This is apparently an interview question from Black Rock.
-------------------------------------$
Murders in a field.

You are guarding 100 murders in a field and you have a gun with a single bullet. If only one of the murderers has a non-zero probability of surviving, he will attempt to escape. If a murderer is certain of death, he will not attempt escape.

How do you stop them from escaping.

This question is so interesting so I thought I would give it a go of how I would answer.

I would announce to the prisoners.

That I have a kill switch, if I die the surrounding area is set to explode killing everyone. I walk around with the gun pointed to my head and a rubber band on the trigger finger, meaning if I get incapacitated the gun automatically fires.

I can't tell this solution is stupid, ingenious or completely fucking psychopathic, either way the prisoners aren't leaving.

> The first one of you who attempts to escape will be shot to death.

@Humpleupagus That kind of works but these people are in a group. And that logic has been used before especially war prisoners and a large majority of those people will gamble the fact that they don't have enough firepower to kill everyone on the group if everyone decided to run at once.

Because even if you decide to get 5 to 10 buddies to run at once you could reasonably gamble that at least one to two of you will escape even if it's a modern firearm.

And considering it's only one person unless I'm holding a minigun they will probably gamble that I don't have enough bullets in the magazine to kill all of them.

You're over thinking the question and adding in facts not presented. That's exactly what they're testing for. They want to see if you can stick to the question asked. The performance section of the bar exam tests exactly this. Can you analyze using not background knowledge, but rather using only the information provided. An elaborate answer will lead to a no-hire.

@Humpleupagus oooo, what test is that.

I definitely want to try my luck on some questions from that.

@Humpleupagus @Mr_NutterButter Take the most likable one, hold him at gunpoint, and say he dies if anyone moves.

@Eleutheria2 that's actually a pretty good one but I would like to counter with the fact that all of them are murderers meaning that one of them would be likely to not value his life no matter what and simply let you kill him to escape because presumably these people are narcissistic and extremely likely to be sociopathic meaning they only value their own life and nothing else but that.

@MasterSimper @Humpleupagus @Mr_NutterButter the Chad meme is the best answer, not killing them all... just one. They won't know you don't have 99 more bullets but know you're willing to kill them.
If only one murderer has a non-zero probability of escaping and only under that condition can they attempt, simply shoot them. The fact they are trying to escape is evidence they are the only one who could.

@fireandforget out of the group of 100 murderers you can't tell which one is going to attempt to escape all that you know is that if they even believe that they have a shred of escaping they will attempt it. So you need to install I guarantee of death before they even attempt to escape.

Also Black Rock worded the question odd. It's simply saying that all 100 prisoners have a chance of escaping if they believe that they can

Meaning technically all 100 prisoners could theoretically attempt to escape at the exact same time.

@Mr_NutterButter
Come on, it's Blackrock. They have only one solution for everything.

Tell them, that your rat had informed you about a guy who was planning to escape. Do not mention who the rat is, since you don't have any, and execute the guy who "was planning to escape"

Now, they will no longer be able to plan an escape, since they will be too buissy finding the rat.

@Mr_NutterButter
Or..... you tell them, that the last one standing is free to go.

And off the lucky bastard. But I don't think, that 0% survival rate was the goal.

@LukeAlmighty definitely not the goal, but it's a fun way to think about it...

@Mr_NutterButter my dumb ass can't stop thinking of a guy standing in a field with a murder of crows. I'm too silly for this shit.
