Am I the only one who thinks the Viking sunstone theory is overblown?

Back when I first got into archaeology in 2018, I was all in on the idea that Vikings used sunstones made of calcite to navigate on cloudy days. I even wrote a school paper about it. But after reading a study from the University of Bergen last spring that tested actual calcite crystals in real sea conditions, the results were pretty weak. The crystals only worked right maybe 1 in 10 times. Has anyone else seen that study and changed their mind?

Kept reading about how these crystals were supposed to be this brilliant navigation tool and then actual tests showed they barely worked at all. Kinda reminds me of that whole "coffee enemas cure everything" trend that science later debunked. People love a good story about ancient wisdom being this secret superpower. It makes us feel clever for rediscovering it. But most of the time the reality is just boring and the tools were probably just okay at best. The Vikings were tough and lucky, not magic.

That part about "people love a good story" really hit me. I saw some documentary a while back about a guy who actually tried to recreate the sunstone using modern calcite and tested it on a boat. He said it worked maybe one in four tries, and only when the sky was perfectly clear. The whole thing felt like a letdown. But I guess that's the thing, we want the Vikings to have had some secret tech because sailing those routes in open boats seems insane. They probably just read clouds, birds, and waves way better than we give them credit for.
