Dr. Gad Saad: Why Men Are Biologically Programmed to Cheat (It's Not What You Think)


Listen Later

What if everything you think you know about male infidelity is actually backward? Adrian Wells sits down with evolutionary psychologist Dr. Gad Saad to explore the uncomfortable science behind cheating patterns that show up across every culture on Earth.
🎯 What You'll Learn:
• Why male mammals (including humans) show higher variance in reproductive success and what this means for relationship behavior
• The real data behind infidelity rates across 37 different cultures and why the patterns are so consistent
• How countries with more gender equality actually show larger psychological differences between men and women, not smaller ones
👤 Perfect for: lifelong learners and anyone passionate about personal growth who wants to understand human behavior through a scientific lens rather than wishful thinking.

Dr. Saad has published over 90 peer-reviewed articles and his research has been cited thousands of times. This isn't opinion or theory. It's data from decades of cross-cultural studies that most people never hear about because the findings make everyone uncomfortable.
Look, nobody wants to hear that biology influences behavior. But ignoring the science doesn't make it go away. Understanding these patterns might actually help you make better choices in your relationships, not worse ones.
