SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“He ships in a day what takes me a week”
YOUR RECORDED RESPONSE
“Different tickets, different codebases, different luck. The benchmark is invalid.”
ONE PRIVATE MOVE
Open a note and list three concrete differences between your last hard ticket and one fast-shipped task you noticed today: codebase age, unknowns, and dependencies. Keep it private and stop at three.

McConnell traced the '10x programmer' claim to the 1968 Sackman/Erikson/Grant study of 12 programmers and documented how the ratio — originally about debugging time on a single task — was repeatedly cited, decontextualized, and amplified over five decades into a broad claim about general developer productivity.
