A recent post was about some research on the lack of brain activity when using AI tools (here; Kosmyna et al., 2025; McBain, 2025). What I also found some interesting user comments generated by the article (McBain, 2025). One, by a tutor/teacher, said that "that Googling an answer does provide knowledge [...as] long as the answer provided is the correct one" (commenter "bettycallmeal", McBain, 2025). While I would suggest that bettycallmeal may have meant 'information', rather than "knowledge", I understood the gap she was seeking to bridge for her students between search and the necessary injection of critical thinking to sift the grain from the dross.
One search solution I use is to avoid Google as much as I can, part of Alphabet's empire. I avoid Google - and Chrome - most of the time because of Alphabet's profit motive. Google is a business, collecting my cookies to track my online movements, feeding me ads designed to get me to buy, and selling my search data, and skewing my search results towards its clients, and to previous user search results in my area. It is now what they 'do'. I am not annoyed at a business being true to its nature, but I do not like constantly being marketed to/at.
Instead, I sought out a search engine which had privacy at its core, and went with DuckDuckGo. DuckDuckGo aims "to protect the privacy of its users", and returns "the same search results for a specific keyword, without filtering those search results and personalizing them based on the [user's] history [to] the user" (Tyrsina, 2025). While I get fewer search results, often - not always though - those results are more accurate. Additionally, I use the Brave browser which while built on the Chrome platform, still slashes tracking cookies and advertising on my PC. On my mobile I use DuckDuckGo and Adblock browser. Those tools might also help bettycallsmeal's students.
But the problem is probably larger than just where we search. Another commenter (commenter "hureharehure", McBain, 2025) replied to bettycallmeal that another complication was that "the internet [...] is eating itself" - a timely reminder of the oroboros! - due to "much of the internet [now being full of] AI slop". It appears that many media platforms allow unreliable AI generated material to proliferate (read more here). Commenter hureharehure had found users to be "quite incurious about whether the information they seek is at all reliable" and pointed bettycallmeal to the following resources to assist her students (McBain, 2025):
- Users seeing the "AI-generated summary on Google search are significantly less likely to click on external links than users who don't" (commenter "hureharehure", McBain, 2025), with only 1% of users clicking on AI summary links (Chapekis & Lieb, 2025). Since Google’s AI Overviews launched in May 2024, 69% of Google news searches have users not clicking on any links, up from 56% (Barenholtz, 2025; commenter "hureharehure", McBain, 2025). So why is that, then?
- Well, because it appears that Google's AI summaries are giving people just enough information so they don't need to know more (JaĆșwiĆska, 2025). Though I must confess, if I get a news article summary and it is on a platform I am subscribed to, I won't click through on a Google News link: I will go straight to the platform so it lowers the platform's Google bill
- Apparently nearly a billion people already use ChatGPT (The Economist, 2025); we are not talking all the other LLM platforms through, such as Deepseek, Claude, Gemini, Copilot, Perplexity, and SciSpace for language work; Reclaim and SkedPal for planning; Midjourney, Dall-E, Firefly and Deep for images; Veo, Runway, Sora and Synthesia for video; Asana for calendar work (Karkar, 2025)
- Read an exploration of the "dead internet theory" (Prada, 2025) and a summary of platform slop, advertising and AI hallucination (Goodfriend, 2025; Koebler, 2025)
- Get a review of the forthcoming book by Cory Doctorow on internet 'enshittification' (Skopic, 2025)
These are things we should be telling our students, so they realise that any search is not necessarily a 'good' search. It may be a skewed search: for example, Google/Gemini AI search and summaries are likely to be skewed based on location search history, our national laws, local businesses who have Google Ad Words, and the data that has been fed into Gemini (Gleason et al., 2023).
If our students are not using their critical thinking skills but accepting what search has delivered up to them, then "Houston, we have a problem" (Howard & Graze, 1995, 50:52): and the research appears to already be showing that problem. Our less critical thinkers seem to be already experiencing brain rot (Karunaratne & Adesina, 2023; Kosmyna et al., 2025; McBain, 2025).
To me, more AI use seems unlikely to improve critical thinking skills, but to reduce them. And that is a serious problem.
