A tiny people with a giant story

First, a guess. Don’t look anything up.

Guess: what percent of all the people on Earth are Jewish?

1 Drag the slider (or tap − and +) to your guess.2Tap Lock in my guess.

10%
Each dot below stands for 1 of 1,000 people.

Your guess will fill the dots in yellow, starting from the top left. Then the real answer will show up in blue.

There are about 16 million Jews in a world of 8 billion people. If the world were a stadium of 1,000 people, about 2 would be Jewish.

Hold on to that number. The lie you’re about to study depends on people imagining Jews as huge, everywhere, and secretly in charge.

So what kind of group are Jews?

Pick the answer you think fits best.

Empire after empire

Blue tiles are the times Jews ruled themselves. In between, era after era, a new empire took the land.

or tap any tile

    How small is 16 million?

    Three ways to count. Jews are a people first, so start there.

    How Jewish is each place?Even in New York, Jews are about 1 in 9. Only one country has a Jewish majority.

    About 7 in 10 people in Israel today are Jewish, with roots in the Middle East, North Africa, Europe, Ethiopia and beyond. About 1 in 5 is Arab, and most Arabs in Israel are citizens who can vote.

    Jews: Sergio DellaPergola, 2025 (world, United States) · UJA-Federation of New York, 2023 (a broader, self-identified count) · Israel Central Bureau of Statistics, end of 2025 · Populations: UN 2024, US Census Bureau 2025

    16 million, to scaleAll the Jews on Earth, next to a city, a country and some other peoples. Jews are counted worldwide; most other peoples here are counted only at home, so the real gaps are even bigger.

    Jews: Sergio DellaPergola, 2024–25 · Tokyo: UN, 2025 · United States: US Census Bureau, 2025 · Han Chinese: China census 2020 · Bengalis: Bangladesh census 2022 and India census 2011 · Japanese: Japan census 2025 · Koreans: South Korea 2020 census, UN 2024 estimate for North Korea, Overseas Koreans Agency 2024

    How big was each country’s main people? (1990s)Israel is often called an “ethnostate.” Here are 30 countries measured the same way by one researcher. A country’s main people is its biggest group by family roots, language or religious community.

    In the 1990s, Israel’s main group landed near the middle: 14th of 30, next to the UK and Russia. Japan, South Korea, Italy and Poland had much bigger main groups.

    James D. Fearon, “Ethnic and Cultural Diversity by Country,” Journal of Economic Growth 8 (2003): 195–222, and his group data file · Figures from the 1990s (United States: 2000 census) · Israel: Fearon’s Jewish and Arab-citizen groups only; his separate West Bank and Gaza group is left out

    Jews are a people: tiny in number, more than 3,000 years old, and still here after every empire that ruled them is gone.

    Lesson 2 · 4 min

    Ideas that made kings nervous

    Why would an idea about God make a king furious?

    Two ways to see the world, 3,000 years ago

    Ancient Egypt
    Many gods↓Pharaoh is one of them↓Everyone obeys Pharaoh

    Questioning the king means questioning a god.

    The Israelites
    One God↓The law, for everyone↓Kings and people alike

    Pharaoh is only a man. Even kings answer to the law.

    Six big ideas. Tap each one to see why rulers hated it.

    Put together, these ideas say one thing: you don’t have to bow. People in power have rarely liked hearing it.

    Lesson 3 · 4 min

    The ruler’s decree

    Imagine you live in a small community that loves its traditions. One morning, this is posted in the town square:

    Hear ye, hear ye!

    Proclamation

    By decree of the new Ruler of this town


    From this day forward, all people must give up their old customs and obey the Ruler’s laws without question.

    Private meetings and local decisions are banned. Anyone who speaks against the new system will be punished.


    Posted in the town square by order of the Ruler

    What do you do? Be honest.

    A small group that refuses to blend in makes powerful people uneasy. Those people need a story that explains why the group deserves to be punished. That story is the Big Lie.

    Lesson 4 · 7 min

    How the lie works

    You already know how this trick works. You’ve seen it in movies.

    The Lion King

    Scar kills the king, then convinces young Simba that the death was Simba’s fault. Simba runs away in shame.

    Mean Girls

    Regina keeps a “Burn Book” full of nasty rumors about classmates. She adds an insult about herself, scatters the pages around school, and blames her ex-friends for writing it. Everyone turns on each other.

    Antisemitism, hatred of Jews, is usually described as a feeling, like dislike or prejudice. The writer Dara Horn argues it works more like Scar’s trick: a lie told by people who want to gain power or keep it. And it is always the same lie. She calls it the Big Lie.

    The recipe behind every version of the lie

    Scar and Regina each told one lie to get ahead. The lie about Jews is different: it has been told again and again, in every century, and it always follows the same three steps.

