This is not only the age of 'fake news', but more importantly the age of people publishing things, be it in the media, or 'just' on a forum somewhere on the internet, without knowing what they are talking about or doing a minimum amount of research beforehand. Thats why I wrote a few posts ago that all this talk about the 'shocking revelation' that Boeing is 'withholding information' about MCAS is absolutely silly - especially since we still don't know what happened to this particular plane.
And, here's an interesting study from the FAA site on Line Pilot Performance of Memory Items for 737CL and NG pilots with 16 line pilot volunteers. One of the test cases was runaway stab. Salient results below (which would seem to validate QRH to some extent):
Four pilots made commission errors in the completion of the runaway stabilizer trim checklist by attempting to activate the electric trim switches in the direction opposite the runaway. One of those four pilots stated that he would also attempt to engage a different autopilot in the hopes that it would not experience the same malfunction (Figure 3).
Control column.....................Hold firmly
Autopilot (if engaged)...........Disengage
> Electric trim in opposite direction
> Engage other autopilot
If runaway stabilizer continues:Trim cutout switches...............Cutout
Trim wheel.....................Grasp & hold
