John Tierney offers a summary from a recent study published in Science about our ability to predict our future tastes and personality changes:
[W]hen asked to predict what their personalities and tastes would be like in 10 years, people of all ages consistently played down the potential changes ahead.
Thus, the typical 20-year-old woman’s predictions for her next decade were not nearly as radical as the typical 30-year-old woman’s recollection of how much she had changed in her 20s. This sort of discrepancy persisted among respondents all the way into their 60s.
And the discrepancy did not seem to be because of faulty memories, because the personality changes recalled by people jibed quite well with independent research charting how personality traits shift with age. People seemed to be much better at recalling their former selves than at imagining how much they would change in the future.
And another interesting bit:
When asked about their favorite band from a decade ago, respondents were typically willing to shell out $80 to attend a concert of the band today. But when they were asked about their current favorite band and how much they would be willing to spend to see the band’s concert in 10 years, the price went up to $129. Even though they realized that favorites from a decade ago like Creed or the Dixie Chicks have lost some of their luster, they apparently expect Coldplay and Rihanna to blaze on forever.
