If you still believe COVID left the population “unchanged”, open a dating app. It sounds absurd, but stay with me here.

The cognitive bluntness is so widespread that the dating platforms themselves have had to acknowledge behavioural deterioration since 2020.

It’s not subtle🧵
Since 2020, apps report the same pattern: shorter messages, less reciprocity, fewer follow-ups, lower meet-up rates & a collapse in sustained conversational ability.

This isn’t just “people being tired”. It’s a measurable degradation of attention, initiative & social cognition.
The cause?

- repeated COVID infections impairing cognitive stamina/reward processing

- chronic low-grade fatigue

- dopamine systems altered by COVID/crises

- widespread emotional numbing

- increased avoidance as default coping mechanism

All the above = social “flatlining”
It mirrors broader post-COVID shift: people struggling to focus, plan, engage & sustain emotional presence

If dating apps feel like talking to NPCs now, it’s because they’re capturing, at scale, the behavioural signature of a population running on diminished cognitive bandwidth.
The irony? People who insist they’re “fine” are often the most dulled.

The denial comes packaged with reduced introspection.

If you’ve noticed the change, it’s not because you’re sensitive, it’s because you’re still capable of noticing.
This isn’t simply just “everyone being busy”. We had “busy” before.

We didn’t have this level of cognitive disengagement, emotional vacancy and social inertia.

Pre-2020, people were spontaneous. They responded. They showed interest. Now it feels like talking through fog.
Dating used to be about novelty, anticipation, spark, spontaneity. Now it’s marked by fatigue.

People aren’t choosing to be boring, they’re just exhausted in ways they can’t articulate. And the collective pretense that nothing has changed is making it worse.
If you feel like you’re interacting with a population that’s strangely blunt, avoidant, and cognitively thinner than before… you’re not imagining it.

You’re perceiving a post-2020 psychological landscape that most people are too depleted to notice.
MRI studies. Cognitive testing. Behavioural studies. All confirm COVID damages the frontal lobe: responsible for executive function

Depersonalisation: zoning out, emotional detachment, disconnection from one’s own actions… is also a frontal lobe linked failure of self-anchoring
When people’s attentional and emotional circuits are damaged, they slide into “observer mode”, not fully inhabiting their own decisions.

People on dating apps now behave like their executive functions are blunted:

- Sudden vanishings mid conversation
- No follow through
- Zero planning ability
- Disinhibited aggression
- Grandiosity
- Emotional flatness
- Treating matches like disposable objects
- Pathological indecision
- Effort dropping to absolute zero

This is the behavioural fingerprint of frontal lobe dysfunction.
Multiply this across hundreds of millions of people with repeat infections and you get a dating market where:

- Empathy collapses
- Long-term thinking collapses
- Emotional presence collapses
- Moral reasoning collapses
- Impulse control collapses
- Objectification skyrockets
- Attention span evaporates

This isn’t simply about “modern dating is hard”.

This is what a society starts to look like when its prefrontal cortex is under sustained biological assault.
Dating apps aren’t designed for post-COVID brains. They amplify every executive function deficit:

-Infinite scrolling for impaired impulse control
-Disposable options for impaired empathy
-Instant stimulation for impaired attention
-No consequences for impaired moral reasoning
People aren’t forming connections because they aren’t functionally capable of connecting in ways they did pre-2020

It’s a warning sign of collective neurocognitive decline, not a moral failure of individuals

Dating apps are the symptom. Frontal-lobe dysfunction is the disease.
Worth adding the frontal lobe regulates emotional intelligence, empathy, reward processing & affection. It’s highly sensitive to neuroinflammation & microvascular injury.

SARS-CoV-2 repeatedly hits these pathways.

So yes, you should expect social & romantic behaviour to degrade
“Oh so it was the virus and not screen time?”

Well, given that screen time doesn’t cause vascular inflammation, microglial activation, microclots, or measurable cortical thinning… yes, it was the virus.

Oh they know.

The reason any utter of the word “COVID” is met with awkward silence, abrupt subject changes, or mockery is no coincidence.

