作业写完了。你拿起手机：“就看一条，看完就去洗澡。”Homework’s done. You pick up your phone: “Just one video, then I’ll shower.”从图书馆回到宿舍，论文后天交。你拿起手机：“就看一条，看完就写。”Back in your dorm from the library. The paper is due in two days. You pick up your phone: “Just one video, then I’ll write.”
先别急着怪自己。下面这些话，看看有几句是你。Don’t blame yourself just yet. See how many of these sound like you.
你中了几条？How many of these are you?
这不是懒。是在躲难受。It isn’t laziness. You’re dodging a bad feeling.
为什么偏偏是该写作业的时候，最想拿手机？试试这个：Why is it exactly when you should be doing homework that you most want your phone? Try this:为什么偏偏是 DDL 快到的时候，最想拿手机？试试这个：Why is it exactly when a deadline is closing in that you most want your phone? Try this:
① 现在你最不想碰的是哪件事？① What’s the one thing you’re avoiding right now?

里面的原因说完了。外面还有一个：屏幕另一边的推荐系统。That’s the reason on the inside. There’s another on the outside: the recommendation system on the other side of the screen.
推荐信号实验The signal lab
推荐系统会根据你的互动、内容本身和使用环境，猜下一条你更可能想看什么。关注、点赞、看了多少、用什么语言、人在哪里，这些信号都可能参与。但没有哪个平台公开过一份外人能核实的实时“权重表”。 来源Source
A recommendation system uses your interactions, the content itself and your context to guess what you are more likely to watch next. Follows, likes, how much you watched, your language and location can all play a part. But no platform has published a live “weight table” that outsiders can check. 来源Source
① 给它点信号（点满三次，盖第一枚章）① Send it a signal (three moves earn your first stamp)
② 试一个能撤回的小策略② Try a move you can undo

- 你看到一屏You see a screen
- 它记下你的反应It logs how you react
- 它重新猜你喜欢什么It re-guesses what you like
- 下一屏更像你The next screen fits you more
它给你的下一屏Your next screen
你喜欢的会被加强，但系统通常也会留一点位置给新东西，试探你会不会喜欢。这是简化演示：不代表 TikTok、抖音或其他平台用的是同一套公式，不同产品、地区和时间的系统都会变。What you like gets reinforced, but the system usually keeps a little room for new things to test whether you’ll like them. This is a simplified demo: it is not the formula used by TikTok, Douyin or any other platform, and real systems differ by product, region and time. 来源Source

22:30你抬头一看，四十分钟没了。这时手机震了一下：班级群年级大群 99+。它推来的、别人转来的，都是真的吗？You look up. Forty minutes, gone. Then your phone buzzes: 99+ in the class chatyear group chat. What the feed sends you, what friends forward: is it all real?
