Referencing
Historically information was scarce, but now, due to the internet information is in overabundance and it's difficult to know what to trust. Wikipedia has tried to combat this issue, by listing which sources are most reliable and excluding those which prefer clicks over fact:
However, the word reliable simply implies sources are not making things up. Reliability of factual accuracy does not take into account the potential biases of each source or framing of issues to make it more digestible to specific consumers. So for fact, we need to look at the scientific literature, which should be able to deduct framing and bias to get at the root of an issue.
Scientific Bias
Unfortunately, although scientists try to remove bias, it is never perfect. This is mainly because the majority of independent scientists publish scientific papers via journals. The majority of these journals are owned by a few private corporations (See Figure 3) which can reject or accept the articles based upon their own interests. This may be the root cause of something called the replication crisis, which is the fact that the majority of scientific findings published in journals cannot be reproduced by another scientist.
So whilst scientific information may be more rigorous than popular media, it is still subject to bias. To overcome this BurnZero has adopted a critical analysis weighting system which gives preference to sources which are thought to contain less bias relative to others.
