In a major blow to middle and younger siblings everywhere, researchers from numerous studies have found that the eldest sibling is usually just plain better. Now that's obviously a subjective term, and a holistic assessment would probably find different strengths and weaknesses in older and younger siblings, but in terms of intellect and leadership qualities, the elders just seem tot be better, at least according to Huffingtonpost. Older siblings mostly follow the rules According to a 2003 paper published by Belgian psychologists Vassilis Saroglou and Laure Fiasse in the journal of Personality and Individual Differences, the oldest sibling is usually more conventional, competitive and responsible, meaning they rarely break any rules. The younger siblings, on the other hand, usually exhibit signs of rebellion and playfulness.

Older siblings are usually more responsible

Yet again, being a guide for their younger counterparts seems to have surprising effects on them as well. According to certain research, eldest siblings are usually the ones who are more responsible, more obedient, and more oriented towards family loyalty and traditional achievement.

Older siblings are usually more successful and agreeable

According to a study from 2015, older siblings are usually more conscientious, meaning they are more organised, more goal oriented and thereby inclined to do well in life. They also tend to be more agreeable, which has been proven to be a major key to success.
