> seen enough things to know what the right solution is in many cases

When dealing with uncertainty (nearly always) it's generally easier to identify and rule out what 'wrong' solutions are. There are often multiple obviously 'wrong' options (no, we should not keep a user's password in plaintext, even if the goal is to make it easy to recover a lost password), but picking a 'right' one... from a whittled down list, it may often come down to familiarity or convention rather than an arbitrary "this is the only 100% correct solution".
