The Science of Charlatanism

or How to Create a Cult in Five Easy Steps:

Step 1: Keep It Vague; Keep It Simple. To create a cult you must first attract attention. This you should do not through actions, which are too clear and readable, but through words, which are hazy and deceptive. Your initial speeches, conversations, and interviews must include two elements: on one hand the promise of something great and transformative, and on the other a total vagueness.

Step 2: Emphasize the Visual and the Sensual over the Intellectual. Once people have begun to gather around you, two dangers will present themselves: boredom and skepticism. Boredom will make people go elsewhere; skepticism will allow them the distance to think rationally about whatever it is you are offering, blowing away die mist you have artfully created and revealing your ideas for what they are. You need to amuse the bored, then, and ward off die cynics. encountered science and education at some time, though briefly and unsuccessfully....

Step 3: Borrow the Forms of Organized Religion to Structure the Group. Your cult-like following is growing; it is time to organize it. Find a way both elevating and comforting.

Step 4: Disguise Your Source of Income. Your group has grown, and you have structured it in a churchlike form.

Step 5: Set Up an Us-Versus-Them Dynamic. The group is now large and driving, a magnet attracting more and more particles. If you are not careful, though, inertia will set in, and time and boredom will demagnetize die group. To keep your followers united, you must now do what all religions and belief systems have done: create an us-versus-diem dynamic. First, make sure your followers believe they are part of an exclusive club, unified by a bond of common goals. Then, to strengthen this bond, manufacture the notion of a devious enemy out to ruin you.

The Left follows step 5 to a tee. Actually, they follow the other laws pretty much too.
