The best way to learn to spot a conspiracy theory is to make one yourself.
Pick a real news story. On the next step you'll choose who's behind it and why. Then walk through the four moves real conspiracists use, with a debunk on every step.
Choose whichever real-feeling headline your imagination will run wildest with. Don't overthink it.

An annual YouGov-Cambridge Globalism Project survey, reported by The Guardian, finds that support for populist ideas has fallen across several European countries over the past three years. The survey measures attitudes like distrust of elites, favoring strong national control, and opposition to immigration. In the latest cycle, populist sentiment declined in ten European nations, indicating fewer people now express broad populist beliefs than in earlier years.

Two new studies presented at the European Society of Cardiology’s annual meeting found links between consuming ultra-processed foods and higher risks of heart disease, including heart attacks and strokes. Ultra-processed foods are widely available consumer items such as fizzy drinks, many breakfast cereals, packaged snacks and ready-made meals. One analysis reported that a 10 percent increase in daily ultra-processed food intake was associated with about a 6 percent rise in risk of cardiovascular disease.

Scientists and doctors point out that many health problems run in families, and the diseases now affecting older baby boomers can offer a warning about what people might face later in life. Advances in DNA sequencing make it possible to find gene variants that raise the chances of heart disease, diabetes and some cancers. Identifying those risks early gives doctors and patients options for monitoring, preventive treatment and tailored medical care.

Scientists and conservationists are debating de-extinction, the idea of bringing extinct species back using modern genetic tools. Advances such as PCR, genome sequencing and gene editing have made it technically plausible to reconstruct genomes from preserved DNA. Companies like Colossal Biosciences aim to use these methods to create proxy woolly mammoths by editing Asiatic elephant DNA. Proponents argue such projects could help restore lost ecological functions and biodiversity.
