This might be the most disturbing AI paper of 2025

Scientists just proved that large language models can literally rot their own brains the same way humans get brain rot from scrolling junk content online.

They fed models months of viral Twitter data short, high-engagement posts and watched their cognition collapse:

Reasoning fell by 23%
Long-context memory dropped 30%
Personality tests showed spikes in narcissism & psychopathy

And get this even after retraining on clean, high-quality data, the damage didn’t fully heal.

The representational “rot” persisted.

It’s not just bad data → bad output.

It’s bad data → permanent cognitive drift.

The AI equivalent of doomscrolling is real. And it’s already happening.

This is hilarious! Now you have to protect your AI from stupid people not just your children.

Lastly, visiting social media online isn’t the ONLY way to “rot your brain”. Other ways include:

Not questioning what you are told and believing every word.
Not fact checking what you are told be fore you repeat it to others, and thus operating on hearsay.
Not learning the law so you have to rely on a corrupt lawyer or judge to tell you what the law requires. This makes you a useful idiot.

WELCOME!

SEDM is an entirely Member sponsored charitable religious ministry. We depend on your donations to maintain and improve our site, and to have resources to serve all of you.

THANK YOU to our valued Members and Member Subscribers. You are very appreciated. We work hard to earn and deserve your trust. Your participation, contribution, and constructive feedback is what allows us to fulfill our important mission and be a meaningful and relevant catalyst and force for good, empowerment, inspiration, and hope in an otherwise lost and dark world.

If you frequently use this site or find our work valuable or useful or rare, please consider donating to our worthy cause. Very few others we have found even come close to our high standards of scholarship, credibility, evidence, and quality. That is why we had to create this site to begin with because: 1. The subjects we cover cannot be found anywhere else on the Internet; and.. 2. We couldn’t find anyone who met our high standards of court admissible evidence upon which to base our beliefs. This site started as a repository for our own detailed research on the subjects it covers and blossomed into a ministry to lovingly do the same thing for all Truth seekers.

ADDITIONAL PAYMENT METHOD: PERSONAL CHECK

Our Bookstore lists credit card as the only available payment method. HOWEVER, we also permit personal check. To use Check as the payment method:

Enter the items in the cart that you want.

Go to the last step of checkout without actually paying to determine the Order number and total.

Complete a check with the Payee field blank for the amount listed in the almost completed order.

Scan in BOTH sides (FRONT and BACK) of the check in high resolution color, preferably as a PDF but you can us JPG format if you don't have a PDF scanning program. The resolution of the scan should be at least 300 Dots per Inch and preferably 600dpi COLOR, NOT black and white. Scan with a bed scanner and put the cover down or place a heavy item on top so the check is completely flat when scanned. DO NOT use a wand scanner or a smartphone picture, because they distort the image. "FOR" block should indicate "Donation" with the order number next to it if there is an associated order. Email to sedmorders(AT)runbox.com.

After we have successfully deposited your check, we will email you an order confirmation and a link to download your item. Normally it takes at least two days from the date we receive your check via email to receive the download link in your email inbox.

LIMITATIONS:

We can accept checks from only USA (not U.S.) banks. No foreign checks.

Sorry, but money orders or cashiers checks NOT accepted.

The payor on the check and the person ordering the item in the store need NOT be the same, so long as the payor gives you permission to pay from his/her account. If we don't receive an email with an image of the check within three days of the time you placed the order, we will automatically cancel and delete the uncompleted order. Please be prompt. This is the ONLY notice you will get about how to submit the check in payment so please take careful notes. THANKS!
