There's no reason to require polyticians to be technicians, and no reason to expect less formally-educated people to be more anti nuclear (except in the presence of massive disinformation campaigns). Requirements for formal education just select for conservative and obedient people - and we put them on the leaders (we got it backwards!). The US seems to kind of got it a bit more right, but it's probably just circus.

Technocratic politics doesn't work in practice (ask USSR), and there should be no requirements of formal education on politicians (not even non technical). But politicians and administrators do need to (re)learn fast on-the-lob so in practice an IQ test requirement would be great for them and probably for them only (yes, IQ measures well only how fast someone can learn something and not at all how good is someone at doing something after they've learned it, but, guess what... knowing and (re)learning fast about stuff they don't actually do is kind of the job requirement for politicians and administrators - an 145 IQ high-school-dropout with or without some alchol or substance issues is kind of the best person for a job like Prime Minister, Energy or Finance Minister etc.).

Oh, and on the active (we know their effects, so they must exist) campaigns of disinformation against known to work tech, there's a solution for that: laws for spreading false-facts and disinformation + throwing in jail people breaking them. Glue your ass on the highway or spread misinformation on facebook fueling anti-nuclear protests: how about a 5 years prison sentence baby?

As a society we're so f terrible at allocating human resources, that it's no wonder that other resources like those involved in energy production are massively missalocated too...
