Ideological polarisation has drawn wide attention from both the general public and researchers. It is frequently argued that under the proliferation of ideological polarisation, echo chambers may be formed while people inside the echo chambers may be less willing to accept alternative political viewpoints and more likely to fall into fake news and online misinformation. To obtain more empirical evidence, we conducted an online experiment that explored the relationship between one's position in the political spectrum and his/her capabilities of identifying political misinformation, as well as the information consumption habits that may help identify online misinformation. While we statistically validated some information consumption habits that can help to identify political misinformation, it was unexpected that political extremists may be indeed more capable of identifying the validity of news and online information. Based on our findings, we also provided a range of theoretical and practical implications.

意识形态的两极分化引起了公众和研究人员的广泛关注。人们经常认为，在意识形态两极分化的扩散下，可能会形成回音室，而回音室中的人可能不太愿意接受其他政治观点，更容易陷入假新闻和网络错误信息。为了获得更多的实证证据，我们进行了一项在线实验，探讨了一个人在政治光谱中的位置与他/她识别政治错误信息的能力之间的关系，以及可能有助于识别在线错误信息的信息消费习惯。虽然我们统计验证了一些有助于识别政治错误信息的信息消费习惯，出乎意料的是，政治极端分子可能确实更有能力识别新闻和在线信息的有效性。根据我们的发现，我们还提供了一系列理论和实践意义。
