From Wikipedia:
Twyman’s law states that “Any figure that looks interesting or different is usually wrong”
A bit different from that oft-quoted line attributed to Isaac Asimov:
The most exciting phrase in science is not ‘Eureka!’ but ‘that’s funny’
But Twyman’s law is much truer in my experience. Surprising results are usually a signal that something is screwy with my data, my assumptions, or my pipeline.
