Definitely yes! Type 2 will get a result out faster, but they’re less likely to pick up on complicated patterns that have emerged within the system, and may not reach a point where they understand all of the parts and how they combine. Type 1 will definitely take longer at first, but given a few months in your codebase, they’ll be able to make more effective trade-offs and understand the system better as a whole. Talking generally of course, there are probably some type-2’s that will still find time to prod around, and some type-1’s that will never get faster… but I think someone who doesn’t just assume that their guess about how a system works is correct, will be more likely to produce quality code in the long term.
