Article: “A Scientist’s Gender Biases Mouse Research”
“Duhaime-Ross reports on a new study, which found that mice are scared of men. When a male researcher works with a mouse, the mouse’s body courses with stress hormones. This doesn’t happen when a woman scientist is doing the work. The difference in how mice respond to male and female researchers could potentially skew everything from behavioral studies to cell research.” https://www.smithsonianmag.com/smart-news/scientists-gender-biases-mouse-research-180951240/
The gender-related bias found in the above research shows how broadly one form of bias can affect research results. The behavior of the mice towards male researchers is a form of bias. Most RLEs that address bias probably focus on human bias but animals also have their own biases.
One benefit of the bias in this case is that it can be studied and it can be used to understand how gender affects interaction between different species.
