The remark "you might want to reconsider whether your powers of self-diagnosis" is not using "consider" in the same sense that I used it in the comment you're replying to. You are not really asking me to consider anything. You are mirroring the word choice, but the thrust of your comment is an argument that my comment is probably not true, and that it is almost self-invalidating.

Perversely, you are doing exactly the thing that the statement "Consider this: I have a high emotional IQ" is exhorting you not to do, which is to tunnel vision your way to one of the possible outcomes--the one where it isn't true--and then try to reflexively use it to justify the starting position that leads to that outcome. You are failing to consider the counterfactual.
