Investigating the effect of deliberate misreporting on opinion formation — •Vincent Kuhlen and Stefan Bornholdt — Institute for Theoretical Physics, University of Bremen, Germany

After elections one may observe the fact that opinion polls underestimated the votes for certain parties. If we assume no errors in the methodologies we are left with only a few possible explanations. One theory is that participants are deliberatly misreporting their preferences in personal interviews due to an element of social stigma. This phenomenon is also known as "shy Tory factor", "shy Trump-ers theory" or "Bradley effect". To examine the effects of this behaviour on opinion formation we studied the voter model on a 2d grid where agents were either neutral, moderate or extremist. Further we assumed that extremists may act like moderates or neutrals while interacting with agents of different opinion and compared the results with the undisturbed case.
