I am not presuming he is a poor performer. I am saying that the quality of his performance is open to question, and I would like to evaluate it for myself. It could be good, and I would not be surprised, as most people hired at Google are pretty sharp. It could also be bad and I wouldn't be surprised, for the reasons mentioned.

Oh, do you have copies of those? I would like to see them, too thanks. Otherwise, you don't have much in the way of evidence that those exist. You have a proven liar about performance making claims about performance. He could be correct in this case, or he could be lying again.

Have you ever been part of a performance review process? Even the best-designed ones are imperfect and political. Sometimes not-very-good people get promoted. Sometimes very good people don't. I have heard a number of stories from Google pals of people energetically trying to manipulate the process.
When it's my job to read performance reviews and promotion packets, I take them with a grain of salt. I look at work output and actually talk with people. Which is all I'm saying I'd like to do here. Maybe Damore really is competent. Maybe he isn't. I'd like to see for myself.
