Quizplus · Accepted Answer

Research suggests that first born children tend to have slightly higher IQs than their siblings. This could possibly be due to the parents' higher expectations and attention given to the first child, as well as the first born's exposure to more intellectual conversations and interactions with adults in the household. However, the difference in IQ is usually not significant and other factors such as parenting style, education, and genetics also play a role.
