Field Notes · Compensation
The market rate can’t price the person in front of you.
Leaders reach for a salary survey because it feels responsible. Underneath the number is a stack of problems: bad samples, mismatched jobs, stale data, and statistics that hide more than they show. Here are eighty of them, sorted into ten failure modes. No single line is the argument. The pile is.
80 reasons salary survey data is unreliable, grouped into 10 failure modes. Each reason lists a one-line explanation.
Why “the market rate” can’t be trusted

The data answers the wrong question. A survey tells you what people are being paid. Hiring asks what it will take to attract, close, and keep the right person now. That answer never lived in the spreadsheet. It lives in your mission and your P&L.
