As for hiding the instructions, I don't see a strong reason.

If the coin flip puts me in group II, does not my inadvertently seeing the question intended for group I (e.g., "Is the population of the Central African Republic lower or greater than 20 million?") de facto reassign me to group I? In other words, after I had been exposed to the anchor (20 million) would not my continued participation in the control group have undermined the purpose of the control group?

ADDED.

I suppose priming is a strong enough effect to persist even if people know they are being tested for it.

I tend to agree, but that's not it.

Agreed. It would have been better to always answer the group-II question first, whichever one you were assigned to. (That is, switch the part 1 group II question with the part 2 group I question.)

I have misunderstood you and thought you suggest that I hide parts of the original post.

I have expected that people follow on the links in the bottom of the post. If you click on the group II question link, you don't see the group I question. Of course, if you scroll down, you will see it, but therefore I have warned against reading the comments.
