Before every attempt, Brainback asks: how confident are you? One to five. One click. It feels trivial.
It isn't.
That single click enables three things. First, it feeds the calibration component of the Brain score — the meta-skill of knowing what you know. Second, it tunes the recall queue: high-confidence errors are more important to re-review than low-confidence errors, because they represent hidden gaps. Third, it changes the student's relationship to the attempt itself.
This third effect is the most interesting. Users report that being asked to commit to a confidence makes them think harder before submitting. It's a stop sign. It's a moment of metacognition installed in the workflow.
The click costs nothing. The data it generates powers a third of the Brain score. Interventions rarely have this leverage.
