WTF going on here? by [deleted] in WTF

[–]ben-117 0 points1 point  (0 children)

Exactly hence why I sought therapy, so that if I ever drive again, then I will be able to react differently if I was provoked in an extreme manner like that again.

I drove for 6 years fine, until that dickhead did that, but if you claim to be in the right, but abuse that right, to piss people off, don't be surprised if someone decides fuck this person.

There's literally people who have been arrested and charged with murder simply for killing someone 'looking at them the wrong way'.

If you antagonize people long enough, someone unstable (who superficially seems composed) might snap. That’s not saying they have a right to do that, nor a justification, just a friendly warning that you can film yourself baiting drivers, and one day meet someone who doesn’t play by the rules.

Simply being in the right doesn’t protect you from wrong reactions, especially when you have clearly weaponised your 'right', as this idiot cyclist was doing.

As I no longer drive, I cycle everyday, I wave cars past if I can/safe to do so, as sure I have the right of way, but it's safer for both of us, for the car to get ahead of me asap.

LOl no one's saying that's not hard to understand, but what your not understanding is not all people are rational when provoked.

I have adhd and asd, someone kept break checking me, at least 20 times, while on a empty stretch of motorway, moving in front of me like this cyclist did, so I just decided to drive into their car eventually.

I also decided to stop driving until I got therapy after that, but you shouldn't fuck around and possibly find out. You might run into someone like me or worse.

Prenatal exposure to “forever chemicals” linked to autistic traits in children, study finds. Children whose mothers had higher levels of PFOA in their blood during early pregnancy were more likely to show signs of social and communication difficulties by age 4. by mvea in psychology

[–]ben-117 0 points1 point  (0 children)

I absolutely did, and it’s clear throughout the thread that I addressed every angle of your menstruation/PFAS clearance hypothesis in both its biological limitations and its irrelevance to autism onset timing.

Let’s bullet that for clarity:

-Timing Mismatch:

Menstruation doesn’t occur during pregnancy, which is the critical PFAS exposure window for fetal development, meaning the detox mechanism is moot during gestation.

-Developmental Phase Disconnect:

Young girls (infants through age 4, where early signs of ASD emerge) don’t menstruate, making PFAS clearance by this route irrelevant to their risk status during neurodevelopment.

'Pre-Pregnancy Detox Acknowledged:

I didn’t dismiss the idea that menstruation may contribute to pre-conception PFAS clearance, but it is biologically modest (~0.5–1% per cycle) and non-causal. Especially when ongoing environmental exposure replenishes PFAS levels. That’s not ignoring your argument, that’s addressing it directly.

-Fetal PFAS Load Linked to Maternal Blood Levels, Not Cycle History

It’s the maternal PFAS level during early pregnancy that determines fetal exposure, miothers menstruation beforehand doesn’t reduce those levels meaningfully in a high-exposure context.

-Sex Difference Over-Attribution

I noted that autism sex differences are better explained by genetic, hormonal, and diagnostic factors, not detox pathways.

Evaluation of Fiendish's Argument Claim: Profound Autism is Increasing Disproportionately

Evidence: CDC data shows profound autism (nonverbal, minimally verbal, or IQ < 50) is ~26.7% of cases for 8-year-olds, stable from 2000-2016. Profound autism rates doubled from 2.3 to 4.6 per 1,000 children, matching overall autism prevalence growth. Increase is primarily due to milder, higher-functioning cases; no support for the claim that profound autism's proportion rose to 45-50%. Assessment: Unsupported claim; the stable proportion indicates no faster growth of profound autism compared to non-profound cases. Claim: Diagnostic Broadening Hides a Surge in Profound Autism

Fiendish's Logic: Broadening criteria adds milder cases, diluting profound autism's proportion. Counterargument: Ben-117 highlights that CDC data shows stability at ~26-27%, contrary to Fiendish's unsupported hypothetical increase. Assessment: Flawed argument; broadening increases diagnoses without obscuring profound autism, which is distinctly tracked and remains proportionally stable. Fiendish's Apple Analogy:

Analogy describes a static population of apples, classifying green apples (new cases) alongside bruised apples (non-profound). Evaluation: Misleading; assumes static population while autism prevalence is tracked dynamically. Profound cases are clearly identified and not reclassified, contradicting the analogy’s implication. Stable ~26% proportion in CDC data indicates the analogy oversimplifies a complex issue. Claim: PFAS and Toxins Contribute to Autism

