> Interestingly, the article makes no mention of the followup experiment where it seems a hospital invited a repetition and then claimed to have found 40 or so fake patients during the agreed period.

The reason is simple. This article is pure propaganda along the lines of the book "The great pretender" by Susannah Cahalan.

The experiment might have flaws, but this second part is conclusive and no critics ever address it.

This is just another brick on the long propaganda road to a destination that is very worrisome.
