Summary:Getting users to make a small commitment and follow up on it can increase engagement with content.
When the last of the New Year's confetti settles,the New Year's resolutions begin.People decide they are going to be healthier,richer,wiser by starting some new,positive habit — a phenomenon known as the "fresh start effect."
This "honeymoon" phase rarely lasts,though.The gym traffic eventually slows,productivity and budgeting dwindles,and most of us return to our bad habits,despite our best efforts.But what if I told you that it is possible to influence behavior — to nudge people in the direction of sticking to their goals?
In his bookInfluence: Science and Practice,Robert Cialdini identifies six principles of influence:
In this article we discuss the last principle in this list — that of commitment and consistency.
Definition: Behavioral consistencyrefers to people's tendency to behave in a manner that matches their past decisions or behaviors.
Behavioral consistency is a judgement heuristic to which we default in order to ease decision making: it is easier to make one decision,and stay consistent to it,than it is to make a new decision every single time we are presented with a problem.From an evolutionary standpoint,behavioral consistency also serves us well: in a social environment,unpredictable people are less likely to be liked and to thrive among others.
In Cialdini's research,he found that not only will people go out of their way to behave consistently,they will also feel positively about being consistent with their decisions,even when faced with evidence that their decisions were erroneous.
Behavioral consistency acts at both theindividualand thesociallevel.As Cialdini states,"Once we have made a choice or taken a stand,we will encounter personal and interpersonal pressures to behave consistently with that commitment.Those pressures will cause us to respond in ways that justify our earlier decision."
Let's say you make a New Year's resolution to go to the gym three times a week at 6:00 am.Once you have made that decision,you will feel compelled to stick with it.This is the individual level — the pressure to keep a promise made to oneself. This pressure will be even stronger at the social level — that is,if the promise is public and involves others: if you and a friend both agree to meet at the gym in the mornings,you will feel more committed to your resolution and more likely to follow through. While inconsistency with ourselves might result in some guilt,inconsistency with others results in interpersonal risks.Inconsistency is seen as an undesirable trait and is associated with irrationality,deceit,and even incompetence;it can generate reactions of disappointment,anger,and confusion.These risks create tremendous social pressure to remain consistent.Thus,people will strive to ensure that their behavior matches past decisions in order to avoid undue stress.
Because of these personal and social pressures,if you make people commit to something,it's likely that they will try to follow through.The commitment does not have to be a large one.In fact,it's often a small decision.In the case of our fitness resolution,it could easily have been an off-hand,seemingly inconsequential comment made over a glass of New Year's Eve champagne.Or,in the case of my parents,it was a dismissive response to my pleas for a dog.My father would reply,"Maybe when you're older" in hopes I would forget.I nagged further,"How much older?," and eventually my mother caved and said,"Maybe when you're ten years old." Every year thereafter I counted down the years remaining until they owed me a dog.
They kept true to their word,and,much to their chagrin,when I turned ten years old,I was the proud owner of a spaniel named Toby.He lived for 11 incredible years.And in a hilarious (but predictable) turn of events,my parents loved him.
Examples of Commitment & Consistency in 万博官网manbetx下载UX
To take advantage of behavioral consistency,get your users to make an initial commitment to an activity you want them to engage in.The initial commitment you propose to the user has to be:
- Easy to make
Let's look at the workflow of writing a review for Yelp.com.Because people can start writing a review without an account,this process seems both low-stakes (no personal data is shared with the organization) and easy (no work is required to create an account before reviewing,and the interaction to rate a business and to review requires only one click).But as soon as the user begins typing the review,the form field presents motivationalmicrocopy:Keep those fingers rolling,you wizard of words.What seems like inconsequential text is actually an expert use of behavioral consistency: it reminds the user to stick to the commitment of writing a review and encourages her to make the additional commitment of writing even more.
Once people have finished their review,they are asked to commit (again) even more by creating an account.In fact,the review won't be saved and posted unless they do so.This sequence of actions takes advantage of users' previous commitment to post the review and of their aversion to data loss ("Well,I've already done all this work,I might as well sign up and not lose it.").
