Paradox Of Choice

Paradox Of Choice

An observation that having many options to choose from, rather than making people happy and ensuring they get what they want, can cause them stress and problematize decision-making.

I am trying to decide on which sofa I want for my living room, I have been changing my mind for a year because there is too many options to choose from. I can't even decide on which company to go with.

    The more similar two options are, the more difficult it is to decide between them, and the less consequential the decision becomes. A rational decider might find herself spending the most time on the least important decisions.

    The Card Paradox

    The Card Paradox

    Imagine that you are holding a postcard in your hand with the words "The statement on the opposite side of this card is true" inscribed on one side. That will be Statement A. The opposing side of the card states, "The statement on the other side of this card is false," when you flip it over (Statement B). A paradox arises when attempting to assign any truth to either Statement A or B: if A is true, then B must also be true, yet for B to be true, A must be untrue. On the other hand, if A is untrue, then B must also be false, hence A must inevitably be true.

    Far as I gather, this paradox relies on A's reckoning as the reliable source, hence we look on the A side first. If we had looked on the B side first, being informed what A side says is false, then there likely be no paradox at all; we would only have been told what the lie was.

    No. As is explained above, the statements are mutually contradictory. If we assume B is true, then A must be false; but if A is false then B must be true, and so on.

    The Paradox Of The Heap

    The Paradox Of The Heap

    A paradox involves a heap of sand from which grains of sand are removed individually. The dilemma is to think about what happens when the process is done enough times that only one grain remains: is it still a heap? Assuming that removing a single grain does not turn a heap into a non-heap. If not, when did it go from being a heap to not being one?

    There was never a heap to begin with. This "not-a-parodox" is reminding us that our definitions are arbitrary. The map is not the terrain. The word is not the thing. The thing is not a word. Truth is unspeakable. The moment it is spoken, it becomes an abstraction. Just like the map is not the terrain. The abstraction is not the truth. Therefor the truth can never be spoken

    Doesn't take time into account. Humans have only had radios for about a hundred and thirty years, so anything outside about a radius of 130 light years from Earth has no way of knowing we're here. By the same token, there's no kind of guarantee that the short time we've been able to detect incoming signals would overlap with the broadcast period of any other intelligent species.

    My favorite answer to this is the dark forest theory. It states that species successful enough to get to the point of space travel are ambitious, curious, and aggressive. Nobody really knows who is the most ambitious, curious, and aggressive, and so they don't want to risk getting on that particular bad side. Just like bunnies hide from foxes who hide from hawks. Nobody wants to wake up a sleeping grizzly, so we tread lightly.

If I worked at the Pentagon, I would show the world some amazing footage of a non-threatening UAP, filmed by a reliable witness and then sit back and assess how the world reacts. There was no martial law or looting, just a world watching in amazement, which was the best reaction possible. Now they can trust us, maybe they'll feel confident enough to take it a step further.

And since we have not yet traveled beyond our own solar system, and our system is admittedly just one of several quadrillion in our galaxy, how do we know whether or not we're the only ones out there.

    The Elevator Paradox

    The Elevator Paradox

    First noted by Marvin Stern and George Gamow, physicists who had offices on different floors. Gamow, who had an office near the bottom of the building noticed that the first elevator to stop at his floor was most often going down, while Stern, who had an office near the top, noticed that the first elevator to stop at his floor was most often going up. This creates the false impression that elevator cars are more likely to be going in one direction than the other depending on which floor the observer is on.

    Yes, in terms of model. For example, a model of an airplane would be the same in model terms (size, shape, type of material). In terms of deeper thought, it wouldn't be the EXACT same because of wear and tear (a boat that has aged wood would be different than a brand-new boat). If it's called the same name, would it be considered the same thing? Depends...

    Galileo’s Paradox Of The Infinite

    Galileo’s Paradox Of The Infinite

    On the one hand, Galileo proposed, there are square numbers. On the other, there are those numbers that are not squares. Put these two groups together, and the total number of square numbers must be less than the total number of square and non-square numbers together. However, because every positive number has to have a corresponding square and every square number has to have a positive number as its square root, there cannot possibly be more of one than the other.

But how does that translate to real life?? If I want to walk from point A to point B, I will just walk and I will definitely reach point B at some point, while checking those "half-checkpoints". Would there be any "halves" left to travel? No, right? Because I arrived at my destination.

It refers to a hypothetical situation wherein a donkey that is equally hungry and thirsty is placed precisely midway between a stack of hay and a pail of water. Since the paradox assumes the donkey will always go to whichever is closer, it dies of both hunger and thirst since it cannot make any rational decision between the hay and water.

One would expect humans to be more likely to get cancer than smaller creatures such as mice. This paradox occurs across all species, too.

    There is a barber who lives on an island. The barber shaves all those men who live on the island who do not shave themselves, and only those men.

Conversely, if the barber does not shave himself, then he fits into the group of people who would be shaved by the barber, and thus, as the barber, he must shave himself.

    A prisoner is told that he will be executed next week at an unexpected day. Then he says, they cannot hang me saturday, for then I will know friday, that I will be hanged saturday. Likewise, I cannot be hanged friday, because I will know it thursday. And so on. They cannot hang me unexpected at all. But in reality, they come wedensday and say, Surprise, we are going to hang you today.

    The Teletransportation Paradox

    The Teletransportation Paradox

    Imagine that there’s a “teletransporter” machine on Earth. It puts you to sleep, records your molecular composition, breaks you down into your constituent atoms, and relays that information to somewhere on Mars at the speed of light. At the receiving end on Mars, a machine recreates your body atom by atom down to the last detail. When that body wakes up, it will have all your memories and all the parts that make you who you are. Now, is the person on Mars still the same person as the one who entered the teletransporter on Earth?

    The workflow will be broken on every single cell. Even if the atoms recombine in the exact same position at the same time, molecules wouldn't hold together because there's no chemical chain reaction brought them to be in their former positions. The consciousness will be null because the electrical impulses cannot be teletransported. The result would be a sudden appearance and a violent spillage of red fluid on the Mars end.

According to quantum mechanics, since we can't see in the box to know if the cat is alive or dead, the cat is both alive and dead.

    This isn't a paradox. The whole point is that a cat can only be either alive or dead, not both. Schrodinger was making the point that things that may be true on a quantum mechanical level, such as the superposition of potential states, don't work in the realm of classical (i.e. macro-scale) physics.

    I'm not sure why they are forced to do anything. You would only increase extraction if there was a market for it. If we have discovered a reliable alternative energy source then the fossil fuel industry will be obsolete because nobody will be buying their product so they won't be making any money. They'll close all the pipes much like they did with coal mines in the eighties in the UK. This sounds to me like fossil fuel industry propaganda.

    To correctly predict the invalidity of this argument, a formalization must capture the fact that the first premise makes an assertion about how the temperature changes over time, while the second makes an assertion about the temperature at a particular point in time.

At the same time, the rope starts to stretch uniformly at a constant rate of 1 km per second, so that after 1 second it is 2 km long, after 2 seconds it is 3 km long, etc. Will the ant ever reach the end of the rope?

    After 1s, ant is 1 cm out of 1 km along. After stretching, BOTH of these numbers increase, so it's now 2 cm out of 2 km. Let's reframe this and look at the ant's position as a part of the whole. Now, the rope will always have length 100,000, and the ant will go 1cm, then 1/2 cm, then 1/3 cm, etc. This is the harmonic series, which diverges. So the ant will reach the end of the rope eventually.
