Should research animals get names?

You might not want to get too attached...

You may have heard of Koko the gorilla or Alex the parrot, but what about Pia, Splinter, Oprah, and Persimmon the rats? Or Nixon the octopus? Or breeder pairs of mice named Tom and Katie or Brad and Angelina? It's not only the animals with good communication skills and long-term relationships with human researchers that get names. As Michael Erard explains in Science, "for many researchers naming is a practice whose time has come."

It hasn't always been that way. In the past, naming was frowned upon because it had the potential to introduce bias. A name might make a researcher ascribe personality traits to an animal on the basis of connotations carried by the name. It also introduced a personal connection to the animal that researchers strove to avoid. In a 1980s study of lab practices, researchers said that "they didn't name because they dealt with so many animals and were interested in them as sources of enzymes or data points, not as individuals."

But it turns out that naming can lead to better science. One lab that used names for monkeys was led to start looking at individual differences between them which "led to the discovery of the genetics and epigenetics of personality in monkeys." On a more general level,

Naming improves animals' lives, argues Brenda McCowan, a scientist at the California National Primate Research Center at the University of California, Davis, who manages the behavioral enrichment program for 5000 rhesus and titi monkeys. "Naming helps create positive human-animal interaction, which is better for the welfare of those animals," she says. Buckmaster adds that naming has become more accepted because "people realized the scientific value of the stress-free animal. … We have to make sure these are really happy animals, or none of the information that we get from them will be valid."
