A turning point came in the 1950s when Benjamin Klar discovered that an anti-Karaite polemical poem by R. Sa‘adiah Gaon criticized a Karaite masorete by the name of “Ben Asher”. This fits very well with Sa‘adiah's rejection of ben Asher in favor of ben Naftali, as well the fact that, ben Asher nevertheless became accepted as relations between the Karaites and Rabbanites improved. Aron Dotan has dealt with many of the arguments, including Klar's, and also argued that the approval of Maimonides is evidence against the claim. However, according to Zer, few researchers have expressed their support for Dotan’s position.
