I used to very politely say that if there is free will then it's in all sorts of boring places, like whether you're going to pick up this or that fork as you begin your meal. There really is none: It's all biology.

Regardless of your sex, if you have elevated testosterone levels in your blood, you're more likely to think a face with a neutral expression is instead looking threatening.
Interpretation
What this quote means
High testosterone levels can influence how we perceive neutral facial expressions, making them seem threatening.
This quote by Robert Sapolsky highlights the psychological and physiological effects of elevated testosterone levels on perception. It suggests that individuals with higher testosterone may misinterpret neutral facial cues as aggressive or threatening, indicating a significant interplay between our biology and social interactions.

Yes, genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology, etc., etc. But the regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.

I expected social rank to be the determining factor in health, and in some ways that's true. But far more important is what sort of society that rank occurs in. Being low ranking in a benevolent troop is a hell of a lot better for your blood pressure than being low ranking in an aggressive troop.

Extinguished theologians lie about the cradle of every science as the strangled snakes beside that of Hercules; and history records that whenever science and orthodoxy have been fairly opposed, the latter has been forced to retire from the lists, bleeding and crushed if not annihilated; scotched, if not slain.
