Due to the pandemic of coronavirus, the most source that the people depend on was social media. There is no guaranteed solution that is biased from political opinion.
An example of that the conflict between left and right in the USA the left believes in lockdown first and the right believes lockdown must be the last reserve. each party has scientists on their side.
Another issue in my opinion if we want to restrict sources on experts. what is an expert? What are the criteria? who chose the criteria? what are the qualifications? and who chose the qualifications?
Finally, what are the other biases in the healthcare resources such as information and instruction for coronavirus?
