If they fail they should be partitioned from society and monitored until counceling brings them to mental stability.
I’m seeing mental problems everywhere; in person and online (name your social media). Most people are clearly mentally unhealthy, they are polarized, sociopathic, delusional, depressed, etc crossing way passed unsafe levels, and we just let them crawl around society.
Now we all can verify that mental problems are increasing rapidly but the numbers would be much higher if they actually were all reported.
I’m going to leverage my connections in society to push a bill to make this reality

Who defines what “mental stability” is, and how is this not just a tool to throw undesirables in camps?
its about mental illness or mental health.
same as physical sickness and health.
How does psychology diagnosed mental illness right now? Same techniques
A diagnosis is not the same thing as mental instability. You can have a mental illness that is stable and not be at significant risk of decompensation.
That’s what the evaluation is for. To see who is unstable. Sigh
So each evaluator is independently deciding whether someone is stable based on vibes noted during the “pass or be detained” evaluation?
Just look at the US Dept of Health to see what can happen when anti-science ideologues get this kind of power.
