A blog: I'm going to China. Starting in Vienna with a TEDx talk, I then head to Belgrade, Sarajevo, Tbilisi, Baku and Kabul, before catching a bus across Tajikistan to Kashgar, 喀什, in Xīnjiāng, 新疆, where I hope to buy a bicycle.  https://debordaabroad.wordpress.com/2017/09/07/de-borda-abroad/

About us

The de Borda Institute aims to promote the use of inclusive voting procedures on all contentious questions of social choice.

This applies specifically to decision-making, be it for the electorate in regional/national polls, for their elected representatives in councils and parliaments, for members of a local community group, for members of a company board, for members of a co-operative, and so on.

WELCOME

Welcome to the home page of the de Borda Institute, a Northern Ireland-based international organisation (an NGO) which aims to promote the use of inclusive voting procedures on all contentious questions of social choice. For more information use the menu options above or feel free to contact the organisation's headquarters. If you want to check the meaning of any of the terms used, then by all means have a look at this glossary.

As shown in these attachments, there are many decision-making and even more electoral systems.  Sometimes, for any one voters' profile - that is, the set of all their preferences - the outcome of any count may well depend on the voting procedure used.  In this very simple example of a few voters voting on just four options, and in these two hypothetical examples on five, (word document) or (power-point) in which a few cast their preferences on five options, the profiles are analysed according to different methodologies, and the winner could be any one of all the options.  Yet all of these methodologies are called democratic!  Extraordinary!

FIDDLERS' GREEN FESTIVAL, ROSTREVOR, CO DOWN, 26.7.2012

 

At the invitation of Tommy Sands, Peter Emerson and Grace Walsh facilitated a decision-making process based on consensus voting.  Here is the report.

______

The MBC is a very good measure of a group's social choice (and/or ranking), and so too is the Condorcet rule.  In many instances, therefore, the outcomes under both rules will be similar and, when they are, the users can rest assured that the outcome is accurate.

At a recent public meeting here in Rostrevor (County Down), 96 participants selected the subject of discussion, chose and debated many proposals, and then voted on a ballot of nine options.  The results were as follows:

 

VALID VOTE                                     96

VALID FULL VOTE                             82

VALID PARTIAL VOTE                        14

INVALID VOTE                                   0

The social choice, therefore, is option D.  And in this instance, the MBC social choice and ranking are identical to the Condorcet social choice and ranking.  The above outcome may therefore be regarded as very accurate indeed.

The debate concerned the possibility of a crossing from Warren Point (or thereabouts) across Carlingford Lough to County Louth.  The options suggested were as follows:

A  Status quo

B  Ferry

C  Cars only road bridge

D  Bridge for everything

E  Swing bridge (opens for boats)

F  Tunnel

G  Bridge but only with North/South funding

H  Southern relief road

I  Cable car
