人机传播视域下算法新闻可信度的感知研究——基于一项对大学生的控制实验分析
Analysis on Perceived Credibility of Algorithmic News From Perspective of the Human-Machine Communication——Based on a control experiment on College Students
本文在人机传播的视域下,采用控制实验法,通过比较的方式探讨了受试者对算法新闻可信度的感知。研究发现:受试者对署名作者为算法的新闻可信度的感知值要显著高于署名为人类记者的新闻可信度的感知值,这种差异集中体现在受试者对不同署名新闻所含的“偏见”的感知上;期望确证理论不能解释这一差异,因为实验中受试者对算法新闻的期待值更高而非更低;相对于单独署名为人类记者的新闻而言,人机共同署名并不能有效提升受试者对新闻的可信度感知;新闻主题会影响到受试者对新闻可信度的感知,在署名相同的情况下,社会新闻被感知到的可信度更低。最后,本文在人机传播的意义上进行了讨论。
The perceived credibility of algorithmic news was investigated from perspective of human machine communication by applying control experiment method. Here were the findings. Firstly, the news attributed to algorithm author were perceived more significantly credible than the news attributed to the human journalist, which was resulted from subjects’ different perception on the bias of the news with different authorship. Secondly, the credibility difference was not explained by Expectation-Confirmation Theory, because the subjects` expectation of algorithmic news was higher. Thirdly, compared with the news attributed to human reporters alone, the news attributed to man-machine co-author can not effectively improve the subjects' perception of the credibility of the news. Fourth, news topic affected the subjects' perception of news credibility. When the authors were the same, the perceived credibility of social news was lower. At last, the implication of the findings was discussed in the field of Human-Machine Communication.

We conducted an online experiment to study people’s perception of automated computer-written news. Using a 2 × 2 × 2 design, we varied the article topic (sports, finance; within-subjects) and both the articles’ actual and declared source (human-written, computer-written; between-subjects). Nine hundred eighty-six subjects rated two articles on credibility, readability, and journalistic expertise. Varying the declared source had small but consistent effects: subjects rated articles declared as human written always more favorably, regardless of the actual source. Varying the actual source had larger effects: subjects rated computer-written articles as more credible and higher in journalistic expertise but less readable. Across topics, subjects’ perceptions did not differ. The results provide conservative estimates for the favorability of computer-written news, which will further increase over time and endorse prior calls for establishing ethics of computer-written news.

Artificial intelligence (AI) and people’s interactions with it—through virtual agents, socialbots, and language-generation software—do not fit neatly into paradigms of communication theory that have long focused on human–human communication. To address this disconnect between communication theory and emerging technology, this article provides a starting point for articulating the differences between communicative AI and previous technologies and introduces a theoretical basis for navigating these conditions in the form of scholarship within human–machine communication (HMC). Drawing on an HMC framework, we outline a research agenda built around three key aspects of communicative AI technologies: (1) the functional dimensions through which people make sense of these devices and applications as communicators, (2) the relational dynamics through which people associate with these technologies and, in turn, relate to themselves and others, and (3) the metaphysical implications called up by blurring ontological boundaries surrounding what constitutes human, machine, and communication.

In this article, we argue that journalism studies, and particularly research focused on automated journalism, has much to learn from Human-Machine Communication (HMC), an emerging conceptual framework and empirically grounded research domain that has formed in response to the growing number of technologies-such as chatbots, sodas bots, and other communicative agents enabled by developments in artificial intelligence (AI)-that are designed to function as message sources, rather than as message channels. While the underlying, but often unquestioned, theoretical assumption in most communication research is that humans are communicators and machines are mediators, within HMC this assumption is challenged by asking what happens when a machine steps into this formerly human role. More than merely a semantic move, this theoretical reorientation opens up new questions about who or what constitutes a communicator, how social relationships are established through exchange among humans and machines, and what the resulting implications may be for self, society, and communication. In the particular case of automated journalism-in which software assumes a news-writing role that has long been considered a distinctly central, and indeed human, element of journalism-the introduction of HMC offers a generative starting point for theory development, advancing our understanding of humans, machines, and news for an oncoming era of AI technologies.

Although credibility is a complicated construct involving interrelationships among messenger, message, communication channels, and recipients, the most widely used credibility indexes seek to measure only one of those attributes at a time. This study used two widely used credibility scales to simultaneously measure message and messenger credibility. An analysis showed high correlations between the two scales and among their individual variables but still distinguished differences between messenger and message.

1. 实验者在校园里张贴招募广告,邀请大学生自愿参加实验,并承诺每位受试者在结束实验后可以获得一定报酬。广告的主要内容为“我们正在从事一项关于新媒体的研究,需要招募大学生作为受试者”,广告对实验内容只是进行了非常概括的描述,以避免受试者知道实验的具体内容和实验目标而影响实验结论,同时也可避免只对算法新闻感兴趣的大学生来应聘参加实验的情况。
2. 由于新闻B原文篇幅较长,实验者对其进行了缩减以适合本实验。
