Sibling Science

What this episode covers

In this episode about the science of siblings, we take a close look at the popular idea that your birth order can affect your personality or who you grow up to be. Are first born children more likely to be natural leaders? Are they more neurotic, having experienced the luxury of undivided parental attention only to be “dethroned” by the birth of younger siblings? Are younger siblings more free-spirited and less conscientious? Is there any actual scientific substance to birth-order theory at all?? In our listener question we talk about cannabinoid receptors – do we still have them even if we never partake in cannabis use? We now have patreon!
