An '''eigenpoll''' is a type of [[statistical survey]] which gathers knowledge from the community.  It differs from [[opinion poll]]s by finding the best solution, rather than finding the most popular opinion.

== History of eigenpolls ==
The eigenpoll is attributed to Knud Haugaard Sørensen.

== Methodology ==
The idea behind the eigenpoll is to let voters compare and rank options.  If the option is not present, respondents may add their own.  Through a series of selections, a score and rank is computed.  These results are continually updated as the polling progresses.

== Potential for inaccuracy ==
The results may be affected by [[response bias]], where the answers given may not truly reflect the opinion or beliefs of respondents.
