Not to just reframe AnimalMuppet's point, but which of these two things is more likely?

1) Your couple hours of research has uncovered something blatantly obvious that was somehow missed by the other party.

2) Your couple hours of research hasn't shown you some edge case or something that is common knowledge once you've been in the field for 2+ decades.

I'm not saying #1 never happens, only that #2 is much more likely. It's a horses vs. zebras argument.

3) The other party has a lot of stuff on his/her plate and does not get the luxury to spend hours of research/thought on architectural details.
