Jim Berkland claims that he can predict earthquakes. Can he or other people predict earthquakes better than chance?
This is certainly something that could be tested, but it would be hard. You would have to define the conditions for it to be meaningful, including
- How many predictions will he make?
- How close does he have to be to the epicenter?
- How close does he have to be in magnitude?
- What time frame counts?
"the next big earthquake along the ring of fire could be as early as this weekend." is rather broad. ANY earthquake of ANY magnitude ANYWHERE along the ENTIRE ring of fire counts? And if one doesn't happen, well he did just say it COULD happen. They only way he looses is if there is a big earthquake BEFORE this weekend - and even then he'd probably still claim he was correct.
