I'd like some web or list of well-known laws of project management.
Examples: Pareto Principle, Law of 90%, Parkinson Law, etc.
Some days ago I read about one that say something like: "If you study how some group of people react to a certain thing that promises to perform better, they will surely perform better independently of the real 'cause'".
But I can't find the name. There's another of "The more expectation you give a person, the performance output it's gonna be better".
I'd like to have a more organized list of this "Laws". Any help will be appreciated.
