A question I like to ask people is what are the odds Zion Oil has a commercial well at Megiddo (now at MJ#2). As the numbers of hits for wildcats (in general) are known, the answers I get back here is an indication of how much of a bias and the effect that bias has on them.
Most people here would say 50 to 80% chance. That kind of mis-information is unfortunate and leads to incredibly bad investment decisions, especially for the elderly.
