Facebook Inc. told a U.S. senator that an internal investigation
had found "no evidence of systematic political bias" against
conservatives in its trending topics tool, but that it will revamp
how the feature works to minimize the potential effects of
individual biases.
In a 12-page response to Sen. John Thune, (R., S.D.), Facebook
said a review found that conservative and liberal topics were
approved for the trending feature at "virtually identical rates."
The two most frequent topics since early 2015, Facebook said, are
Republican presidential candidate Donald Trump and the subject
"#GOPDebate."
Still, Facebook said it couldn't rule out the possibility of
"isolated improper actions or unintentional bias" by workers in how
trending topics are selected. The company said it is making several
changes intended to "minimize risks where human judgment is
involved."
Among other things, Facebook said the curators who assemble and
approve topics will no longer rely on external websites and news
outlets to assess the importance of potential topics. Facebook said
it its adding more oversight to the trending topics team, but
didn't offer specifics.
The letter is Facebook's latest attempt to contain the fallout
from a May 9 report published by tech blog Gizmodo that said
curators of Facebook's "trending topics" feature suppressed news
about conservative events and from conservative sources. Facebook
denied bias but revealed that curators had more oversight over what
appears in this feed than it previously disclosed.
The Gizmodo report prompted Mr. Thune to send a letter to
Facebook Chief Executive Mark Zuckerberg asking how trending topics
are selected. On May 18, Facebook general counsel Colin Stretch met
Mr. Thune, the chairman of the Senate Commerce Committee. That same
day 16 top conservatives met Mr. Zuckerberg at Facebook's
headquarters in Menlo Park, Calif.
"The seriousness with which Facebook has treated these
allegations and its desire to serve as an open platform for all
viewpoints is evident and encouraging and I look forward to the
company's actions meeting its public rhetoric," Mr. Thune said in a
statement Monday, in response to Facebook's letter.
One conservative who attended the meeting with Mr. Zuckerberg
last week applauded Facebook's moves.
"I think this is a good step," said Brent Bozell, president of
conservative media watchdog the Media Research Center, in a
statement. "Facebook was relying on a preponderance of liberal and
leftist 'news' organs. By not relying on any specific news outlets,
Facebook returns to its neutral roots."
Other conservatives were unmoved.
"This issue is still unresolved even after these admissions of
wrongdoing by Facebook," said Matt Schlapp, chairman of the
American Conservative Union, which hosts the annual Conservative
Political Action Conference. "We will continue to press this matter
until we are satisfied that conservatives will be fairly
treated."
Mr. Schlapp said previously that he declined Facebook's
invitation to meet Mr. Zuckerberg last week.
Facebook said it couldn't examine reviewer decisions before
December 2014 due to a lack of "reliable data logs." Gizmodo said
it interviewed people who worked on trending topics between
mid-2014 and December 2015. To draft its response, Facebook said it
analyzed all trending topics reviewed by its curators during the
past 90 days. The company looked at more than 3,000 decisions to
see if conservative or liberal topics were disproportionately
boosted or suppressed by reviewers. It interviewed current and
former reviewers.
Facebook said the review uncovered no bias against conservative
news sources or topics. It said it reviewed more than 600 decisions
involving specific topics that the Gizmodo article suggested had
been suppressed and found that topics related to Republican Texas
Sen. Ted Cruz, commentator Glenn Beck, former Navy SEAL Chris Kyle
and former Internal Revenue Service official Lois Lerner had all
been accepted.
On another topic raised by the Gizmodo article, Facebook said
the Conservative Political Action Conference had been accepted as a
topic on each of its three days in 2015 and two days in 2016. The
day the conference wasn't included, Facebook said, was the day
after the 2016 Super Tuesday primaries, when at least 15 other
topics related to the Republican presidential campaign were
accepted. There was no way to independently verify Facebook's
conclusions.
Facebook said it uses as computer program to identify potential
trends from the vast amount of content posted on the social network
each day. More than 1.6 billion people world-wide, including 222
million in the U.S. and Canada, check Facebook at least once a
month.
Facebook said it uses human editors "to bridge the gap between
what an algorithm can do today and what we hope it will be able to
do in the future."
Prior to Monday's changes, curators on the team relied on a
variety of external sources to identify and verify trending topics.
They assigned an "importance level" to news stories based on how
they were covered by 10 major news outlets, including The Wall
Street Journal, Fox News, the New York Times and the Huffington
Post. They also used a list of 1,000 media publications known
internally as the "Media 1K" to help write topic descriptions.
Under the new rules, the team will no longer rely on external
websites and news outlets; they will have to rely on Facebook's
internal data to vet and select its "trending topics."
They will only be able to use chatter on Facebook to surface
trending topics and all topics will now be assigned the same level
of importance, a Facebook spokeswoman said.
Reviewers will use Facebook search results to help them write
descriptions. Facebook is also adding more oversight over the
trending topics team, but didn't describe this oversight.
The trending topics feature was introduced in 2014 as part of
Facebook's broader effort to become a source of real-time
information. It is set to the right of the news feed on Facebook's
desktop page; it appears on the mobile app when a user taps the
search bar.
