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.
Or trying to decide the box of cereal you want next, whilst in the cereal aile.

Paradox Of Hedonism
If you seek pleasure or happiness for the sole purpose of achieving it for yourself, you will fail. Instead, you must pursue other goals that will bring you happiness or pleasure as a side-effect.
Happiness (or Contentment, which I believe is what is really meant) is not a pleasant sensation but rather a solid idea.
Fredkin's Paradox
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.

Intentionally blank page paradox: Many documents contain pages on which the text "This page is intentionally left blank" is printed, thereby making the page not blank.
Catch-22
Pilots who are psychologically unfit can bail out of combat duty, but anyone who attempts to do so establishes his sanity.
Although this is only one example of Catch-22 in action; as becomes apparent later in the book, the exact wording of Catch-22 is unknown but basically reads "f**k you, the army does what it likes"
From what I understand the paradox is that the only way to prove you're unfit is to WANT to go to the battlefield because no sane person would. But if you want to go then they'll just let you.
Pinocchio Paradox
What happens when Pinocchio says "My nose grows now"? Basically, his nose would have to grow to make Pinocchio’s statement not a lie, but then it can’t grow otherwise the statement would not be a lie.
Prince Charming: You! You can't lie. So tell me, puppet... Where... is... Shrek? Pinocchio: Uh. Hmm, well, uh, I don't know where he's not. Prince Charming: You're telling me you don't know where Shrek is? Pinocchio: It wouldn't be inaccurate to assume that I couldn't exactly not say that it is or isn't almost partially incorrect. Prince Charming: So you *do* know where he is! Pinocchio: On the contrary, I'm possibly more or less not definitely rejecting the idea that in no way with any amount of uncertainty that I undeniably... Prince Charming: Stop it! Pinocchio: ...do or do not know where he shouldn't probably be, if that indeed wasn't where he isn't. Even if he wasn't at where I knew he was, that'd mean I'd really have to know where he wasn't Come on, we all thought it

Grelling–Nelson Paradox
A word that does not describe itself is heterological. Does "heterological" describe itself?
This word does not describe itself. However, the definition describes the word.
By not describing itself, it would be heterological and therefore describe itself. That's the paradox.

The Stability–instability Paradox
When two countries each have nuclear weapons, the probability of a direct war between them greatly decreases, but the probability of minor or indirect conflicts between them increases.
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.
Or 'This sentence is true' . If you consider it true, then its true. But if you consider it false, then it is false.
This is perhaps the paradox to end all paradoxes. Kurt Godel encoded this as a mathematical expression, and published a paper on it. It was a Trojan Horse designed to p**s of the mathematicians. He succeeded in thoroughly and completely destroying the field of mathematics forever. He proved that maths can never be proved. It requires an act of faith. LOL
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.

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?
I kinda understand this one. I have a whole cabinet in my mind with several terms for situations like this. Mountain>Hill>Heap>Pile>Bunch>Handful>Bit>Tad>grain.
But the removed grains form a different heap unless you magically disappear them.
To whoever compiled this thread: Is it a paradox that half of these 'paradoxes' are not, in fact, paradoxes? The answer - which you would know if you gave anything more than a passing care for paradoxes - is NO. But don't let that stop you from including it in your next 'paradox' list, will you. Yes, I'm jolly cross. Off for a lie down.
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
No–No Paradox
Paradox consists of a pair of statements, each of which ‘says’ the other is false.
That describes most religions. If everyone else is wrong, except you, then everyone is wrong
This isn't a paradox. One of the two is false. The paradox looks like this: 1. Statement 2 is false. 2. Statement 1 is true.
Usually you need a 'third' statement to solve anything including the paradox.
The Willpower Paradox
The idea that people can perform tasks more effectively by focusing less directly on doing them, suggesting that direct intentional effort is not really necessarily the most effective approach to achieve a goal.

