From Wikipedia on R Furuli;
In a 2004 issue of Journal for the Study of the Old Testament, Lester L. Grabbe, professor of theology at the University of Hull, said of Furuli's study: "Once again we have an amateur who wants to rewrite scholarship. ... F. shows little evidence of having put his theories to the test with specialists in Mesopotamian astronomy and Persian history."[5]
Furuli here in the mental health analysis of JWs, is speaking outside of his expertise not that this automatically makes his information incorrect but his record shows that he is prepared to use his academic qualifications to promote his religion regardless of factual and peer recognized evidence.
With no further knowledge of his data on mental health, it would nevertheless be significant to point out that Furuli's first MA on Babylonian texts in 1995 coincided with the Watchtower's reappraisal of the failure of their pivotal "1914 generation" and the consequent 'excuse' of overlapping generations.
The Watchtower at that time would have been desperate to find an academic prepared to use "theocratic warfare" and support the unsupportable evidence for 607 bce as the fall of the siege of Jerusalem instead of 587 bce.
Clearly they found one in Furuli.
