Social media ironically has made it harder to actually socialize with people and imo is responsible for a huge portion of social anxiety around the world.

很讽刺的是，社交媒体反倒让人们与他人交往更困难了，我认为社交媒体世界上大部分社交焦虑的罪魁祸首。

The issues caused by social media are much deeper than just lack of in-person connection and social anxiety. Mental health overall in teens and young adults is on a decline, and misinformation is spreading rampantly, people are even more divided than ever ideologically

Are mental health problem broadly definitely up, or is it possible that diagnoses are just up?
It doesn't seem implausible that destigmatizing mental health would lead to increased diagnoses even if the base rates were unchanged.

是心理健康问题明显增多了？还是说现在诊断发达了，发现得多了。

kiwidog8
Yeah I think increase of diagnoses is a part of it, but it's hard to tell what our baseline was before hand
There is some information floating around suggesting that social media (but also internet and gaming as a whole) is greatly influencing how our brain develops, as well as building new habits, and some of it is really problematic.
I know for myself, and I see it in my peers, constant social media and "cheap" entertainment is really lowering our attention span and ability to focus on steady and less stimulating activities that are more beneficial to us in the long-run. It is reducing our drive to seek out anything that is not immediately gratifying, no matter how beneficial we know it is to us. With that. a host of other problems can happen like less desire for physical activity, lack of sunlight, poor eating habits, etc. leading to overall worse mental and physical health.
This has just been my experience though. Of course every individual case is different. It wouldn't be right to say strictly that social media and internet are a direct cause for mental health issues, there are lots of factors that contribute to mental health

没错，我觉得诊断发达也是一个原因，但很难找到参照物。
有一种说法，社交媒体(包括互联网和游戏)极大地影响了我们的大脑发育，以及习惯的养成，其中有些习惯确实有问题。
我的亲身感受，包括从同龄人身上看到的——不间断的社交媒体和“廉价”的娱乐活动确实令我们的注意力范围减小了，我们专注于持续、平和的活动的能力降低了，而这些活动对我们长远来说更有利。
同时，社交媒体还让我们对不能立即提供满足感的活动兴趣缺缺，哪怕我们心里知道对我们很有好处。
还有很多其他问题，比如缺乏锻炼的欲望、缺少阳光、不良饮食习惯等，导致心理和身体健康状况整体恶化。

Don't you think some of the things our generation vehemently defend might not also  part of the blame? Ahem porn weed gaming ahem

难道你不认为我们这一代人坚决捍卫的一些东西也该受到谴责吗？比如色片，大麻、游戏等等。

kiwidog8
Yes, we have an issue with overindulgence in general. Internet is still relatively new and the things we do on the internet is new so we are experiencing new issues as a result of that. Weed isn't related to internet but normalization of smoking weed is definitely a problem in some respects, but not everything is so black and white. There are benefits and problems in everything

是的，我们总体上有纵欲过度的问题。互联网是相对较新的事物，我们在互联网上做的事儿也很新鲜，所以我们正面临新问题。
大麻与互联网无关，但吸大麻的普遍化肯定是个问题。但不是所东西都黑白分明，凡事皆有利弊。

Since social media has come, Human contact has never been as low, a significant chunk of the population (Chunk growing with now adults applying no restrictions to their children) do not know how to properly interact with other people and toxicity has both massively increased and is being called out more often than there actually is.

自从社交媒体出现，人与人之间的现实接触从没有这么低过，很大一部分人(而且大量成年人根本不限制孩子接触社交媒体)不知道与他人互动的正确方式。

Social media gave "a voice to the people". But the issue is most people are ignorant and predisposed to say stupid things, so their voices are just stupid messages that get repited with a sense of importance because they are displayed another people's screens.

社交媒体提供了“人民的声音”。但问题是，大多数人都很无知，喜欢说些蠢话，所以他们的“声音”只是愚蠢的信息，只不过他们的信息显示在他人的屏幕上，仿佛就有了种很重要的感觉。

Latvia
That’s probably a smaller part of the problem. Most people are ignorant. All of us are, in the grand scheme. But before social media, most people knew they were ignorant. They didn’t think they knew more than doctors or engineers or historians, etc. They were well aware that they did not. But now, the second an incorrect idea pops into your mind, before you can even have time to think “I don’t actually know anything about this topic,” you are already engulfed in support for the incorrect idea, so you never, ever have to be wrong about anything.

这可能只是问题的一小部分。大多数人确实很无知，放眼世界，我们所有人都是如此。但在社交媒体出现之前，大多数人还有自知之明，他们不会觉得自己比医生、工程师或历史学家等懂得多。
但现在，一个错误想法刚在你脑海出现，你就被“支持”这个错误想法的信息或人给淹没了——甚至你都没时间思考：“实际上我对此一无所知”，所以你永远、永远不会觉得自己错了。

My sister is a school administrator. She says that social media is exacerbating conflicts between students. It could be a physical fight, name calling or whatever. It’s captured on video, posted to Instagram where these kids are constantly reminded of the conflict and eventually seek redress, which ends up recorded and put on Instagram.

