Aims of the Institute

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. The appropriate methodology is the Borda count or rather, its modernised form, the Modified Borda Count (MBC) or "Borda preferendum"; (it is also known as consensus voting).

FAQ on Inclusive Voting Procedures > Voting Systems > What is the Quota Borda System (QBS)?

Search the FAQ for entries containing:

QBS is an electoral system for use whenever an electorate is electing more than one person. In a general election, it should be used in multi-member constituencies of about 6 seats, if need be with a regional/national top-up.

QBS consists of a quota element, added to an MBC. In a 6-seater constituency, a quota is one seventh of the valid vote, plus 1.

The count proceeds in stages:

Stage I: if any candidate gains a quota of 1st preferences, he/she is deemed elected.

Stage II: if any pair of candidates gains 2 quotas, both candidates are deemed elected.

Stage III: if any triplet of candidates gains 3 quotas, all three candidates are deemed elected.

Stage IV: if any triplet of candidates gain 2 quotas, the 2 candidates with the highest mbc scores are deemed elected.
Then if seats are still to be filled:

Stage V: if any pair of candidates gains a quota, the candidate with the higher MBC score is deemed elected.

Stage VI: if any triplet of candidates gains the quota , the candidate with the highest MBC score is deemed elected.
And finally, if seats still remain to be filled

Stage VII: those candidates with the highest MBC scores are deemed elected.
