"Conspiracies" in the pejorative

I am surprised by the resistance from so many people to believe in "conspiracies" as if by definition, these things do not exist. Wasn't the Manhattan Project a conspiracy? Wasn't the attack on Pearl Harbor a conspiracy? How about the bombing of Hiroshima? Most people today agree that all of these things are a real part of history. These events all had this in common: 1) A number of people were involved in planning. 2) Most people prior to the event never heard about it. 3) A lot of people died.


Then I hear people say, "if it was such a big deal, I would have heard about it." You are hearing about it! If it is not what you want to hear, does that make it not worth considering? And from whom would you have to hear it in order to find it believable? The news? The news is a run-for-profit company owned by friends of those we accuse of committing the crime. Do you think the guilty party would come out and confess to their deeds, ever?
