Trump’s cognitive exam contained its own test for journalists | Paul Chadwick

The president's dementia assessment and other specialist tests are available online, but the media must present them with care

President Trump's recent medical examination was partly theatre: the doctor's white coat, the "good genes", the superlatives that seemed prescribed. But it was also serious. This commander-in-chief can personally initiate nuclear war. When the Guardian turned the theatre into audience participation, some readers were troubled. The episode illuminated a recurring aspect of life under the internet - information previously known and used only by specialists is now available for use by almost everyone, without expert understanding of the purposes and limitations of that information. This can discomfort specialists and challenge journalists, who will often be the bridge between experts and a general audience.