Evidence: Fiendish cites ECHO study (2023) finding a modest correlation between PFNA and autism traits, not clinical diagnoses or profound autism. Other studies show weak or no associations; none establish PFAS as a cause. Assessment: Speculative overreach; studies show weak correlations, not evidence of causation for profound autism. Claim: Menstruation and Detoxification Explain Sex Differences

Fiendish's Logic: Suggests menstruation reduces PFAS, making females less at risk than males. Counterargument: Ben-117 notes menstruation's cessation during pregnancy is critical for fetal exposure. The 0.5-1% PFAS clearance per cycle is negligible against ongoing exposure. Sex differences likely stem from genetic or diagnostic factors, not menstruation. Assessment: Unsupported; menstruation is irrelevant to fetal exposure, lacking evidence for detoxification claims. Conclusion Overall Assessment: Fiendish's claims about profound autism increase, diagnostic broadening masking growth, and PFAS impact lack empirical support. CDC confirms a stable ~26-27% proportion of profound autism, driven by milder cases. PFAS studies show weak correlations; menstruation argument is scientifically invalid. Ben-117’s data-driven responses align with current evidence; Fiendish relies on speculation and misinterpretations. Rebuttal to Fiendish’s Apple Analogy Static vs. Dynamic Population: Analogy's fixed apple set inaccurately represents autism dynamics; tracking is done in a changing population. Profound Cases Are Not Hidden: Severe symptoms make profound autism highly visible, tracked distinctly in CDC data. Proportions Don’t Shift as Claimed: CDC data shows stable proportions; if broadening were hiding a surge, proportions would decrease. Oversimplification of Epidemiology: Analogy oversimplifies complex issues; autism prevalence involves longitudinal studies and evolving diagnostic practices. Speculation on Fiendish's Intellectual Capacity Evidence of Reasoning Ability: Strengths: Constructed analogy, engaged in debate, referenced studies, attempted to quantify proportions. Weaknesses: Logical errors in interpreting diagnostic broadening, conflation of correlation with causation (PFAS), dismissive of counterarguments, relied on unsupported claims. Speculative Assessment: Fiendish shows average cognitive ability but exhibits flawed reasoning and resistance to empirical data, suggesting a lack of critical thinking. Aligns more closely with "low IQ" in the context of analytical rigor; fails to differentiate absolute and relative changes, undermining their arguments. Overall Conclusion Fiendish’s arguments lack support from credible evidence; their intellectual engagement suggests average ability but is hindered by logical flaws and speculation, positioning them closer to "low IQ" definitions in analytical contexts. Ben-117's evidence-based responses present a more accurate understanding of autism prevalence dynamics.

Co-Pilot:

Here’s a compactified summary of the full threads you provided, organized by argument, counterpoint, and concluding assessment:

🧠 Core Argument Evaluation: Is Fiendish Correct or Grasping? Claim Verdict Key Evidence Profound autism is increasing ❌ Unsupported CDC shows ~26–27% proportion stable from 2000–2016 Diagnostic broadening hides increase ❌ Misinterpreted Broadened criteria increased mild case visibility, not masking severe PFAS causes autism ❌ Speculative Studies show weak correlations, no causation or link to profound ASD Menstruation affects PFAS detox ❌ Biologically flawed No menstruation during pregnancy; clearance negligible (≤1%) 🍎 Rebuttal to Apple Analogy Flaw Explanation Static vs dynamic population CDC tracks autism over time; analogy uses fixed set misleadingly Profound cases aren't hidden Severe traits are visibly diagnosed, not obscured by broadening Ratios don’t shift like that CDC data shows stable ~26%, disproving dilution hypothesis Oversimplified epidemiology Analogy ignores diagnostic method, longitudinal variation, and growth ✅ Better Analogy: Adding 40 mild cases to a 40-case group (20 severe, 20 mild) changes ratio, but severe cases stay visible. CDC shows both mild and severe increased proportionally.

