Are experimental results more reliable than theoretical predictions?

In our research group, there's often a tension when theory and experiment disagree. The experimentalists claim the "ground truth" of data, while theorists argue for the consistency of elegant mathematics. I'm trying to understand the philosophical and practical hierarchy of evidence.

I would caution against a simple hierarchy. In practice, they are a symbiotic pair. An experimental result is only reliable within its error bars and interpretation framework, which itself is theory-laden. Conversely, a theoretical prediction is untested speculation until confronted with data. I have seen beautiful theories fall to a single, robust experiment, and I've also seen experiments misinterpreted due to flawed theoretical assumptions. True reliability emerges from the persistent, iterative dialogue between the two.
