The BPS Research Digest (29 Mar) highlights a study that indicates that courtroom confidence backfires when a witness makes an error:

Confidence is extremely convincing – many studies have shown that both real jurors and mock jurors are more likely to believe a courtroom witness who appears confident. But what if a confident witness is seen to make an error? New research by Elizabeth Tenney and colleagues shows that in this case, confidence backfires: confident witnesses who make mistakes are perceived to be the least reliable of all.

The press release announcing this study is here.

The Situationist (29 Mar) comments on recent research that links violence and religious indoctrination, and points to other research on religious messages and violence:

New technologies are to be used to boost police detection rates while DNA samples are to be taken from any crime suspect who comes into contact with the police.
