In college we used to joke that animal behavior should be called animal misbehavior. We literally had one member of our lab group that could work with the mice and get sensible results. Neither of the guys could get any data that made sense, one of the women owned a cat and none of the results she had made any sense, and the fourth person (a woman) had no problem.
I'm not sure if anybody suspected that rats reacted differently to how men and women smell, but only women were allowed to work as rodent caretakers or be in the rodent room at my school. Our professor showed the guys the room once, but we weren't allowed to talk, since she thought it was men's voices that set the rodents on edge.
In case anybody is wondering what our experiment was, we were measuring whether caffeine affected the VO2 of mice. Their oxygen consumption pegged anytime any of the guys handled them.
- anitil 9y agoWere rats as sensitive as mice?
- chiefalchemist 9y agoFwiw I have been assured that Big Pharma will swap out a set of mice (or whatever the test species is) as a way to find the results they're looking for. This was told to me by someone who does research for Big Pharma. Someone who I have no reason not to trust.
- zaarn 9y agoBut how can we trust you to tell the truth about this?
- chiefalchemist 9y agoMy personal motto is: Don't be evil. Does that help? ;)
- ComputerGuru 9y agoI just wanted to add another anecdote (because the plural of anecdote is, as we all know, data) that your profess isn’t the only one. I’ve heard a few similar stories about guys not being allowed to enter the rodent living chambers besides an initial, introductory visit in the past.
- calinet6 9y agoThis is really interesting. Clearly they're trying to control for sensitive variables that make little sense even to them, and yet they're still using rodents as subjects and publishing studies likely without mention of these oddities. Not saying everyone is doing it wrong, but wow.
- fhood 9y agoYou have to allow for some level of pragmatism. They found a method that seems to provide better data without actively biasing their results. Rodents make convenient test subjects, and no scientist wants (or more likely it doesn't even occur to them) to include an unproven methodology in their published work.
- kbutler 9y agoAre they publishing "make sure only [female name] handles the mice"? Or do they just publish, "X caused effect Y"? Frankly, identifying why it requires a female, or female non-cat owner sounds like it may be more interesting than whatever other result they are working on...
- Declanomous 9y agoIf results were thrown out because of a confounding factor then it would hopefully be mentioned in the paper. I've had a similar thought about these little insights. There are literally thousands of times more biology undergrads than there are people doing biology research. Biological experiments are notoriously difficult to conduct. There are so many confounding variables, data is hard to collect, etc, that experiments bomb as often as they succeed. A lot of these experiments are extremely well supported, so you might actually be able to discover something novel if you were able to track the failures. Anyways, I don't do anything with biology anymore, but I strongly believe that biology is a field where citizen scientists could make a meaningful impact.
- freeflight 9y agoI wonder how practical it would be to automate all the rodent handling/experimenting? Because that seems like it'd be the only way to properly remove such unaccountable influences, like people smelling of cat/giving off different smells and thus influencing the reactions of the animals. Couldn't it also be possible that rodents reacting like that is the result of established practices? I.e.: Rodents get only handled by females, rodents adapt to that female smell while reacting differently to the male smell due to its unfamiliarity?
- SeanDav 9y agoEven automation would not solve this issue. If these results are scent related, then it is quite possible that different automation methods would produce different scents, or even the same method, in a different environment / location. This is a fascinating issue.
- ensignavenger 9y agoBut you could at least use the same automation methods across different study groups within the same study, eliminating potential confounding variables between your groups.
- otakucode 9y agoThen you would have to deal with the effect of subjecting the mice to such a degree of control, precision of action, predictability of environment, and other factors. As was found with the 'Rat Park' experiments in the 70s, experiments on rats in cages are not informative about the behavior of rats not in cages. It is tremendously difficult to study systems as complex as living animals, and we ignore "unimportant" factors at our peril. How different would our society be if the Rat Park experiments, which showed that rats addicted to cocaine will naturally ween themselves off of the drug when provided with a stimulating social environment, was reported on first instead of the one we heard about instead that claimed cocaine was so addictive that a rat which takes a dose becomes inescapably addicted and will dose themselves with it until they die? (Which they will.... if they are locked in a cage and the alternative is just living in a miserable cage.)
- jrcii 9y agoWe should see what would happen to their oxygen consumption if one of the guys identified as a female, because that means they're female, right? That's what NPR and the San Francisco liberals who run this website told me to think.
- autokad 9y agointeresting stuff, hope this was all documented in the papers derived from those experiments
- Declanomous 9y agoI didn't go to a research University, and I'm fairly sure none of the staff used mice as a model organism. I think they were merely used in student experiments. Now some of those students may have published work as part of their senior capstone, however it's pretty unlikely. You need a lot of knowledge to get to the point where you can publish something meaningful in biology. If you were to publish a work as an undergrad, you are probably working on a professor's project or with a less complicated topic.
