If someone had bad education credentials (bad school, dropout, etc) but they put a high SAT score on a resume that would be a pretty concise way of communicating "it wasn't because I'm dumb"

It’s possible that the received signal would be “I test well, but I struggle to complete a structured, long-term course of action”, which probably isn’t that beneficial.

I'd still prefer that to "I both test poorly and struggle to complete a structured, long-term course of action" which is just as likely an interpretation if you left it off.

At the end of the day, anything could be bad if viewed with sufficient cynicism, and you can't control how others will interpret what you present, you can only control the information which is presented.
