#socialchoice — Public Fediverse posts

Wikimedia communities and volunteers should experiment more with modern decision-making tools. The Request for Comments in particular has some serious downsides and is not suitable for every decision. https://diff.wikimedia.org/2026/07/03/we-need-to-innovate-with-wikimedia-decision-making/ #wikimedia #wikipedia #socialchoice

Enlightenment thinkers built democracy on a fiction: rational citizens who never existed

I’ve distilled the argument into a six-premise syllogism — a logical skeleton that shows how institutional assumptions collapse against human cognition, Arrow’s impossibility theorem, and Dunbar’s limits of scale.

I was thinking about voting systems earlier: has there been research into a system where the probability of a decision being made is a monotonic function of its votes?

https://en.wikipedia.org/wiki/Random_ballot is just this but with the function being the identity, but I wonder if others have been explored.

📢#OutNow in #OA: 'Models in #Microeconomic Theory: Expanded Second Edition (She & He)' by Martin J. Osborne & Ariel Rubinstein.

Part I presents models of an #economic agent, discussing abstract models of preferences, choice, and decision-making under uncertainty, before turning to models of the #consumer, the #producer, and #monopoly. Part II introduces the concept of #equilibrium, beginning, unconventionally, with the models of the jungle and an #economy with indivisible goods, and continuing with models of an exchange economy, equilibrium with rational expectations, and an #economy with asymmetric information. Part III provides an introduction to #gametheory, covering #strategic and extensive #games and the concepts of #Nash #equilibrium and #subgame perfect equilibrium. Part IV gives a taste of the topics of #mechanismdesign, #matching, the #axiomatic analysis of #economic systems, and #socialchoice.
