I've observed that a large class of meetings are about bringing verifiers to bear upon solutions.

Typically, one individual has done the NP-Hard work of finding several solutions to a problem and asks for several others to bring their verifiers to bear on the solutions and identify the best one, or offer suggestions on how to tweak the solutions to move closer to an optimal solution.

Meetings cannot, however, find truly novel solutions. That's left up to the individual.
