 A comprehensive three-year study (2009–2012), regarded by its researchers as 'the most definitive and balanced study to date on the topic', found that incitement, demonization or negative depictions of the other in children's education was "extremely rare" in both Israeli and Palestinian school texts, with only 6 instances discovered in over 9,964 pages of Palestinian textbooks, none of which consisted of "general dehumanising characterisations of personal traits of Jews or Israelis".Israeli officials rejected the study as biased, while Palestinian Authority officials claimed it vindicated their view that their textbooks are as fair and balanced as Israel's.Textbooks in Israel also have been studied and some problems found.
