The Big 5 test was suspect on some things. Am I really lowest quartile conscientiousness and agreeableness? I defy the data.

I think the test is noisy on agreeableness. Six months ago I got 76%, and a couple of days ago I got 17%. The same person answering the same questions with the same friend being used as a comparison.

The other four (Open 95% Conscientious 41% Extravert 91% and Neurotic 4%) were as stable as you'd expect, and reflect my self image.

I have no idea whether I'm actually agreeable or not. I certainly can be, and I can also be spectacularly nasty. And I guess what you think of me would probably depend on which face I've mostly chosen to show around you. (it usually is a conscious choice).

I wonder if the test score is being influenced by which memories are most salient when I take the test.
