A company’s “miracle study” is locked in the lab system. To release it for review, you must first diagnose what’s wrong with it. Examine the study and solve four reasoning locks — each one a flaw a sharp scientist would catch.
FizzCo claims its new drink, BrainFizz, "makes students smarter." They want it in every school. Before that happens, the study has to pass peer review. Open each document, find the reasoning flaws, and solve all four locks to release your audit. A good scientist doesn’t ask "does this sound exciting?" — they ask "does the evidence actually support the claim?"
Tap each clue to read it. (You can reopen them anytime.)
Solve each lock using the clues above.
You caught the tiny sample, the missing control group, the correlation-causation leap, and the conflict of interest. That’s how real scientific skepticism protects people from slick claims.
