Scientific Freedom, False Positives and the Fountain of Youth

The Huffington Post:

“Chronological rejuvenation” is psychological jargon for the Fountain of Youth, that elusive tonic that, when we find it, will reverse the aging process. Though many of us would welcome such a discovery, most of us also know it’s a fantasy, a scientific impossibility.

So imagine my surprise when I came across this report on chronological rejuvenation while browsing in the highly regarded journal Psychological Science. I am including it verbatim, because (as you’ll see) the technical details are important:

Using the same method as in Study 1, we asked 20 University of Pennsylvania undergraduates to listen to either “When I’m Sixty-Four” by The Beatles or “Kalimba.” Then, in an ostensibly unrelated task, they indicated their birth date (mm/dd/yyyy) and their father’s age. We used father’s age to control for variation in baseline age across participants. An ANCOVA revealed the predicted effect: According to their birth dates, people were nearly a year-and-a-half younger after listening to “When I’m Sixty-Four” (adjusted M = 20.1 years) rather than to “Kalimba” (adjusted M = 21.5 years), F(1, 17) = 4.92, p = .040.
