A BLOG 

A blog: " De Borda abroad."  From Belfast to Beijing and beyond... and back. Starting in Vienna with the TEDx talk, I go by bus and/or train for more debates in Belgrade, Sarajevo, Istanbul, Tbilisi, Yerevan and Tehran, before flying - sorry about that - to Urumqi in Xīnjiāng, followed by more debates in Beijing, Tianjin, Hong Kong and Taiwan... but not in Pyongyang. Then back via Mongolia (where I was an election observer last year) and Moscow (where I worked in the '80s).

I have my little fold-up Brompton with me - surely the best way of exploring any new city! So I fly hardly at all; I go by train, boat or bus if possible, and then cycle wherever in each new venue; and all with just one plastic water bottle... or that was the intention!

About us

Visit us on Facebook

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 voting procedures for use in decision-making and even more electoral systems.  This is because, in decision-making, there is usually only one outcome; but with some electoral systems, as in any proportional ones, there can be several winners.  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!

FAQ on > What is a Preferendum? > What happens in an mbc if people vote for only some, or only one option?

Search the FAQ for entries containing:

In a 5-option ballot paper, if I vote for only my favourite option, my favourite gets just 1 point.

If you vote for 2 options, your favourite gets 2 points and your 2nd preference gets 1 point.

If a third person votes for 3 options, his favourite gets 3 points, his 2nd preference gets 2 points, and his 3rd preference gets 1 point.

If a fourth person votes for 4 options, her favourite gets 4 points, her 2nd preference gets 3 points, her 3rd preference gets 2 points, and her 4th preference gets 1 point.

So, if you want your favourite to get the maximum score of 5 points, the best thing to do is to cast all your preferences.

In other words, your favourite (if stated) gets 1 point more than your 2nd preference (whether stated or not); your 2nd preference (if stated) gets 1 point more than your 3rd preference (whether stated or not); and so on. No one is forcing you to express all your preference, but the system encourages you to do so. And no matter how you vote, the difference is always 1 point; there is no especial weighting or any other form of bias in the procedures.
