I came up with these in a Feb. 8, 1998 posting to CAJ-L, an email discussion list for journalists. I think they stand up, so here's a slightly-tweaked version: Read them, study them, absorb their lessons and then go forth and be controversial (the principles also apply to blog postings):
1. Do no research: Too many facts clouds the mind and makes the issue more complex, and that may make it harder for you to get into the proper state of agitation. A controversial column is a simple column.
2. Write fast and don't think: Again, by writing from your gut, quickly and without intellectualizing, you will achieve the Zen-like state of clarity you need to make a strong, simple, irksome point.
3. Avoid fairness like the plague: If people want fairness and balance, let them read some boring news story. You're expressing an opinion, and a controversial opinion is never fair. For that reason, be careful in your choice of words. As an example, you can't use the word "hate" too much in a controversial column.
4. Pick your targets carefully: The best controversial columns are ones that create public reaction, and to do that, you need someone to play along. Therefore, attack a group that already feels aggrieved or misunderstood. To really twist the knife, base your attack on a stereotype about which the group feels particularly sensitive. They'll seek publicity by attacking your column which in turn creates publicity for you. Everyone wins!
I would note that neither Heather Mallick or Ann Coulter need lessons from me.
