The vast majority of Jewish students around the world resort to hiding their Jewishness and support for Israel on university campuses to avoid becoming victims of antisemitism, according to a new survey conducted by the Anti-Defamation League (ADL) and the World Union of Jewish Students (WUJS).

A striking 78 percent of Jewish students have opted to “conceal” their religious affiliation “at least once” over the past year, the study found, with Jewish women being more likely than men to do so. Meanwhile, 81 percent of those surveyed hid their support for Zionism, a movement which promotes Jewish self-determination and the existence of the State of Israel, at least once over the past year.

Among all students, Orthodox Jews reported the highest rates of “different treatment,” with 41 percent saying that their peers employ alternative social norms in dealing with them.

“This survey exposes a devastating reality: Jewish students across the globe are being forced to hide fundamental aspects of their identity just to feel safe on campus,” ADL senior vice president of international affairs Marina Rosenberg said in a statement. “When over three-quarters of Jewish students feel they must conceal their religious and Zionist identity for their own safety, the situation is nothing short of dire. As the academic year begins, the data provides essential insights to guide university leadership in addressing this campus crisis head on.”

The survey said additionally that 34 percent of Jewish students reported knowing a Jewish peer whom someone “physically threatened on campus,” while 29 percent reported difficulties in attaining religious accommodations from their professors, confirming months of reports that Jewish students face both social and institutional discrimination at universities.

Tuesday’s survey comes amid a flood of data illustrating the severity of the campus antisemitism crisis.

Earlier this month, another survey commissioned by the ADL and the Academic Engagement Network (AEN) found that 73 percent of Jewish faculty witnessed their colleagues engaging in antisemitic activity, and a significant percentage named the Faculty and Staff for Justice in Palestine (FSJP) group as the force driving it.

Of those aware of an FSJP chapter on their campus, the vast majority of respondents reported that the chapter engaged in anti-Israel programming (77.2 percent), organized anti-Israel protests and demonstrations (79.4 percent), and endorsed anti-Israel divestment campaigns (84.8 percent).

Additionally, 50 percent of respondents said that anti-Zionist faculty have established de facto, or “shadow,” boycotts of Israel on campus even in the absence of formal declaration or recognition of one by the administration. Among those who reported the presence of such a boycott, 55 percent noted that departments avoid co-sponsoring events with Jewish or pro-Israel groups and 29.5 percent said this policy is also subtly enacted by sabotaging negotiations for partnerships with Israeli institutions. All the while, such faculty fostered an environment in which Jewish professors were “maligned, professionally isolated, and in severe cases, doxxed or harassed” as they assumed the right to determine for their Jewish colleagues what constitutes antisemitism.

Administrative officials responded inconsistently to antisemitic hatred, affording additional rationale to the downstream of hatred. More than half (53.1 percent) of respondents described their university’s response to incidents involving antisemitism or anti-Israel bias as “very” or “somewhat” unhelpful, and a striking 77.3 percent thought the same of their professional academic associations.

In total, alleged faculty misconduct and administrative dereliction combined to degrade the professional experiences of Jewish professors, as many reported “worsening mental and physical health, increased self-censorship, fear for personal safety,” and a sense that the destruction of their careers and reputations was imminent.

Higher education institutions in the US are showing some signs of recognizing the problem.

This week, administrators from across the US will amass in Washington, DC for a three-day symposium on combating campus antisemitism. Organized by AEN, which promotes academic freedom unfettered by boycotts and ideology, the event will be attended by administrators representing dozens of institutions such as Harvard University, Barnard College, and George Washington University, all of which have drawn scrutiny for responding to campus antisemitism in ways that critics — including Jewish community leaders and senior US officials — have described as insufficient if not dismissive.

Dozens of conversations and seminars will be held over the three-day event, with many being led by AEN faculty, as well as staff from the US Holocaust Memorial Museum and experts from the Jewish Federations of North America and the American Jewish Committee.

“College administrators are the ones tasked with recognizing and addressing antisemitism on campus, as well as setting the tone for behavioral expectations and campus culture,” Miriam Elman, executive director of AEN, said in a statement. “Today’s antisemitism, though, often takes forms that can be less familiar or harder to identify, making it all the more important to provide campus leaders with the tools, training, and support they need to recognize and respond effectively.”
