Argue until a third opinion appears
Two Jews, three opinions
The old line goes: two Jews, three opinions. People tell it to show how opinionated and argumentative Jews are, but the arithmetic raises a sharper question: where does the third opinion come from?
How havruta works
It comes from havruta, the practice of studying Jewish text with a partner. Two people sit down with two opinions, and if they truly spar, each sharpens the other's thinking until they arrive at an idea neither could have gotten to alone. That third opinion is available only to people willing to engage the binary and move beyond it.
Beyond polarization
The same move works in politics and in every other realm. Polarization has grown so extreme that disagreement feels existentially threatening, and engaging with the other side feels like engaging with the enemy. Pulling the country farther apart cannot move it forward, so the engagement has to happen anyway.
How does havruta study actually work?
Partners sit across from each other in a study hall called a beit midrash and read a passage of Talmud aloud. Each one's job is to challenge the other's reading, so the room is usually loud with argument. The Talmud itself is built from recorded debates among rabbis across many generations. Many yeshivas still schedule hours of paired study every day.
Why does the Talmud record losing arguments?
The Mishnah, a Jewish legal code compiled around 200 CE, preserves minority opinions next to the winning ones. Tractate Eduyot explains the reason: a later court might agree with the minority view and rely on it. The Talmud also records the long disagreements between the schools of Hillel and Shammai and says that both sides spoke words of the living God, even though the law follows Hillel.
Why does dissent improve group thinking?
In a 2001 study in the European Journal of Social Psychology, Charlan Nemeth and colleagues compared groups that heard a real dissenter with groups that heard an assigned devil's advocate. Genuine dissent led people to consider more perspectives and produce more original solutions, and the assigned devil's advocate did not have that effect. Nemeth summarized decades of this work in her 2018 book In Defense of Troublemakers.
