Tưởng vậy mà không phải

There is a new and very interesting paper on this topic by Annie Y. Chen, Brendan Nyhan, Jason Reifler, Ronald E. Robertson and Christo Wilson. Here is the abstract:

Do online platforms (nền tảng trực tuyến) facilitate (tạo điều kiện thuận lợi) the consumption (tiêu thụ) of potentially harmful content? Despite widespread concerns that YouTube’s algorithms (thuật toán) send people down “rabbit holes” (hang thỏ) with recommendations (gợi ý) to extremist (cực đoan, quá khích) videos, little systematic evidence (bằng chứng có hệ thống) exists to support this conjecture (sự phỏng đoán). Using paired behavioral and survey data provided by participants recruited from a representative sample (n=1,181), we show that exposure to alternative and extremist channel videos on YouTube is heavily concentrated among a small group of people with high prior levels of gender and racial resentment. These viewers typically subscribe (đăng ký) to these channels (causing YouTube to recommend their videos more often) and often follow external links to them. Contrary to the “rabbit holes” narrative, non-subscribers are rarely recommended videos from alternative and extremist channels and seldom follow such recommendations when offered.
