Why This Exists

You are going to encounter bad health information today. Probably before lunch.

It will show up in your feed, in your group chat, in a conversation with someone you care about. It will sound confident. It may cite something that looks like a study. And if you are not equipped to evaluate it, you will either believe it, argue badly against it, or walk away frustrated.

Root to Rx exists to hand you the tools. Not to tell you what to think. To give you the equipment to find out for yourself, and to help the people around you do the same.

This page is where those tools live. It grows every time a new one is released. Bookmark it. Come back when you need it. Bring someone with you.

Getting Rooted

If you just found Root to Rx, these three issues give you the foundation everything else is built on. Read them in order.

Issue 001, Read First

Why Distrust Is Rational

The history behind why people do not trust medicine, what actually changed, and why that history still matters for every conversation you will ever have about health.

Read Issue 001 →

Issue 003b, Read Second

The Skeptic's Toolkit

The ten questions that let you evaluate any health claim, from any source, without needing a science degree. This is the core instrument. Everything else in the Field Guide extends it.

Read Issue 003b →

Issue 004, Read Third

The Pipeline

How a molecule becomes a medicine. The full drug development pipeline explained plainly, so you understand what it actually takes before a treatment reaches a patient.

Your Field Equipment

The Tools

Each tool below addresses a different part of the evidence literacy challenge. Use them in sequence when you can. Use the one you need when you cannot.

Tool 01 • Evaluation

The Skeptic's Toolkit

For evaluating any health claim, from any source.

Ten questions that turn a headline or a social media post into something you can actually examine. Who funded it. Was it peer reviewed. How large was the study. Has anyone else replicated it. What does the scientific consensus say. The Toolkit does not tell you what to believe. It tells you what to look for before you decide.

This is the foundation. Every other tool in the Field Guide assumes you have read this one first.

Tool 02 • Source Evaluation

The Battlecard

For evaluating science communicators, not just claims.

Good science is getting drowned out. Bad science goes viral. The Battlecard helps you identify which communicators are actually worth following, and which ones are performing credibility without earning it. It is the Skeptic's Toolkit applied to people rather than papers.

Use it when someone cites an expert and you want to know whether that expert deserves the weight being placed on them.

Tool 03 • Information Hygiene

The SIGNAL Battlecard

6 steps for navigating health misinformation every day.

The Skeptic's Toolkit is for evaluating a specific claim. SIGNAL is for the daily habit. Before you share. Before you quote. Before you forward. Six steps that take thirty seconds and work every time.

SSource it. Trace the claim to its origin. Who made it, and what did they actually say?
IIdentify the study type. A press release is not a study. A mouse study is not a human study.
GGet the consensus. One paper is never the whole picture. What does the weight of evidence say?
NNote the uncertainty. Good science says we don't know yet. No uncertainty is a warning sign.
AAmplify what's real. Don't stop at wrong. Share content that gets it right.
LLink to the original. Attach the actual source. Not the headline. The study.

Tool 04 • For Young Readers

The Junior Skeptic's Toolkit

The same evidence habits, scaled for kids.

Five questions a child can ask out loud, write down, or color in. Built for kitchen tables, classrooms, and anyone raising a curious kid in a world full of health claims they didn't ask for. Same framework as the Skeptic's Toolkit, in a form they can actually use.

What do I notice?
What do I wonder?
What's my best guess?
How could I check?
What changed my mind?

The Sprout Asks Why coloring book series walks kids through these same five questions step by step, with space to draw and write their own answers.

Tool 05 • Conversation Protocol

The PAUSE Protocol

For staying in the room long enough to use the Toolkit.

The Skeptic's Toolkit tells you what to ask. PAUSE tells you how to be in the room when you ask it. Five steps that keep a conversation from becoming a fight. Use it when someone you care about is about to stop listening.

"Before we argue, let's research it together."

PPause. Curiosity, not combat. Don't respond yet.
AAsk the source. Where did you see that?
UUnderstand the bar. What would change your mind if this were wrong?
SSearch together. Look it up right now, before either of you digs in.
EEvaluate together. Not to win. Not to lose. To know.

If the bar for changing their mind is impossibly high, turn to the Skeptic's Toolkit.

Tool 06 • Conversation Protocol

The OPEN Card

For getting both people ready before PAUSE begins.

PAUSE keeps a conversation from becoming a fight. OPEN is what comes before PAUSE. It is a 4-step posture check for the person doing the helping, not the person being helped. Before you can ask good questions, you have to show up as someone safe to answer them.