    Step 1Find what people love most.
    Step 2Say the Jews are destroying it.
    Step 3Now attacking Jews feels heroic.

    What the lie is not

    Criticizing Israel is not antisemitism. Arguing about a war, a government’s decisions, or a policy you think is unfair is ordinary political debate, the same kind people have about every country.

    When it becomes the lie

    It crosses the line when it follows the same old pattern:

    • Jews as a group are blamed for destroying what people love.
    • Jews are said to secretly control governments, banks, the media, or the world.
    • Jews anywhere are treated as guilty for a government they don’t run.
    • The one Jewish state is singled out as uniquely evil, the enemy of everything good, with no right to exist.
    Know the word

    Zionism is the idea that Jews, like other peoples, have the right to govern themselves in their ancient homeland, the land of Israel. That’s it. You can be a Zionist and still criticize any Israeli government.

    The lie redefines the word, so that “Zionist” stands for racist, colonizer, Nazi or secret puppet master, and then attacks Jews under the new label. Turning “Zionist” into an insult like that was a Soviet propaganda project.

    Swapping the word “Jews” for “Israel” or “Zionists” doesn’t change the lie. If a claim fits the pattern, it is still the same old lie, now aimed at the Jewish state.

    And the charges are old ones. The “secret Jewish plot” behind so many of them was made famous by the Protocols of the Elders of Zion, a forgery created by Russia’s secret police under the tsar and first printed in 1903. It spread widely during Russia’s civil war of 1918–21, when pogroms (violent attacks on Jewish communities) killed tens of thousands of Jews, by many counts more than 100,000.

    Word watch

    In fall 2024 a school invited Dara Horn to speak about antisemitism, and a staff member warned her to be careful with “the Z word.” She asked if she should also skip “the J word.” Her point: turning a Jewish word into an insult, then asking Jews to drop it, is an old trick. Learn each word’s real meaning first, and the insult version can’t fool you. Flip each word, and tap ? for the evidence.

    Jew

    From Judah, a son of Jacob in the Bible, whose name comes from the Hebrew for “praise” or “thanks.” So “Jew” means something like “grateful to God.” Jews have been called by this name for more than 2,700 years.

    Zion

    Zion is a hill in Jerusalem, and an old name for the city itself. It fills the Bible and the prayer book, synagogues face toward it, and in 1890 it gave rise to a new word: “Zionism.”

    Zionist

    A Zionist supports the idea that Jews, like other peoples, have the right to govern themselves in their ancient homeland, the land of Israel. That’s it. Most Jews are Zionists in this sense, and Zionists can still criticize Israel’s government.

    First “Jew” was made an insult, and Jews were expected to hide it. Now some people, even friendly ones, ask Jews to drop “Zionist.” Hiding “Jew” never stopped the hate. Criticizing Israel isn’t the lie. The lie is using “Zionist” as a costume for “Jew” to bring back the old charges. Keep the word and its real meaning.

    The Lie Machine

    Pick what a society loves most, and see what the lie says about Jews there. Notice which part never changes.

    Your decoder ring

    Turn the dial. Each stop is one question to ask about any story that blames Jews.

    1. Who is telling it, and what do they gain?
    2. What does this audience love most?
    3. How are Jews blamed for destroying it?
    4. What new media is spreading it?

    You’ll use all four on six real cases in the next lesson, and on anything you read after this course.

    Here’s the biggest clue that you’re looking at a lie.

    Click the buttons to change what society believes. Watch the accusation flip.

    A real complaint

    Points one way.

    too honest Shop cheatsyou

    If a business cheats you, it’s accused of cheating, not of being too honest.

    The lie about Jews

    Points every way at once.

    Jews

    Too rich and too poor. Too religious and godless. Too clannish and too eager to fit in.

    When the same small group is blamed for opposite things, you are not looking at evidence. You are looking at the lie.

    Opposite accusations against the same people are the fingerprint of the lie.

    Two rules to carry with you

    1Hearing something often doesn’t make it true.Scientists call the feeling it creates the illusory truth effect.
    2Popular doesn’t mean accurate.Online, the loudest and angriest posts travel farthest, and the careful ones get buried.

    The newest trickOrganized groups flood websites, forums, and online encyclopedias with false claims so that search engines and AI tools pick them up and repeat them as if they were facts.

    The lie is old. The megaphone is new. Likes measure how many people saw something, not whether it’s true.

    Lesson 8 · 7 min

    How a tiny people outlasted every empire

    Being targeted is not the most interesting part of Jewish history. Surviving it is.

