The perils of persuasion
7 April 10
On graduation, I found the business world laughable. I saw otherwise intelligent people wrapped up in circular rituals of ‘doing business’, oblivious to customer disinterest. My cynicism lasted until I discovered user-centred design and realised there were others who shared my viewpoint. From that point, I saw user experience as a refreshing break from the almost Fordist attitudes I’d witnessed, where business tried to create the market and efficient production appeared more important than demand.
My mindset was naive, but I stand by the principle. One of the things that excites me about UCD is that it isn’t only a mode of design: its values amplify the voice of those previously ignored, who now form part of our network economy.
The success of UCD has sustained demand for user experience design skills, and the land rush has continued in 2010. UX is becoming a cookie cutter add-on for digital agencies and I rarely meet a web designer now who doesn’t claim UX proficiency, although not all can articulate what that means. And it’s not just the designers: I also see back-end developers, SEO professionals and marketers rapidly appending these two magical letters to their CVs.
Many of these people do have genuine user empathy and knowledge of the diverse skills required of UX design. Many do not. I welcome them to the field regardless and hope we can all learn from each other. However, I am concerned at the expansion of the User Experience label to include activities I see as contrary to the values of user empowerment. In particular, I’m worried about persuasion design. Although it’s a powerful and topical approach, I also believe it has the potential to severely damage our industry.
A political model of design
Interaction designers often advocate design as an agent of behaviour change. Jesse James Garrett frames this as an extension of the classic information architecture v interaction design debate, with IA optimising for the way people think, and IxD attempting to drive particular user actions.
When I try to make sense of this struggle, the crude model I keep returning to is a political spectrum. User-centred design, empathetic and inclusive, sits left of centre. Persuasion design, individualised and competitive, sits right of centre.

As with politics, one’s stance is a matter of preference and most mainstream modes are appropriate. The problems lie in the extremes: let’s call them radical UCD and radical persuasion design.
Radical UCD
Under radical UCD, the user’s priorities outweigh others. It’s here that we see Naoto Fukasawa‘s notion of design ‘dissolving into behaviour’ realised. Design becomes an ethically neutral activity whose role is to amplify and liberate the end user. The rewards are intangible, long-term and altruistic: we hope to engender loyalty and word of mouth referrals, but the effects are notoriously hard to measure.
However, as with the political equivalent, radical UCD is economically unrealistic and unworkable. At this extreme, design could only cause consensus-building timidity that reinforces current modes – an accusation already pointed at milder contemporary user-centred practice.
Radical persuasion design
Persuasion design doesn’t share UCD’s ethical neutrality. Instead, it makes an implicit but undeniable judgment that certain behaviours are preferable to others. We need only look at the vocabulary of persuasion design to see this. Jon Kolko’s infamous Johnny Holland article talks of design’s contribution “to the behaviour of the masses, [helping to] define the culture of our society.”
While I respect Jon’s intellect, I find this to be dangerous rhetoric from which we can draw uncomfortable parody: Fear not, huddled masses – the design elite will lead you to the promised land. Persuasion design’s assured ethical superiority is unfortunate. Although some of the cases put forward are compelling – guiding people toward better macroscopic decisions about environment, health etc – we must recognise that, for all the good deeds behaviour change can encourage, it is prone to murkier applications.
What privileges the designer to dictate desired behaviour? And since we’re for hire, does that mean we’re ethical relativists, bending people toward whatever agenda lines our pockets?
Whomever the paymaster, the common pattern I observe in digital persuasion design is that its values are uniformly technocratic. Science is better than faith. Action is better than reflection. Progress is better than the status quo. These values strike me as practically Futurist and, at the risk of invoking Godwin’s Law, I’m concerned that radical persuasion design is vulnerable to similar autocratic pitfalls.
Persuasion design is marketing. UX isn’t.
I have struggled for months to unify my understanding of these two political wings, and now conclude that I cannot. I believe that persuasion design is not part of user experience design. It is marketing. Persuasion design prioritises business goals above those of the user, and its values are irreconcilable with empathy, the central value of UX.
