Reading well means checking the procedure, the characterisation and the controls against the claim, and noticing what has been left out.

Ask what would have to be true for it to hold: repeatable measurement, pure sample, evidence matching the claim exactly. Then read laterally: leave the page and see what other trusted sources say about the same claim. Check the characterisation against the claimed structure; it usually sits in the supporting information. Proton NMR integrals must count the right number of hydrogens, and a high-resolution mass must match the formula within a few ppm. Then separate what the data show from what the discussion asserts: a yield table shows how much product formed, not how it formed. **Example.** Test a claim by picturing the world in which a rival explanation is true. Suppose a paper credits light for a reaction, but warmth from the lamp might be doing the work. If warmth is the cause, a run heated to the same temperature in the dark still gives product. That run is the control that splits the two pictures. For a catalysis paper, state the claim in one line, name the two experiments that support it, and hunt the missing one. A missing control names the rival explanation the work left alive, and the procedure plus characterisation live in the supporting information, not the headline. **Recap.** Name the claim, list what must hold, split numbers from narrative, and name the control that is missing. ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Method Validation: Accuracy, Precision, Recovery and Robustness](https://lightmysky.com/learn/science/method-validation-accuracy-precision-recovery-and-robustness-mt_ihmF2fl4OC) ## Optional connections - [Significance Tests for Chemical Data](https://lightmysky.com/learn/science/significance-tests-for-chemical-data-mt_2-SDgPjOQk) ## Opens up - [Searching the Chemical Literature by Structure and by Reaction](https://lightmysky.com/learn/science/searching-the-chemical-literature-by-structure-and-by-reaction-mt_7vkNiUQ2uw)
