What is the Goldwater Rule and how is it applied in modern America?

What will be an ideal response?

When Barry Goldwater was running for president in the mid-1960s, a magazine placed him on its cover and suggested that he was psychologically unfit to be president. Goldwater sued the magazine for libel. In 1973, as a result of the Goldwater incident, the American Psychiatric Association created the Goldwater rule, which prohibits psychiatrists from offering diagnostic opinions on people they have never professionally examined. The Goldwater rule was brought to the forefront and challenged when, in 2017, 35 mental health professionals signed and published a letter questioning President Donald Trump's mental health and fitness for the presidency. Professionals today suggest that the Goldwater rule should be reformulated as the Goldwater Guideline, so that it complements "the duty to inform."
