Ben Franklin Effect

Customer relationships are built through positive experiences and excellent service. The intuition suggests that those who give generously should receive generously in return. Yet some companies report the opposite: customers who receive exceptionally high levels of accommodation appear less loyal than those who take initiative themselves. The question is: Can asking for a small favor actually strengthen the relationship rather than weaken it—and what does the evidence show?

Studies

The Gain-Loss Experiment

Jon Jecker and David Landy conducted a clever experiment at Stanford University in 1969. Eighty students participated in a quiz where they could win money. After the quiz, participants were divided into three groups: One-third was personally asked by the experimenter to return the money they had won because his research funds were running low. Another third was contacted by the secretary with an impersonal request to return the money. The final third was allowed to keep their winnings. One week later, all participants rated the experimenter. The surprising result: The group that was personally asked for the favor by the experimenter rated him as significantly more likeable than both other groups—even though they had to give up their money. The personal request generated not anger, but sympathy.

Helping and Liking in the Laboratory

In 1958, Morton Deutsch at New York University investigated the relationship between helping and liking under controlled conditions. Ninety-six participants were asked to help a fellow student with a time-consuming task—either for payment, out of obligation, or on a voluntary basis. After providing help, all participants rated how much they liked the person they had helped. The unpaid voluntary helpers showed the highest liking for the person they supported—significantly higher than the paid helpers. The fascinating part: those who were paid for their help justified their behavior with the money. Those who helped without external reason had to find an internal explanation—and developed genuine liking. Liking scores among voluntary helpers were 40% higher than among paid helpers.

Principle

Which principle for Customer Experience Design can be derived from this? The Benjamin Franklin Effect demonstrates that companies can build stronger emotional bonds with customers through skillful small requests than through expensive gifts or discounts. When customers actively contribute to a brand—whether through reviews, feedback, or small actions—they subsequently develop a more positive attitude toward the company to justify their own behavior. The crucial factor is that the request must be fulfilled voluntarily and without direct compensation, as only then can the internal justification "I like this brand" take effect. However, if requests are too large or intrusive, the effect reverses and can lead to resistance. The following guidelines show how to implement this principle in practice.

Guidelines

Request feedback or reviews

Request feedback, reviews, and suggestions from customers—not just after purchase, but throughout the development process. When people share their knowledge or opinions, they become emotionally invested and develop stronger attachment to your brand. Critical caveat: Your request must be genuine, and you must visibly act on the feedback. A follow-up message like "Thank you for your suggestion—we've implemented X" significantly amplifies this effect.

Request minor assistance

Strategically integrate small, voluntary requests for assistance throughout the customer journey. Examples include: "Would you help us by sharing this article with a friend who might benefit from it?", "Could you briefly indicate which of these features are most important to you?", or "Do you have 30 seconds to tell us why you chose us?" These micro-investments create commitment and goodwill—provided there is no reward or obligation attached.

Creating Co-Creation Opportunities

Invite customers to actively participate in product development, campaign design, or community building. Beta testing programs, customer advisory boards, and "vote for the next feature" initiatives serve as both valuable information sources and powerful loyalty-building tools. When participants invest their time and expertise, they justify this investment by deepening their commitment to your brand. Critical caveat: Participation must be voluntary and carry genuine influence—otherwise, the effect backfires.

Ask for referral before incentive

Structure referral programs so that the request comes BEFORE the reward. Instead of "Refer us and receive $20," try: "Would you recommend us to a friend? If so, we'd like to thank you with a small token of appreciation." The intrinsic motivation behind the initial recommendation creates stronger commitment than an action driven immediately by monetary incentives. When people refer others without an upfront reward, they justify their behavior through genuine conviction.

Asking for recommendations

Asking satisfied customers for referrals is not just about acquisition – it strengthens their own loyalty. Those who recommend someone want to be proven right and remain customers themselves. The following examples illustrate this guideline:

• Dropbox: 'Invite a friend and get more storage' – The referral is a favor. The referrer becomes more loyal themselves.
• Tesla: The referral program turns customers into salespeople. Those who recommend Tesla become even bigger fans themselves – the Ben Franklin Effect in action.

Set up feedback channels

Establish structured feedback channels and actively involve customers in decision-making processes through voting systems, co-creation initiatives, or direct requests for their opinions. The simple act of asking for feedback transforms customers into co-creators and strengthens their loyalty. Communicate transparently about how their input is being used. The following examples illustrate this guideline:

• UserVoice/Canny: Product feedback tools that show: 'This feature was requested by customers and has now been implemented.' Closing the loop amplifies the voice effect.
• Slack: Public roadmap and 'What's New' announcements that explicitly reference customer feedback: 'You asked, we delivered.'

Participate in development

Actively involve customers in product development through beta tests, feedback sessions, or advisory boards. This involvement transforms consumers into partners and, via the Hawthorne effect, converts them into your most loyal advocates. Early adopters and power users, in particular, become invaluable champions of your product. The following examples illustrate this guideline:

• Notion: Notion Ambassadors are invited to product feedback sessions. The input is valuable – but the real effect: they feel like co-creators, not just users.
• LEGO Ideas: Fans can submit and vote on product ideas. The few that get produced are less important than the thousands who feel like part of the LEGO world.
