Amazon, Waterstones algorithms promote vaccine misinformation

A study (pdf) has found that Amazon is proactively recommending a wide range of anti-vaccination, health misinformation books, apparel and other products. 

Researchers at the University of Washington also found that Amazon's recommendation algorithms make matters worse by pushing users interested in these products at even more related products. 

Follow-up research in the UK by Sky News found that Foyles and Waterstones online bookstores are also recommending a wide range of COVID-19 anti-vaccination and health conspiracy theory books to their users. 

Amazon, Facebook, Google, Twitter and other companies are under pressure to tackle the huge volume of online misinformation about COVID-19.
