content: Well, it happens more often when one group chooses the 3 peer reviewers instead of using the tradition anon methodology. Almost every study done on this topic tends to be shotty, regardless of their conclusions. Its not an easy topic to draw well-founded conclusions on. The sheer amount of time a proper experiment would take to perform puts this research out of reach for nearly every scientist on the planet. The fact that human experimentation can't be used makes a proper experiment a parallel at best. The variance in self-reported cell-phone usage makes polls and surveys into guidelines on their best day. I with scientists would focus on other environmental dangers like pesticides and metals in the food/water/air supply. It's not like people are going to stop using cell phones if there was proof of cancer causing factors anyway.