Finally,once the review is posted,an invitation to write another one is displayed (That was fun.Let's write another).The wording reminds users that a) they just wrote a review,and b) they can be consistent with their behavior and write more reviews for other businesses.
When the Fitbit mobile app is first launched,it asks users to state their fitness goals.This task does not involve disclosing a lot of private information and is relatively effortless,since Fitbit's target audience is made of people interested in tracking their health-related habits.Once these goals have been entered,they act as a commitment and are displayed on the user's dashboard,together with the user's progress toward the goals.This visual representation (combined with push notifications) serves as a reminder of the user's commitment to these goals and makes it more likely that they will be accomplished.Moreover,the commitment can be made public to a group of friends or health enthusiasts,thus allowing users to raise personal promises to a social level.
23andMe,a service which tests DNA to reveal genetic ancestry and health insights,uses the principle of commitment to encourage visitors to participate in questionnaires that gather data for its ongoing genetic research.23andMe first presents users a short preliminary health survey pertaining directly to their personal genetic report.This short survey is low-effort and low-stakes: it requires only a few minutes and is part of the service the user is paying for in the first place.Once this short mandatory survey is complete,the system shows the user how many questions she's answered as an initial milestone.Then it provides the option to answer more survey questions by showing a link labeledContinue answering— to give people the opportunity of keeping their commitment by providing even more data.
A progress bar indicates how many questions are unanswered.And the desktop site uses social proof to further motivate respondents by showing where they rank compared to other 23andMe participants.If you're as competitive as I am,you can reach 357 questions and still be disappointed that 29% of the 23andMe participants answered more questions than you.
Implications for 万博官网manbetx下载UX Practitioners & Stakeholders
Many mobile and websites apps require users tocreate an account before using the site.Often,this request backfires and does not create the effect the manbetx官方网站手机版designers (or stakeholders) intended.Even when this commitment is easy to make (thanks to social media and Google integrations),it is not a low-stakes interaction — personal information andaccidental commitment to long-term relationshipsare at stake.It takes time to build a relationship ofexperiential trustbefore a user feels comfortable sharing personal information.
Effectively facilitating and taking advantage of behavioral consistency is not just a matter of witty microcopy (though that can help) — it is a matter of interaction manbetx官方网站手机版design.It requires 万博官网manbetx下载UX practitioners to have a good understanding of commitment levels,prospect theory& loss aversion.It begs the analysis of the decision architecture of each workflow.In particular,here are some questions that practitioners must answer in order to reveal how much cognitive load,cost,and trust is required for each decision point in the interaction,from start to finish.
- How many choices does the user have to make at each step?
- How much information does the user need to make that decision?
- What are the default choices?
- What is theinteraction costand sometimes the monetary cost of that decision?
It also requires stakeholders and executives to reassess current customer-acquisition strategies,and maybe even business models to understand what a low-stakes decision means at various stages in the user journey.Organizations need to consider the level of trust that the user is at: at the beginning of a relationship,when trust has not yet been established,even a small request such as entering an email address can be perceived as high-stakes,but as the trust in the organization increases,high-stakes demands can become minor.
Another factor that affects what low-stakes means is theperceived valueof the organization's offerings.A company with astrong brandand clear offerings can afford imposing some higher-stakes commitments to their users even at the beginning of the relationship.
As you're manbetx官方网站手机版designing the interaction flow,remember to offer to users commitments that match their trust in your organization and their perceived value of your products or services.And focus on minimizing the interaction cost associated with these commitments: even an inconsequential request is likely to be rejected if it requires a lot of work.
Commitment and consistency are powerful motivators to increase engagement and persuade users to fulfill their goals.manbetx官方网站手机版Designs which allow users to make a small,low-cost commitment will be more likely to convert customers than ones that make commitment a costly process.An all-or-nothing manbetx官方网站手机版design will deliver nothing from most users.There are many questions that need to be answered to ensure we meet user needs at every step of the decision-making process,but it all boils down to facilitating the trust of our users,and increasing the usability and the perceived value of our products and services.
