As part of the article, the author presents the advantages and disadvantages of research solutions used during the presidential election in 2010. The decision to choose these elections as an example was dictated, on the one hand, by the fact that the survey on the day of the election was carried out by three companies, and on the other hand, by the fact that different research techniques were used. Moreover, the conducted research is well documented both in the journalism and in the report of Professor Domański’s team, and by the author himself, who analyzed this problem in terms of the selection of an appropriate research technique earlier.
