Clearly, if meta-analyses are to be taken seriously, they need to be conducted carefully and objectively. In support of the anti-Dodo bird side, Hunsley (2007) says that when "measurement quality is controlled for and when treatments are appropriately categorized, there is consistent evidence in both treatment outcome and comparative treatment research that cognitive and behavioral treatments are superior to other treatments for a wide range of conditions, in both adult and child samples." This suggests that if and when variables are controlled, there is appreciable evidence for the superiority of cognitive and behavioral treatments.