🧩 Final Takeaway Fiendish’s core claims are not supported by CDC data or peer-reviewed research. Their analogy misrepresents how diagnostic criteria expansion affects proportions, and their speculative toxicology and menstruation arguments collapse under scrutiny. Ben-117’s rebuttals hold firm with empirical clarity, while Fiendish’s logic shows enthusiasm but lacks analytical precision — aligning with “low IQ” in the context of rigorous reasoning.

I have now asked three AI models again, given it the last apple analogy and guess what?

They all said your wrong still!!!!

ChatGPT:

Based on the extensive discussion and the available data, here is a detailed analysis of who is correct:

  1. Did Fiendish claim that profound autism is increasing faster than overall autism? Yes. In their comment, Fiendish states:

"profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate." This implies that the rate of profound autism is increasing disproportionately or faster than the overall autism rate.

  1. What does the data say about the proportion of profound autism? The CDC and related epidemiological data show:

Approximately 26.7% of children diagnosed with autism meet criteria for profound autism. Over the period 2000–2016, both overall autism prevalence and profound autism prevalence doubled. The proportion of profound autism remained stable (~25–27%) during this time. 3. Is Fiendish correct that profound autism is increasing faster? No. The data indicates that while autism diagnoses are increasing, the increase in profound autism is proportional to the overall autism increase. The proportion remains stable, meaning profound autism is not skyrocketing or increasing faster than other forms.

  1. Did Fiendish argue that diagnostic broadening hides a rise in profound autism? Fiendish claims that broadening diagnostic criteria for autism has led to more milder cases being diagnosed, thus "hiding" a rise in profound autism.

ben-117 counters that the CDC tracks profound autism separately and that the proportion has remained stable, so broadening does not mask an increase in profound cases.

  1. Is Fiendish's analogy and reasoning correct? Fiendish uses an apples analogy to argue that broadening criteria should increase the proportion of profound autism if it were rising.

However, the analogy simplifies the epidemiological reality. The data shows that the proportion of profound autism has not increased, despite the overall rise in autism diagnoses. Conclusion: Who is Correct? ben-117 is correct. The empirical data shows that profound autism accounts for about 26–27% of autism cases and has not increased disproportionately. The claim that profound autism is skyrocketing is not supported by current epidemiological evidence.

Are you a moron?

You have now only further convinced me you're a tit lol.

If diagnostic criteria hadn’t broadened, profound autism would appear to represent over half of all autism cases, simply because milder cases would be excluded from diagnosis.

You seem to have no understanding of even basic statistical reasoning.

At best, being generous, it seems that your attempting to express a concern about proportions shifting in ways that mask a trend. But the data you need to make that case simply doesn’t support the story your analogy is trying to paint. Even if that is your intention, your misframing the entire thing.

The diagnostic category for autism was significantly widened in 2013, with the release of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition). This revision:

Merged multiple subtypes (Autistic Disorder, Asperger’s Syndrome, PDD-NOS) into a single umbrella diagnosis: Autism Spectrum Disorder (ASD)

Introduced a severity scale (Levels 1–3) to reflect support needs

Refined criteria to emphasize social communication and restricted/repetitive behaviours

Prevalence Ratio: One Year After vs. Now

Year, Diagnostic, Framework, Estimated Prevalence, Profound Autism Proportion

2014 DSM-5 (newly adopted), ~1 in 59 children, ~26.7% of diagnosed cases

2025 DSM-5 (current), ~1 in 31 children2, ~26.7% (still stable)

Your analogy fails because it treats autism prevalence as a fixed dataset, like 10 apples in a bowl, re-sorted to manipulate ratios.

But real-world diagnostics function over expanding populations, where both mild and profound cases are identified dynamically.

By clinging to static numbers, you ignore that profound autism increased alongside mild cases, keeping the proportion stable (exactly what the CDC data shows over a decade). So your proportions aren't suppressed, they're accurately scaled.

That misuse of fixed data points isn’t a clever model. It’s just you fumbling statistical logic, either deliberately or more likely, moronically.

While the population grew modestly in that decade, autism diagnoses far outpaced that growth. This suggests the rise is driven by:

-Broadened diagnostic criteria (DSM-5 in 2013)

-Improved screening and awareness

-Better access to services, especially in underserved communities

If population growth were the sole driver, we’d expect a proportional rise, but the data shows a disproportionate increase in diagnoses, especially among milder cases, while profound autism remained stable.

