Template talk:Electoral systems

Proposing a comprehensive update

I plan to make a number of changes to this template to address the following issues:

• Limited voting and Single non-transferable vote are misclassified as Simple majoritarianism.

• Plurality-at-large, General ticket, and Preferential block voting are misclassified as Mixed-member systems.

• The "Mixed-member" category should be "Mixed systems", consistent with the Electoral systems article.

Before renaming the "Mixed-member" category, I feel that the Mixed-Member Systems article should be renamed "Mixed electoral systems" and edited accordingly.

Once the above changes are done, there are a number of systems in the template that should be grouped differently. For example, I believe Coombs' method can be treated as a variant of Instant-runoff (alternative vote), and that the Oklahoma primary electoral system is a variant of Bucklin voting. On the other hand, Scorporo, Av+, and Parallel voting should not be listed as variants of the Additional member system. There are also a few systems such as biproportional apportionment that deserve to be added. Finally, I would do some rearranging to remove awkward terms and position the most prominent systems near the top of their respective categories.

The changes I'm proposing will result in the following structure:

        ** First-past-the-post

The update has been made (see this edit). There is now a new article: Mixed electoral system. The "Mixed-Member Systems" article has been moved back to its original name: Semi-proportional representation. Rhys Goldstein (talk) 16:08, 24 October 2017 (UTC)

Add listNname parameters

My suggestion for values is: plurality, proportional, mixed, other. This makes it possible to expand individual sections on relevant pages. 93.182.179.223 (talk) 16:59, 17 July 2019 (UTC)

Add link to positional voting within this template

The positional voting page incorporates this template but is not listed within it. Using this template, it is possible to navigate from positional voting to other electoral systems but not to navigate back to it.

Examples of positional voting electoral systems include the Borda count, the Nauru/Dowdall method and the Eurovision Song Contest (ESC) one. However, the Borda count employs an arithmetic progression of weightings whereas the Nauru/Dowdall method uses a harmonic progression instead and the ESC uses neither type. The latter two are sometimes called ‘variants’ of the Borda count but this word is unfortunate since the properties of different types of weighting progressions generate quite different ranking outcomes.

The Borda count is well known for being a system that promotes consensual candidates. At the other extreme, plurality (which can be analysed using positional weightings of 1, 0, 0, …, 0) promotes polarised candidates. Intermediate weightings (see here) between these two extremes often produce markedly different election outcomes. Referring to any positional voting system (or plurality!) as a ‘variant’ or ‘modified’ Borda count is simply misleading. The Nauru/Dowdall and ESC voting systems are accurately defined as positional voting ones but much less well as ‘sort-of’ Borda count ones.

Therefore, I would suggest amending this template as follows. Replace ‘Borda count’ with ‘Positional voting (Borda count, Nauru/Dowdall method, Eurovision Song Contest)’.Mencor (talk) 08:41, 3 May 2020 (UTC)

Change the label of the link to "CPO-STV" to say "CPO-STV" or "CPO" instead of "Wright". Icebound Alpaca (talk) 02:17, 31 October 2022 (UTC)

Done. --Mvqr (talk) 11:38, 31 October 2022 (UTC)