Fermi Paradox
There should be many alien civilizations in our galaxy if there is nothing particularly special about Earth. We haven't discovered any proof of extraterrestrial intelligent life, though.
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.
Accounting for time spent travelling the usual distances in space the signals might well come from a civilization already dead. And anyone keeping a close eye on planet earth might right now be witnessing an epic battle between a T-Rex and a Triceratops, doing a research for an essay on the secret life of terror birds, or watch the giant pyramid of Giza being built.
Load More Replies...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.
I think that's an excellent theory. Extra kudos for mentioning foxes and bunnies.
Load More Replies...There either is intelligent life out there or there isn't. Both are equally terrifying
We may already have proof. The fact that the Pentagon was so eager to show us the 'tictac' video might suggest that they have something more to say on the matter. 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.
But that supposes that there is not anything particularly special about Earth, and thus is untrue. No, not our Gods, but oxygen and carbon building blocks.
Honestly? All this means is that none of those other "intelligent lifeforms" has yet made it into our (extremely limited, by NASA's own admission) detection range. 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. There could be dozens, if not hundreds of thousands, of other planets where their scientists are having the same discussions and ponderings.
We simply don't have enough data, the Fermi paradox is based on that incomplete data. It's a best guess. The only thing it proves is that we need more data
How do you know we haven't discovered anything? Simply because it's not been announced?
Paradox Of The Court
A law student agrees to pay his teacher after (and only after) winning his first case. The teacher then sues the student (who has not yet won a case) for payment.

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.
So it's more of a mindset. Things seeming like they're against you all the time, even when you have a 50/50 or so chance.
I’d have thought the paradox was calling it an “elevator” when it’s actually descending.
The Coastline Paradox
If you were to measure the coastline of a country by using a ruler on a globe, you would come out with a vastly different number than if you were to pace around the edge. The closer you look, the more wiggles and squiggliness you come across and instead of converging on a more accurate length, the coastline just keeps getting longer. The smaller your ruler, the longer it gets.

No paradox here either. Nothing is ever the same again. Ever. The only thing that is constant, is change. Now, that's a paradox 😎
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...

Dr who explains this so much better (and with kick @$$ music too) x
I like this, I think it's a good one. But if we can show no evidence that time travellers have ever visited us, then that would suggest that time travel will never be achieved. Ever.
Or it may suggest that we're just not that interesting. Imagine the wonders of the future. Would you really leave all that and return to this backward time? If anything you would go forward in time, not backward.

Most people's friends are more socially connected than they are.

However, if it (the probability) IS itself (the case), meaning it cannot be a probability. (It becomes the main fact).
The Sleeping Beauty Paradox
The Sleeping Beauty problem is a puzzle in decision theory in which whenever an ideally rational epistemic agent is awoken from sleep, she has no memory of whether she has been awoken before. Upon being told that she has been woken once or twice according to the toss of a coin, once if heads and twice if tails, she is asked her degree of belief for the coin having come up heads.
Also, you should never really 'kiss' someone awake. There's all sorts of consent issues and some people can be quite violent if awoken by another in close proximity. I thought I was being romantic but my wife obviously saw me as a threat and bit me. My nose will heal but I'll let the dog wake her from now on. At least the dog can bite back.
Cantor's Paradox
The set of all sets would have its own power set as a subset, therefore its cardinality would be at least as great as that of its power set.

The Dichotomy Paradox
To get somewhere, you must first travel halfway; after that, you must travel the remaining distance in halves, and so on endlessly. Thus movement is not possible.
This does not make sense to me. I understand it's like when you start at 100 and keep dividing the products by 2 (100/2=50 - - 50/2=25 - - 25/2=12,5...) it's unclear when you reach 0, at least that's what it reminds me of. 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. Is the paradox that it's unclear when I reach point B or I shouldn't be able to reach B, when in fact it is very possible for me to reach B?? Help
Because then you're always "halfway there." I think I actually use this "paradox" exercise. The "Moving The Goalposts" Paradox?

