The same goes for any democratically appointed UX team.
On the other hand, we, the people are soon to vote whether Switzerland should terminate european human rights contracts. It's insanely democratic and it scares the shit out of me because it might actually get a majority.
You can shoot yourself in the foot with too much democracy.
The right wing fear machinery fed with millions of donation money has really poisoned the political climate over the last decade. Whether you agree with their points, a system like ours, where basically every citizen can trigger a nation wide vote about almost anything (e.g. reintroduction of death penalty) only works if the debates are driven by reason, not populism. The other parties recently jumped on the same train, saying it's the only way to defend against those scare mongers … sigh
I still love our system, it gives the people not only power but also a sense of responsibility. It's not the government that fucked things up – you did. But it doesn't make a country completely immune to dedicated actors with enough influence and money like many believe.
I think, the same thing works with visual and interaction design. But you'd need a small group of people to make the basic UX decisions and write concise guidelines others can follow. Like Apples «Human Interface Guidelines»[0].
This isn't really purely democratic, but I think it's almost impossible to find the "one way of doing things" if everyone has their say in every micro decision.
For me its much more important to have consistent user experience than the details of it. Its like tab vs spaces in programming or semicolon vs no semicolon in Javascript. I have my personal preferences, but i'm fine with either one as long as it is consistent at least within the project.