我妹妹是学校的行政人员。她说，社交媒体正加剧学生之间的冲突，肢体冲突，谩骂等等。然后这些冲突被拍下来，上传到Instagram上，不断刺激着孩子们，最后寻求报复，结果又被拍下来上传到Instagram上。

That’s so heartbreaking. I always say to my friends that I wouldn’t have survived at school.
We had something years ago called Bebo, I never used it…I was victim of revenge porn and did something (I’ll let you use your imagination)with a boyfriend in the woods. His “friend” was there and decided to take a picture. He then plastered it on Bebo. They entire year of my school saw it. I was bullied. There wasn’t any services to report this, nor was it illegal. It pretty much ruined me and I moved schools. I was lucky I had a chance of a fresh start, kids sometimes are not so lucky.

太让人心碎了。我总是对朋友们说，我在学校活不下去。
几年前有一个叫Bebo的东西，我从来没用过……我是报复色情的受害者，我和一个男朋友进了小树林。他的“朋友”在那里，决定拍张照片。然后把它贴在了Bebo上。整个学校的人都看到了。我被欺负。没有求救渠道，这种行为当时也不违法。这差点毁了我，我换了学校。我很幸运有机会重新开始，但孩子们有时就没这么幸运了。

Honestly Facebook back when it was founded was much different than it is today. I joined around 2008 as well and back then it was literally about being connected with friends. Now it’s just a place for people to air out their drama.

老实说，创立之初的Facebook和现在大不相同。我也是在08年左右加入的，当时基本上就是为了联系朋友。现在它只是个让人们发泄情绪的地方。

I was on Facebook early and Twitter very early, and both were great.
Facebook was people getting back in touch with old friends after many years and people were friendly and nice to each other. Twitter was adults who had something interesting to say and who enjoyed connecting with like minded people with d interests.
Unfortunately, the more popular they got, the more the culture changed and the more toxic they became.
It seemed to me at the time that the cultures and problems were being caused by the idiot adults and the kids who were joining as they became more and more popular. They slowly became something else entirely, turning into the cesspool of egotism, anger and insults that they eventually became.

我很早就上了Facebook和Twitter，当时它们都很棒。
那时的Facebook，人们用它和多年的老朋友重新取得联系，人们对彼此都很友好。推特呢，成年人发表一些有趣的东西，和志同道合的人交流。
不幸的是，它们变得越来越流行后，其文化就越来越变味儿，它们就越来越有害。
在我看来，这是那些涌入的白痴成年人和孩子造成的。他们慢慢免得面目全非，最终变成了自私自利、愤怒和侮辱的大坷垃坑。

icepuc10
Back then there was no advertisement on social media. It was pretty much a way to connect with old friends. Once companies got involved and started to push their agenda is when things started to get nasty.
Imagine if their were no news pages on social media. Only people you could talk to were friends. Things would be a lot better.

那时社交媒体上还没有广告。它是一种和老朋友交流的方式。
一旦公司介入并开始推动他们的利益，事情就开始变糟了。想象一下如果社交媒体上没有新闻。你只能和朋友聊天，情形会好得多。

There used to be lead in gasoline; they thought it would improve engine performance.
Not only did it ruin people's lungs, many believe that it caused an increase in violent crime, because things like muggings almost disappeared after lead was taken out of gas.

以前的汽油中含铅；他们觉得这可以提高发动机性能。它不仅伤害了人们的肺，许多人还认为它导致了暴力犯罪的增加，因为自从汽油不再含铅后，抢劫之类的事儿几乎消失了。

这就是为什么我们需要记住克莱尔·帕特森，他发现了这一切，为了推动汽油和食物容器禁止含铅，与这些行业斗争了几十年(他们尽一切可能诋毁、污蔑他)。

tina_the_fat_llama
Lead allowed for higher octane fuel because it made it more stable. This is why race fuels (110 octane) tend to have lead in it and it's also advertised not for road use.
I think some planes that still use combustion engines require leaded fuel.
Interesting topic related to this, but it's a possibility that the use of leaded fuels has caused some permanent brain damage in individuals that were alive while leaded fuel was widely used.

高辛烷值燃料可以使用铅，因为它让燃料更稳定。这就是为什么赛车燃料(辛烷值110)往往含有铅，而且也明确声明这种燃料不能上路。
我认为一些仍然使用内燃机的飞机需要含铅燃料。
相关话题很有趣，但有一种可能是，使用含铅燃料会对经历过含铅汽油时代的人造成永久性脑损伤。

oldbastardbob
I'd like to clarify something here.
The lead in fuel for internal combustion engines was a lubricant to help decrease exhaust valve recession (wear of the valve face and valve seat interface).
It did have the added advantage of slowing the rate of combustion but that problem still exists with lead free gasoline so other chemicals, themselves just as bad (MTBE for one), have been added to solve that problem. Without these chemicals detonation occurs (premature ignition, don't you hate it when that happens) which will destroy the piston.
Taking the lead from the fuel meant the exhaust valves and seats had to be made of superalloy materials like Inconel or martensitic stainless steels that would maintain hardness while glowing red at 1500 degrees f.

