Research consensus

Three reads. Every input disclosed.

Member conviction and automated headline tone stay separate, so context never masquerades as a vote.

Wook Score input0disclosed signals

The page reports raw member actions. Wook Score resists repeat-action inflation by collapsing each person to one net stance, then applies finite-sample shrinkage. Headline tone is deterministic keyword classification—not a member vote, prediction, or recommendation—and is capped and discounted.
