The term “don’t drink the cool-aide” refers to what has become an almost blind following of faith in government, news programs, corporations, etc. If someone is “drinking the cool-aide”, it means they are swallowing (no pun intended) the rhetoric without questioning the motives. Or, more bluntly, believing the lies they are being told.
"The reason we are paying $<insert outrageous price here> for gasoline is because there is a shortage of petroleum. Here, have some cool-aide."
"We are consolidating positions and restructuring our organization to enhance communications and be better prepared to compete in a global economy. Pick up your check and enjoy our complimentary cool-aide."
