The Behavioral Science Behind Paying Your Debts

My brother and I have very different attitudes when it comes to money. 

I, for one, have ingrained savings habits, with a very structured routine at the beginning of each month where I make sure all of my obligations are paid. I keep a close eye on my balances, hardly ever carry credit card debt, and am always far from reaching my credit limit. 

My brother, on the other hand, has a somewhat different mindset. He’s very optimistic about his future income and has no issue with paying penalties on his unpaid monthly credit card balance. He is happy without reminders of payment dates and doesn’t feel the need for a structured routine or a spreadsheet to keep track of his financial obligations. 

I have always wondered why my brother and I have such different approaches toward our finances. After all, we had the same upbringing: we were born just 18 months apart, raised under the same roof, and even attended the same schools up until adulthood. Even now, we both live what one would consider generally “responsible” lifestyles: we take care of our kids, work hard, try to eat right, and have very similar workout habits. So… why does only one of us have a responsible relationship with money, while the other not-so-much? 


Through research recently conducted here at TDL about the factors impacting credit attitudes, we learned that personality traits have a significant influence on our debt repayment behaviors. By understanding these traits, we can predict attitudes toward money and create targeted interventions that promote responsible borrowing practices.

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.