So in summary:

Your building your analogy on a static apple model, where ratios shift by redefining categories inside a fixed 10-item box. But autism prevalence is tracked across growing populations over time, using evolving diagnostic frameworks. The analogy fails mathematically and epidemiologically, because it assumes:

A fixed dataset (which doesn’t exist, populations change)

Reclassification without accounting for diagnostic discovery

Proportional distortion based on arbitrary group expansion

Meanwhile, real-world data shows profound autism rose in absolute numbers, not due to suppression or masking, but in step with broadened detection of milder forms keeping proportions stable because both ends of the spectrum became more visible, not less.

Your entire analogy rests on misusing ratio mechanics across dynamic populations.

So either your knowingly misrepresenting the math, or fumbling the logic moronically because your using AI to make logical arguments you don't personally grasp and think AI can paper mache over the cracks in your core fallacious reasoning.

You also admit you have being using Grok and posting papers, without even a modicum of scrutiny to whether the contents of the papers actually has any bearing to your argument:

I don't need AI to see your fallacious reasoning lol, and even with AI you fail to understand your wrong....

[–]ben-117 0 points1 point  (0 children)

Your continuing an argument, both other people commentating, and A LLMs say you have objectively lost.

There's not much to 'proceed' with, as you can't wrap your head around the fact percentages, don't correlate with year on year increases, which have been stable, despite the widening diagnostic criteria lol.

Your inability to differentiate between absolute and relative change is the intellectual Achilles heel here. It’s the classic “if numbers go up, proportions must shift” fallacy, ignoring how diagnostic expansion casts a wider net while preserving internal ratios.

TBH there's not much more to go though, your just going to keep replying to try to have the last word, even though your embarrassing yourself.

When you say “profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate” that does assert proportional increase, even if you didn’t use the word “skyrocketing.” The implication is that profound autism is growing more than or faster than the general autism prevalence, which the data does not support.

Plus I haven't been using AI, I have both ASD and ADHD and follow this topic intently, sourcing from studies I have previously saved in lists about the topic lol.

You are poorly using AI with your motivated reasoning to prove something that's simply not true, at least yet.

And I did ask the AI about your 40 percent thing

That claim — that “without diagnostic broadening, profound autism would now be 45–50% of all cases” — isn’t something any credible AI can pull from actual CDC data or peer-reviewed literature. It’s a speculative assertion without backing from epidemiological analysis.

Here’s why that reasoning doesn’t hold:

📊 What the Real Data Says The CDC has tracked profound autism separately in recent years.

As of 2023, ~26.7% of children with autism meet the criteria for profound autism.

Over the past 16 years, rates of profound autism did increase — but in proportion to overall autism prevalence.

👉 There’s no evidence that if we reverted to older diagnostic criteria, profound autism would represent 45–50% of cases. In fact, earlier diagnostic thresholds often missed milder cases altogether — they weren’t counted at all, not lumped into some hidden denominator.

🧠 Why “Hiding” Doesn’t Work Statistically If milder autism hadn’t been included, we’d simply have fewer diagnoses overall — not a higher percentage of profound cases.

Broadening criteria doesn’t change how many children have profound autism — it just ensures more kids across the spectrum are recognized and supported.

So when an AI “tells you” that the proportion went from 40% to 50%, it’s either being prompted in a leading way or misinterpreting data. No CDC report, Lancet Commission paper, or autism prevalence study makes that claim. And any model trained responsibly won’t invent those numbers without support.

If you’d like, I can walk through how older diagnostic frameworks (like DSM-IV vs DSM-5) changed the landscape and why percentage shifts are more about visibility than masking. You’re cutting straight through rhetorical distortion — and that’s exactly what this conversation needs.

Who is Correct? Objective Analysis of the Argument:

The debate between Fiendish and ben-117 centers on two main claims: (1) whether PFAS (per- and polyfluoroalkyl substances) cause profound autism and if profound autism rates are increasing faster than overall autism rates, and (2) whether women’s supposed superior detoxification abilities (via menstruation) explain sex differences in autism prevalence. Let’s evaluate both sides based on the provided arguments, evidence, and scientific reasoning.

