardian.co.uk/science/2012/apr/29/neuroscience-david-eagleman-raymond-tallis ©Copyright PrimeDecision 2012 Evidence-based marketing #4 BE doesn’t transform marketers into Derren Brown. It simply informs improvements to existing activities through useful insights and perspectives. But it’s combining these principles with more methodical practices and a focus on experimentation which generates the improved performance we all seek. Measurement: the foundation In this era of data, measurement is what differentiates leading organisations from the rest. There is a significant body of evidence indicating that the best-performing marketers are better at quantifying their contribution to the business – whether in the form of qualified leads, pipeline or revenue. Research shows that 81% of best-inclass marketers can identify their most and least profitable campaigns, compared with 41% of average companies and just 15% of worst-performing organisations.15 Getting baseline metrics in order – and the associated processes – are the bedrock for improving outcomes through experimentation. Repeatable processes are perfect problems for BE to tackle. A sign-up process, a cross-sell touch-point, data capture forms and regular communications all have a clear business-case for improvement and the potential to test, improve and scale. A few percentage points in the right place make a tremendous difference in the longterm, eclipsing the investment in optimisation. 15 Trip Kucera, Marketing Lead Management, Aberdeen Group (2012) ©Copyright PrimeDecision 2012 Small tweaks, big difference One of the advantages of BE is that the changes can be very cost-effective to implement, such as testing several different versions of a letter or email. Barriers to purchase are an obvious focus for website optimisation and ecommerce. One company increased customer purchases by 45% after removing the requirement to register or enter a password before checkout – generating an additional $300,000,000 in revenue during the first year. 16 Although this may seem like a no-brainer, many organisations fail to question existing practices. The UK government is reporting success in taking an iterative approach to improving the response rates of direct communications. The Cabinet Office’s Behavioural Insights Team (aka the Nudge Unit17) sent out several versions of tax repayment letters in order to test the impact of social norming on influencing people to pay their tax. They found that stating in the letter that most people in the local area had already paid their taxes boosted repayment rates by around 15%.18 They also found referencing the closest town or city to be more motivating than postcodes. Besides increasing the number of people completing an action, such as a purchase or registration, BE insights can also be applied to reduce errors. One US study demonstrated that asking for a signature on the first page of an application form (instead of the end) improved the accuracy and honesty of submissions, including a 10% difference in the data captured in the form.19 A notable difference between these examples is that while user frustration prompted the first organisation to reconsider their website registration requirements, other insights would simply never be volunteered. People even disbelieve they would be swayed by information about their neighbours, or change their answers in a form based on its order. The beauty of behavioural perspectives is that without dismissing feedback we can also go beyond it; uncovering factors people are less aware of. 16 Luke Wroblewski, Web Form Design: Filling in the Blanks (2008) The Behavioural Insights Unit was commissioned soon after David Cameron’s team read: Richard Thaler, Nudge: Improving Decisions About Health, Wealth, and Happiness (2008) 18 http://www.cabinetoffice.gov.uk/sites/default/files/resources/Behaviour-Change-Insight-Team-AnnualUpdate.pdf 19 Shu et al. When to sign on the dotted line? HBS Working Paper (2011) 17 ©Copyright PrimeDecision 2012 Application #5 Stresses and shortcuts If behavioural economics had a mantra, ‘stresses and shortcuts’ might be it. Let’s return to the starting point: our energy-efficient brains hardwired to seek out paths of least resistance. Barriers like the presence of uncertainty or too much information drive people to procrastination and existing habits. So marketers should be ruthless in identifying and removing potential causes of mental stress at customer and prospect touch-points. They may seem minor when viewed with awareness, but can have a surprising impact on behaviour. When taking a behaviour-led approach for the first time, it makes sense to identify a single behaviour that you wish to change. Be conscious not to choose a general objective, like to increase sales. Select a decision that takes place in a specific context. The more control you have over the context, whether it’s a website, physical building or phone app, the more potential levers will be available to pull. Some examples of behavioural goals: Increase the number of people who add a charitable donation during their online purchase transaction, while raising the average donation value. Get more people to contact an advice line in response to a direct mailer. Increase the number of students who use the kitchen recycling bins in university halls of residence. A focused and measurable initiative will help build the business case for future activity. But it’s also a useful way to build internal familiarity with the concept. If an organisation routinely tackles a problem in a certain way – for instance, throwing greater volumes of data at a campaign, rather than working to enhancing response rates – then the opportunity to apply BE may not be immediately apparent. ©Copyright PrimeDecision 2012 The Seven Lenses Once you have defined a desired behaviour change, analysis can begin. The Seven Lenses is a proprietary framework that PrimeDecision developed for this purpose. Each lens analyses a different facet of behaviour through a cluster of related heuristics and decision-making tendencies. Rather than delivering ‘audience insights’ in a vacuum, analysis should focus on developing hypotheses about which factors which might affect behaviour in the defined context. This will yield a series specific tactics which can then be prioritised and tested. Story Social