That just means you lied to the test, which made it useless in determining your capacity to estimate certainty levels.
No, what it means is that your description of the "perfect" score is wrong. Emphasis on "your" because the test itself makes no such declaration, leaving scope for a nuanced interpretation (as others have provided here).
Try for an honest attempt next time, then it'll help you better.
It is not relevant (see above) but this too may be mistaken. Tests that are foiled by 'lying to them' are bad tests. Making a habit of engaging with them is detrimental to rational thinking. They measure and encourage the development of the ability to deceive oneself - a bias that comes naturally to humans. "Sincerity" is bullshit.
Tests that are foiled by 'lying to them' are bad tests.
Really? What test can you imagine that checks your ability at anything which can't be foiled by intentionally attempting to foil it?
A test that measures your speed at running can be foiled if you don't run as best as you can. A test that measures your ability to stand still can be foiled if you intentionally move. And a test that measures your intelligence can be foiled if you purposefully give it stupid answers. Which is what you did.
Perhaps you mean that this would be a bad test for someone to use...
So you think its important to be able to estimate how well you are estimating something? Here is a fun test that has been given to plenty of other people.
I highly recommend you take the test before reading any more.

The discussion of this test at the blog it is quoted in is quite interesting, but I recommend you read it after taking the test. Similarly, one might anticipate there will be interesting discussion here on the test and whether it means what we want it to mean and so on.
My great apologies if this has been posted before. I did my bast with google trying to find any trace of this test, but if this has already been done, please let me know and ideally, let me know how I can remove my own duplicate post.
PS: The Southern California meetup 19 Dec 2010 was fantastic, thanks so much JenniferRM for setting it up. This post on my part is an indirect result of what we discussed and a fun game we played while we were there.
