Buy Now, Pay Forever: How new consumer debt options influence the psychology of young people

Young people today live with debt in ways that were once inconceivable. Student loans often take decades to pay off, and high interest rates mean that auto loans are now offered at terms of 84 months or longer. Unlike the mortgages that were the motor of American middle-class wealth in the 20th century, these loans do not leave their holders with a salable asset. 

The rise of Buy Now, Pay Later (BNPL) services, which allow consumers to finance online purchases at checkout, has helped to normalize such unproductive debt. A recent survey from the behavioral data company Fullstory found that 48% of consumers in the United States use BNPL at least once per week, on product categories including electronics, clothing, and furniture.1 The age of these users skews young, but they are not exclusively Gen Z. More than a third of Gen Z, Millennial, and Gen X consumers use BNPL at least twice a week, compared to just 5% of Baby Boomers.

What is less well understood is the effect that normalized BNPL use may have on the financial psychology of the young people who use it most. Previous generations developed their intuitions about money and debt through experiences with credit cards, mortgages, and installment loans, each of which carried enough friction to make borrowing feel like a serious decision. BNPL, which is available at the point of purchase and typically interest-free for short repayment windows, may be training a generation to experience debt as something closer to a payment format than a financial commitment. That psychological shift has implications that extend well beyond the size of any individual purchase.

I was blown away with their application and translation of behavioral science into practice. They took a very complex ecosystem and created a series of interventions using an innovative mix of the latest research and creative client co-creation. I was so impressed at the final product they created, which was hugely comprehensive despite the large scope of the client being of the world's most far-reaching and best known consumer brands. I'm excited to see what we can create together in the future.

The Will, The Way, and Everything In Between

Behavioral science explains why the motivation of "where there's a will, there's a way" often fails: we get stuck when we lack a path, lack the will, or have too many paths to choose from.

The Behavioral Science of Remote Trust

This article will explore the behavioral science behind remote trust, beginning with the visibility bias that drives many return-to-office mandates. We’ll look at how monitoring and control can paradoxically reduce engagement, and walk through key behavioral models that help explain why employees often feel frustrated or disengaged under these policies.
