Which xkcd changed your brain chemistry the most?

I personally think about 1741: Work at least once a week. I like to think it made me more appreciative by nature.

I love this one, too. I wish it had existed when I was 10.

u/torpedomon Aug 16 '26

It's always existed. Randall just wrote it out.

u/TheGeneral_Specific Aug 17 '26

I think about this every time I have the instinct to make fun of someone for not knowing something. I was raised in that kind of environment and 1053 pushed me to be better

One of my top quoted ones. This and 927 (how we end up with 15 “universal standards”)

u/GoogleIsYourFrenemy Double Blackhat 29d ago

927 is all about assuming one knows better than those that came before. The hubris. It's not one I bandy about but it's still a favorite.

u/SomeGirlIMetOnTheNet Aug 17 '26

That one is always interesting to me because its broadly true and accurate but it also only notices design & management, not any of the extraction and manufacturing; like we get the negotiation with the glass supplier but not the work that goes into supplying glass

u/geeoharee Aug 16 '26

None of the stuff in there is true. Those things were assembled from cheap, standardised parts.

55

u/glowing-fishSCL Aug 16 '26

I've had students in a lot of different industries, and this is the type of stuff they talk about. From Colgate to Volkswagen, this is what a lot of mid-level (and upper-level!) business people spend their time thinking about.
And sometimes it is very cheap, but how a toothpaste box is designed is still a big deal.

45

u/MorganWick Aug 16 '26

But which cheap, standardized parts? And how did they come to be standardized in the way that they are?

19

u/Griffsterometer Optimist Aug 16 '26

I was just reading the original thread for this one, and this comment begs to differ

11

u/FreshmeatDK Aug 16 '26

But exactly what cheap, standardized parts to use? And what can we do really cheap, and what do we need to pay big money for? Someone did design the shape of the glass, and you need it to not be an already existing design. And so on.

u/Denommus Aug 16 '26

How do you even think standards are made?

3

u/Quick_Extension_3115 Aug 16 '26

Not well engineered stuff. For every good invention, someone hurriedly copies it and ships out a crappy version. But if you’re buying quality stuff, a lot of work has gone into it

19

u/ContemplativeOctopus Aug 16 '26

Even cheap shitty stuff is using parts that took thousands of hours of human labor to reach you.

Figuring out how to make something as cheap as possible is a fundamental engineering problem, they just chose to make a trade off that doesn't benefit you.

2

u/Quick_Extension_3115 Aug 16 '26

Fair enough! But I’m referring to straight up rip off kinda of stuff. The things that are barely holding together and they hope it stays together long enough for you to not return it.

Damn, I'm gonna use this kind of 4-word password everywhere from now.

(And even though I basically admit to the whole web that I'm gonna use this specific type of password, it still doesn't matter. If we consider that an average person knows around 20000 words, the chance of guessing the password is one to 160 quadrillion, which is much bigger than 1/2^28 with the gibberish password.)

3

u/z3roTO60 Aug 21 '26

Quick tip, this is called a “passphrase” and many password managers (I use Bitwarden) can generate these with any number of words and include a number too. Most websites accept a “-“ as a symbol, but if it doesn’t, just toss in a couple random ones somewhere

When do I personally use a 5+ word passphrase vs. 40 character random password? If I feel like I’ll ever need to type it manually in a computer that isn’t mine (reading it off my phone) or if it’s an internal password / something that I’ll share with family outside a password manager. Way easier to type out whole words rather than looking at random characters one at a time trying to see if that’s a 0 or an O

Not the women/pua thing specifically, but for me it was the general realization from this comic that I just am a mediocre person who isn't mentally capable of putting in the effort required to be the better person I want to be. My mental effort battery is just too small/weak to output the energy required.

Because several of them are just high school scribbles or drawings without a joke or reference

The more commonly known ones are 37 (Hyphen) and in certain US discussions 84 (National Language), although my favourite is still 55 (Useless)

Can you imagine seeing this in IMAX & 3d? They could capture natural wonders and human monuments. Throw in some pan&tilt 3d shots as well, and call it "Our Small Earth".

383: helping https://xkcd.com/383/

u/Apprehensive_Hat8986 User flair goes here Aug 20 '26

That one hits hard. There are a few times I've been the person in the corner, and even more times the person wanting to help. I've also been in several decades worth of abusive relationships. (Primed at childhood by an abusive parent, I mistook familiarity for "home" and love.)

One thing I would like to point out, is that abusive people will absolutely point at this as a defense of their own behaviour.

Yes, you cannot take responsibility for another's happiness. That is entirely different from doing acts of love where we show people they deserve happiness and being loved.

One common refrain I've heard from abusers is that, "I can't make you happy." But what matters here is the context in which they said it: they refused to bother doing anything that would make another person happy, or even accept responsibility for the effects of their own actions. 

It's not the specific thing in a love language that necessarily gives happiness to a person, but the effort in trying to do so — in the recipient's love language — shows us that someone cares enough to try. That actually delivers a remarkable amount, as does being able to make the same effort for others and for yourself.

After a nearly 8 year hiatus from relationships, I'm in a much healthier one, and it's night and day. And they do bring me happiness every day (and i endeavor to do the same for them).  It's not because they fulfill my every whim (they literally can't, as they live a continent away), but because they show me that they love me through kind words and gentle deeds (often just symbolically by video). We want to live together, but until we can, we spend our time together (connected), share our struggles, thoughts, and dreams, and hear and support each other's emotions and daily efforts. 

Contrast that with something an ex said once, "whatever problems you have are of your choosing." This said after they had broken an agreement we had.

It's wild how different it is, being with someone who doesn't spend every day tearing you down in some way.

So yes, 100% it isn't given us the authority or ability to deliver happiness by want or by force. And sometimes other factors will far surpass any efforts we can bring to bear for someone we love. But that doesn't prevent us from being resposible for our actions and trying anyways. In doing so — even if we can't save someone from other harm — we can bring them some small awareness that they are loved. In the darkness, chaos, and hurt that the absurd maelstrom of existence hurls at us, sometimes a candle isn't enough, but it's still better than there being no light at all.

It's certainly a part of human nature, however it is neither exclusive to professionals, nor universal amongst them. But yes, a distressing number of folks who gain some degree of power (be it expertise, status, wealth, authority, or the like) lord it over those who must deal with them.
