There needs to be a name for the phenomenon where people start executing without instrumenting or thinking, and then turn out to do worse in the long run compared to teams who take the time, up front, to instrument properly.
Actually the more general phenomenon is "you know doing thing X upfront is good, but it doesn't feel like you're doing anything while you're doing X, so you don't do it, and then you do worse overall."
I do it on my first pass of a text to mark areas I think are important or I need to investigate. On my second pass I review only annotations.
Good article on this:
