Fear gets you the minimum. Trust gets you the extra mile nobody asked for.

Frightened people do exactly what is required and not one step more, because anything extra creates exposure. That is a rational response, and it produces a group that is technically compliant and quietly useless. The effort nobody can demand only appears where people believe they will not be punished for trying.

Look at whether people around you volunteer things or wait to be told. If they are waiting, examine what happened the last time someone took initiative and it went wrong. Repairing that one memory does more than any new incentive.
