If you read an article about a controversial issue, do you think you’d realise if it had changed your beliefs?
No one knows your own mind like you do – it seems obvious that you would know if your beliefs had shifted. And yet a new paper in The Quarterly Journal of Experimental Psychology suggests that we actually have very poor “metacognitive awareness” of our own belief change, meaning that we will tend to underestimate how much we’ve been swayed by a convincing article.
The researchers Michael Wolfe and Todd Williams at Grand Valley State University said their findings could have implications for the public communication of science. “People may be less willing to meaningfully consider belief inconsistent material if they feel that their beliefs are unlikely to change as a consequence,” they wrote.
The researchers recruited over two hundred undergrads across two studies and focused on their beliefs about whether the spanking/smacking of kids is an effective form of discipline. The researchers chose this topic deliberately in the hope the students would be mostly unaware of the relevant research literature, and that they would express a varied range of relatively uncommitted initial beliefs.
