Reading Scientific Studies
Cut through sensational headlines and abstract summaries. Learn to audit study designs, decode statistical significance, and evaluate empirical evidence with a critical eye.
Like Duolingo, but for Reading Scientific Studies. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Auditing Design and Data and Detecting Spin and Building Consensus. It assumes you already know the basics.

Key ideas in Reading Scientific Studies
- The abstract and introduction present the authors' most optimistic framing.
- Pre-registration records show if the authors changed endpoints mid-trial.
- Consort flow diagrams expose selective dropouts and attrition bias early.
- Observational cohorts capture unmeasured lifestyle habits alongside the exposure.
- Healthy-user bias occurs when health-conscious people adopt many good habits at once.
- Statistical adjustments cannot fully remove residual confounding variables.
- Surrogate endpoints measure intermediate biomarkers instead of actual patient outcomes.
- Drugs can successfully alter a biomarker while causing off-target harms that raise mortality.
- Hard clinical endpoints like survival or fracture rates are necessary to confirm clinical benefit.
- Survivor bias distorts findings by evaluating only subjects who remained to the end.
- WEIRD samples skew psychological findings by testing Western educated groups as universal.
- Volunteer bias introduces participants who are more compliant than the real population.
- Active comparators pit new interventions directly against current standards of care.
- Placebo trials show whether a drug beats nothing, not if it improves existing treatment.
- Active-control trials expose whether higher costs or side effects justify marginal gains.
- Absolute risk reduction is calculated by subtracting the treatment event rate from the control event rate.
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Reading Scientific Studies the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
