Exactly the opposite.

To read minds, you need to completely quiet your own. Essentially turn it off.

The problem is that once it’s off, if there is nothing to keep it moving (other person’s thoughts), it just kinda stalls.

If two (real) mind readers tried to simultaneously read eachothers mind and there wasn’t anyone else nearby, they would become catatonic until someone who was actually thinking came by which would allow the mind-readers thoughts to move again.

If nobody came by, they’d both eventually die.
