the strongest political bias of all

The strongest bias in American politics is not a liberal bias or a conservative bias; it is a confirmation bias, or the urge to believe only things that confirm what you already believe to be true. Not only do we tend to seek out and remember information that reaffirms what we already believe, but there is also a “backfire effect,” which sees people doubling down on their beliefs after being presented with evidence that contradicts them. So, where do we go from here? There’s no simple answer, but the only way people will start rejecting falsehoods being fed to them is by confronting uncomfortable truths.

Digital's impact on Politics

In party politics, some worry that the digital targeting of voters might end up reducing the democratic process to a marketing exercise. Ever more data and better algorithms, they fret, could lead politicians to ignore those unlikely to vote for them. And in cities it is not clear that more data will ensure that citizens become more engaged.

When the internet first took off, the hope was that it would make the world a more democratic place. The fear now is that the avalanche of digital information might push things the other way. Viktor Mayer-Schönberger, a data expert at the University of Oxford, sums up the problem: “Data are mainly helping those who already have information power.”
