For many years I've had the nature vs nurture debate with family and friends. I've always maintained that one's personality, etc, is something like 75% nature, and 25 nurture. Lots of disagreement on the topic.
I wanted to add a twist to it. As we all know sometimes siblings can be very different, or sometimes they can be pretty similar in disposition. My idea is that siblings that resemble each other might be more likely to be similar; siblings that don't resemble each other more likely to be dissimilar.
Here's my case history. I have two older half- brothers, they are 13 and 15 years older. I have one "regular" brother who is 1 year older. Lets call the half brothers #1 and #2, full brother #3, I'm #4. With these two older half-brothers, when brother #3 came along, he was quite a novelty. #1 and #2 were able to talk my parents into letting them raise him in a pen in the backyard. By the time I came along, they had tired of the experiment, and things followed a more traditional path. I don't really resemble brother #3, and our personalities are very different. I do rather resemble #2, and our personalities are similar.
To me, this would support the nature over nurture theory. Do you have siblings that could shed light on this? i.e.: do your have a sibling that looks AND acts different, or a sibling that looks AND acts similar?
