信息获取的范式:社会媒体诱导极化模型研究

The Paradox of Information Access: On Modeling Social-Media-Induced Polarization

摘要:

本文开发了一个随机模型的漂移在人类的信念,表明今天的绝对量的可访问的信息,结合消费者的确认偏见和自然偏好更外围的内容,必然会导致两极分化增加。这个模型解释了在分享增加的时代,意识形态日益分裂的悖论。由于社交媒体、搜索引擎和其他实时信息共享渠道声称促进对信息的访问,因此由于随之而来的信息过载而产生了对内容过滤的需要。一般来说,消费者会选择与其个人观点和价值观相匹配的信息。这种选择中固有的偏见与当今的信息策展服务相呼应,这些服务通过根据观察到的消费者偏好过滤新内容来最大化用户参与度。因此,个人接触到的意识形态范围越来越窄,从而使社会分裂成意识形态上越来越孤立的飞地。我们称之为信息获取的悖论。该模型还表明,只要注入少量定位良好的错误信息,就可以造成不成比例的损害。本文介绍了建模方法,并评估不同的人口规模和参数设置的建模结果。

英文摘要:

The paper develops a stochastic model of drift in human beliefs that shows that today's sheer volume of accessible information, combined with consumers' confirmation bias and natural preference to more outlying content, necessarily lead to increased polarization. The model explains the paradox of growing ideological fragmentation in the age of increased sharing. As social media, search engines, and other real-time information sharing outlets purport to facilitate access to information, a need for content filtering arises due to the ensuing information overload. In general, consumers select information that matches their individual views and values. The bias inherent in such selection is echoed by today's information curation services that maximize user engagement by filtering new content in accordance with observed consumer preferences. Consequently, individuals get exposed to increasingly narrower bands of the ideology spectrum, thus fragmenting society into increasingly ideologically isolated enclaves. We call this dynamic the paradox of information access. The model also suggests the disproportionate damage attainable with a small infusion of well-positioned misinformation. The paper describes the modeling methodology, and evaluates modeling results for different population sizes and parameter settings.