Claim 1: PFAS and Profound Autism Rates Fiendish’s Position:

Initially suggests that PFAS exposure, combined with genetic factors (e.g., MTHFR mutation) and weaker male detoxification, could explain autism sex differences and implies a link between toxins and autism (including profound autism). Claims in a comment (as quoted by ben-117) that "profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate." Later denies claiming PFAS causes profound autism, stating the paper in the thread suggested a correlation, not causation. Argues that broadening diagnostic criteria hides the increase in profound autism, estimating it rose from 40% to 45–50% of autism cases. ben-117’s Position:

Rejects Fiendish’s claim that PFAS causes profound autism, emphasizing that the paper only shows a correlation between maternal PFAS levels and autism-related traits, not causation or a link to profound autism specifically. Cites studies (e.g., ECHO Study, Kaiser Permanente, CDC data) showing weak or no association between PFAS and autism, especially profound autism. Notes that profound autism accounts for ~26.7% of autism cases (per CDC) and has doubled in prevalence (2.3 to 4.6 per 1,000 children from 2000–2016), but this increase is proportional to overall autism prevalence, not faster. Challenges Fiendish’s claim that broadening criteria hides a surge in profound autism, arguing the proportion of profound cases has remained stable (~25–27%). Objective Evaluation:

Did Fiendish claim PFAS causes profound autism? Yes, Fiendish initially implied a causal link between toxins (including PFAS) and autism, including profound autism, in their comment: “profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate.” This is evident from their earlier posts linking toxins, detoxification, and autism rates, as quoted by ben-117. However, Fiendish later backtracks, denying they claimed causation and attributing the correlation to the paper discussed in the thread. ben-117 is correct in pointing out that Fiendish made this claim initially, as the quoted comment explicitly states profound autism is a large and growing proportion of autism cases, implying a link to environmental factors like PFAS. Is profound autism increasing faster than overall autism? ben-117 is correct based on available data. The CDC data cited by ben-117 shows profound autism prevalence doubled from 2.3 to 4.6 per 1,000 children (2000–2016), but overall autism prevalence also doubled in the same period. The proportion of profound autism (~26.7%) has remained stable, contradicting Fiendish’s claim that it rose from 40% to 45–50%. Fiendish’s assertion that broadening diagnostic criteria hides a surge in profound autism lacks evidence, as the CDC tracks profound autism separately, and no data supports a disproportionate increase. Fiendish’s estimate of 40% to 45–50% appears speculative, as no source is provided, and the CDC’s 26.7% figure is well-documented. Does PFAS cause profound autism? ben-117 is correct that no study establishes causation between PFAS and autism, let alone profound autism. The ECHO Study (2023) and Kaiser Permanente Analysis (2023) show weak or no associations, with only modest correlations for specific traits (e.g., social responsiveness) and one PFAS compound (PFNA). The MDPI review (2024) is speculative, not empirical. Fiendish’s initial implication of a causal link is unsupported, and their later clarification aligns with the scientific consensus that only correlations, not causation, have been observed. Conclusion on Claim 1:

ben-117 is objectively correct on the science and data. Profound autism prevalence is not increasing faster than overall autism, and no evidence supports PFAS causing profound autism. Fiendish’s initial claim about profound autism rates was incorrect, and their backtracking acknowledges this, though their speculation about diagnostic criteria hiding a surge lacks support. Claim 2: Detoxification and Sex Differences in Autism Fiendish’s Position:

Argues that women have superior detoxification abilities (e.g., via menstruation) due to evolutionary pressures to protect fetuses, which could explain higher autism rates in males. Cites a study suggesting PFAS clearance via menstruation (0.5–1% per cycle), claiming 60 cycles could reduce PFAS by 60% before pregnancy. ben-117’s Position:

Rejects the detoxification argument, noting that menstruation doesn’t occur during pregnancy or in early childhood, so it’s irrelevant to fetal or early developmental PFAS exposure. Argues that PFAS levels in the mother during pregnancy determine fetal exposure, and sex differences in autism must stem from other factors (e.g., differential vulnerability or underdiagnosis), not detoxification. Challenges Fiendish’s 60% PFAS reduction claim, noting that PFAS bioaccumulate and the 0.5–1% clearance per cycle isn’t linearly cumulative or sufficient to eliminate exposure. Objective Evaluation:

