So thanks for digging up the archive link to that page. A little bit of annotation around that link would be wonderful. Hopefully an active Electowiki editor can perform the plagiarism-free restatement I was hoping for. -- [[User:RobLa|RobLa]] ([[User talk:RobLa|talk]]) 05:04, 8 January 2020 (UTC)
== EPOV on Arrow and cardinal methods ==
Just a bit ago, I posted a message to the [[EM list]] about Arrow's theorem and cardinal methods. I'll quote a little bit of the message here:
<blockquote>
Many Score voting[1] activists claim that cardinal methods somehow
dodge Arrow's theorem. It seems to me that *all* voting systems (not
a mere subset) are subject to some form of impossibility problem.
Arrow's impossibility theorem deserved great acclaim for subjecting
all mainstream voting systems of the 1950s to mathematical rigor, and
it's clear that his 1950 paper and 1951 book profoundly influenced
economics and game theory for the better. His 1972 Nobel prize was
well deserved. It seems that it has become fashionable to find
loopholes in Arrow's original formulation and declare the loopholes
important. Even if the loopholes exist, talking up those loopholes
doesn't seem compelling, given the subsequent work by other theorists
broaden the scope beyond Arrow's version.
</blockquote>
I expand on these points quite a bit in my email. The full message is archived here: "'''[http://lists.electorama.com/pipermail/election-methods-electorama.com/2020-January/002403.html (EM) Arrow's theorem and cardinal voting systems]'''". I'm eager to read what the membership there thinks on this topic, since that group of people has frequently been successful at changing my mind on a particular topic. I'm also eager to read your response to my message (privately or publicly, via whatever mode of communication you prefer). -- [[User:RobLa|RobLa]] ([[User talk:RobLa|talk]]) 23:47, 9 January 2020 (UTC)
