reddit 與 4chan 在新聞網路上的獨特性

在「Study finds fringe communities on Reddit and 4chan have high influence on flow of alternative news to Twitter」這邊看到的:

After analyzing millions of posts containing mainstream and alternative news shared on Twitter, Reddit and 4chan, Jeremy Blackburn, Ph.D., and collaborators found that alt-right communities within 4chan, an image-based discussion forum where users are anonymous, and Reddit, a social news aggregator where users vote up or down on posts, have a surprisingly large influence on Twitter.

依照對 reddit4chan 的描述,這兩個媒體對 Twitter 的影響,會讓我聯想到在台灣 Ptt 對各新聞媒體的影響:Ptt 是很多新聞的起點?

"Based on our findings, these smaller, fringe communities on Reddit and 4chan serve as an incubation chamber for a lot of information," said Blackburn, assistant professor of computer science in the UAB College of Arts and Sciences. "The content and talking points are refined until they finally break free and make it to larger, more mainstream communities."

真的研究應該可以看出 Ptt 的影響力?


應該是前陣子被 Nuzzel 推薦 2015 八月的老新聞,這個研究在 Nature 上發表:「Over half of psychology studies fail reproducibility test」。

這個研究重複了 98 篇原創研究來重新實驗:

In the biggest project of its kind, Brian Nosek, a social psychologist and head of the Center for Open Science in Charlottesville, Virginia, and 269 co-authors repeated work reported in 98 original papers from three psychology journals, to see if they independently came up with the same results.

結果在 100 次的實驗 (其中有 2 個是重複的) 發現只有 39 個實驗結果被重製出來:

According to the replicators' qualitative assessments, as previously reported by Nature, only 39 of the 100 replication attempts were successful. (There were 100 completed replication attempts on the 98 papers, as in two cases replication efforts were duplicated by separate teams.)
