What Neil Tyson Degrasse has to say about Wikipedia sums it up nicely, I don't particularly care for the man (hes a notorious egotist and self promoter). What he has to say in the video rings really true of why Wikipedia shouldn't be trusted even when it comes to even things like basic facts coming from an expert because of the sheer amount of labeling, counterlabeling, claiming and just bias that its system of governance allows.  Not a bad starting point but just do not trust any of it at all unless you read the source material yourself.
