Episode notes
This week, Sare’s boss Brett McCallum has decided he’s not just running the company—he’s auditioning for the role of Dumb AF cohost. And what better way to kick things off than with a Dumb As Fact inspired by his own book: Are Kids Born Assholes, or Are They Taught to Be Assholes?
We tackle one of life’s biggest debates: Is nature or nurture more important? But in true Dumb AF fashion, things quickly spiral into absolute chaos.
From parenting philosophies to the profound role of condiments in life (seriously, we all have our favourites), we somehow find our way back to the science of what really shapes us—our DNA, our upbringing, or just a deep love for mayonnaise?
We break it down with 3 case studies:
🧬 The Jim Twins – Separated at birth, lived eerily identical lives, proving nature might just be in the driver’s seat.
🔪 Jeffrey Dahmer – Was he born a monster, or did his environment push him over the edge?
🚕 The London Taxi Driver Test (AKA "The Knowledge") – How memorizing thousands of street routes actually reshaped their brains, proving nurture might have the final say.
By the end, we think we have an answer… but also, we now know way too much about Brett’s deep passion for sauces. 🥫
