experts say 

A way to cover up bullshit by making the broad statement, "Experts say", then the bullshit.
As nobody has any idea which experts they were referring to, or what level or expertise they had, it is a great way to cover up not having a distinct source for the information.

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.
