A few points... 1. Speaking of Dutchsinse, according to him we are likely to have a magnitude 6.0 or greater quake in Idaho within the next 5 or 6 days. Get the detectors ready. 2. It's difficult to prove a scientific point without data and just about as difficult with data. What data do you collect? How do you collect it? How much data should be collected (this is the hot one)? 3. The amount of data and repeatability is important. For instance - the book by Al gore "An Inconvenient Truth" has lots of data, graphs, charts and so forth. Seems very scientific. But it was proven to be very unscientific as much of the data was cherry picked. Had they included ALL the data in context the book would have proven the opposite point they were trying to make.
