信息爆炸和信息不确定语境下的可信度判据研究--以COVID-19疫情为例

Study on the Criteria of Information Credibility in the Context of Information Explosion and Uncertainty:The Case of COVID-19

在突发事件中,信息数量的爆炸式增长伴随着不确定性的急剧上升,显著提升了公众对信息可信度判断的困难程度。本研究以COVID-19疫情为例,探讨了信息爆炸和信息不确定语境下用户信息可信度的判据。本研究采用扎根理论方法,通过访谈提纲设计和理论抽样,对21名研究对象进行了深度访谈;对原始语料初步整理后进行开放编码、主轴编码、选择编码以及理论饱和度检验;发掘出了包括权威性、可靠性、内部质量、传播特征和积极性5个主范畴,以及相应的12个范畴和35个初始概念等在内的信息可信度判据;对专业性等普适判据,以及积极性等新发现的判据进行了深入的剖析与探讨。

The considerable increase in the amount of information along with high uncertainty in unexpected emergencies result in a challenge for the public to assess information credibility.This study takes COVID-19 as an example and explores the criteria of information credibility in the context of information explosion and uncertainty.Guided by the grounded theory approach,we developed an interview protocol and conducted theoretical sampling,including 21 participants.After sorting out the original materials,we conducted open coding,axial coding,and saturation test.Further,we found six core categories(i.e.,authority,reliability,internal soundness,communication characteristics,and positivity)together with 12 corresponding categories and 35 concepts,which consist of the criteria of information credibility.Finally,we discussed several general criteria(e.g.,expertise)among different contexts and interpreted some new criteria(e.g.,positivity)in the current context.
