That's not really true at all. You just think that because you never hear about it. Stare decisis still applies at a trial level, but its scope is obviously much narrower. Moreover, most things really aren't that novel. Most importantly, its quite hard to research on this level and usually pointless because theres usually a higher level case anyway.

It is just persuasive precedent so any other court, or even the same court when dealing with case involving different parties, can ignore it.
