A good measurement culture where numbers don’t replace common sense
Human intuition is based on raw data - photons, pressure waves and so on. Extracting meaning from this raw data is complex. Maybe, one day a machine will be able to look at various performance metrics (time to last byte, load times, commits per day, etc) and give us a concrete plan of action. However, we don’t have that today so should probably learn to trust the associative cortices since it is the best machine that we currently have.
