An important aspect of the study's findings for Jäncke is that they reflect the great developments made in the field in recent years: "Just 30 years ago we thought that the human brain had few or no individual characteristics. Personal identification through brain anatomical characteristics was unimaginable." In the meantime magnetic resonance imaging has got much better, as has the software used to evaluate digitalized brain scans -- Jäncke says it is thanks to this progress that we now know better.Ratshit. The individuality of brains has been known pretty much forever. 30 seconds in Googlebooks finds this 1919 textbook on 'Brightness and Dullness in Children'. At page 90 of the PDF:
Bolton believes that differences in the intelligence of normal individuals are due to variation in the same cortical features as those by which feeble-mindedness is so clearly shown. “As a final remark,” he writes, “I would add that there is reason to believe that this physical basis of the cerebral functions . . . exhibits equally important though less extensive variations in the cases of presumably normal individuals; and thus indicates the likelihood of a structural origin for individual differences in mental endowment.”"If "we" thought that brains were identical, it was because "we" were rigidly orthodox adherents of fashionable bizarre delusions that were mandatory in academia after WW2. (Good old 1946.) Some parts of "we" have recovered from this form of dementia, though the recovered folks are still viewed with suspicion in academia.
