You open ChatGPT. You type the question. A clean, structured answer comes back in three seconds. You read it, it makes sense, you move on. You feel like you learned something.
Forty-five days later, a professor walks in and hands you a test you weren't expecting. You don't remember most of it.
André Barcaui at the Federal University of Rio de Janeiro ran the experiment to find out if the feeling was accurate. 120 undergraduate business students, ages 18 to 24. All told to spend two weeks researching AI concepts, ethics, societal impacts, technical foundations, and prepare a 10-minute presentation.
Sixty used ChatGPT freely. Sixty used textbooks, library databases, articles, and standard web search. Then, 45 days later, with no warning, a retention test.
The ChatGPT group scored 57.5%. The traditional group scored 68.5%. Cohen's d was 0.68, a medium-to-large effect. In most grading systems, that's the difference between passing and failing.
This is called cognitive offloading. When your brain delegates thinking to an external tool, it reduces the mental effort required during encoding. Effort is what makes memories durable. Struggling to find, synthesize, and connect information is not an inefficiency in the learning process. It is the learning process. ChatGPT removes the struggle and takes the encoding with it.
Barcaui calls what the AI group experienced "borrowed competence." The answer was structured, the vocabulary was right, the reasoning felt sound. It just wasn't theirs. And 45 days later, it was gone.
The AI group's forgetting curve was steeper and didn't stabilize the way the traditional group's did. The memories weren't just smaller. They were more fragile from the start.
You didn't learn it. You borrowed it.

#Indonesia: Deeply concerned by horrific acid attack on Andrie Yunus, the Deputy External Affairs Coordinator of the Commission for Missing Persons and Victims of Violence (@KontraS). Those responsible for this cowardly act of violence must be held to account. HRDs must be protected in their vital work & able to raise without fear issues of public concern. - @volker_turk
Soal copyright:
Di dunia akademis, ada perusahaan mafia raksasa bernama Elsevier.
Grup pemilik Elsevier merampok £3.3 miliar per tahun.
Mafia Jurnal Elsevier menguasai distribusi jurnal akademis di planet.
Padahal, mereka tidak berkontribusi terhadap pengecekan kualitas jurnal.
Dosen dan peneliti yang mengecek keabsahan jurnal yang dipublikasi tidak menerima royalti apapun dari Elsevier.
Untuk mempublikasikan paper ke jurnal milik Elsevier, harus bayar.
Untuk mendownload paper dari jurnal milik Elsevier, juga harus bayar.
Elsevier sendiri hanya gabut saja. Mereka tidak melakukan apapun kecuali merampok dan memalak.
Akibat biaya random dan mencekik yang dipalak oleh Elsevier, hingga ratusan dollar per access paper, universitas-universitas di negara miskin menjerit.
Perkembangan riset di negara-negara miskin itu pun terhambat bahkan mati.
Bukan hanya negara-negara miskin, universitas di negara-negara kaya juga menjerit dan sempat mengadakan boikot.
Budaya publikasi preprint ke Arxiv salah satunya berasal dari sini. Jika paper dipublikasi gratis sebelum dipublish, kita tinggal download preprintnya saja.
Sekelompok peneliti di Kazakhstan pun membuat alternatif bernama Sci-Hub yang dengan berani membajak sebanyak-banyaknya paper dari Elsevier dan menguploadnya secara gratis
See how they're gatekeeping us from a decent life here?
This isn't only happening with gas, the reason why you barely could afford decent quality of food, why you couldn't afford decent education, even the fact that it's hard to find decent friend/romantic partner is all political.
Ibu jilbab pink yang berkata kasar bikin kamu ga nyaman? Good. Because there are ibu with soft-spoken words protesting in front of the presidential palace every Thursday since 2007, and you don’t give a damn. You don’t care about polite language. You just don’t give a shit.
