YOU ARE a rational person. When someone says the moon landings were faked, or that 9/11 was an inside job, you do not conclude that they must be in the know. Why, then, should you pay any attention to Jeffrey Epstein conspiracy theories, which have been swirling around since the last year of George W. Bush’s presidency, when Epstein pleaded guilty in Florida to procuring a child for prostitution. When everyone in America’s infotainment ecosystem is competing for attention, Epstein content generates more Epstein content until something else comes along to displace it. Ignoring this stuff seems wise. Yet there are reasons why a rational sceptic should spend a few minutes thinking conspiratorially.
