Pretty much. I wandered afield a bit, but the basics for "Q" are pretty much the same as all the fortune tellers, prophets, and similar throughout history:
1. Either implicitly or explicitly claim to hidden/special knowledge: spirits, physic powers, angels, or double-sooper sekret special plus one security clearance.
2. Obfuscate your "predictions" to keep them vague, so you can claim more possibilities as "hits"
3. Throw in some things that are just bleeding obvious, so you have a few guaranteed "hits"
4. Make sure you cater to what the mark wants to hear: "Grandma says she loves you", "The universe shows me you'll meet a tall, dark, stranger", "Clinton is set to be indicted"
5. Stress repeatedly the difficulty of interpreting/imparting/acting on your information to cover the inevitable misses: "The dead see possible futures, not the only one", "Dark forces sometimes alter the results of the predictions", "The Deep State is working hard against us"
There's a few other bits and pieces you can use to embellish, but that's pretty much your recipe for not just conspiracy theory, but building a following of people who believe you do have that special knowledge.
