     <p>The key idea of our credibility calculation was evidence. You could add Factlinks as evidence for another Factlink. This evidence could be either supporting or weakening. If the <span class="blog-fact-graph-supporting"><i class="icon-plus-circled"></i> supporting Factlink</span> was likely to be <span class="blog-fact-graph-agree">true</span>, then the Factlink it supported was also more likely to be <span class="blog-fact-graph-agree">true</span>. If a <span class="blog-fact-graph-weakening"><i class="icon-minus-circled"></i> weakening Factlink</span> was likely to be <span class="blog-fact-graph-agree">true</span>, then the Factlink it weakened was more likely to be <span class="blog-fact-graph-disagree">false</span>. We called this network of evidence the “Fact Graph”.</p>
   
  -  <p>An example. <span class="blog-fact-graph-f1">Factlink 1 (F1)</span> is: <span class="blog-fact-graph-factlink blog-fact-graph-f1">“Working from home is more productive than working in an office.”</span> You could find some evidence on a website that talks about personal experience, and annotate <span class="blog-fact-graph-f2">F2</span>: <span class="blog-fact-graph-factlink blog-fact-graph-f2">“I’m much happier working from home, so I work harder.”</span> You can add <span class="blog-fact-graph-f2">F2</span> as <span class="blog-fact-graph-supporting"><i class="icon-plus-circled"></i> supporting evidence</span> to <span class="blog-fact-graph-f1">F1</span>. If it turns out that <span class="blog-fact-graph-f2">F2</span> is <span class="blog-fact-graph-agree">very credible</span> &mdash; many people voted that they agree, or it gets a lot of supporting evidence &mdash; then in turn <span class="blog-fact-graph-f1">F1</span> will also become <span class="blog-fact-graph-agree">more credible</span>. The green part of the Factwheel of <span class="blog-fact-graph-f1">F1</span> will become bigger.</p>

     <p>Say you find a counter argument on the web, which you annotate. <span class="blog-fact-graph-f3">F3</span>: <span class="blog-fact-graph-factlink blog-fact-graph-f3">“In conclusion, in 89% of the cases we have looked at, working in the office was most productive.”</span> This one might be added as <span class="blog-fact-graph-weakening"><i class="icon-minus-circled"></i> weakening evidence</span> to <span class="blog-fact-graph-f1">F1</span>. If it turns out <span class="blog-fact-graph-f3">F3</span> is <span class="blog-fact-graph-agree">credible</span>, then <span class="blog-fact-graph-f1">F1</span> becomes <span class="blog-fact-graph-disagree">less credible</span>.

positive.code:     <li>You could click a colour on the Factwheel to cast a vote, for whether you <span class="blog-fact-graph-agree">agree</span>, <span class="blog-fact-graph-disagree">disagree</span>, or are <span class="blog-fact-graph-unsure">unsure</span>.</li>
    </ol>
  
    <p>Initially, we started out with just voting. If you agreed, you clicked the green part, which would grow a little. And the number inside the circle would become larger. The same for the red and blue parts.</p>

    <p>Once you created a Factlink on a website, other people with the browser extension could see it. It didn’t modify the website directly, as that’s generally not possible, but it altered how the website is rendered using the browser extension.</p>
  
    <p>You could then post the Factlink to a channel, such as “Brain development”. Others who subscribed to that channel, such as experts or interested people, would see the Factlink on their activity feed. They could then give their opinion, add sources, and comment on the Factlink.</p>
