In this article, we present a type of media disorder which we call ‘junk news bubbles’ and which derives from the effort invested by online platforms and their users to identify and circulate contents with rising popularity. Such emphasis on trending matters, we claim, can have two detrimental effects on public debates: first, it shortens the amount of time available to discuss each matter and second, it increases the ephemeral concentration of media attention. We provide a formal description of the dynamic of junk news bubbles, through a mathematical exploration of the famous ‘public arenas model’ developed by Hilgartner and Bosk in 1988. Our objective is to describe the dynamics of the junk news bubbles as precisely as possible to facilitate its further investigation with empirical data.

在本文中，我们介绍了一种称为“垃圾新闻泡泡”的媒体失调，它是由在线平台及其用户投入大量精力来识别和传播日益流行的内容而产生的。我们声称，对趋势性问题的这种强调会对公众辩论产生两个不利影响：首先，它缩短了讨论每个问题的时间，其次，它增加了媒体关注的短暂集中。我们通过数学研究Hilgartner和Bosk于1988年开发的著名的“公共场所模型”，来正式描述垃圾新闻气泡的动态。我们的目标是尽可能准确地描述垃圾新闻气泡的动态，以达到以下目的：借助经验数据促进其进一步研究。