That’s not to say that persuasion design isn’t highly valuable and attractive to business. After all, it matches the recognised business patterns of marketing, making its effects felt in tangible measures that UCD’s intangible altruism cannot: conversion rates, signups, and so on.
I subscribe to Peter Drucker‘s view that business has only two functions: innovation and marketing. Under this model, user experience design is innovation. It uncovers people’s needs and and gives makers the knowledge to develop new products and services that meet those needs.
This, finally, is why I disagree with Josh Porter’s assertion that UX is really just good marketing – however, my disagreement isn’t with his framing of marketing, but of user experience. As far as persuasion design is concerned, he is right – but the equation does not apply to UCD and UX.
Opinions and unwinnable arguments
I am of course straying close to two notoriously unwinnable arguments: semantics and politics. I have neither time nor inclination to enter into political debate or vanish down the rabbithole of Defining The Damn Thing, and I am all too aware that, like any model, the one I give is simplistic. It overlooks the complexities of authoritarianism and liberalism, which are not necessarily tied to economic left or right, and belies the greys that lie between black and white. I raise it instead as a way to highlight the risky territory I believe we are heading toward. All I ask is that the community considers these issues carefully and reaches its own conclusions. I’m happy if those differ from mine.
Even if my thoughts turn out to be at odds with those of the broader UX community, I’ll take heart from the words of Dieter Rams, who also took a stance against the involvement of persuasive techniques:
Braun categorically rejects the idea of motivating people to buy its products by adding features that toy with the psychological sub-terrain of the consumer’s consciousness. Braun refuses to swell sales by exploiting human frailties: neither its products nor its advertising use such seduction techniques.
Those who wish to employ persuasive techniques are welcome to do so. But my focus continues to be on striving to make better products by listening, not driving behaviour change. At times I will use tactics from the persuasion design toolkit, as I do with other tools of marketing, but I will do so only when I have fully considered the ethical implications. I hope that others will do the same.

I have no idea why, but I was expecting UX to be on the right.
It may be explained by this good ole comic http://www.recombinantrecords.net/docs/2009-05-Amusing-Ourselves-to-Death.html – the minute you mention business, it all comes down to “do whatever to get profits” – which is unfortunate for our ethic standards – UX is the “whatever” these days. Deciding to call it marketing based on intent… is not an argument about semantics – it’s an argument about ethics, because the end goal is always “get profits”.
To rephrase, no true innovation in UX can happen without behavior change – the perfect UX is when there is no effort, no learning, no getting out of the habit, no thinking involved – pure happiness based on expected outcomes. That is not innovation – that is right wing conservatism.
Emphasis on something that I did not said directly: I’m not saying that any of those (UX vs marketing, left vs right) are absolute right or wrong.
Again a lovely piece Cennydd, it is very reassuring for me to see that there are people like you out there that give their work so much thought. I hope more people would do this.
But nevertheless I do think you are missing the point a bit.
The first rule of Persuasion Design is that every design is persuasive in some ways. There is no neutral way of designing something. Of course not everything is designed with explicitly applying persuasive/psychological principles, but implicitly you will always nudge users to some sort of behaviour.
Nudge, the small and handy Persuasive Design Bible, very clearly showed us that even if there is no Choice Architect at work, there will always be some kind of Choice Architecture, with preset defaults and other “designed” nudges towards certain behaviour.
So designs of UX-ers and UCD-ers will always nudge users towards some kind of behaviour. In this sense I also agree with Joshua Porter and Kathy Sierra that all UX-ers and UCD-ers are marketers, whether they realize it themselves or not.
Next to that Nudge also provides a fruitful direction of thought if it concerns politics (I was one of the blank votes last election, but no one call me right winged…). The concept of Libertarian paternalism launched by Sunstein and Thaler is about policy that gives you options while achieving society’s goals.
