The loudest person at the table is not always the one deciding where everyone eats.

Volume is often a bid for authority rather than evidence of it. In most rooms, the person who actually determines the outcome is quieter, moves later, and is watched by the people who know how things work. Mistaking noise for power leads you to persuade the wrong person and ignore the one who matters. It is a common and expensive error.

In your next group situation, watch where people glance before agreeing. Notice who speaks little and is deferred to anyway. Direct your effort there rather than at whoever is filling the air.
