It could be argued that it is impossible to be totally value-neutral (unbiased). As such the best that can be hoped for is that perspectives/bias be recognised.
Even significantly biased data may still be useful as long as you recognise the bias. You may need to look for resources with differing bias to get a balanced picture.
