Karl Popper used to begin his lecture course on the philosophy of science by asking the students simply to ‘observe’. Then he would wait in silence for one of them to ask what they were supposed to observe. [...] So he would explain to them that scientific observation is impossible without pre-existing knowledge about what to look at, what to look for, how to look, and how to interpret what one sees. And he would explain that, therefore, theory has to come first. It has to be conjectured, not derived.
Did Karl Popper populate his class with particularly unimaginative students ? If someone asked me to “observe”, I’d fill an entire notebook with observations in less than an hour—and that’s even without getting up from my chair.
I have never tried it myself in a structured setting, such as a classroom; but I do sometimes notice things, and then ask myself, “What is going on here ? Why does this thing behave in the way that it does ?”. Sometimes I think about it for a while, figure out what sounds like a good answer, then go on with my day. Sometimes I shrug and forget about it. Sometimes—very rarely—I’m interested enough to launch a more thorough investigation. I imagine that if I set myself an actual goal to “observe” stuff, I’d notice a lot more stuff, and spend much more time on investigating it.
You say that, in such a situation, you could end up “feeling tricked”, but this assumes that the teacher who told you to “observe” is being dishonest: he’s not interested in your observations, he’s just interested in pushing his favorite philosophy onto you. This may or may not be the case with Karl Popper, but observations are valuable (and, IMO, fun) regardless.

And, while you were writing, someone would provide the wanted answer ;)
I’m pretty sure I had this very exercise in a creative-writing class somewhere in school.
That’s an interesting prediction. Have you tried it? Can you predict what you’d do after filling the notebook?
In my imagination, I’d probably wind up in one of two states:
Feeling tricked and asking myself “What was the point of that?”
Feeling accomplished and waiting for the next instruction.

Hmm, this point seems more Kuhnian than Popperian. Maybe Deutsch got the two confused.
Another view.