    A story that saved a peopleWhen Rome destroyed Jerusalem and its Temple in 70 CE, the story could have ended. A famous legend says a teacher named Yochanan ben Zakkai was carried out of the besieged city in a coffin. He asked the Roman general for just one thing: a small school. Jewish survival came from choices like that one, made again and again, often at great cost.

    Choice 1: Literacy

    • A famous story says Hillel, a struggling day laborer too poor to pay for school, lay on a skylight in the snow to hear the lessons. When he became a leader, he dropped the fees.
    • Tradition says Rabbi Akiva, a poor shepherd, only began learning to read at 40. He became one of the greatest teachers in Jewish history.
    • Children were expected to ask questions. The Passover meal is built around them.

    Choice 2: Community

    • Some prayers need ten adults, so people keep showing up for each other.
    • In the 1100s, Maimonides in Cairo answered letters from Jews in Yemen and in France.
    • Communities pooled money to free captives they had never met. In the 1500s, Doña Gracia Nasi ran an escape network that brought refugees from the Spanish Inquisition to safety.
    • In 1991, more than 14,000 Ethiopian Jews were airlifted to Israel in about 36 hours.

    Choice 3: Memory

    • At Passover, every generation tells the Exodus story as if they had walked out of Egypt themselves.
    • Hebrew never fully died, because Jews kept writing in it for thousands of years. In the late 1800s it was revived as an everyday language, and millions speak it today.
    • Memory turns history into a story you belong to, and a story you belong to is hard to take away.

    The opposite of hatred isn’t love or empathy. It’s curiosity.Dara Horn, SAPIR, 2026

    What are you still curious about?

    Why do Jewish days start at sunset?

    In Genesis, each day of creation is “evening and morning,” so the day begins at nightfall. Shabbat starts on Friday at sundown.

    Are all Jews religious?

    No. Millions of Jews are secular, meaning not religious, and many don’t believe in God at all. They are every bit as Jewish, even by the strictest religious rules. A Christian or Muslim who stops believing often stops calling themselves Christian or Muslim. A Jew who stops believing is still a Jew, because being Jewish means belonging to a people, not signing on to a set of beliefs. The Hebrew Bible doesn’t even have a word for “religion.” When modern Hebrew needed one, it borrowed dat, a Bible word that means something closer to “law.”

    Where do Jews come from?

    The Jewish people began in the Land of Israel, in the Middle East, more than 3,000 years ago. From there, communities spread to Iraq, Iran, Yemen, Ethiopia, Morocco, India, Spain, Poland, Argentina, the United States and beyond, and people of every background have chosen to join. Many people picture Jews as white Europeans, but nearly half the world’s Jews live in Israel, and about half of Israel’s Jews have family roots in the Middle East and North Africa. And DNA studies show that even Jews whose families lived in Europe for centuries are more closely related to Middle Eastern Jews than to their non-Jewish European neighbors.

    What is the Talmud?

    An enormous record of debates about Jewish law and life, collected over centuries. It keeps the losing arguments too, so later readers can think for themselves.

    In Jewish tradition, arguing isn’t disrespect. Done right, it’s holy work. The name Israel means “one who wrestles with God.” Abraham argued with God to spare Sodom, and Job said, “I desire to argue my case with God.” In one Talmud story, a voice from heaven takes one rabbi’s side. Another rabbi answers, “It is not in heaven”: it’s up to people to interpret the Torah. And God laughs: “My children have defeated me.” Arguing to find the truth, not just to win, is called “an argument for the sake of heaven.”

    Why does Israel matter so much to many Jews?

    It is the ancient homeland, the one place where Jews have lived continuously for 3,000 years, and today it is home to nearly half of the world’s Jews.

    Even the word “Jew” comes from there. It means a person of Judah, or Judea, the ancient kingdom around Jerusalem. The proof is in the ground and in the language: a stone from about 2,800 years ago that names the “House of David”; a Hebrew inscription carved into a Jerusalem water tunnel around 700 BCE; the Dead Sea Scrolls, mostly written in Hebrew; and Roman coins stamped “Judaea Capta” (“Judea captured”) after Rome destroyed Jerusalem in 70 CE.

    What does “Zionist” mean?

    Zionism is the idea that Jews, like other peoples, have the right to govern themselves in their ancient homeland, the land of Israel. A Zionist is someone who supports that idea. It says nothing about any particular government, leader or policy, and many Zionists argue fiercely with Israel’s leaders. When someone uses “Zionist” to mean a secret cabal or an evil force, they have changed the meaning of the word.

    What do Jews do on Shabbat?

    It depends on the family. Jews who follow the tradition rest from Friday sundown to Saturday night: no work, no driving, no screens, just shared meals, prayer, reading, and long talks. Many secular Jews spend Saturday like everyone else, and plenty keep just part of it, like a Friday night dinner with candles and bread. They are all Jewish.
