The bias point is well made. I don't remember the quote exactly, but i think it's something like "...when all you know are hammers, everything looks like a nail...". Though I think his point is that you have to at least be able to form models about the problems you tackle and stick to those models. I feel like you need some commitment or vision to be able to move on. Development tends to have two phases, exploration and exploitation. Balancing the two is a real problem. If you exploit too soon you may miss a much better solution, but if you do too much exploring you may just be wasting time. Balancing the two contributes to writing good code it seems.
