Can birth order affect personality? Birth order does not appear to influence personality in adults, according to several ambitious studies published in the past few years. This new wave of research relied on larger data sets and more robust statistical methods than earlier reports that claimed to find a relationship between birth order and personality.
Which birth order is the best? The best students tend to be the oldest of three children, with a brother less than two years younger than them and a sister at least five years younger.
Which birth order is the happiest? Moreover, we found that middle-borns showed the lowest level of happiness, compared to only children. Prior research demonstrated that parents rated that last-borns and only children aged 3–9 years were happier than first-borns and middle-borns in the US (20).
What does my birth order mean? Birth order refers to the order a child is born in their family; first-born and second-born are examples. Birth order is often believed to have a profound and lasting effect on psychological development.
