| Summary: | Kruijt and Carlbring misrepresent the position conveyed in our commentary,1 wrongly attributing to us the suggestion ‘that we should only call CBM CBM if it is successful’. Our actual points are: (a) it cannot be claimed that cognitive bias has been modified when assessment data reveal that no modification of cognitive bias has taken place; and (b) the emotional impact of modifying cognitive bias cannot be determined from studies that fail to modify cognitive bias. Also, incorrectly, they describe our commentary as an ‘exposé on the correct question to metaanalyse’. We highlight the need to distinguish two quite different questions, without claiming that either is ‘correct’, and emphasise the resulting problems when meta-analyses fail to do so.