"The evidence can't come in through a locked door."

OOwn your intention. Are you here to help, or here to win?
PPicture their story. They believe this for a reason you haven't heard yet.
EExplore before you explain. Enter curious.
NName something real you share.

Tool 07 • Engagement

The REACH Battlecard

For rewarding the communicators who get it right.

The algorithm rewards outrage, not nuance. So the honest creators, the ones reading the studies and checking the sources, fight uphill every day. REACH is how you put your thumb on the scale for them. Five moves, thirty seconds, no expertise required. Just intention.

"Every comment is a vote for the kind of internet we get."

RReact out loud. Leave a real comment, not just a like. One sentence beats an emoji.
EEcho a question. Ask the creator something. Questions pull replies and keep the post alive for hours.
AAnchor it. Hit save. Saves tell the algorithm this is worth keeping.
CCarry it forward. Send it to one person who needs it. A DM share is the single strongest signal there is.
HHold on. Watch to the end, rewatch the first few seconds, then follow. Watch time is the currency.

Download Free — The REACH Card

Tool 08 • Engagement

The STARVE Battlecard

For starving the pages that profit from your outrage.

REACH is where you point your attention. STARVE is where you pull it back. The pages that hurt do not grow on being right, they grow on engagement, and even your angry comment is fuel. STARVE is six moves for refusing to feed them, without mockery and without making a martyr.

"Your attention is a vote. Spend it on purpose."

SStop before you react. The first feeling is the bait. Do not act on it.
TThink about who benefits if you spread it. Outrage is someone's business model.
AAvoid amplification. No quote-share, no dunk. Even mockery feeds the reach.
RReport or mute. Use the tools that take it out of circulation quietly.
VVerify privately. Check it for yourself, off the public timeline.
EElevate the truth instead. Spend the attention on the post that gets it right.

Scripts for the Wild

What to Actually Say

The Toolkit gives you the questions to ask. This section gives you the words to use when you are in a live comment thread, a DM, or a conversation that is about to go sideways. Every script below is copy-paste ready. None of them are combative. All of them open a door.

Start Every Conversation Here

"Genuine question, not trying to be combative. I have been trying to understand this better myself."

When you want to ask who funded the research

"Do you know who funded the research behind this? Funding does not automatically make findings wrong, but it is one of the first things I check. It helps me understand what questions got asked and which ones did not."

When you want to ask if it was peer reviewed

"Has this been published in a peer-reviewed journal? I am not trying to dismiss it. Peer review just means other scientists had a chance to poke holes in the method before it went public. It is the difference between a claim and a finding."

When you want to ask about sample size

"How many people were in the study? A result in 20 people means something different than the same result in 20,000. Both can be interesting. They are just different kinds of evidence, and the headline usually does not tell you which one you are looking at."

When you want to ask about a control group

"Do you know if there was a control group? Without one it is hard to know if the outcome was caused by the treatment or would have happened anyway. That is not a gotcha. It is just how we tell the difference between a coincidence and a cause."

When you want to ask about replication

"Has anyone else found the same result independently? One study is a starting point, not a conclusion. What makes science reliable is that different teams can test the same question and keep getting consistent answers. Has that happened here?"

When you want to ask about scientific consensus

"Where does this finding sit relative to the broader research? A single study that goes against hundreds of others is not automatically wrong. But it should raise a question, not settle one. I am curious what the weight of evidence looks like."

When you want to ask about the expert's actual field

"Do you know what their background is? I am not asking to dismiss them. Expertise in one area does not automatically carry to another. A cardiologist commenting on immunology is still a doctor, but it is a different kind of authority than an immunologist would be."

When you want to ask if it is correlation or causation

"Does the study show that X causes Y, or just that they tend to appear together? A lot of health headlines are correlation findings written to sound causal. The distinction matters a lot for what you would actually do with the information."

When you want to ask about conflicts of interest

"Do they disclose any conflicts of interest? Most researchers do, and most conflicts do not invalidate the work. But knowing about them is part of evaluating evidence fairly. Same standard I would apply to any source, including ones I already agree with."

When you want to ask what would change their mind

"Honest question, not a trap. What would it take to change your mind on this? I ask myself the same thing when I hold something strongly. If the answer is nothing, that tells me I am defending a position rather than following the evidence. Worth checking."

