Yes, for its rigorous analysis of sexual conflict through an evolutionary lens. Buss combines academic studies with relatable stories, offering actionable advice to reduce harmful behaviors. Critics praise its bold challenge to social science dogmas, though some note its focus on male culpability over systemic factors.

Buss’s theory posits that men and women face inherent conflicts in mating strategies: men often prioritize short-term sexual access, while women seek long-term resource provision. These mismatched goals drive deception, jealousy, and coercion, perpetuating costly interpersonal struggles.

Infidelity triggers intense conflict due to evolutionary risks: men fear paternal uncertainty, while women risk losing resources. Buss cites cross-cultural data on secret affairs, mate-guarding behaviors, and revenge tactics like revenge porn post-breakup.

How does David Buss address intimate partner violence (IPV)?

Buss links IPV to evolutionary triggers like mate value discrepancies (e.g., older men with younger partners) and suspicions of infidelity. He argues controlling behaviors, from surveillance to physical abuse, often stem from perceived threats to reproductive interests.

What practical advice does When Men Behave Badly offer?

• For women: Recognize “exploitability signals” (e.g., low self-esteem) that predatory men target.

• For couples: Align on long-term goals to reduce strategic mismatches.

Buss compares stalking rates in the U.S. vs. Japan, bride-kidnapping in Central Asia, and honor killings in patriarchal societies to demonstrate universal vs. culturally specific manifestations of sexual conflict.
