I'm pretty sure anyone from the healthcare field recognizes
this effect.
Take an elderly man with poor health literacy. Add a stressful situation. Try to give him information about healthcare facts. Watch as those facts get mixed up inside his head and come back out in completely the wrong way.
UV light and disinfectant can be used to sterilize contaminated surfaces. Unfortunately, this old man confused that with using them in infected patients. Not a big deal when you're able to just correct the old man's misunderstanding. Very hard when the old man happens to have a pulpit to share his poorly understood information without any filters to a bunch of other stressed people with poor health literacy.
