i didn’t make clear but in the article the writer says she had no idea how to do the requested task. she knew she didn’t know how to do it, but she didn’t know she’d be able to figure out how to do it, which in a way is like not knowing you don’t know how to do something. But I suppose the costs of showing “weakness” exceed the possible perception of unfoidence if you are truthful, so the rational direction is to live ina general state of denial of your limits, always proclaim ability and proceed with throttle wfo.
