"Conspiracists are by nature anti-heroic—they believe that faceless networks must be far more powerful than ordinary individuals. A marginal figure like Ross could never have built his cocaine empire alone; Oswald could not have killed a president; a few dozen men in Afghan caves could not have brought down the Twin Towers. The romance of the conspiracy hunt lies in the way it transfers vitality from the assassin to the buff, at home alone, searching for the plot’s true source. In this, it matches perfectly the romance of the Internet, which perhaps explains why conspiracy has found such a resolute home there. If Ross, Oswald, and Hani Hanjour are merely pawns, then the story needs a hero, and the puzzle-solver himself raises his hand."
In a 2013 New York article, Benjamin Wallace-Wells looks at "50 years of conspiracy theory."
