jensen is particularly notable article because of the social controversy it generated at the time not because of presentation of scientific arguments which are presented much better in later reviews which includes later reviews the same would apply to say the mismeasure of man such famous sources should be mentioned but since there are thousands of studies we cannot name them all furthermore picking out which one we feel should be included is problematic which is why review articles are preferable if available again i repeat that general reader is likely not all that interested in the complex and often mathematical details of the debate so i think the genetic or not not debate should be summarized very briefly
