Letting Down Our Guard With Web Privacy
Alessandro Acquisti, a behavioral economist at Carnegie Mellon University in Pittsburgh, studies how we make these choices. In a series of provocative experiments, he has shown that despite how much we say we value our privacy — and we do, again and again — we tend to act inconsistently.
Mr. Acquisti is something of a pioneer in this emerging field of research. His experiments can take time. The last one, revealing how Facebook users had tightened their privacy settings, took seven years. They can also be imaginative: he has been known to dispatch graduate students to a suburban mall in the name of science. And they are often unsettling: A 2011 study showed that it was possible to deduce portions of a person’s Social Security number from nothing but a photograph posted online. He is now studying how online social networks can enable employers to illegally discriminate in hiring.
Mr. Acquisti, 40, sees himself not as a nag, but as an observer holding up a mirror to the flaws we cannot always see ourselves. “Should people be worried? I don’t know,” he said with a shrug in his office at Carnegie Mellon. “My role is not telling people what to do. My role is showing why we do certain things and what may be certain consequences. Everyone will have to decide for themselves.”
Those who follow his work say it has important policy implications as regulators in Washington, Brussels and elsewhere scrutinize the ways that companies leverage the personal data they collect from users. The Federal Trade Commission last year settled with Facebook, resolving charges that it had deceived users with changes to its privacy settings. State regulators recently fined Google for harvesting e-mails and passwords of unsuspecting users during its Street View mapping project. Last year, the White House proposed a privacy bill of rights to give consumers greater control over how their personal data is used.
Mr. Acquisti has been at the forefront, testifying in Congress and conferring with the F.T.C. David C. Vladeck, who until recently headed the agency’s Bureau of Consumer Protection, said Mr. Acquisti’s research on facial recognition spurred the commission to issue a report on the subject last year. “No question it’s been influential,” Mr. Vladeck said of Mr. Acquisti’s work.
Companies, too, are interested; Microsoft Research and Google have offered Mr. Acquisti research fellowships. Over all, his research argues that when it comes to privacy, policy makers should carefully consider how people actually behave. We don’t always act in our own best interest, his research suggests. We can be easily manipulated by how we are asked for information. Even something as simple as a playfully designed site can nudge us to reveal more of ourselves than a serious-looking one.
