Is Parenting Overrated? (Encore)
Show notes
What shapes us more: our DNA or the way we’re raised? The “nature” camp points to genetic research and studies of twins raised apart, arguing that traits from personality to abilities are strongly influenced by inherited biology, limiting how much parenting can shape who children become. The “nurture” camp argues upbringing, culture, and parental choices profoundly influence development and behavior. So which matters more? This ethical conundrum is at the crux of this week's debate, originally broadcast in November 2019
