Ask About Behavior, Not Intention
People can't predict what they'll do next, but they remember what they did last week. So only ask about the past, never the future.
- 访谈时对方一直点头，做出来他不用
- 问卷结果很好看，转化率对不上
- 问完一圈，笔记里全是形容词，没有一件具体的事
It's not users being evasive. When answering a hypothetical, people picture an idealized version of themselves — one with plenty of time, no inertia, and an eagerness to learn. The real person will go back to the familiar old method next week.
And another layer: the person you're asking wants to make you feel good. You took the time to ask, so they're embarrassed to say it's useless. Asking about intention is basically inviting a polite answer.
How to Rephrase
The rule is simple: replace every "would you / do you want to / do you need" with "last time / at the time / how did you."
| 别问 | 改成 |
|---|---|
| 这个功能你会用吗 | 上次遇到这个情况是什么时候，你当时怎么处理的 |
| 你愿意为它付费吗 | 你现在在类似的事情上花钱了吗，花了多少 |
| 你觉得这个设计怎么样 | 你现在试着完成这件事，我不说话，你边做边讲 |
| 你多久用一次 | 最近一次是什么时候？上一次呢？ |
| 你希望增加什么功能 | 最近哪一次让你觉得特别麻烦，麻烦在哪一步 |
