Everybody’s Science

Everybody’s Science is about how scientific thinking actually works — and who it belongs to. Not facts to trust or refuse, but a way of reasoning with evidence that anyone can run and anyone can check.

For teachers who want science taught as a process, not a syllabus. For readers who just want to think more clearly. For the reader who’s been told not to trust any of it and has good reasons to wonder — and who wants to know whether what they’re sure of is something they checked, or something they were handed. For policymakers, school boards, anyone who has to act on evidence they can’t verify themselves.

And for anyone who loves a skeptic, or is one.

I am a high school biology and chemistry teacher. Before that I earned a PhD in microbiology and immunology, worked on tuberculosis in a lab, held a faculty appointment, and spent years in science policy at the National Research Council, AAAS, and the National Science Foundation. The book is written from the classroom, which is the vantage point that made the rest of it make sense.

The structure is the argument

The book does not open by asserting that evidence deserves your trust. That argument fails on exactly the reader it most needs to reach, and there is good research on why: handing better facts to someone whose position is anchored in identity tends to harden it rather than move it. A book that just handed you better facts would be repeating the error it is trying to diagnose.

So it demonstrates first and argues second. Ten chapters of close, checkable observation come before the book turns to the hard part — a streambank in Virginia, a warming ocean, a vaccine race, the chemistry of an ordinary morning. Only then does it take up how misinformation gets built on purpose, why trust in institutions broke down, and what to do with a claim you are not sure of.

1. Part I — Wonder. Where scientific attention comes from, and what it produces.
2. Part II — How Breakthroughs Happen. How scientists choose questions, and why most progress is not a lone genius.
3. Part III — The Science That Explains Us. Chemistry, climate, and disease, in the ordinary world.
4. Part IV — When Trust Breaks Down. Manufactured doubt, the shroud of misinformation, and the crisis in the universities.
5. Part V — The Path Forward. Voting on science, reasoning well, and what happens when fluency is mistaken for thinking.

The named ideas

The book’s argument runs through a set of named ideas — eight of them carried by a breakout box, five also by a figure. They are the reason this site exists: the book states them, and the site puts them to work on material the book never covers.

• The Welcome Test. An honest challenger and a bad-faith one make the same three moves. The question that tells them apart is whether the claim survives testing — and whether the person making it welcomes that test. Read the companion piece →
• The Reaching Standard. What a good evidentiary process is actually reaching toward. Not a calculable greatest good, but the better of two real options, chosen now, oriented by an ideal you never finish arriving at. Read the companion piece →
• Hypothesis space. Choosing a question is a skill, not an accident, and it can be taught. Read the companion piece →
• Pasteur’s Quadrant. Why the fight between basic and applied research is a false one, and what fills the corner that answers both questions at once.
• Two models for funding science. Curiosity-driven and mission-driven research are usually argued about as rivals. The best work needs both, and the argument is older than either side admits. Read the companion piece →
• What share of the federal budget actually goes to science. Most people guess high, by a lot. The real number changes what the argument is about. Read the companion piece →
• The four conditions for changing a mind. What has to be true before anyone revises a belief — including you. Read the companion piece →
• Claim, Evidence, Reasoning. The classroom move that makes a student show the step between what they saw and what they concluded — used pragmatically, not as a worksheet. Read the companion piece →
• The instrument versus the reasoner. A fluent answer and a thought are not the same object, and the difference matters more every year. Read the companion piece →

What this site is for

A book is finished when it is finished. The world it describes is not. This site is where the ideas above get used on new material, where the classroom work behind the book lives, and where the sources are kept in the open.

• The full bibliography — every source behind the book, by chapter. Nothing in the book was invented; this is where you check that.
• Look Around You — reflection questions and companion reading for every chapter, written to be handed to a student directly.
• Evidence — the ideas above, applied.

A note on being wrong

A book arguing that science earns trust by being correctable would be a strange book to write as though its author had never been corrected. So the book says how sure it is as it goes, and says plainly where it got something wrong.

Here is one. An early draft of Chapter 4 claimed that scientists have a term for what happens when a research design throws off something better than the result you set out for — that they call it collateral knowledge. Then I went looking for the source, the way the book keeps insisting you should, and there wasn’t one: the phrase lives in financial law, not in laboratories. I had assembled a plausible-sounding term of art out of two words I liked and my own certainty — exactly the failure mode I spend whole chapters warning students about.

The real term is older and better. Serendipity — not in the lucky-break sense, but in the one Robert Merton spent fifty years defending: the trained capacity to notice that an unanticipated result is telling you something, and to go after it instead of filing it. The wreckage stayed in the book, because it is the most useful thing in that section.

Corrections to this site and to the book will be kept in public here, dated, as they are found.
