Lampshading

Isolated situations

Confessing ignorance works at both the senior and junior stages of careers. However, it also works in isolated situations, like, when you caveat what you don’t know while learning in public.

Given my casual interest in creative writing, I often compare this technique with lampshading. To quote from TV Tropes:

“Lampshade hanging (or, more informally, lampshading) is the writers’ trick of dealing with any element of the story that threatens the audience’s willing Suspension of disbelief, whether a very implausible plot development or particularly blatant use of a trope, by calling attention to it and simply moving on.”

Call out your own weakness

Applied to real life: You call out your own weakness so that others can’t.
