experts say
A tired trope that is used in hundreds of headlines a day. The phrase that journalists deploy to be able to say whatever they want, without the need for proper sources. Most of the time, this phrase is used in the headline, or one time in the body text, without said experts ever being identified or mentioned again.
Example:
"Experts say that eating your own shit could lower your risk of proper digestive function. Here's why." - CNN
