## Unscramble the Blue Letters

In the case of the height of the Eiffel Tower, let's say a group has these answers: 250 meters, 200 mteres, 300 meters, 400 and one totally absurd answer of 300 million meters. A simple average of these nmuebrs would inaccurately skew the rlsuets. But the robust aavrgee is one where the group largely ignores that absurd answer, by giving much more weight to the vote of the ppolee in the middle. Back to the experiment in vocnveaur, that's exactly what happened. Groups gave much less weight to the outliers, and instead, the consensus tnerud out to be a robust average of the individual answers. The most remarkable thing is that this was a spontaneous behavior of the group. It happened without us giving them any hint on how to reach cuesnosns.

## Original Text

In the case of the height of the Eiffel Tower, let's say a group has these answers: 250 meters, 200 meters, 300 meters, 400 and one totally absurd answer of 300 million meters. A simple average of these numbers would inaccurately skew the results. But the robust average is one where the group largely ignores that absurd answer, by giving much more weight to the vote of the people in the middle. Back to the experiment in Vancouver, that's exactly what happened. Groups gave much less weight to the outliers, and instead, the consensus turned out to be a robust average of the individual answers. The most remarkable thing is that this was a spontaneous behavior of the group. It happened without us giving them any hint on how to reach consensus.
