We often think of ADHD as a modern-day problem: a brain that struggles to keep up with the demands of today’s world. A lot of modern life expects us to sit still, focus for long stretches, and tune out distractions. In that context, traits like restlessness, impulsivity or difficulty concentrating can seem like flaws.
But what if ADHD isn’t just a disorder of modern life?
What if some of the traits that get labelled as symptoms, like impulsivity and restlessness, were actually useful in our evolutionary past?
That’s the idea behind the “Hunter vs. Farmer” theory of ADHD.
The core idea
The “Hunter vs. Farmer” theory suggests that some behaviours we now pathologise could have once been evolutionary strengths.
For our ancestors living in hunter-gatherer societies, survival would depend on your alertness, adaptability, and the willingness to explore. Traits like impulsivity or hyperactivity, which are common in ADHD, might have made someone better at hunting, foraging, or avoiding danger.
In contrast, farming societies would need to value focus, routine and delayed gratification - traits that might come less naturally to people with ADHD.
Not only does this mean ADHD might have had an evolutionary advantage, it also provides a theory as to why it might be so common today.
