Developer removes controversial age-guessing software

If you have a profile on LinkedIn, it probably lists your educationand your work experience. But one thing it couldn't tell anyone was your age until recently.

A controversial browser extension called Age-Insight, which is a Google Chrome add-on, will estimate the age of a person when you visit their LinkedIn profile.

That means alongside their work experienceand education, you'llget the algorithm's best guess at how old that person is.

• LinkedIn settles classaction alleging it spams user contacts
• App scans pub patrons' faces to guess their age and gender

But along with that has come some controversy which has led the plug-in's designer to stop supporting his product.

Developer says it's a simple algorithm

Age-Insight was released earlier this month by Juan Ramirez, who built it in his spare time. He saysit came out of his own personal habit of trying to guess the ages of people he'd see on LinkedIn.

According to Ramirez, Age-Insight uses a fairly simplealgorithm, which makes a guess on a person's ageby looking at the graduation year on aLinkedIn profile.

He said it also incorporated data on things such as a person's name.

"You can pool this dataand say, like, 'Oh, this person is named Juan,' " he said. "Juanwas a popular name in 1989. You can try to normalize the data using that."

Workexperience, and the number of jobs a person has held, were also incorporated

Ten days after it was released, Age-Insight was featured on Product Hunt, aninfluential technology website, where it quickly earned a mixed reaction.

Age discrimination concerns

While some people appreciated the idea of being able to guess a LinkedIn member's age, others worried Age-Insight couldenable age discrimination.

Which is when Ramirez says he had a change of heart about his add-on.

"I didn't develop this extension to encourage that kind of behaviour," he said. "Probably by 2p.m. that day, I was ready to shut it down."

The same day the add-on was profiled on Product Hunt, Ramirez says, he receiveda cease-and-desistorder from LinkedIn.

So on Oct. 18, he removed Age-Insight from the Chrome Store, andposted a notice to his websitesaying he'd no longer support the plug-in, and thathedidn't want to be seen as enabling discrimination of any kind.

But that doesn't mean Age-Insight is necessarily gone likeso many things online, once this kind of software has been made public, it's hard to take back.

This is also not the only age-identifying software we've seen recently. Earlierthis year, Microsoft created an online tool called How-Old.net, which would guess the gender and age of a person based on an uploaded photo.

While both How-Old.net and Age-Insight were replicating things humans might naturallydo guess a person's age based on available information the difference is thatthe process has been automated, whichcould lead to unintended consequences.

And Ramirez said his experience with Age-Insight offers a caution: Just because you can solve a technical challenge, doesn't mean you should.
