An article in the September 11, 2006, edition of "Time" magazine comments that the major 9/11 conspiracy theories "depend on circumstantial evidence, facts without analysis or documentation, quotes taken out of context and the scattered testimony of traumatized eyewitnesses", and enjoy continued popularity because "the idea that there is a malevolent controlling force orchestrating global events is, in a perverse way, comforting". It concludes that "conspiracy theories are part of the process by which Americans deal with traumatic public events" and constitute "an American form of national mourning."
