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) |
