Analysis / Bias
In review, Medium has a variety of writers from many different political perspectives. Therefore, the only way to check for bias is by sampling a variety of recently published articles. We chose the politics category as our gauge for bias. We sampled 25 top stories in their political section and found that 19 out of 25 or 76% leaned left. That doesn’t mean it represents the entirety of the site, but does indicate that more stories come from a left leaning perspective. We also searched for stories that promote conspiracy theories and pseudoscience. We found most were scientifically sound, however their were some that presented anti-vaccination and GMO positions as well as human influenced climate change denial, geoengineering via chemtrails and false flag operations. Lastly, because Medium publishes a wide variety of sources, there are times that they fail fact checks. Again, this is not Medium’s fault. They simply are the “medium” for a variety of sources, some of which may not be factual.
In general, Medium provides a mixed bag of stories that lean left, with some that lack evidence and sourcing.
Overall, we rate Medium Left-Center biased based on story selection that moderately favors the left and Mixed for factual reporting due to a lack of sourcing and some articles that promote conspiracy theories and pseudoscience. (5/14/2016) Updated (D. Van Zandt 9/26/2019)
