補充實驗二

此實驗的小眾媒體設定是利用減低的連結數量來設定小眾媒體，和大眾媒體 相比，在實驗中我們設定小眾媒體的連結數量約為大眾媒體的十分之一，並依此 設定進行了小眾媒體數量為 10、30、50，報導偏向為 0、0.1、0.2、0.3，0.4 的 實驗。

固定小眾媒體數量為 10、30、50 的實驗結果分別為圖表 20、21、22，如同 大眾媒體實驗所得到的結果，小眾媒體若增加了偏頗報導的程度，意見群聚度、

意見極化程度與社會極化程度也會隨之提高。

圖表 23 表示了固定的媒體偏頗程度設定時，不同小眾媒體數量的比較，與之 前大眾媒體的實驗結果比較﹝圖表 15、19﹞，社會極化程度並沒有明顯的上升 傾向。這應該是因為這時候的社會極化程度已經來到了高點，才表現不出明顯的 傾向。

綜合以上的實驗結果，延長的互動回合數並不改變原有的觀察結果，小眾媒 體也表現出與大眾媒體一致的傾向。
