網路使得人際溝通更加迅速與便捷，相對地也讓謠言的擴散威力更為驚人。模因（meme）為探討謠言傳播的一項重要理論，透過訊息複製、變異及選擇的過程使謠言不脛而走。本研究將模因應用至網路平台，以眾所矚目的社會事件洪仲丘案為例，採用實證問卷調查方法，檢視新聞事件發展時網民對相關訊息接收、複製調整、再傳遞的傳播模式，並聚焦於訊息篩選機制與複製擴散的傳播特性。研究結果發現，網民雖表示會評估訊息可信度，但面對謠言終究未能有效區辨，而網路回應的易完成性強化各種再傳遞行為的效果，使得謠言迅速擴散造成廣泛流傳的現象。

The network accelerates interpersonal communications, but it also widens rumor circulation with high efficiency.

Also, the network enhances online behavior in coping, varying, selecting, disseminating information and greatly facilitating the spread of the rumors, given its characteristic of respond-easy with completing friendly.