我想做一些澄清。
内燃机燃料中的铅是一种润滑剂，有助于减少排气门老化(阀门表面和阀座接口的磨损)。
它确实还有减缓燃烧速度的优点，但问题在于，就算不加铅，也要加其他化学物质 (MTBE（甲基叔丁基醚）就是其中之一)。如果没有这些化学物质，就会发生爆炸(过早点火，你不讨厌这种情况吗？)，这会破坏活塞。
去除燃料中的铅，意味着排气门和基座必须由铬镍铁合金或马氏体不锈钢这样的耐超高温耐腐蚀合金材料制成，即便在1500华氏度下都变红了还能坚固如初。

If you ran unleaded fuel in older engines they develop valve problems, either rapid wear or burned exhaust valves.
I worked for the worlds largest engine valve manufacturer in the 1980's. It was already known that diesel engines were subject to exhaust valve wear so they used superalloy exhaust valves already. Same goes for air cooled gasoline aircraft engines.
So we started making two and three piece exhaust valves with heads made from those same alloys as an answer to the problem.
The significant amount of metallurgical and valve train dynamics research put into this problem led to development of new materials and alloys resulting in the much more efficient internal combustion engines today.
I in no way mean to be pedantic, but thought somebody should clear up the role of lead in gasoline.

如果你在旧发动机中用无铅燃料，就会出现气门问题，要么是快速磨损，要么是排气门烧毁。
20世纪80年代，我为世界上最大的发动机气门制造商工作。由于柴油机排气门磨损严重，所以已经用上了耐高温合金排气门。空气冷却汽油飞机引擎也是如此。
所以我们开始用同样的合金制造两个或三个排气门来解决这个问题。
对冶金和气门结构动力学投入了大量，带来了新材料和合金的发展，带来了我们今天更高效的内燃机。

DuPont was great at that.
They have a museum up in the brandywine valley where they used to make gunpowder. It was supposed to just be for the unx, but the duponts couldn’t help themselves and sold to the confederacy too.
It actually caused part of the company to break off and become a different entity.
Funnily enough it’s why DuPont has such great safety measures these days. They “blew people across the river” so much in these big ass explosion when they made the gunpowder that it was actually profitable to be strict about safety.

Pull ups!
They are definitely convenient and have their uses. I seriously think pull ups have caused children to potty train at a much later age. We used to have kids potty trained by 2-3 and now normal for them to be closer to 4. My 4 year old is in PreK and about half the class is in pull ups several still in diapers. She is 1 of 2 that doesn't need any potty help.
Also there was post on the teaching and early childhood education subreddit about it. We have kids in kindergarten and first grade showing up in pull ups.

拉拉裤！（保洁公司的一种纸尿裤）
它们确实很方便，有其用途。
但我真的认为，拉拉裤导致孩子们在很晚的年龄才学习上厕所。
过去，孩子2-3岁时候我们就教他们上厕所了，现在正常情况下都快到4岁了。我4岁的孩子上学时，班上差不多一半的人还穿着拉拉裤，有几个还穿着尿布。只有我女儿和另一个孩子2个人上厕所不需要别人帮助。

I thought you meant the physical exercise pull ups and was wondering how the hell that related to potty training a child. Then I remembered the diaper underwater hybrid existed.

作为一个在痴呆患者养老院工作的人，成人拉拉裤是绝妙的发明，穿上看着像短裤，不会尴尬，女士、男士们可以随心所欲自行如厕。我只在有需要的时候才帮把手。相比“经典版”的屁垫，拉拉裤带来了尊严和独立。

Teachers aren't responsible for changing diapers. I could just picture the kids going home in soiled pull-ups from that morning.
I don't think it's pull-ups causing kids to not learn how to potty train, I think it's parents using them as a band-aid and not actually training their kids.

老师们没有帮忙换尿布的责任。我脑海中忍不住出现孩子们晚上回家，穿着已经穿了一整天的、脏兮兮的拉拉裤的画面。
我不觉得是拉拉裤让孩子们不学习怎么如厕，我认为是懒惰的父母把拉拉裤当创可贴用，而不去教他们的孩子。

Agreed 100%.
Parenting is really hard. Imo the parents of this current generation are over-informed and over cautious. I have really grown to respect how much my parents worked to create consequences and boundaries for me. I have a 10yo sister, being raised by the same parents, that isn't getting any of that and she's honestly a nightmare to be around.
She wasn't potty trained until 1st grade, and was only motivated because her peers made her so embarrassed over it.

百分百同意，养孩子真的很难。
在我看来，这一代人的父母看太多、想太多。我有个10岁大的妹妹，她真的是个噩梦。她直到一年级才接受如厕训练，她之所以有动力去学，纯粹只是因为她的同龄人让她感到很尴尬。
