Well, we require a 2/3 majority because we prefer to have consensus about motions being put to vote before they are actually voted on. This means, if someone wants to propose a motion, they will initiate a discussion about the issue prior to voting on it. If the discussion looks favorable to their motion, a vote will be started. Having a 2/3 majority also prevents fragmentation within the team. We don’t want to have to resort to counting the votes and having 8 in favor and 7 against. If that is the case, there is most likely a problem that has not been discussed thoroughly enough. So, as a team we tend to resemble a consensus democracy more than a straight-up democracy where majority wins.
