تكثيف جهودنا حول العالم للحد من انتشار المعلومات الخاطئة
لقد أثمرت جهودنا في الحد من المعلومات الخاطئة عن نتائج ملموسة، ولكن توسيع نطاق هذه الجهود لتشمل عشرات اللغات ومئات البلدان التي نعمل بها ليس أمرًا سهلاً ولا يخلو من الصعوبات.
تختلف آلية تحديد المصادر الموثوقة من بلد إلى آخر. ففي حين تُعتبر قنوات البث العامة، مثل BCC في المملكة المتّحدة، مصدرًا معتمدًا للأخبار في بعض البلدان، يعتبرها البعض في بلدان أخرى مصدرًا للدعاية ونشر المعلومات المتحيّزة. تختلف أيضًا طريقة التعامل مع المحتوى الإخباري والمعلومات من بلد إلى آخر، فالبعض يفرض معايير صارمة للتحقّق من صحة الأخبار بينما يكتفي البعض الآخر بقليل من الإشراف وعمليات التحقّق فقط. بالإضافة إلى ذلك، يمكن للأخبار العاجلة أو الأحداث السياسية أو الأحداث ذات السياق التاريخي أن تؤدي إلى انتشار قصص مضلّلة محلية يكون لها تداعيات على بلد معيّن دون سواه. من الأمثلة على ذلك إلقاء البعض باللوم على نظريات المؤامرة الدولية في تفشّي مرض "زيكا" في البرازيل، أو انتشار الشائعات في اليابان مؤخرًا حول حدوث زلزال سببه تدخّل بشري.
بالنظر إلى هذه الاختلافات بين المناطق والبلدان، تواجه فرق عملنا العديد من المشاكل نفسها التي تواجهها في الحد من انتشار المعلومات الخاطئة، مثل تغيّر المعلومات المتوفرة عن موضوع معيّن أو عدم توفّر مصادر موثوقة كافية. لعلّ خير مثال على ذلك ما حصل في بداية الجائحة، حيث لم تتوفّر في جميع البلدان معلومات محدّثة من هيئات الصحة المحلية، وفي بعض الأحيان قدّمت هذه الهيئات إرشادات متضاربة.
يمكن أن تختلف إلى حد كبير أيضًا آلية تحديد المحتوى القريب من مخالفة سياساتنا، وذلك لأنّ تفسير إرشادات تقييم المحتوى لدينا قد يختلف حسب اللغة أو الثقافة المحلية. نحن نأخذ هذا الأمر في الحسبان دائمًا عند تطوير الإرشادات ونستغرق وقتًا طويلاً في العمل مع الفرق والخبراء المحليين لتحديد السياقات الثقافية التي تحدّد ما إذا كان الفيديو على وشك مخالفة السياسات أم لا.
إلى جانب تنمية فرق عملنا لتضمّ المزيد من الأشخاص ذوي الخبرة في تحديد الفروقات الثقافية الإقليمية المتداخلة مع المعلومات الخاطئة، فإنّنا ندرس الاستثمار في المزيد من الشراكات مع أصحاب الخبرة والمؤسسات غير الحكومية حول العالم. وعلى غرار نهجنا في التعامل مع المواضيع الرائجة، إنّنا نعمل حاليًا على تطوير حلول تحدّث نماذجنا بشكل متكرّر حتى تتمكّن أنظمتنا من رصد المعلومات الخاطئة التي تستهدف بلدًا محدّدًا، حتى لو كانت منشورة باللغة المحلية للبلد.

Neal’s Responsibility Update
Billions of people from around the world come to YouTube for every reason imaginable. Whether you’re looking to watch a hard-to-find concert, or planning to learn a new skill, YouTube connects viewers with an incredible array of diverse content and voices. But none of this would be possible without our commitment to protect our community — this core tenet drives all of our systems and underpins every aspect of our products.
A few times a year, I’ll bring you behind the scenes into how we’re tackling some of the largest challenges facing YouTube and the tradeoffs behind each action we’re considering. In future installments, we might explore topics like our policy development work, shed more light on the thinking behind a thorny issue or generally outline key responsibility milestones. But for this first edition, I want to dig into our ongoing work addressing potentially harmful misinformation on YouTube.
Over the past five years, we’ve invested heavily in a framework we call the 4Rs of Responsibility. Using a combination of machine learning and people, we remove violative content quickly, raise up authoritative sources, and reduce the spread of problematic content (I discussed in-depth why in a blog post here). These tools working together have been pivotal in keeping views of bad content low, while preserving free expression on our platform. And yet, as misinformation narratives emerge faster and spread more widely than ever, our approach needs to evolve to keep pace. Here are the next three challenges our teams are looking to tackle.
Catching new misinformation before it goes viral
For a number of years, the misinformation landscape online was dominated by a few main narratives – think 9/11 truthers, moon landing conspiracy theorists, and flat earthers. These long-standing conspiracy theories built up an archive of content. As a result, we were able to train our machine learning systems to reduce recommendations of those videos and other similar ones based on patterns in that type of content. But increasingly, a completely new narrative can quickly crop up and gain views. Or, narratives can slide from one topic to another—for example, some general wellness content can lead to vaccine hesitancy. Each narrative can also look and propagate differently, and at times, even be hyperlocal.