That’s what denial looks like when the stakes are too high for people to admit what they already sense.

You’re letting them off too easily.
Universal internet access & AI at everyone’s fingertips in year 6/7 of COVID. Yet we’re still pretending the public is merely “uninformed”?

This isn’t a knowledge gap, it’s deliberate avoidance, a psychological defence to shield people from the consequences of their own choices.
And here’s the part people pretend not to understand: we don’t rely on governments or legacy media for any other major issue

Nobody waits for official guidance to form opinions on Gaza, Epstein, climate collapse, corruption/surveillance. People “do their own research” constantly

There’s a pervasive misunderstanding in conversations about COVID’s neurological impact.

Many people assume that saying “frontal lobe damage reduces empathy” means everyone who’s had COVID instantly becomes amoral & unethical.

That’s reductionism at its finest. 🧵
Frontal lobe impairment is not an on/off switch.

Someone with naturally high empathy can still appear extremely empathetic, even if their capacity has measurably declined.

It’s a shift, not a reset.
At the population level, repeated SARS-CoV-2 infections subtly alter impulse control, moral reasoning and susceptibility to manipulation.

This doesn’t mean every individual loses morality, but society-wide trends can shift in meaningful ways.

Let’s talk about one of the most dangerous and under-discussed consequences of SARS-CoV-2: neurological damage. More specifically, frontal lobe dysfunction.

This is being deliberately downplayed, in part due to a misguided weaponisation of “ableism” discourse. That’s a problem🧵
Here’s the truth.

SARS-CoV-2 is a neurotropic virus. It can invade the central nervous system, either directly or through inflammatory damage.

It’s been detected in brain tissue, and it can cause lasting neurological impairment.

This is not speculative.
The frontal lobe governs executive function, impulse control, empathy, moral reasoning & inhibition. Damage here can lead to:

- Aggression
- Impulsivity
- Gullibility
- Bigotry
- Loss of social inhibition
- Apathy
- Antisocial traits

This is basic neurobiology, not ableism.

Calling it “ableist” to discuss SARS-CoV-2 related frontal lobe dysfunction misunderstands both neurology & ethics

Frontal lobe injury can cause apathy/disinhibition/moral blindness & aggression since these are the functions the region governs

This is neurobiology, not stigma🧵
Autism/ADHD/PTSD etc are forms of innate neurodiversity. Stable, lifelong neurotypes

Frontal lobe injury from COVID is acquired neurodegeneration. A progressive erosion of neural circuits governing empathy, foresight, inhibition & moral reasoning

Conflating the two erases both.
Frontal lobe damage, whether from traumatic brain injury, dementia or viral neuroinflammation, is well known to alter personality & behaviour.

It’s not a moral judgement. It’s anatomy.

The prefrontal cortex is literally the “brake” that tempers impulse, aggression & egocentrism

Cognitive decline from repeated SARS-CoV-2 infections & the rise of AI tools like ChatGPT = a perfect storm.

Here’s why this could reshape society in ways most people aren’t ready for 🧵
Repeat infection = cumulative damage to the brain. Particularly the frontal lobe, which governs empathy, foresight, impulse control & reality testing.

That’s the part of the brain that lets you question, reflect & doubt. Without it, a person becomes gullible, rigid & manipulable
Now layer on the rise of AI chatbots

People increasingly use them to write, think, argue, even feel for them.
And these models are designed to appease, to mirror your biases, validate your delusions and give you the emotional texture of understanding without any of its substance

We have not yet seen the worst of the neurological effects of Covid.

End.
What’s coming:

- Frontal lobe degeneration
- Personality & empathy decline
- Early-onset dementia
- Parkinson’s
- Alzheimer’s
- Motor neurone disease
- Chronic fatigue & dysautonomia

All accelerated by reinfection.

Reinfections that are happening 1-2x annually.
SARS-CoV-2 causes:

🧠 Neuroinflammation

🧬 Microglial activation

🩸 Microclots and vascular injury

⚡️ Disrupted dopamine and serotonin pathways

All of which are established pathways to Parkinson’s, Alzheimer’s and Frontotemporal Dementia.
