Every pick has two signals. They answer different questions and we never bundle them into one number.
Effect size
How big is the change on working memory, in the units that matter for this outcome.
Confidence
How sure are we the effect is real for working memory, given the studies we have.
For every pick, the “papers” number is how many studies we've cataloged that test this entity for working memory. “Favorable” means the study reported the direction you want.
The tier badge (S, A, B…) on the entity itself is its overall research confidence across all outcomes. It's the same letter wherever you see this entity on the site, not specific to working memory.
