Signal awareness of people who are face blind or otherwise had trouble with CRT or RME

We get a lot of reports of issues like faceblindness etc. I wonder if we can just say "try anyway" or if we should have an option for it.

Personally, I think this is the point — we are trying to test if they can see emotions in eyes... but I'd rather reduce peoples concerns somehow.