Finally Nudge has a very elegant way to describes behaviour that is “absolutely” worth promoting and behaviour that Choice Architects (i.e. designers) should try to discourage. I think Thaler and Sunstein subtly evoke alligned moral intuitions of their readers and that is the main reason why they didn’t yet get a call from Dieter Rams (or Cennydd Bowles). Talking ethics of an trade that is essentially about nudging behaviour is very important, and I hope more people will join us in this discussion.
This is a very thoughtful article – thanks, Cennydd. It needed to be written and I hope you get reactions from some of the people in IxD and UX that you cite.
Part of the problem is the term ‘persuasion’, I feel, since it evokes such different reactions. Petty & Cacioppo’s ‘central route’ and ‘peripheral route’ (http://en.wikipedia.org/wiki/Elaboration_likelihood_model ) explain to some extent how the persuasion traditionally seen in marketing (which is often about exploiting people’s cognitive biases) can differ from persuasion where a product or service (or speech) genuinely makes someone think and change his or her attitudes.
The line between the two is not necessarily clear, but it is perhaps where the good intentions can bleed into ‘murkier applications’ as you put it. B J Fogg (Persuasive Technology – http://captology.stanford.edu ) and most of the researchers following this course have been very clear that their work is primarily about social benefit and ethical considerations do form a part of that – the ‘golden rule’ outlined by Berdichevsky & Neuenschwander (http://doi.acm.org/10.1145/301353.301410 – behind ACM paywall) is that “the creators of a persuasive technology should never seek to persuade anyone of something they themselves would not consent to be persuaded of.”
Personally I see the best behaviour-influencing design to be where the needs of two (or more) parties align. E.g. if someone decides he/she wants to get fit, a mobile app which helps track everyday exercise, sets goals and and makes tailored suggestions at opportune moments align’s the user’s desire to get fit, with ‘society’s’ desire for a healthier population. The card slots often used to operate hotel room lighting, where the card must be present for the lights to work, help the guest avoid losing the card or forgetting where it is, while saving the hotel money by preventing the lights being left on while the guest is out – and in the process, reducing the environmental impact. There are people in the persuasive technology community who would argue that this isn’t persuasion, and perhaps it isn’t, but it’s certainly interaction design that affects user behaviour.
I think Arjan hits the nail on the head with the point that everything that is designed inevitably affects behaviour, whether that’s done consciously by the designer or not, and at both the micro-scale of individual interaction and the macro-scale of huge sociotechnical systems. This is something that theorists such as Richard Buchanan, Bruno Latour, John Law and Peter-Paul Verbeek have argued from different levels without ever once touching the concept of persuasion.
So on that basis, we (as designers) might as well try to understand what’s going on between ‘users’ and what we’ve designed (which is surely a fundamental part of IxD, UX and UCD approaches), and what factors are influencing people to act one way or another as part of the complex systems we’ve designed around them. It’s just good human factors practice. In this sense, in your diagram, I would argue that UCD’s ‘amplifies behaviour’ property is surely a subset of ‘affects behaviour’. It’s going to happen, so (to misquote Stewart Brand) we might as well get good at it – both understanding how it works, and doing it more thoughtfully.
Hi Cennydd
A few thoughts:
1. Why do we need to categorise and nail down what type of design we’re using today?
2. Design has to have a goal whether user-centred or persuasive. Typically with successful websites for businesses, the task is one of aligning the goals of the business with the goals of the users/customers. You can choose – as the designer – whether you want to be a part of helping the organisation achieve those goals. You can choose to work for or avoid working for that organisation.
3. As every good sales person knows, to persuade and influence you always have to listen first. Listening and understanding someone else’s motivations are also core skills for UXers. As a user experience designer you can’t choose whether or not you’re in the persuasion business.
4. Unless you’re the MD, you will rarely have the opportunity to ignore or forsake the commercial imperatives of your output in favour of a more “ethical” approach. At best you may be able to find a balance between the two.

Persuasion is a very interesting topic and I enjoy studying it. At the same time I can’t help feeling uneasy about its ambiguous nature. My sentiments lie with Arjan and Dan, but I can understand Cennydd’s doubts very well.
