Expecting more from the BBC will only result in further disappointment. They know their audience and know that they can drop a word like science for immediate, unquestionable authority on the topic without having to provide substantial evidence.
This is why I bristle when people use that word these days. It's used as a trump card and as a way to castigate those who people disagree with politically (science deniers) without having to have a real conversation. Science is messy, contradictory, and constantly evolving and that's why true scientists love it! It is by no means something to stand blindly behind and to use as a baton against your enemies.