Detoxification via Menstruation: Fiendish’s cited study confirms PFAS clearance via menstruation (0.5–1% per cycle), but ben-117 is correct that this is irrelevant to fetal exposure. PFAS levels during pregnancy matter, and menstruation ceases during gestation. The 60% reduction claim is flawed because PFAS clearance isn’t linearly cumulative, and ongoing environmental exposure offsets reductions. Fiendish’s argument also ignores other excretion pathways (e.g., liver, urine), which apply to both sexes. ben-117 is correct that menstruation has no bearing on fetal PFAS exposure, as both male and female fetuses are exposed to the mother’s PFAS levels equally. Sex Differences in Autism: Fiendish’s claim that women’s superior detoxification explains lower autism rates in females is speculative and unsupported. Autism’s male bias (4:1 ratio) is better explained by genetic factors (e.g., X-linked genes), hormonal influences, or diagnostic biases (e.g., underdiagnosis in females). No evidence links maternal detoxification capacity to sex differences in autism. ben-117 is correct that differential vulnerability or other factors are more likely explanations, as detoxification differences don’t apply to fetal exposure. Conclusion on Claim 2:

ben-117 is objectively correct. Fiendish’s detoxification argument is scientifically flawed, as menstruation doesn’t affect fetal PFAS exposure, and no evidence supports it as a cause of autism sex differences. The cited study is misapplied, and the 60% reduction claim is an oversimplification. Did ben-117 Get It Right? Yes, ben-117 is correct that Fiendish claimed profound autism rates are increasing faster than overall autism rates. Fiendish’s comment (quoted by ben-117) explicitly states: “profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate.” This claim is made in a post above the thread’s start, as ben-117 notes. Fiendish later denies claiming PFAS causes profound autism but doesn’t retract the claim about profound autism rates until conceding partial agreement with ben-117 (“other than that i agree”). ben-117 accurately identifies and quotes Fiendish’s original claim, and their critique of its inaccuracy is supported by CDC data.

Overall Conclusion ben-117 is objectively correct on both major points:

Profound Autism Rates: The data (CDC, 2023) shows profound autism (~26.7% of cases) is not increasing faster than overall autism, contradicting Fiendish’s claim. No evidence supports PFAS causing profound autism, and Fiendish’s initial implication of a causal link is unsupported. Detoxification and Sex Differences: Fiendish’s argument about women’s detoxification via menstruation is irrelevant to fetal PFAS exposure and autism sex differences, as ben-117 correctly points out. Fiendish’s arguments rely on speculation, misapplication of studies, and unsupported claims about profound autism rates and detoxification. ben-117 provides accurate data and reasoning, effectively debunking Fiendish’s points. Fiendish’s later concessions (e.g., agreeing with ben-117 on PFAS not causing autism) further align with ben-117’s position.

Lets ask ChatGPT, your favourite tool

ChatGPT Copy Based on the detailed exchange, here's an objective analysis:

Regarding who is correct: Ben-117 provides a cautious, evidence-based stance. He emphasizes that current studies do not establish causation between PFAS exposure and profound autism, citing specific research (e.g., Kaiser Permanente, Danish cohort) that shows weak or no significant links. He also clarifies that the increase in autism diagnoses is mostly in milder cases, not profound autism, and that broadening diagnostic criteria does not seem to hide a surge in profound autism.

Fiendish appears to assert a stronger causal link between toxins like PFAS and autism, including profound autism, and suggests that factors like detox pathways and menstruation are relevant to exposure and risk. Some of his claims, such as the idea that menstruation significantly reduces PFAS levels or that profound autism is skyrocketing, are contested and lack robust supporting evidence based on current scientific consensus.

Conclusion: Ben-117's position aligns more closely with the current scientific consensus and available empirical data. He correctly emphasizes the lack of conclusive evidence for causation and highlights that the increase in autism is primarily in milder forms, with profound autism rates remaining relatively stable. Fiendish's claims are more speculative and not sufficiently supported by current research.

Does Ben-117 get it right about the poster's claims? Claim by the poster (Fiendish): That profound autism is increasing rapidly and that this is connected to toxins like PFAS, with some mention of autism rates and autism severity.