Script Sense Scenario Structure Sync Without wanting to prejudice the findings, it can be useful to set some upfront parameters, flagging the contextual factors which are clearly beyond the scope or budget of the brief. Conducting direct, observational research is highly recommended, though not always possible. Existing data, such as marketing campaign results or web analytics should also be integrated into analysis and used to help structure the roadmap. ©Copyright PrimeDecision 2012 Story: Personal narrative: attitudes and views people hold consciously. How people think they act and how they explain and justify their actions. Script: Scripts are unspoken sets of expectations which guide how people respond in different types of context, influencing conduct, interactions and even subsequent memories of events. It can make sense to either mirror or disrupt them. Sense: This lens combines environmental aspects – sounds, visual stimuli etc. – with perception and response. What is noticed and experienced and what impact this has. Social: This lens considers other humans in the context as well as signs, language and other signifiers which induce tribal or social responses. Structure: Layout and design, but also the choice architecture and options presented. These factors impact many aspects of automatic and cognitive decision-making. Scenario: Exploring variables and temporary circumstances that lead to different outcomes: they can be short-term or long-term, internal or external. Sync: This ‘wildcard’ lens considers alternative contexts and parallels. Understanding why people adopt contradictory behaviour can also be illuminating. ©Copyright PrimeDecision 2012 Scenarios: application examples While this table cannot reflect the depth of a full analysis, it should provide an introduction to how the lenses translate to both offline and online contexts. Story Script Social Sense Structure Scenario Sync Target behaviour: Target behaviour: Increase the number of people who add a charitable donation during their online purchase transaction, while also raising the average donation value. Increase the number of students using the kitchen recycling bins in university halls of residence. User objection to the brand seeking to build its own reputation by asking its customers to donate. Tackle this perception by direct, clear reasoning and use of disarming tone. Recycling perceived as ‘nice to have’, aligned with freshers’ fair, clubs etc. Explore using commitment devices (e.g. rotas) to strengthen and formalise intention, combining with official processes like signing rent agreement. Ingrained habits associated with the kitchen. Change door sign from ‘Kitchen’ to ‘Kitchen and Recycling Centre’ as part of initiative to disrupt existing script and create new patterns in the space. During purchase process, users adopt a script associated with EasyJet, ‘Running the gauntlet’. This makes donation less likely, as involves fast, concentrated scanning, optingout and avoiding upsell. Potential to disrupt by priming the donation earlier or signalling purchase completion before asking. Potential to establish donation norms through messaging – e.g. by stating what ‘customers have raised/achieved to date’. Test value of specific messaging variants, such as impact of donations in a particular geography. Donation not visually distinct from items like terms and conditions. Test the impact of section boxing, colour and emotive imagery. Distinct ‘chunking’ of the purchase process may also trigger a refresh in cognitive load. Experiment with donation framing: by changing the default donation amount, by using scaled options with different values, by using different anchor amounts etc. Analyse the impact of purchase amount, geo, product type and repeat custom on donation behaviour – e.g. potentially aligning donation value to spend via a tailored pages. Scope to incorporate donations into postbooking and offline product experiences. Offering a donation incentive/thank you which increases customer exposure to other product lines could enhance cross-sell which triggering reciprocation value. ©Copyright PrimeDecision 2012 Use social approval indicators like smiley faces on bin stickers: e.g. ‘Thanks for recycling ’ or ‘Going to landfill Have you recycled all you can?'. Replace black liners with clear bin bags to improve awareness of what is being thrown out. Bin positioning: ensure that recycling bins are physically positioned before landfill bins at major entrances, making them slightly easier to reach. Build seasonal and term-specific factors into comms plan: importance of fresher habits, mid-term reinforcement, staggered recycling messages – e.g. cans, glass & paper are most familiar, food bins tend to smell in summer. Question policy that students empty recycling bins yet cleaners empty landfill bins. This is an incentive not to recycle. Many students have never emptied a bin before, so may associate recycling with gaining additional (unpleasant) new duties. The above examples raise two related issues: Firstly, there is a myth that BE insights must always be counterintuitive and left-field, however its approaches often work because they leverage what’s familiar, such as existing tendencies or habits. Secondly, it’s quite conceivable that several of the listed tactics could be identified by marketers drawing on past experience rather than psychological insights and scientific studies. BE doesn’t claim exclusivity, it simply brings new tools and terminology with which to enhance our existing capabilities. It’s also worth underscoring that BE provides organisations with a fresh impetus to question factors of communications that are otherwise overlooked – and this brings tremendous value in its own right. A process of analysis, using tools like the Seven Lenses, should lead to the development of an experimentation roadmap which prioritises the factors to be tested and defines the timescales and metrics in detail. The cost and ease of trialling different variables should be balanced against the body of evidence for a particular approach. Staying informed of recent studies in the academic sphere is beneficial for this purpose. Supplementary research and micro-experiments may help to build the case for more involved trials, whereas other approaches (such as website changes) may be so easy to test that they