Evolution & Psychiatry:


"Many mental states that look like “malfunctions” can also be defensive programs (anxiety, low mood, disgust, vigilance) that trade comfort for protection. The logical move is to ask: “What problem might this state be trying to solve, and is it overshooting?” "

Mismatch is the default setting

"Modern environments amplify ancestral vulnerabilities: ultra-palatable food, chronic social evaluation, sleep disruption, sedentary life, information overload. We are ancient systems running in novel conditions. Ask yourself, “Where can I reduce mismatch in my life?” "

"Selection doesn’t optimise for happiness; it optimises for inclusive fitness under constraints. Traits that raise risks for a disorder can persist ... if they confer benefits in other contexts (creativity, ambition, vigilance, social sensitivity). A good formulation names the benefit side and the cost side."

Plastic systems complain loudly

Humans evolved unusually flexible minds which are capable of learning languages, social norms, and roles at speed. That flexibility comes at a cost. Instability under uncertainty. Rigid systems rarely snap but plastic systems bend constantly and complain loudly. Much modern distress can be attributed to the sound of plasticity under strain.

Status drives more than we admit

Status is more than just vanity, it is access to resources, mates, allies, and safety. Depression, anxiety, anger, perfectionism, and burnout can all be interpreted as incomplete responses to status threat, loss, or impossible ladders.

-----

Sexual psychology as a psychiatric variable

Mating markets, jealousy, rejection sensitivity, relationship instability, porn, and fertility-linked mood shifts shape distress more than we regularly capture. Treat sex and pair-bonding as part of the context, not just the background.

Clinicians should think like ecologists

A person is not a brain in a jar. They are embedded in micro-ecologies: sleep, light, movement, food, social rhythms, and daily work design. They are also shaped by macro-ecologies: housing, economic pressure, digital infrastructure, institutional incentives, and cultural scripts. The future of care incorporates ecosystem redesign, with therapy and medication used more precisely rather than as substitutes.

Meaning is not optional, it’s a regulator

Humans can endure pain when it has purpose and crumble when life feels pointless. Meaning is more than a philosophy; it shapes behavior, inflammation, sleep, and risk-taking.
