The answer here is pretty simple: we don't release it because we don't track it. Microsoft takes a pretty strong stance on privacy and unlike in an experiment, where people give informed consent to having their results tracked and used, people who come to BingItOn.com are not agreeing to participate in research; they're coming for a fun challenge. It isn't conducted in a controlled environment, people are free to try and game it one way or another, and it has Bing branding all over it.
So we simply don't track their results, because the tracking itself would be incredibly unethical. And we aren't basing the claim on the results of a wildly uncontrolled website, because that would also be incredibly unethical (and entirely unscientific).
Ayres' final issue is the fact that the Bing It On site suggests queries you can use to take the challenge. He contends that these queries inappropriately bias visitors towards queries that are likely to result in Bing favorability.
First, I think it is important to note: I have no idea if he is right. Because as noted in the previous answer, we don't track the results from the Bing It On challenge. So I have no idea if people are more likely to select Bing when they use the suggested queries or not.
Have you tried the Bing It On challenge? You run five different searches, with the results divided into Bing and Google. You can choose the results on the right, or on the left, or "I can't decide, it's a draw." If you can't decide, maybe you should DuckDuckGo?
