In typical organizations, most decisions are made either autocratically, by a top-down leader, or democratically, where everyone shares their opinions and those opinions that have the most support are implemented. Both systems produce inferior decision making. That’s because the best decisions are made by an idea meritocracy with believability-weighted decision making, in which the most capable people work through their disagreements with other capable people who have thought independently about what is true and what to do about it.

It is far better to weight the opinions of more capable decision makers more heavily than those of less capable decision makers. This is what we mean by “believability weighting.” So how do you determine who is capable at what? The most believable opinions are those of people who 1) have repeatedly and successfully accomplished the thing in question, and 2) have demonstrated that they can logically explain the cause-effect relationships behind their conclusions. When believability weighting is done correctly and consistently, it is the fairest and the most effective decision-making system. It not only produces the best outcomes but also preserves alignment, since even people who disagree with the decision will be able to get behind it.

But for this to be the case, the criteria for establishing believability must be objective and trusted by everybody. At Bridgewater everyone’s believability is tracked and measured systematically, using tools such as Baseball Cards and the Dot Collector that actively record and weigh their experience and track records. In meetings we regularly take votes about various issues via our Dot Collector app, which displays both the equal-weighted average and the believability-weighted results (along with each person’s vote).
