## Definition

The deterioration of decision quality that occurs after a prolonged period of decision-making. As cognitive resources deplete, individuals default to status-quo choices, impulsive actions, or outright avoidance. Research by Roy Baumeister demonstrated that willpower and decision-making draw from the same finite mental reservoir, meaning the tenth decision of the day is measurably worse than the first. In decision intelligence, offloading analytical heavy-lifting to structured AI debate preserves executive cognitive capacity for the judgment calls that truly require human intuition.

## About SynthBoard

SynthBoard is a standing board of AI experts that argue with each other on purpose, remember every call you make, and learn from how those calls played out. Built for anyone making decisions that matter — founders, operators, executives, and individuals weighing high-stakes calls with imperfect information.

Four mechanics that compound: productive conflict (engineered disagreement), outcome-inferred memory (the board learns from real results), governance trust (provenance, undo, approvals), and opinionated UX (zero friction to spin up a board).
