Experts say one of the barriers to saving for retirement is psychological. Overcoming that barrier could be as simple as having a young person see into the future. Researchers at New York University’s Stern School of Business used virtual reality to let college-age men and women interact with their 70-year-old selves. Study participants were later asked a series of questions about finances and retirement. Those who had seen their future self were willing to put twice as much into long-term savings accounts as those who had seen their current self.
