Introduction to Kristen Berman

Kristen Berman, a behavioral economics expert and co-founder of Irrational Labs alongside renowned professor Dan Ariely, joins hosts Eli Woolery and Aaron Walter to delve into the intricacies of integrating behavioral science into product design. Kristen shares her journey from working as a product manager at Intuit to collaborating with Dan Ariely and leading Google's behavioral economics group.

Kristen Berman [04:19]: "We worked with over 25 teams from self-driving cars to YouTube to AdWords. The team still exists there and so that's exciting."

Understanding Behavioral Economics

Kristen defines behavioral economics as the study of how cognitive, emotional, and social factors influence our decisions, often leading us to act irrationally. She emphasizes that environmental design can significantly impact behavior more than individual attitudes or beliefs.

Kristen Berman [05:46]: "Behavioral economics, and I sometimes say behavioral science, basically studies these behaviors... how we make decisions."

She illustrates this concept with everyday examples, such as the temptation of M&Ms, highlighting how the placement and accessibility of items can dictate our actions more than our conscious preferences.

Kristen Berman [06:53]: "If you move them farther away from me, I eat less of them. If you cover the jar, I eat less of them."

Behavioral Design in Product Development

Kristen discusses the application of behavioral economics in designing products that facilitate desired user behaviors. She underscores the importance of making actions easy for users, thereby reducing cognitive and logistical friction.

Kristen Berman [09:59]: "There are a lot of forces acting on us every minute... It's easy to do or it's hard to do."

She highlights that successful products often start by making existing tasks easier before attempting to change user behavior. For instance, Amazon simplified online ordering with one-click purchases, and Uber made hailing a taxi more convenient.

Kristen Berman [12:18]: "The innovation was making something somebody was already doing easier."

Case Studies: Chime and One Medical

Chime:

Chime, a challenger bank, exemplifies effective behavioral design by offering immediate, tangible benefits that motivate users to switch from traditional banks. Initially focusing on eliminating overdraft fees, Chime later introduced early paycheck deposits, providing a compelling reason for users to adopt their services despite inherent inertia.

Kristen Berman [13:48]: "The benefit has to be so motivating that they're prioritizing that over... get paid two days earlier."

One Medical:

One Medical faced challenges in user engagement despite offering free benefits through employers. Through a "behavioral diagnosis," Kristen's team identified that users lacked a clear mental model of One Medical's services and were overwhelmed by excessive choices of doctors. By simplifying onboarding and limiting choices, they increased appointment bookings by 20%.

Kristen Berman [18:17]: "We provided you with providers, we offer doctors and then limit the choice. And by doing this, we increase bookings by 20%."

Ethics of Behavioral Design

The conversation shifts to the ethical considerations in behavioral design, particularly the potential for creating addictive products. Kristen stresses that ethical design is governed by the incentives companies set for their designers and product managers.

Kristen Berman [20:45]: "We focus on the behavior. What is the behavior that you want someone to do? And more often than not, the behavior is actually aligned with the user intent."

She cites the example of Juul, which intended to reduce smoking-related health risks but inadvertently increased nicotine addiction among teenagers. Kristen argues that companies must engage in moral debates to navigate such ethical dilemmas and implement design principles that prioritize user well-being.

Kristen Berman [24:10]: "Are you saving lives? Like, what is one life worth versus a teen addicted to nicotine?"

Overcoming Skepticism in Teams

Aaron Walter raises the challenge of convincing teams, especially those focused solely on analytics, about the value of qualitative behavioral research. Kristen responds by aligning behavioral goals with user intent, emphasizing that understanding and influencing behavior is central to product success.

Kristen Berman [24:47]: "If you're going into headspace, you want to meditate. And so the idea then is not that people understand your product, but it's that they're actually doing something differently."

She highlights the importance of focusing on specific user actions rather than generic metrics, ensuring that behavioral strategies directly contribute to meaningful user engagement.

Conclusion

Kristen Berman's insights underscore the profound impact of behavioral economics on product design. By understanding and leveraging the psychological factors that drive user behavior, designers can create products that not only meet business objectives but also align with user intentions and ethical standards. The episode offers valuable strategies for integrating behavioral science into the creative process, fostering products that are both innovative and user-centric.
