Vidino's work has received a mix of acclaim and criticism.
John Jenkins, who in 2014 led the UK government review of the Muslim Brotherhood, said that "Lorenzo Vidino is a distinguished scholar of the Muslim Brotherhood. In
The Closed Circle, he provides the invaluable service of letting those who have left the movement speak for themselves. What they say should enlighten and alarm anyone who thinks the Brotherhood is moderate, a firewall against extremism, or genuinely committed to democratic pluralism. Policy makers need to read it—and then read it again." American journalist
Graeme Wood said that "Vidino's interviews reveal a patient organization that markets itself as moderate but sometimes acts like a sinister and dangerous cult. The Brotherhood requires subtle analysis, and Vidino provides just that—neither overstating its threat nor accepting its claims to be a benign fraternal order. An essential contribution to our understanding of Islamism in the West." Islamic scholar Reinhard Schulze, a professor at the
university of Bern, has repeatedly criticized Vidino on Twitter: "In the controversy about the Muslim Brotherhood, much is reminiscent of radical conspiracy-theoretical submissions with which Freemasons, socialists, and communists were fought in the 19th century. Lorenzo Vidino wraps them here in a pseudo-scientific garment in order to 'prove' that a small 'leadership clique' (30 people) is acting 'underground' to destabilize Central European society and to disseminate 'background content for assassins'. He sees the Muslim Brotherhood as a secret society that wants to infiltrate not only Islam but the West in general. Such absurd allegations obscure politicians' view of the problems associated with the crisis caused by religious disintegration. A policy that seeks to counteract this disintegration does not need heavily right-wing stereotypical conspiracy theories but rather a broad civil society alliance of both Muslim and non-Muslim institutions and personalities that helps counteract religious disintegration through targeted programs". In April 2020, the Bridge Initiative of
Georgetown University published a comprehensive fact sheet about Vidino, claiming that his "research promotes conspiracy theories about the Muslim Brotherhood in Europe and the United States". In the tweet, Tazamal referred to the Austrian government's use of Vidino's work to justify
Operation Luxor, the largest police operation in Austria since 1945 (later declared "unlawful" by the courts), which raided the homes of nearly seventy families active in Austrian Muslim associations, including
Farid Hafez, a professor at
Salzburg and Georgetown who researches and publishes on
Islamophobia. In response to criticism, Vidino stated in a September 2022 interview with
Wiener Zeitung: "If my work is flawed and has caused you damage, why don't you sue me? It's just general criticism, personal attacks and empty legal threats; that's quite revealing to me." Anas Schakfeh, former president of the Islamic Religious Community in Austria, commented that "U.S. residents can hardly be sued in Austria". In addition, he asked whether "not being sued proves the claim wrong". Muslim Youth Austria (MJÖ) refrained from filing a lawsuit because Vidino resides in the US, and thus a lawsuit in Austria is "practically impossible". In addition, MJÖ cited a decision of the
Higher Regional Court of Graz, in which it is stated that the "assessment in the Scholz/Heinisch expert opinion, which is based, among other things, on the Vidino study and afterthoughts, is inadequate as evidence". According to Thijl Sunier, professor at the
Free University of Amsterdam, although Vidino claims to be an independent scholar, leaked documents show that he was paid by a private intelligence service to scientifically substantiate allegations against the Muslim Brotherhood. Furthermore, he is associated with a camp that spreads conspiracy theories about the Brotherhood. To anthropologist and
University of Toronto professor
Amira Mittermaier, Vidino is a proponent of the
Great Replacement conspiracy theory, which claims that Muslims are set to displace the white population in the
Global North. She criticizes Vidino's argument—that the Muslim Brotherhood promotes a victim narrative—as a striking example of "rhetorical gymnastics". ==Publications==
