Yes, I understand that if you make the assumptions that I laid out, then it is advantagous to switch. I'm not confused or bafffled by the problem. The simulation you linked to is predicated on those assupmtions.

But I don't think those assuptions are intuitive based on how the problem is usually presented. At least they are not intuitive for me. Here is the famous Ask Marylin column that popularize the Monty Hall problem;

Suppose you’re on a game show, and you’re given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say #1, and the host, who knows what’s behind the doors, opens another door, say #3, which has a goat. He says to you, "Do you want to pick door #2?" Is it to your advantage to switch your choice of doors?

When I read this, I think that the host is potentially a trickster, or possibly he was waiting to see what I chose before he gave me the choice. I don't view him as a mechanical device that must always open a door that I did not open and that has a goat.

If you think that it is intuitive to say that he always opens a door that the contestant did not open and that the door he opens must contains a goat, then I suppose the result would seem really cool. I don't share that intuition, and so the result seems cheap and misleading.

I know that a lot of people have big issues with the Monty Hall problem, and I believe it is because it is usually explained in a misleading way. In order for switching doors to be advantageous, we must assume

1. That the host always opens a door that the contestant did not open, and

2. That the door which the host opens always contains a goat.

To me, these assumptions seem counterintuitive.

If he is a game show host, couldn't he be trying to trick you, and only open a door when you first pick the door with the car? If this is the case, then the host opening a door means there is a 100% certainly that the original door you picked has the car.

If he is trying to build suspense, wouldn't he open the door with the car behind it 1/3 of the time? If this is the case, then him opening a door with a goat means the remaining doors have equal chances.

Maybe the host has some other set of rules that he follows that we don't know. Maybe he opens the door with the car if you have red hair and the door with a goat if you have blond. I just don't know why we should assume that he always opens a door and that his door always has a goat.

If I were playing the Monte Hall game, I would flip a coin and on heads I would change doors, on tails I would not. This way, the host's strategy is irrelevant; I will always have a 1/2 chance of winning.

Different people left reddit for different reasons. The censorship issue is just one that I find interesting and I didn't know what Snapzu users thought about it. I agree with you about the repetitive banal conversation, but I don't agree about the constant tantrums from the mods. I sympathize with them way more than the admins in the blackout.

Personally I left reddit because there was no serious back and forth between the admins and the users. No new mod tools, despite mods clamoring for years. Most of the developments the admins pursued were just weird and not really what the users wanted (as far as I can tell). Victoria being fired is fine, she was an at-will employee, so reddit inc. can fire her whenever they want, but not telling the /r/iama mods that she had been fired, and not having a backup plan is just ridiculous. Here's one concrete example of the administration not understanding the website; Ellen Pao attempted to link to a private message in her own inbox. Obviously no one could see it, and yet the post got gold, presumably from Pao. This final example by itself is not really a problem at all, it's just funny. However, I think it is indicative of how little the people running reddit understand the site.

Of course people are free to disagree with my opinion, but the lack of communication was what really irked me. What I like about Snapzu is that I've made literally 2 posts and I've already had interaction with an admin.
