Evaluating Sources - Bias & Credibility

Tool to evaluate academic journals - Beall's List

"This is a list of questionable, scholarly open-access publishers. We recommend that scholars read the available reviews, assessments and descriptions provided here, and then decide for themselves whether they want to submit articles, serve as editors or on editorial boards. In a few cases, non-open access publishers whose practices match those of predatory publishers have been added to the list as well. The criteria for determining predatory publishers are here.​"

Games and Simulations


Bad News

In Bad News, you take on the role of a fake news-monger. Drop all pretense of ethics and choose a path that builds your persona as an unscrupulous media magnate. But keep an eye on your ‘followers’ and ‘credibility’ meters. Your task is to get as many followers as you can while slowly building up fake credibility as a news site. But watch out: you lose if you tell obvious lies or disappoint your supporters!