Starting point: all websites have a purpose and try to change the user in some way: be it knowledge, attitude or behavior. There is no such thing as a ‘neutral’ site – what would the use of a site be that doesn’t want to change you? It would be meaningless. Therefore persuasion is always part of the UCD equation.
What is persuasion? A simple definition could be: a set of techniques to intentionally influence the behavior of a target audience (website users or people in general), based on psychological and neurological research of how our minds actually work. In this sense, there isn’t much difference between UCD and persuasion design. But while UCD takes the viewpoint from the user, persuasion looks at it from the other side. And, while as a tool, it is neutral, its purpose depends on the intentions of those applying it. In the hands of the wrong people, it has the potential to hurt the audience for the benefit of the one doing the persuading. This is why ethics is always a big issue when discussing persuasion.
I use persuasion as a subset of UCD. Both start with knowing who your users are, what needs they have and how your site can meet those needs. But websites aren’t only about what users want. The owner has goals too. In an ideal world these interests match and everybody is happy.
Andrew Chak’s definition of Persuasion Web Design states it noble enough: ‘The arts and science of designing web sites that help users make decisions that result in desirable transactions.’ On the web, he argues, ‘we don’t sell to people, we help them to buy’.
But it doesn’t always end there. A lot of sites have the explicit purpose of making you hand over your money, possibly in exchange for something desirable and useful, but not necessarily. Using persuasive, i.e. sophisticated, ‘sneaky’ psychological techniques to make us buy things is day to day business in most parts of the world of e-commerce.
And it’s not like we’re actually thinking and choosing carefully while we browse the web – and here lies the real danger of persuasion. Cialdini and the teachings of behavioral economics are effective and popular because most of us use the ‘peripheral route’ anyway, which makes us vulnerable to cues and automated reactions. Research shows that persuasion as a marketing and selling technique works, regardless of the interests of users and buyers. And a lot of people see no problem using it.
Why do I study persuasion? Because its focus on psychological and neurological research helps me to be a better UX designer. Do I use it for the good of the users? Of course. Do I see the risks? You bet!
Persuasion is undeniable is a double-edged sword. Everyone talking about it should be aware of this.
I just want to say I think Dan hits the nail on the head when he says I do the same.
I think the problem with your left-right model is not that it’s simplistic, but that it’s backwards. Radical UCD’s “neutral ethics” aren’t neutral, it just accepts (and tacitly defends) the status quo, today’s right-wing capitalist values. Radical persuasion design rejects the status quo, and wants to change things, and your argument against it resembles Hayek’s Road to Serfdom argument, that elitist central planners can never be omniscient, it’s better to leave it up to individuals to coordinate their preferences in the free market.
So Radical UCD is really in a right-wing/libertarian position, while Radical Persuasion occupies the traditional left-wing position.
Having read Roberto Verganti’s book on Design Driven Innovation, I have to disagree – innovation is not made by user-centered approaches to design. This comes down to the idea that users/consumers may not know what could exist and what they would ideally want. Think about e.g. cell phones – not many thought about needing them before they actually were invented and on the market…
Hey Cennydd,
This is an intressting post. I don’t see both as seperate entities. For the last three years I was developer technology for older adults. 65+ at a research centre. Some may be using a keyboard for the first time, and some would be borderline technophobes.
Without some persuasion these technologies wouldn’t be used. Others wouldn’t be possible to have a neutral stance, as we would be testing an academic hypothesis on older adults which resulted in good behavior.
I would like to know your thoughts on a hypothesis question. How would you user centered design to create an exercise program for sedate adults?
Amen.
I believe most people generally don’t seek to understand the difference between order and control, but rather attempt to expand their perceived control. Especially true for people with power — including designers and managers.
The issue? Fighting the order of a system for perceived control is like fighting the tide. You might make a splash, but in the end, the tide does what it will.
// Your take on UX is spot on, by the way. Props on and thanks for the truly informative posts!:D //
Amen, couldn’t agree more. It appears that most people in business leave their ethics at home!
I think the previous commenter makes a valid point about perceived control. Excellent informative post.
