teens and twentysomethings today are of a very different demographic and have markedly different media consumption habits compared to Wikipedia’s forebears. Gen Z and Gen Alpha readers are accustomed to TikTok, YouTube, and mobile-first visual media. Their impatience for Wikipedia’s impenetrable walls of text, as any parent of kids of this age knows, arguably threatens the future of the internet’s collaborative knowledge clearinghouse.

The Wikimedia Foundation knows this, too. Research has shown that many readers today greatly value quick overviews of any article, before the reader considers whether to dive into the article’s full text.

So last June, the Foundation launched a modest experiment they called “Simple Article Summaries.” The summaries consisted of AI-generated, simplified text at the top of complex articles. Summaries were clearly labeled as machine-generated and unverified, and they were available only to mobile users who opted in.

Even after all these precautions, however, the volunteer editor community barely gave the experiment time to begin. Editors shut down Simple Article Summaries within a day of its launch.

The response was fierce. Editors called the experiment a “ghastly idea” and warned of “immediate and irreversible harm” to Wikipedia’s credibility.

Comments in the village pump (a community discussion page) ranged from blunt (“Yuck”) to alarmed, with contributors raising legitimate concerns about AI hallucinations and the erosion of editorial oversight.

People aged 14 to 20 are more often being diagnosed with psychotic disorders, including schizophrenia, compared with those born earlier, a large Ontario study examining 30 years of data suggests.

To conduct the study, published in Monday's issue of the Canadian Medical Association Journal (CMAJ), researchers looked at health administrative data from more than 12 million Ontario residents born between 1960 and 2009 to look for cases of a psychotic disorder.

In the Ontario study, those diagnosed with psychotic disorders not linked to mood disorders, such as schizophrenia, were more likely to be male, live in low-income neighbourhoods, be a long-standing resident of Canada and have received care for mental health disorders and substance use.

Why isn't known. Myran and his co-authors suggest several possible reasons for the increases: older parental age, socioeconomic- and migration-associated stress and an increase in some negative childhood experiences like abuse in more recent decades.

Myran said there likely isn't a single explanation, but he called substance use — including cannabis, stimulants, hallucinogens and synthetic drugs — a leading possibility contributing to the rising rates over 20 years.