When the Conversation Starts Opening Up

"I appreciate you actually engaging on this. Most people do not. If you are curious about how to evaluate health claims in general, I follow a newsletter called Root to Rx that breaks this down in a way that is actually readable. Link in bio."

Tools in Action

Every Root Room scene, indexed by issue and by the tool it demonstrates. Follow Debby's journey scene by scene, or filter by tool to find the moments where a specific framework appears in practice.

This library grows with every issue. New scenes are added each Thursday.

009	The First Day Vera joins her first clinical trial, with Auntie Nani as her site coordinator. Debby has a sharp response ready and, for the first time, does not send it. Sam walks her through consent, the IRB, and the data monitoring committee that exist to protect Vera.	PAUSE	Read →
010	The Weight of the Record Debby goes looking for the shortcut on purpose. Starting with Cora's OPEN card to check her own intention first, she audits the Gleevec approval and finds independent reviewers at every turn, plus olaratumab, a drug the money could not save. She posts what she found, and the Lab elevates the truth instead of the outrage.	OPEN REACH	Read →
011	The Access Arc Begins The science arc is done and the price is set. Debby and the Lab turn from amplifying the truth to refusing to feed the outrage that profits from the price story.	REACH STARVE	Coming soon

The Lineage

The People We Learned From

The tools in this Field Guide did not come from nowhere. They stand on decades of work by scientists, psychologists, and communicators who figured out how to reach people before we did. These are the shoulders Root to Rx stands on.

Carl Sagan

Astrophysicist and Science Communicator

His Baloney Detection Kit in The Demon-Haunted World is the grandfather of the Skeptic's Toolkit. What made Sagan exceptional was not the kit itself. It was that he led with wonder before he led with rigor. He made people feel the awe of not knowing before handing them tools to find out.

Read: The Demon-Haunted World (1995)

Hans Rosling

Physician, Statistician, and Global Health Educator

The most effective disinformation fighter of the modern era. His Factfulness framework named the specific cognitive instincts that cause intelligent people to hold systematically wrong beliefs. He never called people stupid. He named the instinct, showed how it fools everyone including experts, and then handed a corrective.

Read: Factfulness (2018)

Fred Rogers

Educator and Television Host

Before he said anything, he made people feel safe. That is not soft. That is neuroscience. People cannot receive challenging information when they are in a threat state. Rogers built psychological safety as the first step, every time. It is the thing most science communicators skip entirely.

Read: The World According to Mister Rogers (2003)

Adam Grant

Organizational Psychologist and Author

His central insight: the best communicators do not argue like prosecutors trying to win. They argue like scientists. Curious, open to being wrong, genuinely interested in what the other person believes and why. He also identified that the fastest way to get someone to reconsider a belief is to make them feel understood first, not corrected.

Read: Think Again (2021)

George Lakoff

Cognitive Linguist

Facts do not persuade. Frames do. People evaluate new information through existing cognitive frames, and if the information does not fit the frame, the frame usually wins. The communicator's job is to offer a better frame, not win an argument inside the existing one. This insight underpins the Reframe Card, coming to this Field Guide in late 2026.

Read: Don't Think of an Elephant (2004)

Brene Brown

Research Professor and Author

People reject information when receiving it would require them to feel ashamed of what they previously believed. The communicators who break through do not make people feel stupid for being wrong. They make changing your mind feel like growth, not defeat. The PAUSE protocol is built on this principle.

Clinical Research Glossary

20 Terms They Use That You Should Know

You will encounter these terms in study headlines, doctor conversations, and clinical trial listings. Here is what they actually mean.

No terms match your search.

Clinical Trial

A research study that tests a medical intervention in human volunteers to evaluate whether it is safe and effective. All approved medicines go through this process before reaching patients.

Informed Consent

The process by which a participant voluntarily confirms their willingness to take part in a trial after being told everything relevant about what it involves, including risks. It is not a one-time signature. It is an ongoing process.

IRB (Institutional Review Board)

An independent committee that reviews, approves, and monitors research involving human subjects. Its primary job is to protect participants. No trial runs without IRB approval.

Phase I Trial

The first human testing of a new treatment, typically in a small group of 20 to 80 people. The goal is to evaluate safety and find the right dose, not to prove the treatment works.

Phase II Trial

A larger study, typically 100 to 300 people, that begins to assess whether the treatment shows signs of effectiveness while continuing to monitor safety.

