How many do you discover via google.com vs social networking sites like Facebook? The logistics of switching between discovering an article on Facebook and verifying it on google.com is cumbersome enough with short attention spans on web. If you consume content passively on mobile (as an increasing number of people do), there's no reasonable expectation you can be held to, to switch between Safari/ Chrome and Facebook every time you read something. Of all the articles you read in a day, how many do you yourself verify by looking them up? How many do you consider "plausible enough", hence never bother checking on their factuality? If something does conform to your pre-existing biases, you have zero incentive to actively look for something that challenges your opinion, but if a disclaimer was "right there", it might be harder for you to ignore.
