"I can't think of any reason your biological birth order in itself would have an effect on your personality, although anything is possible!"
MBTI theory, from what I have read, suggests that one's best-fit type is something one is born with that does not change over time (i.e., changing one's best-fit type from one of the 16 to another). To that end it seems that dismissing biological birth-order in a study trying to gauge if there is correclation between birth order and cognitive-preference personality leaves questions unanswered regarding validity. Also if one could show statistical correlation between order in family of upbringing and MBTI type but no correlation between order of birth biologically, then there would be a challenge to the belief that MBTI type is more nature vs. nurture, biological vs. social.
Regarding my ESFJ wife, one could also claim that it makes sense that she has characteristics associated with the eldest child because those characteristics are descriptive of being an SJ type.
