Would changes made to a contract, after contract signing, be likely to be correct ?

Question

The book "Collins Class Submarine Story: Steel, Spies and Spin" suggested to me that an enormous amount of effort went into the project before the contract was signed.

So don't we have the problem "On a difficult question, the majority is unlikely to be correct? " (attributed to Descartes)

Most, perhaps every one, of the changes made to the contract, after contract signing, may probably be incorrect.

Answer 1

yes, they are more likely to be improvements. however, maybe the people who have already signed the contract wouldn't have knowledge of or wouldn't approve with the changes
