Even if you manage to put the control of filtering in people's hands, it doesn't solve the problem. Social science convincingly shows people don't want to be told the truth if it runs counter to prior beliefs, and will use all the tools at their disposal to avoid or discredit it. In fact, forcing the truth on them will convince them even more of their false beliefs (see: the backfire effect). Give people more control over their filters, and they will create even tighter filter bubbles. Maybe the solution to what news to let through the filter bubble is to apply a very simple answer: none at all. Google shouldn't show anything that's more recent than a few weeks.
