A research program and book by Ted Ladd & Priyanka Shrivastava

Skeptical
Intelligence

How to question AI — and everything else — without killing innovation.

Every leader has heard that AI will transform everything. What gets skipped is the harder question: when the volume of machine-generated answers explodes, how do you know which ones to trust? Ted Ladd and Priyanka Shrivastava's research names a fourth, teachable capability — skeptical intelligence — and this site holds both halves of it: the research and method, free to use today, and the book that brings them together.

The research

What is skeptical intelligence?

For decades, IQ measured raw intelligence and EQ measured emotional judgment. Now AI puts nearly unlimited information into everyone's hands — but none of the three tells you when to trust what a machine just told you. Ted Ladd and Priyanka Shrivastava's research names the missing piece: skeptical intelligence, a fourth capability alongside IQ, EQ, and AI itself, built from four teachable habits. Everything on this page through the resources below is free to use, independent of the book.

Curiosity with an edge

Ask what would change your mind

Look for what would disprove a claim, not just what confirms it.

Epistemic humility

Know the limits of what you know

Have an accurate read on what you — and your models — actually know versus assume.

Evidence discipline

Trace the claim back

Follow a claim to its underlying data, method, and assumptions before acting on it.

Counterfactual imagination

Generate the alternative

Build a plausible competing answer and test the original claim against it.

Skeptics Playbook

Question Well. Decide Better.

Eight steps for questioning an AI-generated answer before it shapes a decision you can't take back.

The eight steps

A practical routine for questioning an AI-generated answer before it shapes a real decision.

S

Solve

State what you're actually deciding, and why — push past the first version of the question to what's really underneath it.

K

Know

Write down your own preliminary answer before you look at the model's, so your judgment isn't contaminated by its language.

E

Evidence

Trace the sources behind the answer: how current they are, what's missing, and where the answer breaks down.

P

Phrasings

Rerun the question with the burden of proof reversed, and from a hostile skeptic's framing. See if the answer survives.

T

Tear down

Premortem it: how does this fail badly within a year? What question isn't being asked that should be?

I

Independent

Take it to a different model or a human expert. AI critiquing AI is not independence — shared training data means shared blind spots.

C

Conclusion

Map the evidence against the decision you set out to make. You decide. The model doesn't.

S

Speak Up

Voice your final conclusion and your remaining concerns to yourself and your team.

The Skeptical Quotient

Ted and Priyanka's research also produced a measurement scale for this skill, the Skeptical Quotient (SQ) — a first step toward letting individuals and teams assess their own ability to question and verify AI-generated claims. An online SQ self-assessment is in development; join the newsletter to hear when it's ready to try.

For educators and trainers

Skeptical intelligence extends critical thinking training for a world where students and professionals reason alongside AI, not just about it. The four-habits framework gives instructors a concrete, teachable structure rather than a general exhortation to "think critically."

We're happy to talk about adapting these materials for a classroom, onboarding program, or internal training.

The book

The research above is ongoing and free. The book is where it comes together.

Ted and Priyanka keep publishing, speaking, and refining the Skeptics Playbook as the research develops. Skeptical Intelligence, the book, is the definitive version of that thinking — one field guide instead of a scattered series of articles and talks.

Who is this book for?

Leaders

Setting the tone for how a whole organization questions AI-driven recommendations.

Product & innovation teams

Balancing healthy scrutiny against the speed that new products demand.

Educators

Teaching a generation of students to work alongside AI without over- or under-trusting it.

Professionals working with AI

Anyone whose daily judgment now runs through an AI-mediated workflow.

Skeptical intelligence started as a research question, not a book proposal: what actually separates people who use AI well from people who get burned by it? "Think critically" was never a real answer — the term has stretched to mean almost everything and, as a result, means almost nothing. The book is where we put the research into one place. It isn't a reason to move slower. It's a way to know exactly when you're safe to move fast.
