A common approach to make scientific information more accessible for the broader public, is making it easier to understand and translating it into more appealing formats, like short and entertaining online videos. However, simplifying scientific content can have negative impact on consumers, as it can lead to the so-called easiness effect, a cognitive bias which can include an overestimation of one's own competencies. In the context of scientific studies, this bias has previously only been demonstrated by comparing text-based scientific abstracts with easier-to-understand plain language summaries (PLS). With several unsuccessful approaches in research to reduce the easiness effect, a promising new method might be using debiasing videos as they have been shown to reduce cognitive biases in other contexts. The present study expands the research by exploring the easiness effect in animated video abstracts and investigates whether a debiasing video can reduce it.
This experiment realized a 2 (video abstract type: PLS versus scientific abstracts) × 2 (debiasing video: shown versus not shown) between-participants design. Overall, 179 participants received four abstracts and rated (1) study comprehensibility, (2) perceived study credibility, (3) confidence in one's ability to evaluate the study, and (4) perceived ability to make decisions without further information. Also, intended consumer reactions (knowledge-enhancing and social media reactions) were collected.
Animated PLS, compared to animated scientific abstracts, actually enhanced comprehensibility of scientific content. This effect was accompanied by a significant easiness effect, as PLS were perceived as more credible and they produced a higher confidence in the recipients' perceived ability to evaluate the study. No differences in consumer reactions were observed between abstract types. Also, the video-based debiasing intervention did not affect study evaluation.
The easiness effect can be reliably generated in video abstracts and it is very robust, as it persists even if a debiasing intervention is carried out beforehand. This study underscores the need for responsible communication strategies in science popularization and shifts the focus to the increasingly popular video abstracts. The results provide a valuable starting point for further research on how video-based science communication can be optimized to convey scientific information effectively.
让科学信息更易于广大公众获取的一种常见方法,是使其更易于理解并转化为更具吸引力的形式,比如简短且有趣的在线视频。然而,简化科学内容可能会对受众产生负面影响,因为这可能导致所谓的简易效应,这是一种认知偏差,可能包括对自身能力的高估。在科学研究的背景下,此前这种偏差仅通过将基于文本的科学摘要与更易理解的通俗易懂的语言摘要(PLS)进行比较得以证明。由于在研究中减少简易效应的几种方法都未成功,一种有前景的新方法可能是使用去偏视频,因为在其他情境中已证明其能减少认知偏差。本研究通过探索动画视频摘要中的简易效应并调查去偏视频是否能减少该效应,扩展了这一研究。
本实验采用了被试间设计,即2(视频摘要类型:通俗易懂的语言摘要与科学摘要)×2(去偏视频:展示与未展示)。总体而言,179名参与者收到了四篇摘要,并对以下内容进行评分:(1)研究的可理解性,(2)对研究可信度的感知,(3)对自身评估研究能力的信心,以及(4)在没有更多信息的情况下做出决策的感知能力。此外,还收集了预期的受众反应(知识增强和社交媒体反应)。
与动画科学摘要相比,动画通俗易懂的语言摘要实际上提高了科学内容的可理解性。这种效应伴随着显著的简易效应,因为通俗易懂的语言摘要被认为更可信,并且它们使受众对自身评估研究的能力产生了更高的信心。在摘要类型之间未观察到受众反应的差异。此外,基于视频的去偏干预并未影响对研究的评估。
简易效应在视频摘要中能够可靠地产生,并且非常稳固,因为即使事先进行了去偏干预,它仍然存在。本研究强调了在科学普及中采用负责任的传播策略的必要性,并将重点转移到日益流行的视频摘要上。研究结果为进一步研究如何优化基于视频的科学传播以有效传达科学信息提供了有价值的起点。
