Consumers are more likely to gain weight when paying with credit cards, because they are more likely to buy junk food as a result, according to a new study.
A Journal of Consumer Research report written by economists Manoj Thomas, Kalpesh Kaushik Desai and Satheeshkumar Seenivasan concluded that shoppers paying with credit cards find it harder to resist indulgent purchases such as fast food or unhealthy treats.
And how does that work, exactly?
Credit cards weaken the impulse control of consumers, making it more difficult for them to rationalize that something is not a necessary purchase, according to the study.
As usual, George Carlin was a bit more direct about it: “No one should be paying the bank eighteen percent interest on Tic-Tacs.”