Phase III Trial

The large-scale trial, often thousands of participants across multiple sites, that provides the primary evidence of whether a treatment is effective and safe enough to seek regulatory approval.

Randomized Controlled Trial (RCT)

The gold standard study design. Participants are randomly assigned to the treatment group or a control group. Random assignment removes bias that would otherwise skew results.

Control Group

The group in a study that does not receive the treatment being tested. They may receive a placebo, an existing standard treatment, or nothing. Without a control group, you cannot determine whether the treatment caused the outcome.

Placebo

An inactive substance or procedure that looks identical to the treatment being tested. Used in control groups to eliminate the psychological effect of receiving any treatment at all.

Double-Blind Study

A study in which neither the participants nor the researchers administering the treatment know who is in which group. This prevents expectation from influencing results on either side.

Peer Review

The process by which a study is evaluated by independent experts in the same field before it is published in a scientific journal. It is not a guarantee of correctness, but it is a meaningful quality check.

Endpoint

The specific outcome a trial is designed to measure. A primary endpoint might be survival at five years. Secondary endpoints might include quality of life or side effect rates. Knowing the endpoint helps you understand what a result actually means.

Adverse Event

Any undesirable medical experience that occurs during a clinical trial, whether or not it is related to the treatment. Adverse events are tracked, reported, and reviewed as part of safety monitoring.

Efficacy vs. Effectiveness

Efficacy is how well a treatment works under controlled trial conditions. Effectiveness is how well it works in the real world. A treatment can be highly efficacious in a trial and less effective in practice. Both matter.

Correlation vs. Causation

Two things can be associated without one causing the other. A study that shows a correlation means two variables move together. A study that demonstrates causation proves one variable directly produces the other. Headlines frequently confuse the two.

Meta-Analysis

A statistical method that combines results from multiple studies on the same question to produce a stronger overall conclusion. A meta-analysis of ten studies carries more weight than any single study it includes.

Confidence Interval

A range within which the true result is likely to fall, given the sample size and variability in the data. A wider confidence interval means more uncertainty. A narrower one means the estimate is more precise.

P-Value

A measure of the probability that a result occurred by chance. A p-value below 0.05 is the conventional threshold for statistical significance. It does not tell you whether the result is clinically meaningful or practically important.

CRO (Contract Research Organization)

A company that provides outsourced clinical research services to pharmaceutical and biotech companies. Most large trials are run by or with the support of a CRO. They are a major part of the infrastructure that runs between a drug candidate and an approved medicine.

Principal Investigator (PI)

The physician or scientist responsible for the conduct of a clinical trial at a specific site. The PI is accountable for the integrity of the data collected and the welfare of participants enrolled at their site.

Go Deeper

Eight books that go further than this Field Guide can. Not an algorithm-optimized list. A genuine curriculum, in the order we would hand it to you.

The Demon-Haunted World

Carl Sagan, 1995

The book that started this. Sagan's Baloney Detection Kit is still the best single framework for critical thinking ever written for a general audience. Read this first if you have not.

Factfulness

Hans Rosling, 2018

Ten instincts that make smart people systematically wrong about the world, and how to correct for each of them. The most useful book on the gap between what we believe and what the data says.

Think Again

Adam Grant, 2021

The science of changing minds, including your own. Grant's central argument is that the ability to unlearn and rethink is the most undervalued skill of this era. The PAUSE protocol is applied Grant.

Bad Science

Ben Goldacre, 2008

A British physician's systematic takedown of how bad science gets made, marketed, and believed. Includes a detailed chapter on how to read a drug trial that is more useful than any methodology course.

The Influential Mind

Tali Sharot, 2017

A neuroscientist's account of what actually changes minds, which is rarely the evidence itself. Sharot shows that emotion, incentives, and social dynamics are the real levers. Essential for understanding why facts alone do not work.

Don't Think of an Elephant

George Lakoff, 2004

The shortest and most practical book on framing ever written. Lakoff explains why the frame determines how information lands, and why presenting facts inside the wrong frame makes them useless or even counterproductive.

Daring Greatly

Brene Brown, 2012

The shame research. Understanding why people cannot hear new information when they feel they will have to feel ashamed of their old beliefs is foundational to everything PAUSE is built on.

How to Talk to a Science Denier

Lee McIntyre, 2021

The most operationally specific book on this list. McIntyre spent time at flat-earth conventions and climate denier meetings to test what actually works in face-to-face conversations. The answer is mostly PAUSE, before PAUSE had a name.
