I am a proponent of representative democracy, of checks and balances, and of democratic institutions that carefully examine problems making good use of all the expertise available.
Representing people is a two way street. It also means for politicians to tell people the truth and to convince them of supporting the right thing having considered all the evidence, trade-offs and shared goals.
Democratic institutions have a lot of resources available to them and a lot of time that the average voter does not have. They should make use of those resources, not lazily ape voters and exploit possibly irrational fears.
I guess if you still want to keep the democracy and have your 5G in Brussels you better convince enough Brusselians that the speed increase in networking is worth risking more cancer or that EM radiation definitely does not increase health risk.
But when I said that I didn't want to rely on average voters' risk percpetion, I didn't actually mean any of that. I merely meant that I don't rely on it to form my own opinion (which is definitely not subject to a popularity contest).
I don't want to convince the people of Brussels of anything. I want to know the truth about the health effects of 5G, and I hope that our democracies are not too dysfunctional to let that truth inform any regulations.
If we don't know anything about the effects of 5G, it could just as well be the cure for cancer.
But it's not a coin toss. We do know some things about how it works, we have decades of empirical data on similar technologies, and ultimately we always have to act in spite of uncertainty as even the effects of doing nothing are uncertain.
