Most U.S. adults believe in romance—regardless of age, according to a new study conducted by YouGov. More than half of every age group in the nearly 3,000 people who were polled said they believed in soulmates. Overall, 25 percent of people said they did not believe soulmates were real, while 19 percent were unsure. Those who doubted the most were the youngest, with 31 percent of people 18 to 24 saying soulmates were not real.
