Why so many people make this big Social Security mistake

One of the biggest mistakes people make when it comes to Social Security is claiming too early at a much lower benefit.

Americans can boost their chances of not outliving their savings by delaying taking Social Security benefits, which will increase their monthly check substantially for decades.

But even understanding that economic argument gets trumped by more powerful psychological factors, according to a new working paper published by the National Bureau of Economic Research. Instead, many people start claiming Social Security benefits as soon as they possibly can — at age 62.

"They give up money to be able to do that," Suzanne Shu, a professor of marketing at Cornell University’s Dyson School of Applied Economics and Management and one of the co-authors of the paper, told Yahoo Finance. "They front load."

Psychological explanations for early claiming

Approximately 40% of men and 47% of women claim at age 62, according to the Social Security Administration. Only 3% of men and 4% of women claim at age 70, when they get the most in benefits. Roughly 17% — averaged across men and women — claim at their full retirement age. These levels do shift slightly from year to year, but not by a lot.

While there are "clearly good personal reasons for claiming early, such as poor health or financial constraints due to no other source of retirement income, claiming earlier versus claiming later reflects significant psychological variables," said John W. Payne, the paper’s other co-author and a professor emeritus of business administration at the Fuqua School of Business at Duke University and a professor of psychology and neuroscience.

The authors’ research was conducted over the past decade and consisted of four studies with roughly 4,000 participants in total between the ages of 40 and 62, who have not claimed their benefit yet.

"We wanted to understand what people are thinking about as they're working through the trade-offs of earlier versus later claiming," Shu said.

Perhaps the biggest factor in the grab-the-money-ASAP decision is the psychological ownership of one’s Social Security benefits, according to the research.

"Many people get fixated on wanting to get the money sooner," Justin Smith, a fee-only certified financial planner with Savant Wealth Management in Phoenix, Ariz., told Yahoo Finance.

That’s exactly what Shu and Payne discovered.

The second psychological factor that results in early claiming is a feeling that if you don't live long enough, the government gets to keep some of your money.
