I'd have to agree with Jess. Being raised JW does give you a headstart on academic skills. I don't know that JW children are necessarily brighter, but it could seem that way when they have been taught to read so early, and converse easily with adults. But I think it all levels out by the end of elementary school, if education and schooling is not emphasized.
I suspect any cross--section of toddlers and young children will seem above average if they are taught in the same manner, with so much focus on reading, listening and speaking. I do have to say that being raised JW, no matter all the warped views and teachings, has taught me skills many of my classmates do not have. I can sit for several hours and listen to a less than inspiring speaker (professor or teacher) and pull out the interesting points easily. I learned to focus on lectures, and my listening skills are possibly better than average. (Although probably most of my friends would say I talk so much, when do I listen??? haha)
I also have found that, although I'm just now learning how to "research"--being taught to only use the WT index (bleh, what a joke), I do know how to "study." Most of my texts now look like my WT used to, with definitions and explanations written in the margins, and main points highlighted. So, while other students are easily just as intelligent, if not more so, I LOOK more competent in the academic arena. After all, in the DUMBs it was all about the appearances right? Funny how some of that stuff turned out to be useful after all.
