Maybe only those who pass a stringent test should be allowed to vote?
I fundamentally disagree with this.
There is a problem though. The media is supposed to act as a filter for information to the public. It is supposed to say whether Mr x from the y party is spouting utter bollocks. The problem has come as social media has broken down that role and made it financially impossible for traditional media to do that effectively whilst social media has no filter at all.
The net result is the public - who used to be able to trust what they were told, no longer do, but they also have not developed the skills to critically examine what they are told, or lack the time to, or simply are not interested enough to take enough of an interest to look beyond the surface.
It's not about being stupid. It's about people often just falling into the habit of believing what they'd like to hear and ignoring things that are more challenging or difficult or controversial.
People haven't got time to look up what WTO does or doesn't mean. Or what the EU really does. Or doesn't do.
Cos they don't really care.
There's many highly intelligent people who ultimately fall into this. They feel secure enough that if it's bad, they'll ultimately be fine anyway or conversely think it can't get any worse than it already is and they have nothing left to lose.
Politics are complicated and boring. That's a turn off for most. And that's the real issue.
