We've already had some experiments about "what if we select politicians based on their love for being on TV and their lack of concern about concealing their corruption" and the results aren't good...
I'm more worried about the fact that humans are, collectively at least, so hypocritical.
For the following examples, bare in mind that neither I nor the general public understand the actual laws, so any nits you pick need to be the kind that even a non-lawyer will accept:
I'm old enough to remember Clinton being impeached for lying about his affairs, and yet Republicans (collectively) are defending Trump for lying about affairs.
Or vice versa, Trump's classified documents at home vs. Biden's.
Probably the same elsewhere, but I don't trust that I'm not part of the problem with regard to UK politics (where I'm from), and my German isn't good enough to pay attention to what's happening where I now live.
Humans are violent too. If we tried as hard to train it out of people we'd make good progress.
This is fundamental to loss aversion and compromise. There was never a "before." Open "negotiations" reward posturing, not compromise.
The old Ted Kennedy maneuver
On both sides. It's all theater like WWE. You have the good guy and you have the heel. Each side has their own story with this format.