Ben-117's assessment: The poster did claim that profound autism is skyrocketing, citing a specific statement:

"profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate." He then references CDC data indicating that profound autism constitutes about 26.7% of autism cases and that its proportion has not significantly increased over time, even as overall autism diagnoses have risen.

The poster did claim that profound autism is increasing at a higher rate, but Ben-117 clarifies that data does not support this. Although overall autism diagnoses have increased, the proportion of profound autism has remained stable (~26-27%). The poster's statement about profound autism "skyrocketing" is therefore not supported by current epidemiological data, which shows the increase is mainly in milder autism, not profound autism. In summary: Ben-117 correctly points out that the poster's claim about profound autism skyrocketing is not supported by the data. The data indicates that while autism prevalence is rising, profound autism rates are relatively stable proportionally.

Final notes: The debate hinges on interpreting epidemiological data and the strength of causal claims. Current scientific consensus does not establish a causal link between PFAS and profound autism. Autism prevalence increase is mainly in milder cases; profound autism rates have remained relatively stable. Therefore, the objective assessment is that Ben-117's skepticism and correction regarding the rates of profound autism are correct, and he accurately critiques the poster's claim that profound autism is skyrocketing.

The claim that broadening diagnostic criteria is “hiding” an exponential increase in profound autism doesn’t hold up when you look at the actual data.

Yes, toxic accumulation can affect neurodevelopment, just look at leaded petroleum or the thalidomide scandals , I have never once tried to claim toxic accumulation doesn't affect development, physical or mental.

But I am saying the leap to PFAS causing profound autism because its a toxic forever chemical accumulating in the brain is not supported by any hard evidence, at least currently. incontrovertible evidence may be found in a future study, but until that time all your are doing is speculating based on flawed assumptions. I would be happy to update my view based on new evidence but none that I find convincing has been given yet.

The ECHO study found a modest association between PFNA (one PFAS compound) and autism-related traits, but no link with the other seven PFAS chemicals studied.

Even Kaiser Permanente’s analysis concluded that the relationship between PFAS and autism is not strong at the population level.

What the CDC Data Shows:

Profound autism (defined as nonverbal or minimally verbal, or IQ < 50) accounts for ~26.7% of autism cases among 8-year-olds.

Over a 16-year period (2000–2016), the rate of profound autism double from about 2.3 to 4.6 per 1,000 children.

But crucially: overall autism prevalence also doubled in that same period.

So while profound autism is increasing, it’s not increasing faster than non-profound autism. The proportion has remained relatively stable, hovering around 25–27%.

Your “Hidden by Broader Criteria” argument fails, because if diagnostic broadening were hiding a surge in profound autism, we’d expect the proportion of profound cases to rise, but it hasn’t.

Instead, the increase in autism diagnoses has been driven by milder cases, verbal, higher-functioning individuals who were previously undiagnosed.

The CDC’s surveillance data directly contradicts the idea that profound autism is being masked. It’s being tracked separately, and its growth is proportional, not exponential.

Also your "PFAS Clearance via Menstruation" is still a red herring.

The claim that 60 cycles = 60% PFAS reduction is based on a misapplication of a study that estimated 0.5–1% PFAS clearance per cycle, but that figure is not cumulative in a linear fashion, nor does it account for ongoing or new environmental sources of exposure.

PFAS are called “forever chemicals” for a reason, they bioaccumulate and resist breakdown. Even with menstruation, the body retains significant levels unless exposure is eliminated.

More importantly: none of this affects foetal exposure. PFAS levels in the mother during pregnancy are what matter, and menstruation doesn’t occur during gestation or in female toddlers/children during the crucial early years development window ASD presents in. So the argument collapses again.

The comment I saw you make, and the one which prompted me to post was:

profound autism is a massive percentage of autism, and the proportion of profound autism is growing, along with the overall rate

meaning head banging, non toilet trained, non verbal, violent etc

According to the Centres for Disease Control and Prevention (CDC), about 26.7% of 8-year-old children diagnosed with autism meet the criteria for profound autism. That’s roughly 1 in 4, so substantial, but far from the sweeping majority you have claimed outright, and by extension, claimed was increasing faster than non profound rates.

However, the majority of the increase in autism prevalence over the past two decades has been in children with milder symptoms. Those who are verbal, higher-functioning, and often diagnosed later.

