BoolQ

Reasoning

BoolQ pairs naturally occurring yes/no questions from search queries with a passage that decides them. The format is simple, but the inference it needs is consistently heavier than it looks.

At a glance

What a problem looks like

A yes/no question and the passage it is asked against. The boolean answer is not part of the prompt.

How it is scored

The source ships the boolean answer with every question; this catalogue keeps it in restricted storage and never renders it.

Metric: accuracy over the 3,270 validation questions

Why it is hard

The questions were written by people who wanted to know the answer, not to make a test, so they rarely line up with a single sentence of the passage.
