The basis of science is an idea, a theory, a hypothesis. You look at the problem or situation or group of variables and formulate a plan to solve them. That is exactly what we need more of in paranormal investigations: new thoughts, ideas, inventiveness and gambles. Observe what other people are finding and keep your mind open to trying new things to explore those results. Even embrace the whacky off-the-wall experiments, If they payoff with results and evidence, you have rolled the dice and won. But lets remember to ALWAYS record and catalog your steps and results. Don't be the poor chef who comes up with a splendid new dish and forgets what he put in it!! Replication, duplication, and verification are key!
