0:00:06.761,0:00:10.560
There's a quote usually attributed[br]to the writer Mark Twain that goes,

0:00:10.560,0:00:14.211
"A lie can travel [br]halfway around the world

0:00:14.211,0:00:17.269
while the truth is putting on its shoes."

0:00:17.269,0:00:18.936
Funny thing about that.

0:00:18.936,0:00:22.985
There's reason to doubt[br]that Mark Twain ever said this at all,

0:00:22.985,0:00:26.000
thus, ironically, proving the point.

0:00:26.000,0:00:31.753
And today, the quote, whoever said it,[br]is truer than ever before.

0:00:31.753,0:00:35.180
In previous decades, [br]most media with global reach

0:00:35.180,0:00:38.496
consisted of several [br]major newspapers and networks

0:00:38.496,0:00:43.062
which had the resources[br]to gather information directly.

0:00:43.062,0:00:45.722
Outlets like Reuters[br]and the Associated Press

0:00:45.722,0:00:51.921
that aggregate or rereport stories[br]were relatively rare compared to today.

0:00:51.921,0:00:54.846
The speed with which [br]information spreads now

0:00:54.846,0:01:00.623
has created the ideal conditions for[br]a phenomenon known as circular reporting.

0:01:00.623,0:01:04.225
This is when publication A[br]publishes misinformation,

0:01:04.225,0:01:06.916
publication B reprints it,

0:01:06.916,0:01:12.807
and publication A then cites B[br]as the source for the information.

0:01:12.807,0:01:15.433
It's also considered a form[br]of circular reporting

0:01:15.433,0:01:17.871
when multiple publications

0:01:17.871,0:01:21.122
report on the same initial piece [br]of false information,

0:01:21.122,0:01:27.414
which then appears to another author as[br]having been verified by multiple sources.

0:01:27.414,0:01:32.678
For instance, the 1998 publication[br]of a single pseudoscientific paper

0:01:32.678,0:01:36.667
arguing that routine vaccination[br]of children causes autism

0:01:36.667,0:01:40.584
inspired an entire [br]antivaccination movement,

0:01:40.584,0:01:44.697
despite the fact that the original paper[br]has repeatedly been discredited

0:01:44.697,0:01:47.173
by the scientific community.

0:01:47.173,0:01:52.157
Deliberately unvaccinated children[br]are now contracting contagious diseases

0:01:52.157,0:01:56.007
that had been virtually [br]eradicated in the United States,

0:01:56.007,0:01:58.803
with some infections proving fatal.

0:01:58.803,0:02:00.890
In a slightly less dire example,

0:02:00.890,0:02:04.676
satirical articles that are formatted[br]to resemble real ones

0:02:04.676,0:02:09.236
can also be picked up by outlets[br]not in on the joke.

0:02:09.236,0:02:14.362
For example, a joke article in the[br]reputable British Medical Journal entitled

0:02:14.362,0:02:19.513
"Energy Expenditure in Adolescents[br]Playing New Generation Computer Games,"

0:02:19.513,0:02:25.548
has been referenced in serious[br]science publications over 400 times.

0:02:25.548,0:02:27.999
User-generated content, such as wikis,

0:02:27.999,0:02:31.853
are also a common contributer[br]to circular reporting.

0:02:31.853,0:02:35.869
As more writers come to rely[br]on such pages for quick information,

0:02:35.869,0:02:41.137
an unverified fact in a wiki page[br]can make its way into a published article

0:02:41.137,0:02:46.213
that may later be added as a citation[br]for the very same wiki information,

0:02:46.213,0:02:49.038
making it much harder to debunk.

0:02:49.038,0:02:51.517
Recent advances [br]in communication technology

0:02:51.517,0:02:53.436
have had immeasurable benefits

0:02:53.436,0:02:57.518
in breaking down the barriers[br]between information and people.

0:02:57.518,0:02:59.315
But our desire for quick answers

0:02:59.315,0:03:03.335
may overpower the desire [br]to be certain of their validity.

0:03:03.335,0:03:07.574
And when this bias can be multiplied by[br]billions of people around the world,

0:03:07.574,0:03:11.877
nearly instantaneously,[br]more caution is in order.

0:03:11.877,0:03:13.832
Avoiding sensationalist media,

0:03:13.832,0:03:16.980
searching for criticisms [br]of suspicious information,

0:03:16.980,0:03:22.088
and tracing the original source[br]of a report can help slow down a lie,

0:03:22.088,0:03:25.360
giving the truth more time [br]to put on its shoes.
