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.

You are being silly. Self sabotage is not what we are talking about here and not relevant. In fact, if your definition of a 'perfect score' was actually what the test was talking about then you would be self sabotaging. See my previous support of the test itself and advocacy of a more nuanced evaluation system than integer difference minimization.

No, sincerity is the opposite of bullshit.

"Sincerity is bullshit." is actually a direct quote a from On Bullshit. Those people here that use the term bullshit tend to mean it in the same sense described in that philosophical treatise.

I never reward people, even myself, for self deception.
