In this video, the author talks about his theory behind birth order. In sum, he said that the first born children tend to be more reliable, conscientious, list makers, don't like surprises, etc. while the youngest in the family tend to be the jokesters. He then said that the first born tend to seek powerful positions, like President, doctor, engineer, lawyer, etc. I found this very hard to believe. I am the second born and youngest in my family and I would say my sister is more conscientious and a "list maker", but I am more ambitious and have been more of a leader in the community and school than her.
Our textbook says, "Many popular books...claim that firstborns tend toward achievement, middle-borns toward diplomacy and later-borns towards risk taking. Yet virtually all of these claims are exaggerated, because most researchers have failed to uncover strong or consistent associations between birth order and personality."
Please watch the above video and let me know if you generally agree with his statements or not.
I am actually sitting next to my younger sister right now and felt the urge to share the topic of your post with her, simply to see if I could get a rise out of her! She actually seemed to agree though. I am an extremely organized and conscientious person, were she is more "go with the flow". After we discussed this with each other, I watched the movie you provided above, and found it crazy that even he confirmed this theory to be true. I also completely agree to why he says this is true. My parents have definitely lightened up with her, compared to me. I find my self saying "uh, that's not fair, I didn't get to do that until I was way older" all the time.
