Well, that snake may be an exception that's not acknowledged by the keeper as one. He may take that one case into consideration and completely overlook the 99 others that lived a significantly shorter life under the same conditions, compared to the other group.

That's something that people do frequently. People take one or a few cases that seem to confirm what they expect and completely ignore or downplay the cases that either don't confirm the theory, or outright disprove it. Examples would be to allow cases of mistreatment, or differences in the skills of the keepers in a comparison between two housing solutions.

Unless the risk of confirmation bias has been eliminated, nothing has really been proven.

People also suck at noticing statistically significant differences.