The Boy Or Girl Paradox
Consider a situation where there are two kids in the family, one of them is a boy. What is the chance that the other child is a boy, then? Given that there can only be one other child and that there are fairly similar odds of having a boy or a girl, the logical response is that the probability is 1/2. However, the possibility that the other child is a boy must actually be 1/3, not 1/2.
Peto’s Paradox
Biologist Richard Peto noticed in the 1970s that mice had a much higher rate of cancer than humans do, which doesn’t make any sense. Humans have over 1000 times as many cells as mice, and cancer is simply a rogue cell that goes on multiplying out of control. One would expect humans to be more likely to get cancer than smaller creatures such as mice. This paradox occurs across all species, too.
But mice don't live as long as humans. Therefore, they don't need as strict protection against cancer because it won't shorten their lives that much.
The Barber Paradox
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.
The barber cannot shave himself as he only shaves those who do not shave themselves. Thus, if he shaves himself he ceases to be the barber. 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.
There's a very easy solution to this paradox - hire a female barber.

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?
There is a great short story, and Outer Limits episode about this.
Star Trek has taught me that you would need a Heisenberg compensator for this to work.
No they are not the same. There is a philosophical question "next year will you still be the same person". Most would answer yes, but it would be impossible to be the same.
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.

The Schrödinger's Cat Paradox
This paradox states that if you put a cat in a box with a poison that might kill it, at the end of an hour the cat has a 50% chance of being alive, and a 50% chance of being dead. 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 thought it had to do with certain forms of energy being either waves or particles, depending on the observer. The unobserved cat is neither alive or dead, the unobserved energy is neither particle or wave?

The owners of fossil fuel resources are forced to increase resource extraction, which in turn intensifies global warming, as a result of an environmental policy that continually becomes greener.
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.

Ant On A Rubber Rope
An ant starts to crawl along a taut rubber rope 1 km long at a speed of 1 cm per second. 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.
The False Positive Paradox
A test that is accurate the vast majority of the time could show you have a disease, but the probability that you actually have it could still be tiny.
If the test is 99.5% accurate, your chance of having an incorrect result (that is false negatives plus false positives) is 1.5%. I think that you don’t understand probability.
I think the point is that if you have a test that is 99.5% accurate for a disease that there's only a 0.1% chance of catching, then the 0.1% chance is independent of whether or not you fall within the test's 0.5% error margin. Which is...kind of obvious.
Load More Replies...The Prevention Paradox
For one person to benefit, many people have to change their behavior – even though they receive no benefit, or even suffer, from the change.
IDK how wearing a mask is "suffering". Also, wearing a mask helps protect you AND other people.
At first I thought they were talking about the magazine named Prevention.
The Birthday Paradox
There is a better-than-even chance that at least two of the 23 people in a room share the same birthday.
Yeah, I agree. I'm bored by the false hope and missed opportunity of this thread. If you stick with it, let me know if I'd made the right call please. Thanx
Load More Replies...Lazy Bones Paradox
Everything that happens is destined to happen. If I am ill and it is my destiny to regain health, then I will regain health whether I visit a doctor or not. If it is my destiny to not regain my health, then seeing a doctor can't help me.
Also works with criminals: The criminal claimed they had committed the crime only because the interactions between the atoms in their body, following the laws of physics, caused them to. The judge claimed that the laws of physics caused THEM to send the criminal to jail.
The Low Birth-Weight Paradox
It is a paradoxical observation relating to the birth weights and mortality rate of children born to tobacco smoking mothers. Low birth-weight children born to smoking mothers have a lower infant mortality rate than the low birth weight children of non-smokers.
Smoking causes low birth weight via a different and less morbid mechanism from other causes, obviously
The Prisoner's Paradox
Two people might not cooperate even if it is in both their best interests to do so.
It's the Prisoners Dilemma, not the Prisoners Paradox. And it's a Game Theory thought experiment that deals with analyzing and predicting the actions of rational agents; not a paradox...
Lombard's Paradox
When rising to stand from a sitting or squatting position, both the hamstrings and quadriceps contract at the same time, despite their being antagonists to each other.
The Observer's Paradox
It is a situation in which the phenomenon being observed is unwittingly influenced by the presence of the observer/investigator.
Some good info here! A few of these could use better explanations and quite a few others aren't actually paradoxes, but it's a good start on the topic.
All of these are actually interesting, but not all are paradoxes. Some are variants of each other. Also some are presented incorrectly because the author didn't actually understand them.
Really, no Hotel Hilbert, which contains a number of paradoxes; including, there is a limit to infinity, and that there is a number larger than infinity.
