I used to work with someone whose friend was a researcher on the Nikki BB series. She didnt pass the psych tests (totally failed them, they knew she was unstable) but they put her in for entertainment value. Really awful and manipulative (shock - TV show prioritises viewing figures over individual well being) I found this out about 2006? - I couldn't watch BB after that.Yes, she had already spent multiple times in hospital due to anorexia. HOW she passed the psych tests to get in that year (and Lea, and Shabaz for that matter) I’ll never know. (I mean, I know you can fake not being ill but I thought the whole point of those sorts of tests were that they were vigorous and meant to weed out that sort of fakery).
Any other reality show I watch with that format - Love Island etc - it's always in the back of my mind.
