Trauma responses make complete sense as evolved reactions to threat, loss, and social rupture. They become problems when the context that triggered them is gone but the system hasn't updated.

What motivates me in regards to Evolutionary Psychiatry is a certain disappointment with current Psychiatry. Psychiatry is the only medical specialty where the diagnostic manual has no clear validated biomarkers, the treatments are uncertain, and with effect sizes that would embarrass other fields.

Spicy Take: the DSM is often merely a cluster of symptoms named with a thesaurus. Describing a cluster of behaviours in Greek doesn't explain it. Naming is not understanding. We've confused the two for fifty years and called it progress.

"Chemical imbalance" was never really a theory. It was a metaphor that escaped its enclosure. Serotonin doesn't cause depression the way a broken leg causes pain. We know this. We kept saying it anyway because the alternative — genuine causal explanation — is hard.

Pertinacity is often valuable virtue. But what of it's negatives? We often make "perseverance " mean "tolerate conditions that shouldn't be tolerated." That's not resilience. That's adaptation to a bad niche. Evolutionarily, this isn't called success, it's called a constraint.

The smoke alarm doesn't malfunction when it goes off during burnt toast. That's the feature. Anxiety that fires too easily in a safe environment is doing exactly what it evolved to do. The context makes the poison - the problem is fitting it to the context, not the alarm system itself.

Psychiatry has thousands of papers on the what of mental disorder. Remarkably few on the "why". Evolution is the only framework that makes "why does this exist at all" a tractable question!

Causal stories matter. Telling someone their anxiety is a calibrated defence system that's overheating - not a sign they're broken - changes what recovery looks like. In fact, one study I, along with others, am publishing indicates this has a measurable effects on outcomes.

The irony of calling ADHD a disorder in the modern environment, which we might describe as one specifically engineered to disfavour sustained attention.

We treat "normal" sadness as clinical depression, "normal" anxiety as disorder, "normal" variation as pathology. The question we never ask: normal for what? For ancestral environments, these responses often made perfect sense.

Modern psychiatry: here is a drug to make the bad feeling stop.
Evolutionary psychiatry: what is the bad feeling for.

Despite the prevalence of Anxiety Disorders, Anxiety is not your enemy. It's a system calibrated for an environment that no longer exists. The question isn't how to turn it off. It's what it's trying to tell you - and whether that is appropiate for the situation at hand.

Conscientiousness and agreeableness as "slow life history" strategy markers: underappreciated how much personality psychology and life history theory (r/K selection) are saying the same thing in different languages.

Autism most likely built the internet. One might suggest that ADHD explored the continents. We are quite literally using the products of "disordered" minds to debate whether those minds are defective.

Even in principled egalitarian societies, status hierarchies don't disappear completely. They became harder to see and therefore perhaps harder to satisfy, this may tend to increase rumination, not reduce it.

People perhaps underestimate how much meaning comes from being needed - from not being replaceable . Pre-industrial humans were needed constantly. Modern humans are optional to almost everyone.

Status hierarchies are inevitable in human groups.

The question is not whether they exist, but whether they are legible, stable, and tied to prosocial competence. When hierarchies feel arbitrary, it is likely that dysfunction increases across the entire group.

I think to any observer, it seems fairly clear that we didn't evolve for 9-to-5 desk jobs, hyper-palatable processed food, and 24/7 digital social comparison. A lot of what we currently label as "mental illness" is actually a highly predictable mismatch between our brains and the modern environment.

Consider human emotions as part of a rational, self optimising system. Motivation emerges naturally when effort reliably produces legible, meaningful change in one’s environment. Where this link is broken, motivation collapses. No amount of exhortation can fully substitute.

The modern workplace selects heavily for sustained attention to abstract tasks in static environments. This is evolutionarily unusual. Human cognition evolved for movement, social interaction, novelty, and immediate feedback.

Feeling guilty over doom scrolling? Stress responses are regulatory systems designed to allocate effort in response to perceived demands and uncertainty, chronic activation often reflects structural conditions not necessarily pure personal responsibility.

Neurodiversity becomes more visible in highly standardised systems. The narrower the behavioural expectations, the more natural variation appears pathological. All may benefit if we consider alternatives!

Attention is not a fixed resource that some people “have” and others lack. It is a regulatory system that allocates effort based on expected reward and uncertainty. When outcomes are unclear or delayed, attention naturally destabilises. External structure often works better than pressure.

Many workplaces select for a narrow cognitive profile: sustained sedentary focus on abstract tasks. Human populations have historically evolved with broader specialisation.

Ancestrally, competence was publicly legible. There was strong coupling between environmental proficiency and social reputation - people needed competent hunters to survive! Today, it is often the case that forms of competence are opaque, delayed, or politically mediated.

For most of human history, effort → visible result → calibration.

Now effort → abstraction → delayed, ambiguous feedback.

Many “motivation problems” are likely actually calibration problems within modern environments .

Reframing ADHD. Economists have a concept known as 'Time Preference' - in short, that people prefer immediate rewards to anticipated future rewards. But to some degree all humans have a preference for 'now' over some distant future. Could ADHD be seen as an far range example of a normal human trait?
