Some examples of reliable resources are for instance Peer reviewed journals], where all the
published information has been reviewed and criticised by other experts in the field before
the information is published. However, even peer reviewed journals cannot guarantee 100%
reliability, because they might tend to support points of view which are well-established,
and evidence for new ideas or different viewpoints can be overlooked.
Information from websites, blogs and also newspaper or magazine articles should be treated
with caution, as this is much less likely to have been peer reviewed. You should ask yourself,
are there comments on the website and if so what is the quality of the comments? Do they
agree or disagree? What might be the motivations of the authors, and the people making
the comments?
When evaluating evidence in a written piece of text such as in articles or books, you will be
able to find a reference for each given source of evidence.
