> DK doesn't mean no correlation, it means inverse correlation Both are wrong. DK effect describes a weak positive correlation, but weaker than we intuitively expect. The top quartile still estimates their ability better than the bottom - positive correlation. But this is still below their actual ability. The bottom quartile correctly predicts they score worse than the top, but they overestimate their own ability ie they underestimate how much better the top quartile actually performs.
