Freya Wikipedia is a reliable source on a lot of subjects, but like any source, whether online, on paper, or even papyrusor written on stone, you need to look at the source and make a reasonable attempt to assess its, validity. It is called 'Fact checking'
If I look up the Victorian author 'Mrs Oliphant' I can be reasonably certain the information contained in her profile is accurate, partly because i know something about her life, but also, because she is not an object of general interest and is not controversial in any way.
Were I looking up someone political 'Nigel Farage', for example. I know that his profile could be written by someone who hero worshiped him or who holds him in cocntempt or is deliberately subvesive, so I would look at the profile but very thoroughly fact check it.
There is nothing new in this. My personal research interests sometimes find me reading the Domesday Book, or Anglo-Saxon Chronicles and one has to bring the same critical faculty to them as well, asking who is writing them, why, what message were they wanting to convey, how accurate are the contents.
Nothing changes