require minimal justification. The roadmap structure should enable the organisation to start with broad strokes, finding areas for uplift, but also provide an ample opportunity to hone the details. For example, you may find through an initial round of trials that using scales of different donation amounts are proving more effective than a straight-forward opt-in/opt-out mechanic. A second round of tests would then be required to refine the specific values on the scale which influence people to donate a greater amount. There will often be scope to scale the approach too, transferring the learning to other marketing or fundraising activities which leverage a similar mechanic. Incorporating activity reviews into your roadmap will support this process. ©Copyright PrimeDecision 2012 Pitfalls to avoid #6 The behavioural sciences inform marketers’ decisions about what to do differently in order to improve effectiveness. But they also compel us to use sound methods of experimentation. For in spite of the best intentions, testing can be undermined by poor execution. One tendency to watch for is confirmation bias, in which we seek out evidence which supports our own beliefs or views. It can be tempting to draw premature conclusions when the results indicate that an initiative is ‘working’ in line with our hypothesis. We might also falsely attribute results to our efforts, despite them being affected by other factors. Running too limited a test can lead to deceptive results which trip us up in the long term. Equally, we may find that the first test yields no difference in response rate, or perhaps even reduces the number of responses. Again, we must fight the urge to pull the plug early; for it doesn’t mean that the process is at fault, it just means that the variables being tested are not the right ones to create uplift. Internal initiatives in particular can be prone to the Hawthorne effect.20 The term relates to a series of experiments conducted in a factory in the 1920s, which intended to study the impact of light intensity on worker productivity. Taking employees out of their usual environment and monitoring them in a separate room succeeded in generating an improvement in productivity, though the outcome was attributed to the social aspects of the experiment rather than the changes in lighting which they had set out to investigate. Although a spurt in productivity might be welcomed by a marketing department, we should be keenly aware of the impact that initiatives have on the productivity of the people involved. It is plausible that providing training in BE principles to a field sales team, for instance, could produce an improvement in sales on account of the attention and the enthusiasm it provokes, rather than the value of the training itself. 20 http://en.wikipedia.org/wiki/Hawthorne_effect ©Copyright PrimeDecision 2012 One of the biggest mistakes to make when experimenting is to test an insufficient sample size. A lovely example of flawed conclusions drawn from limited datasets: Consider this: A study of the incidence of kidney cancer in the 3,141 counties of the United States reveals a remarkable pattern. The counties in which the incidence of kidney cancer is lowest are mostly rural, sparsely populated, and located in traditionally Republican states in the Midwest, the South, and the West. Now, what do you make of this information?21 As marketers, it’s hard to hold back from devising a fascinating pen portrait of the people in these rural communities, perhaps supposing that factors like country air and a lack of pollution could be responsible for healthier kidneys. The reality is that the statistic is coincidental. These counties have small populations in common and the small sample size leads skews the results. The same counties tend to exhibit the highest incidences of other types of cancer, whereas counties with big populations come out with more reliable averages. Humans are adept hypothesisers, brilliant at spotting patterns and drawing conclusions. But we must fight this tendency if we are to draw accurate conclusions and generate the marketing ROI improvements we seek. 21 Howard Wainer and Harris Zwerling data, cited in The Week: http://theweek.com/article/index/224043/thedangers-of-quick-thinking ©Copyright PrimeDecision 2012 Conclusion: Creativity #7 This paper has focused on the role of BE in refining interactions on a very tactical level – to optimise response rates, for example. But the potential for innovation goes far beyond this. For much of marketing’s history, creativity was perceived as the domain of the artist. Big ideas meant catchy headlines and memorable imagery, with measureable results a pleasant bonus. But as new platforms, mediums and data-centric marketing took hold, the emphasis shifted. Ability to measure and analyse brought a newfound accountability. Marketing departments could better quantify their contribution to the business, yet this brought tremendous pressure to deliver. In our era of efficiency, where almost every marketing decision requires a supporting data-point, it can be hard to think differently and justify investment in new ideas. Organisations can find themselves locked into what has worked historically, at best missing out on opportunities for growth, and at worst losing ground in an increasingly competitive and uncertain marketplace. In this challenging context, we desperately require creativity and resourcefulness. In BE, we have a creative approach that’s rooted in science and lateral thinking – and highly befitting of our age. Just as human behaviour is bound in habits and routine, so are organisations influenced by legacy beliefs and practices. By stripping everything back and analysing how human beings make decisions in a world of possibilities, we can shed new light on old challenges. Behavioural economics helps us to deepen our understanding of human experience. It invites us to step outside of established categories like copy, imagery and product benefits, noticing how labels like buyer, audience and product bias our thinking. With more awareness of the automatic aspects of behaviour we can re-examine how people make choices to engage, buy and use – and find smarter solutions. ©Copyright PrimeDecision 2012 About us PrimeDecision is an independent strategy company specialising in behavioural economics.
