>People who think judging performance is hard have a broken development methodology or no technical chops.
And this is exactly why I asked the question. Here you have judged me, since I said judging performance was hard, on both my development methodology and technical chops. Yet you know nothing about me at all.
The problem of evaluation is an important one, and one I'm always interested in reading more on. Unfortunately the strategy of taking one's self as a gold standard isn't exactly what I was looking for. It does seem obvious that being an expert in your domain is a necessary trait to be able to evaluate others, but it's not at all obvious that it is a sufficient trait.
The idea of multi-source feedback seems intuitively good, despite the conflicting research on it. That more input will expose biases or inaccuracies is a decent hypothesis. On the other hand, judgment from a single person seems highly error prone. Whatever faults that one person has will never be exposed and reviews seem almost guaranteed to have bias.
In the end, I'm left with no idea why you so quickly discard the reports of your peers.