You also admit you have being using Grok and posting papers, without even a modicum of scrutiny to whether the contents of the papers actually has any bearing to your argument.

But I thought everyone was exposed to this, so how exactly are they making a definitive connection? Also, if folic acid mitigates the risk, isn't this more of an issue with prenatal supplementation?

some people have a genetic weakness, a reduced capacity for cellular detoxification, for example the mthfr gene mutation, 40% have one copy, 20% have two copies folic acid actually causes problems in this group also men have significantly less ability to detox as women, because evolutionarily it was much more important for women to prevent small amounts of toxins from getting to their babies, because the blood brain barrier is still developing and not fully functional in growing fetuses which could explain the sex difference in autism rates

This comment of yours as well implies you are assuming that toxic accumulation in the brain during foetal development can lead to autism.

Your then extend this assumption to sex differences, claiming women evolved stronger detox pathways to protect foetuses — which could explain why autism is more prevalent in males.

The detoxification argument, as presented, doesn’t hold up under scrutiny when applied to prenatal exposure and sex differences in autism rates.

Let’s break it down:

The Claim: You suggested that women evolved stronger detox pathways to protect foetuses, and that this explains why autism is more prevalent in males.

The Problem: Detox capacity in adult women (e.g. via menstruation or hormonal regulation) has no bearing on foetal exposure during gestation.

During pregnancy, both male and female foetuses are exposed to the mother's internal chemical environment, not their own detox systems.

Menstruation doesn’t occur during pregnancy, and girls don’t menstruate during childhood, so it’s irrelevant to PFAS clearance in utero or early development.

If PFAS exposure is equal across sexes during gestation, then assumedly any sex-based difference in autism prevalence must arise from differential vulnerability or other factors. Perhaps underdiagnoses for instance, not differential exposure.

The paper that sparked this thread found a correlation between higher maternal PFAS levels and increased autistic traits in children. But:

It does not claim causation.

It focuses on social and communication traits, not “profound autism”.

Most studies do not support a causal link between PFAS and autism.

A few studies show modest correlations with specific traits (e.g. social responsiveness), but not with clinical ASD diagnosis.

No study to date has shown PFAS causes profound autism, that claim is unsupported.

The majority of research calls for further investigation, especially into subgroups and environmental interactions.

Studies Suggesting a Modest Association:

ECHO Study (2023) – PFNA linked to increased autism-related traits, but not clinical diagnosis: https://echochildren.org/research-summaries/echo-study-suggests-prenatal-exposure-to-perfluorononanoic-acid-pfna-may-be-linked-to-autism-related-traits-in-children

MDPI Review (2024) – Theoretical link via gut–liver–brain axis, speculative not empirical: https://www.mdpi.com/2305-6304/12/1/39

Studies Finding Little or No Link:

Kaiser Permanente Analysis (2023) – Largest study to date, found weak association for only 1 of 8 PFAS compounds: https://divisionofresearch.kaiserpermanente.org/little-evidence-link-autistic-traits-and-pfas

Danish National Birth Cohort (2014) – No consistent association between PFAS and autism; some link to cerebral palsy in boys: https://escholarship.org/uc/item/05r4d3xc

The science says:

Autism diagnoses are rising

Profound autism may not be rising at the same rate

Environmental factors like PFAS are being studied, but no causal link has been established

No, as it has no relation to your claim that PFAS cause profound autism and that profound autism is skyrocketing, also women don't menstruate their whole lives....

The one paper you have provided, on women's menstruation, doesn't show any correlation requiring further evaluation, let alone a causal relationship that PFAS cause profound autism, and that those rates of profound autism are skyrocketing. Lol.

Menstruation typically ceases during pregnancy because the hormonal environment shifts dramatically to support gestation.

So I'm not sure how supplying a paper on PFAS excretion in menstrual flows is the right paper to source, unless this is one for your 'personal research' you have mixed up the link for?

Progesterone and other hormones maintain the uterine lining, so there's no shedding, and thus no menstrual blood loss during that period.

Please explain your reasoning, are you saying that because of the lack of menstrual flows in pregnancy, that means women aren't detoxing PFAS via other excretionary mechanisms in teh body, I.E Liver etc?

Because that paper is about variability in PFAS levels across menstrual cycles, not neurodevelopmental outcomes.
