What Facebook Knows About You Is Scary!

facebook-global

If Facebook were a country, a conceit that founder Mark Zuckerberg has entertained in public, its 900 million members would make it the third largest in the world… It would far outstrip any regime past or present in how intimately it
records the lives of its citizens.

Private conversations, family photos,
and records of road trips, births, marriages, and deaths all stream
into the company’s servers and lodge there. Facebook has collected the
most extensive data set ever assembled on human social behavior.

Some of
your personal information is probably part of it.

And yet, even as Facebook has embedded itself into modern life, it
hasn’t actually done that much with what it knows about us.

Now that the
company has gone public, the pressure to develop new sources of profit (see “The Facebook Fallacy)
is likely to force it to do more with its hoard of information.

That
stash of data looms like an oversize shadow over what today is a modest
online advertising business, worrying privacy-conscious Web users (see “Few Privacy Regulations Inhibit Facebook”)
and rivals such as Google.

Everyone has a feeling that this
unprecedented resource will yield something big, but nobody knows quite
what.

Even as Facebook has embedded itself into modern life, it hasn’t
done that much with what it knows about us. Its stash of data looms like
an oversize shadow. Everyone has a feeling that this resource will
yield something big, but nobody knows quite what.

Heading Facebook’s effort to figure out what can be learned from all our data is Cameron Marlow,
a tall 35-year-old who until recently sat a few feet away from
­Zuckerberg.

The group Marlow runs has escaped the public attention that
dogs Facebook’s founders and the more headline-grabbing features of its
business. Known internally as the Data Science Team, it is a kind of
Bell Labs for the social-networking age.

The group has 12
researchers—but is expected to double in size this year. They apply
math, programming skills, and social science to mine our data for
insights that they hope will advance Facebook’s business and social
science at large.

Whereas other analysts at the company focus on
information related to specific online activities, Marlow’s team can
swim in practically the entire ocean of personal data that Facebook
maintains.

Of all the people at Facebook, perhaps even including the
company’s leaders, these researchers have the best chance of discovering
what can really be learned when so much personal information is
compiled in one place.

Facebook has all this information because it has found ingenious ways
to collect data as people socialize. Users fill out profiles with their
age, gender, and e-mail address; some people also give additional
details, such as their relationship status and mobile-phone number.

A
redesign last fall introduced profile pages in the form of time lines
that invite people to add historical information such as places they
have lived and worked.

Messages and photos shared on the site are often
tagged with a precise location, and in the last two years Facebook has
begun to track activity elsewhere on the Internet, using an addictive
invention called the “Like” button.

It appears on apps and websites outside Facebook and allows people to
indicate with a click that they are interested in a brand, product, or
piece of digital content.

Since last fall, Facebook has also been able
to collect data on users’ online lives beyond its borders automatically:
in certain apps or websites, when users listen to a song or read a news
article, the information is passed along to Facebook, even if no one
clicks “Like.”

Within the feature’s first five months, Facebook
catalogued more than five billion instances
of people listening to songs online.

Combine that kind of information
with a map of the social connections Facebook’s users make on the site,
and you have an incredibly rich record of their lives and interactions.

“This is the first time the world has seen this scale and quality of
data about human communication,” Marlow says with a characteristically
serious gaze before breaking into a smile at the thought of what he can
do with the data.

For one thing, Marlow is confident that exploring this
resource will revolutionize the scientific understanding of why people
behave as they do.

His team can also help Facebook influence our social
behavior for its own benefit and that of its advertisers. This work may
even help Facebook invent entirely new ways to make money.

Contagious Information…
