Idiocracy Looms As Study Finds TikTok Rots Youth Minds
While IQ scores have historically risen alongside technological advancements, recent years have seen a slowdown—if not a reversal—in intelligence. The rise of smartphones, tablets, and social media may be to blame, and more recently, the phenomenon of the 'TikTok brain' among teenagers suggests peak cognition has arrived.
A new report from the Financial Times cites a test used to measure the IQs of 15-year-olds, conducted by the Program for International Student Assessment (PISA). This test evaluates students' performance in reading, mathematics, and science literacy. The latest data suggests that IQs peaked in the early 2010s.
Peak cognition fears come nearly two decades after the debut of the satirical sci-fi comedy Idiocracy, which depicted a dystopian future where humanity becomes profoundly dumbed down by the 2500s.
FT's chief data reporter, John Burn-Murdoch , said the timing of this data marks an 'inflection point' and is 'noteworthy' because it coincides with 'our changing relationship with information,' which is now primarily online.

Declining math and literacy skills are likely the result of a shift away from text-based learning toward visual media. Additionally, there is a broader erosion in the capacity for mental focus, which could be attributed to 'TikTok brain rot'—with youth spending countless hours each week mindlessly swiping into oblivion. It's clear that digital technologies have impacted attention span, memory, and self-regulation negatively.
A surge in the share of 15-year-olds who reported difficulties in PISA tests coincides with big changes in how information is processed, shifting drastically away from reading to visual content over the two decades.
Peak cognition fears suggest achieving full Idiocracy may happen at a much more accelerated timeline. Meanwhile, artificial intelligence could surpass human IQs by the next decade…
'I think today's systems, they're very passive, but there's still a lot of things they can't do. But I think over the next five to 10 years, a lot of those capabilities will start coming to the fore and we'll start moving towards what we call artificial general intelligence,' Google DeepMind CEO Demis Hassabis said at a briefing on Monday.
TikTok and other digital technologies that offer instant gratification through swiping left, right, up, or down appear to have made society even dumber.

Dopamine Is Not Why Kids Love TikTok
Nowadays, it seems we can be addicted to anything – not just alcohol and drugs, but pornography, random Internet browsing, video games, and smartphones. Academic research papers have investigated a wide range of other behaviors including gambling, but also 'dance addiction,' 'fishing addiction,' 'milk tea addiction,' and 'cat addiction.' One cheeky paper used the standard medical criteria to show young people are 'addicted' to their real-life friends. While this trend involves many factors, perhaps the single most important claim that has transformed what might be devoted or enthusiastic behavior into a presumed medical case of addiction is the presence of the neurotransmitter dopamine. Health experts and the popular press tell us that fun activities can give us 'dopamine hits' and that overindulging can result in 'dopamine blowout.' Indulging too much in naughty activities (somehow, it's always naughty activities) may create a 'dopamine deficit.' To cite a few of many examples: A Washington Post podcast declared that 'dopamine surges' explain why 'you can't stop scrolling, even though you know you should.' The Guardian reported that Silicon Valley is 'keen to exploit the brain chemical' to keep us hooked on tech. Earlier this month, CNN told readers, 'an addiction expert says it might be time for a 'dopamine fast.'' There's a problem with this scientific-sounding explanation for an alleged explosion in addictive behaviors: It is not supported by science. Solid research connecting dopamine spikes to drugs and alcohol – that is, the capacity of one chemical to ignite another – has not been shown to occur in similar ways with other behaviors. Drug use is fundamentally and physiologically different from behaviors that do not rely on pharmaceutical effects. This has been confirmed in humans: Technology, such as video games or social media, simply doesn't influence dopamine receptors the way illicit substances do. Experts say what we are seeing instead is pseudoscience that appears to legitimize a moral panic about behaviors that trouble certain segments of society. By falling for this pseudoscience, parents and others are at risk of missing more fundamental mental health issues that could be at the root of the obsessive behavior, potentially harming the very children they seek to help. 'Addiction is an important clinical term with a troubled and weighty history,' said Dean Burnett, a neuroscientist and coauthor of a brief explainer of what dopamine does and doesn't do. 'People enduring genuine addiction struggle to be taken seriously or viewed sympathetically at the best of times, so to apply their very serious condition to much more benign actions like scrolling TikTok makes this worse.' Burnett likens current narratives about dopamine and technology to 'science garnish,' effectively adding a dash of scientific language to nonsense beliefs. 'It's the informational equivalent of sprinkling parsley on a lasagna that's 90 percent horse offal,' he said. 'It may look nicer, but it isn't.' The pseudoscience, however, does play a useful role for parents and others who seek to restrict the behaviors they find disturbing. After all, 'Don't do X because it will dangerously rewire the reward circuits of your brain and cause addiction' is more compelling than 'Don't do X because I don't like it and think you are wasting your time.' Growing Mistrust of Experts At a time when science has been riven by a series of scandals involving unreliable and falsified research at universities, including Stanford and Harvard, the public is having a harder time distinguishing scientific truth from pseudoscience. As growing numbers of Americans question the veracity of many well-established findings, such as the safety of vaccines, the popularity of the dopamine myth amounts to another misreading of science to serve other purposes in a culture desperate for simplistic moral answers. Such answers can be found in bookshelves full of titles like 'Dopamine Detox' and 'Dopamine Reset.' These experts warn us that activities we think make us happy are actually making us unhappy in the long term because we're doing dopamine wrong. Advice sites are quite explicit about this: 'You can get dopamine either from rich sources like meditating, exercising, or doing something that is meaningful to you and that serves you in the long run. Or you can get dopamine from self-sabotaging activities like eating junk food, scrolling social media mindlessly, or anything that provides pleasure instantly or in the short term. The choice is yours.' At the extreme, people may go on 'dopamine detoxes,' avoiding fun activities for some length of time in hopes of resetting their dopamine.

Humans beat AI gold-level score at top maths contest
Humans beat generative AI models made by Google and OpenAI at a top international mathematics competition, despite the programmes reaching gold-level scores for the first time. Neither model scored full marks -- unlike five young people at the International Mathematical Olympiad (IMO), a prestigious annual competition where participants must be under 20 years old. Google said Monday that an advanced version of its Gemini chatbot had solved five out of the six maths problems set at the IMO, held in Australia's Queensland this month. 'We can confirm that Google DeepMind has reached the much-desired milestone, earning 35 out of a possible 42 points -- a gold medal score,' the US tech giant cited IMO president Gregor Dolinar as saying. 'Their solutions were astonishing in many respects. IMO graders found them to be clear, precise and most of them easy to follow.' Around 10 percent of human contestants won gold-level medals, and five received perfect scores of 42 points. US ChatGPT maker OpenAI said that its experimental reasoning model had scored a gold-level 35 points on the test. The result 'achieved a longstanding grand challenge in AI' at 'the world's most prestigious math competition', OpenAI researcher Alexander Wei wrote on social media. 'We evaluated our models on the 2025 IMO problems under the same rules as human contestants,' he said. 'For each problem, three former IMO medalists independently graded the model's submitted proof.'
