Companies will pay you to virtually sit on mock juries to give attorneys and other jury consultants feedback on cases they are currently handling. Think of these as focus groups. The cases are real, but your verdict will do little more than give those involved a prediction of how things might go when it's time to go to court. You can earn fees ranging from $5 to $60. Be sure to read all the disclaimers and details. If this sounds interesting go to eJury.com or OnlineVerdict.com to find a case.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies.
