Wisdom of crowds methodology
11
Why wisdom of crowds? Scottish referendum 2014 – much less close than polls predicted Maybe people report other’s behaviour more reliably than their own Surowiecki’s 2004 book – “The Wisdom of Crowds”
12
Criteria for a wise crowd
Criterion Explanation How addressed by sample surveys Diversity of opinion Each person should have private information even if it's just an eccentric interpretation of the known facts. We draw a random sample; people are not selected based on any relationship to the issue in question. Independence People's opinions aren't determined by the opinions of those around them. This is more questionable, especially if we are asking people what they believe is the consensus opinion of others. Decentralization People are able to specialize and draw on local knowledge. We (attempt to) draw a nationally representative sample Aggregation Some mechanism exists for turning private judgments into a collective decision. We arrive at the collective decision by simple aggregation of responses.

We have a solution. All we need now is to find the problems it helps solve.
