“Personality and birth order in large families.”


Textbooks make claims like:

“Dixon [et al] studied 361 siblings belonging to large families and found that younger siblings were significantly more extraverted in terms of sociability compared to older siblings.”

Should we believe them? I look at:

Dixon, Reyes, Leppert, & Pappas (2008). Personality and birth order in large families. Personality and Individual Differences, 44(1), 119–128.
