Is there a house advantage in a "double-or-nothing" coin flip game?

The idea is that if the coin flip goes in the player's favor, they win double their bet. After winning, they can either collect their winnings, or risk them all on another coin flip to have a chance at doubling them. The initial bet is fixed at, let's say $1.

Mathematically, this seems like a fair game. The expected value of each individual round is zero for both house and player.

Intuitively, though, I can't shake the notion that the player will tend to keep flipping until they lose. In theory, it isn't the wrong decision to keep flipping since the expected value of the flip doesn't change, but it feels like it is.

Any insight?

Is it actually very common for people to have violent sadistic fantasies, possibly involving actual people in their lives?

I just kind of wonder with how casually people express these thoughts. It's a little disturbing how normalized it is to entertain such notions, given how other types of fantasies are very stigmatized.

Like when discussing char.ai, acting out sexual or romantic fantasies is something a lot of people do, but it's considered embarrassing. While people freely discuss violent roleplays without any shame.

And then there's the cliche of fantasizing about killing one's boss or coworkers.

Are these really common thoughts for mentally sound people to have?

Small children are well known to be afraid of voids (closets, under the bed) in their sleeping area. Knowing this, why don't we design children's rooms to eliminate them?

I'm not a parent, but going by pop culture, it seems like literally every child has the same fears.

In pre-modern times, I imagine that they'd be sleeping in the same room as the parents, but if modern notions of privacy don't permit that, seems we could at least design an enclosed capsule or something.

Meta- Community input requested on the rule to state which country you're answering for when you reply to a post

I really don't want to be overly strict with the rules, especially while this sub is so small. But I think this is an important rule, and I'm considering being more strict about its enforcement.

The reason I think it's important is that this is meant to be an educational community. In many cases, I assume people don't say where they're from because they assume it's obvious to people based on their answer. It may be, to people from the US or familiar with its zeitgeist. But this community isn't just for them. The last thing I want is for this community to suffer from US-defaultism.

For that reason, I'm thinking that from here on, if I see an answer that doesn't state which country it's for, I'll give a reminder. After that, the poster will have 24 hours to edit it into their post, and it will be deleted if they have not done so.

What do you think? Too strict? Not strict enough?

What do you do to protect your car from the sun?

I always try to find a shady parking space whenever I need to park for awhile. I have a steering wheel cover, which is a lifesaver. Sometimes I think about getting one of those boards you put on the windshield, or even a full reflective car cover, but I'm not sure if that would be worth it.

I also tend to worry that parking in the sun is bad for my car battery (I have an EV.) Are there any grounds for that worry?

Ask The World - A non-regional community for asking questions about other countries and cultures

Ask The World

![email protected]

Back on reddit, I really enjoyed participating in the various "Ask " subs, so I'd like to get something similar started here. This community is going to be for general questions for anyone from any country, not directed as a specific country. Ask about culture, lifestyles, geography, whatever you want to know that might be different in a different place.

I hope some of you will be interested. I'd really like to see Lemmy grow in general.
