Fed Funny

This article from Reuters gave me a great chuckle:

The U.S. Federal Reserve's dwindling confidence in its own outlook and resulting confusion among investors are creating a policy problem that may require chief Janet Yellen to lay out her own views more forcefully.

The article says this about Yellen:

A self-described consensus builder, Yellen sees her job as reflecting the whole committee's views rather than setting an agenda for others to follow.

The article says later:

At Wednesday's quarterly news conference Fed officials' doubts were in plain view, with Yellen using the term "uncertain" or its variations 13 times, more than twice as often as in March. In December, when the Fed raised its rates by a quarter point for the first time in nearly a decade, that word only came up twice.

This presents the following dilemma: How does one say "I don't know" more forcefully?
