Is There Evidence That Mindfulness Can Help?

There's something about what happens in the relationship tothe object when the the designator of the word mine, is connected to it. And i'm and i've wondered how much er there is in the way of empirical evidence that maybe mindfulness, meditation could help a road some of these cognitove biases. Have you heard of any one describing a cognivios evaluation, or a cognibios test wort? I'm not aware of one, and i can imagine that it would be kind of hard to construct.
