Our newspaper, Washington, June 2 (Reporter Wang Youran) A new US study found，The "bet365 score" does not only have dangerous consequences as people often think。If used properly，The "bet365 score" can also provide a good idea for exploring deliberative democracy。

Some theories about political polarization，On issues involving political leanings，The exchange of bet365 score will only deepen the existing beliefs of those holding different positions，Because people tend to look for bet365 score that is consistent with their existing ideas rather than contrary to them。This will lead to similar ideas being repeatedly spread and reinforced within a closed system，The so-called "echo chamber effect" occurs。The Proceedings of the National Academy of Sciences recently published online the paper "The Wisdom of Partisan Groups" co-authored by researchers such as Joshua Becker from the Kellogg School of Management at Northwestern University. crowds)，The “echo chamber effect” verified。

To verify whether the "bet365 score" will inevitably exacerbate political divisions，Becker et al. conducted a set of experiments。Researchers divided participants into groups based on party affiliation，And asked them several factual questions involving political leanings，How the U.S. unemployment rate changed during the Obama administration，How the number of illegal immigrants in the United States has changed in the past 10 years, etc.。Participant after answering questions，You can communicate with each other and modify your answers。

Experiment results display，After participants communicated with each other, the accuracy of the answers submitted increased by 35% compared with the original。After exchanging information，Not only were their answers closer to those of participants from the same party，Also closer to opposing party participants。When there is only intra-group communication but no cross-group communication，The experimental results are also the same。This shows that bet365 score influence among members of the same group improves their accuracy in judging objective facts，Reduced political polarization。However，The driving force for participants in this experiment to process bet365 score information was to be as accurate as possible (close to actual data)，If the question asked by the researcher is a non-factual question involving political leanings，Whether the positions of the participants will become more neutral after exchanging information，It needs to be confirmed by experiments。
