Here is a claim worth arguing with: the biggest word in the English-speaking world is not between A and Z. It is one mark — ? — one curve and one point, understood on every continent, capable of reopening anything that was declared closed.
A four-year-old deploys it about a hundred times a day, treating the world as wonderfully strange. Then, somewhere between "because I said so" and the last exam memorized and forgotten, the gift is trained into silence — curious explorers converted into passive customers waiting for approved answers.
GSU's forthcoming title The Biggest Word in the World runs that training in reverse: second-order effects, counterfactuals, the evidence that's missing, the measure that became the target, feedback loops, hidden costs, base rates, and the discipline of saying — out loud — what would change your mind.
You don't have to wait for the book to start. The free Causal Reasoning certificate examines exactly these tools, right now: a real bar, a verifiable serial number, no account, no fee. The question mark is waiting to be picked back up. It never stopped being yours.
Questions Readers Ask
Is a question mark really a word?
The book argues yes — as a logogram, a pro-sentence, and a bound morpheme, a solitary '?' does the full work of a word, and often of a sentence. Agree or not, the argument will sharpen you.
What is causal reasoning?
The skill of tracing what actually causes what: consequences, counterfactuals, missing evidence, and the traps that fool confident people daily.
Is the certificate really free?
Yes — like every GSU certificate: a genuine examination, a publicly verifiable result, no account and no fee, ever.
