Hasn't been my experience. People who overthink will always overthink. People who play safe and love to discuss things until the sun comes up, will do just that. People who want to be hands on, break things first and then try it again with new information will do exactly that.

Whenever I see people overcomplicate things, the idea usually comes from a senior and then passed down to the chain of loyal followers. We can have a debate on whether that is a 'true senior', but the books sold, praised by the majority of the dev crowd and then recommended by said seniors don't lie. 5+ years or 40+ years, there have been those going for 'crazy new libraries, patterns and ideas', even bold enough to claim things that no study has been able to back up so far.

And god forbid sometimes a mid-level does figure out something can be done in a better way and the seniors ignore it while stuck in their old ways.
