Generate：Raise a question
Test：
Novelty test: Figure out to what extent we know how to answer the question
There’s already an answer to it: Is the answer good enough?
Yes: not interesting, but can you make the question more challenging?
No: your research problem is how to get a better answer to the raised question
No obvious answer: you’ve got an interesting problem to work on
Tractability test: Figure out whether the raised question can be answered
I can see a way to answer it or potentially answer it: you’ve got a solvable problem
I can’t easily see a way to answer it: Is it because the question is too hard or you’ve not worked hard enough? Try to reframe the problem to make it easier
Evaluation test: Can you obtain a data set and define measures to test solutions/answers?
Yes: you’ve got a clearly defined problem to work on
No: can you think of anyway to indirectly test the solutions/answers? Can you reframe the problem to fit the data?
Every time you reframe a problem, try to do all the three tests again.

主要观点：（1）问题是科学研究的真正起点。
（2）问题实质：矛盾、疑惑、怀疑。
（3）问题类型：
a.某个理论体系内部的逻辑矛盾
b.不同理论体系之间的矛盾，如耗散结构理论的出现
c.理论结构不符合简单性与普遍性要求
d.现有理论与经验事实之间的矛盾
e.对经验事实未能作出统一的理论说明
f.理论应用与现有技术条件的矛盾
