According to experiments (first conducted in the Hawthorn plant of Western Electric in Illinois, people who are told that they are highly capable and are doing well will then do even better work than worse. The adage "Honey catches more flies than vinegar" suggests that changes resulting from praise or dispraise may not be lasting.
At my workplace, nobody employs the Hawthorne Effect ....so it should be no big secret that it sucks to work there.