We faced these challenges early on in the COVID-19 pandemic, such as when a conspiracy theory that 5G towers caused the spread of coronavirus led to people burning down cell towers in the UK. Due to the clear risk of real-world harm, we responded by updating our guidelines and making this type of content violative. In this case we could move quickly because we already had policies in place for COVID-19 misinformation based on local and global health authority guidance.
But not every fast-moving narrative in the future will have expert guidance that can inform our policies. And the fresher the misinfo, the fewer examples we have to train our systems. To address this, we’re continuously training our system on new data. We’re looking to leverage an even more targeted mix of classifiers, keywords in additional languages, and information from regional analysts to identify narratives our main classifier doesn’t catch. Over time, this will make us faster and more accurate at catching these viral misinfo narratives.
In addition to reducing the spread of some content, our systems connect viewers to authoritative videos in search results and in recommendations. But certain topics lack a body of trusted content—what we call data voids. For example, consider a fast-breaking news event like a natural disaster, where in the immediate aftermath we might see unverified content speculating about causes and casualties. It can take trusted sources time to create new video content, and when misinformation spreads quickly, there isn’t always enough authoritative content we can point to in the short term.
For major news events, like a natural disaster, we surface developing news panels to point viewers to text articles for major news events. For niche topics that media outlets might not cover, we provide viewers with fact check boxes. But fact checking also takes time, and not every emerging topic will be covered. In these cases, we’ve been exploring additional types of labels to add to a video or atop search results, like a disclaimer warning viewers there’s a lack of high quality information. We also have to weigh whether surfacing a label could unintentionally put a spotlight on a topic that might not otherwise gain traction. Our teams are actively discussing these considerations as we look for the right approach.
The cross-platform problem - addressing shares of misinformation
Another challenge is the spread of borderline videos outside of YouTube – these are videos that don’t quite cross the line of our policies for removal but that we don’t necessarily want to recommend to people. We’ve overhauled our recommendation systems to lower consumption of borderline content that comes from our recommendations significantly below 1%. But even if we aren’t recommending a certain borderline video, it may still get views through other websites that link to or embed a YouTube video.
One possible way to address this is to disable the share button or break the link on videos that we’re already limiting in recommendations. That effectively means you couldn’t embed or link to a borderline video on another site. But we grapple with whether preventing shares may go too far in restricting a viewer’s freedoms. Our systems reduce borderline content in recommendations, but sharing a link is an active choice a person can make, distinct from a more passive action like watching a recommended video.
Context is also top of mind — borderline videos embedded in a research study or news report might require exceptions or different treatment altogether. We need to be careful to balance limiting the spread of potentially harmful misinformation, while allowing space for discussion of and education about sensitive and controversial topics.
Another approach could be to surface an interstitial that appears before a viewer can watch a borderline embedded or linked video, letting them know the content may contain misinformation. Interstitials are like a speed bump – the extra step makes the viewer pause before they watch or share content. In fact, we already use interstitials for age-restricted content and violent or graphic videos, and consider them an important tool for giving viewers a choice in what they’re about to watch.
We’ll continue to carefully explore different options to make sure we limit the spread of harmful misinformation across the internet.
Ramping up our misinformation efforts work around the world
Our work to curb misinformation has yielded real results, but complexities remain as we work to bring it to the 100+ countries and dozens of languages in which we operate.
Cultures have different attitudes towards what makes a source trustworthy. In some countries, public broadcasters like the BBC in the U.K. are widely seen as delivering authoritative news. Meanwhile in others, state broadcasters can veer closer to propaganda. Countries also show a range of content within their news and information ecosystem, from outlets that demand strict fact-checking standards to those with little oversight or verification. And political environments, historical contexts, and breaking news events can lead to hyperlocal misinformation narratives that don’t appear anywhere else in the world. For example, during the Zika outbreak in Brazil, some blamed the disease on international conspiracies. Or recently in Japan, false rumors spread online that an earthquake was caused by human intervention.
Faced with this regional diversity, our teams run into many of the same problems we see with emerging misinformation, from shifting narratives to lack of authoritative sources. For example, early on in the pandemic we saw that not all countries had the latest research available from their health authorities, and those local authorities sometimes had differing guidance.
What’s considered borderline can also vary significantly. We’re always accounting for how our content evaluators’ guidelines could be interpreted differently across languages and cultures. It takes time to work with local teams and experts to inform the cultural context that impacts whether a video is classified as borderline.
Beyond growing our teams with even more people who understand the regional nuances entwined with misinformation, we're exploring further investments in partnerships with experts and non-governmental organizations around the world. Also, similar to our approach with new viral topics, we’re working on ways to update models more often in order to catch hyperlocal misinformation, with capability to support local languages.
Building on our transparency
At YouTube, we’ll continue to build on our work to reduce harmful misinformation across all our products and policies while allowing a diverse range of voices to thrive. We recognize that we may not have all the answers, but we think it’s important to share the questions and issues we’re thinking through. There has never been a more urgent time to advance our work for the safety and wellbeing of our community, and I look forward to keeping you all informed along the way.
