| Off topic but of all the Mooney images ever made, why a scary clown? That aside, working with complex systems and constraints there often isn't an aha moment, there's just a decision to be made. As someone who loves that aha moment, I can get stuck trying to figure out perfect from good enough. Interesting to see there is indeed a positive emotion correlated with that aha moment that keeps people searching for solutions. I wonder if there's a correlation between addiction and this aha moment. Like you get drunk and suddenly "aha!" those big unresolvable problems don't matter. The next morning they matter again until, aha, beer:30 hits. |

I've been chasing that epiphany dragon for decades and so has everyone else in the shop. Ever feel like you've got one foot out the door once you comprehend the systems you work with? | | | |
| ▲ | ants_everywhere 10 hours ago | parent | prev [-] | | > working with complex systems and constraints there often isn't an aha moment You only get the a-ha moment when there's essentially one discrete piece of information needed to decide between alternatives. That doesn't apply to most problems. Your brain simultaneously assigns probabilities to possible solutions, and in certain cases there's an information update that sets one solution to probability 1 and the others to 0. If your brain is actively expending energy keeping these possibilities warm simultaneously, then this will naturally lead to a rapid change in energy which will feel like something because it's a change in the flow of neuro chemicals. It's not obvious that it would feel pleasant. But since the nucleus accumbens is active during problems solving then it's not entirely surprising that the the NAc gets extra stimulated in the rush of energy as the probabilities collapse and weights get updated to the real solution. But relatively few problems require you to simultaneously juggle multiple possible solutions and pieces of evidence that are brought together in a single instant. So chasing that feeling is generally a poor strategy. |

| The little puzzle the article opens with is fun, but solving it is not what I'd associate with an "aha" moment. To me it felt more like a brute force search, or like solving a Wordle puzzle. I consider "aha" more creative, like recognizing that key insight that crystalizes a solution to a problem you're working on. (Or maybe a pattern or analogy that cleanly collapses a swath of the complexity). |

| "Hare Brain Tortoise Mind" is a great book that goes into how this works and how to work with/against it. https://www.youtube.com/watch?v=aB_4YU6UtCw tldr: There is a background, non-verbal process in your brain that has the advantage of a larger working set size than your foreground verbal thinking. It is able to observe and consider more stuff at once and find associations better than your conscious thought process. But, it has several disadvantages. It takes time to do its processing. You can't will it into action. It communicates non-verbally with your foreground process. It doesn't work under pressure (thus the need for relaxed, unfocused time). The non-verbal understanding is difficult to deconstruct, generalize and reapply. It can lead to you solving a problem, not understanding how and not being able to solve a variant of the same problem. So, the general recommendation is: If you have a complex problem to solve, first absorb as much information about the problem as your brain can hold. But, do not try to solve anything. Then, go take a break. A walk in a natural environment is preferable. Don’t think about the problem. Relax in a low stress environment. Let your background brain have a chance to chew on it and maybe bubble up some suggestions. |

| ▲ | markussss 4 hours ago | parent | prev [-] | | Thanks for the link and tl;dr, even though it's a quite short video (3:16). I found your explanation very interesting because I have intuitively felt like this is accurate, but never knew what the underlying process is. I have been following this for years already, first absorbing information about anything where I need to make a decision, and then just leave it to stew in the back of my mind. And after a while the answer just appears in my mind, without me really understanding where it comes from. | | |

Here are three words: pine, crab, sauce. There’s a fourth word that combines with each of the others to create another common word. What is it? YXBwbGU= (Use Base64 Decoding)

| ▲ | whatevertrevor 10 hours ago | parent | next [-] | | I've played enough NYT connections that this was immediate for me, at the expense of the promised "Aha!" moment. :D | | |
| ▲ | RheingoldRiver 8 hours ago | parent [-] | | Interesting haha, I've played enough NYT connections that I would never have gotten it on my own because when I thought of the correct word with sauce, I thought "_ crab" ? no, can't be that... | | |
| ▲ | whatevertrevor 8 hours ago | parent [-] | | Haha, I know what you mean! Though in fairness, Wyna Liu isn't beyond throwing in a "mostly works" category from time to time... Wild tangent incoming... One instance that recently bothered me with an NYT puzzle was the crossword clue (3 letters): "Chromebooks, but not MacBooks". The answer was "PCs" which doesn't make sense to me under any level of categorization for PC. If we go narrow/historic, then it means x86 IBM PC derivatives which eliminates a lot of chromebooks. If we use the "home computer" interpretation, then I think it's unreasonable to except Macbooks from the PC umbrella. If we go literal, well then everything is a PC, including smartphones, tablets, smart devices. The only reasonable test seems to be "Can it play Doom?". :D Using PC in a "every consumer computing device but Mac" probably made sense in the 80s/90s, now it seems to dilute the term to the point of confusion. I have personally never thought of a Chromebook as a PC, given that it ships with an OS incapable of many things people generally associate with PC activities. | | |
| ▲ | woolion 5 hours ago | parent [-] | | It seems to me that it's exactly why I don't like word games.
They use words like "combine", but it's generally mixing abstractions or taxonomies. To guess it, I looked at 'crab' because it's a quite uncommon that has some deep relationship with a few words only. Then checked the most obvious one (which was the solution) against the other words, and determined that it didn't bear any significant relationship to the third word. So I checked the other (less obvious) potential solutions, and after a frustrating lack of match, I gave up. And then got annoyed that the first candidate was the right one. To be fair, I guess it's partly because I'm an ESL, as I think that solution/sauce can be used as a nominative locution enough to form a "special relationship". To be a designer, you have to play with people's (as in general crowd, not individuals) general understanding of the subject.
In particular, that means avoiding the curse of knowledge, and yes for normal people PC meant "not Apple consumer product".
So ultimately, the search algorithm includes: - categorize all relationships between words, ranked by strength - compare with what is expected to be known in popular culture (adjust ranks) - match against the designer's expectations of similar problems (look for clues to pick a best match) It's a lot of words to say it's the opposite of a aha moment, the result of a pure computational problem, that is often quite frustrating. Thank you for coming to my TED talk. | | |
| ▲ | whatevertrevor 5 hours ago | parent [-] | | I totally get that, I am ESL too, and I have a similar approach for English-based word games. And yeah that often results in mild disappointment or frustration instead of an "Aha!" moment. Actual puzzle video games fair better for me at that aspect, as they avoid the inevitable subjectivity of natural language. |

| ▲ | opan 10 hours ago | parent | prev | next [-] | | I went from thinking this was too hard to guess on the fly to suddenly getting it within a minute or two. Interesting. If anyone wants an additional hint, the word you plug in here isn't put in the same spot for all three words. | |
| ▲ | geuis 11 hours ago | parent | prev [-] | | Please, just provide the answer. Maybe it's obvious but to people like me all I can think of is recipes for butter sauces for crab legs involving pine nuts. Which actually sounds quite good. | | |

| Is there a single repo that has all of these "aha" images? I could see the clown right away, and the vines/plants in the 2nd example were what I thought first but organic shapes are harder to be sure about. That also brings to mind that first exposure to this dataset affects the effectiveness of the rest of the dataset. If you're doing initial exposure, you'll definitely get the "aha" moment. But if all of the images in the dataset are of the same type, your brain quickly learns the pattern and the "aha" moment vanishes. If they did their study on all of the images per test subject, the results after maybe the first 5 are basically useless for any definitive conclusions. |

| What are other words for “aha”? Is it also called serendipity? |
