 A related line of research focuses on  the  influence of  factors,  such as polls (Reijngoud and Endriss 2012),  social networks (Santoro and Beck 2017, Stirling 2016) and deliberation  among the voters (List 2018), on the profiles of ballots that are actually  realized  in an election.  For instance, List et al. 2013 has evidence  suggesting that deliberation reduces the probability of a Condorcet cycle occurring.
