What's the term for when people's attention and outrage is directed by an unreliable third party (let's say a partisan news channel) towards certain issues/threats, and away from other equally (or more) significant issues/threats?

I'm not talking about editorial bias. I'm talking about deliberately manipulating audience attention in order to control the perception of reality. Another way of putting it is to create a framework for rejecting or distracting from 'disagreeable' ideas.

For example, a partisan news organization might highlight the purported cultural and economic threat posed by immigration. Since people have a limited budget for their attention, having their attention and outrage focused on immigration might distract from other issues such as rising inequality.
