> Representatives voting in complete ignorance would vote 50/50, on average.
Why?
> However, some representatives will actually have the technical knowledge needed to vote properly
By "properly", you mean "agreeing with me", right? This does not require any technical knowledge.
> so the majority would probably fall in NN's favour.
You implying everybody that has technical knowledge supports NN, and only reason to oppose it is ignorance. This is wrong and incredibly condescending.
> What do you think the vote ratio would look like if they only received biased information from lobbyists
Depends on how biased it is. If it's biased in favor of NN, the ratio would be something different than if it's biased against NN.
> Suddenly voting in ignorance doesn't sound too bad
Yes it does. Why would we need any Congress at all then? We could replace them with a cheap one cent coin and save a lot of money and drama. The point of representative government is that it is a focus point of an effort to figure out the right thing to do, and that all participants at least kinda trying to do it. If it's just random, there's no point of wasting effort on it, we can do much better random much cheaper.
> whereby a group of independent voters can make better aggregate decisions than any single voter,
I agree, having elections makes more sense than having a King.
> However, this breaks down if the votes are no longer independent.
Nobody is truly independent in a modern society. Not even a King - historically, there were lots of weak monarchs manipulated by their courts and seconds in command. Neither a person living in a modern society. Of course people influence other people. And this can produce negative effects like groupthink and mass panics. So what's your suggestion - ban talking about politics? Mind-wiping congressmen before voting?
