Chemistry — Up to $40/hr

Tier: STEM

Chemistry subcontractors review AI-generated answers across organic, inorganic, and physical chemistry. Models often produce reaction mechanisms that look plausible but violate basic conservation, or balance equations on paper while getting the underlying chemistry backwards. We test for the disposition that catches both.

About the specialty

Chemistry review work pays at the STEM tier. The most common model failure is producing a reaction mechanism that draws the right arrows in the wrong order — the structure looks correct, the electrons move plausibly, but the actual transformation isn't what the model claims it is. Your job is to spot the gap between what's drawn and what would actually happen.

Topics covered in the test

The Cognition Test for Chemistry draws from a 150-question bank covering general chemistry fundamentals, organic chemistry, inorganic chemistry, physical chemistry, and reaction-mechanism review.

Difficulty mix

10 easy / 20 medium / 10 hard in the domain section. Behavioural section unweighted by difficulty.

Sample question topics

Stoichiometry and balancing; mechanism arrow-pushing review; functional-group identification; thermodynamic feasibility checks; spotting model-generated mechanisms that violate conservation rules.

What we test for

Mechanism literacy over memorised name reactions. We test for the disposition that reads what's drawn and judges whether the chemistry actually works.
