Mission & Standards
The Hanover Institute for Public Policy informs the public about the inputs fueling antisemitism in the United States.
It documents what the evidence shows, and the methodology behind every figure, so that journalists, policymakers, educators, and the public can understand how antisemitism forms and spreads, going past incident counts to the narratives, tropes, and patterns behind them. The Institute is nonpartisan and nonadvocacy: its conclusions follow from the data, not from any political, organizational, or funder interest.
This discipline is a choice, not a coldness. For the people behind the Institute, the work is personal, and the conviction is that the most useful response to such a subject is neither fear nor resignation but careful measurement, and that the public, shown the evidence plainly, can be trusted to weigh it. The standards below are how that conviction is held to account.
The standard every report meets
Aggregates only
Every figure is a share, count, rate, or model score, and never a claim about an individual. The Institute does not profile or name a person.
Correlation, not causation
Where online activity relates to offline events, the Institute writes that the two coincided or were associated, never that one caused the other.
No moral valence
The Institute documents inputs and patterns. It does not frame any group as good or bad, and it assigns no blame.
Disclosed uncertainty
Confidence bounds, lower-bound flags, and preprint labels are carried into the findings. What is undetermined is stated, not hidden.
Sourced and reproducible
Every figure traces to a study aggregate or a named peer-reviewed or primary source, and every report ships the methodology behind its numbers.
No advocacy
The Institute presents what the evidence shows. It takes no policy positions, makes no recommendations, and endorses no party or cause.
