> people usually agree with the loudest voice, not with the best idea

The problem with leaders is often, that they think they are the smartest and any idea not from them is automatically bad.

This is a problem. Often ideas are linked with people and not evaluated independently of that. We had success in our team with doing information gathering and idea generation as anonymous as possible. People can read and comment on ideas anonymously before it's discussed in person or decisions are made. That way people think of having a hand in the development of more ideas. This helps lessen the influence of large egos. Also it helps people who are shy to participate more easily.

> accept it or leave. Don't hold grudges

Also true. Grudges and constant complaining are not good for team spirit. However if people are often overruled and their reservations turn out to be true in the end, then your decision process sucks.
