I think you should have posted just the links to the questions and the instructions on which link to follow without explaining what the experiment is about.
That would be certainly a reasonable way to do it, however I suppose that the LW audience is well informed about the biases and able to guess what it is all about even without being explicitly told. Meanwhile I wanted to provide some explanation why I am doing this, and to publish the tested hypothesis in advance (as a measure of honesty).
The effect seems robust enough to survive when people know that they are being tested for it.
