    Before playing the game, the participants sniffed either female tears or a saline solution

    Why would they not include male tears in the test?

      If male tears were the only control, then they run the risk of not finding any result. If you have 3 groups, you need a substantially larger sample size because you are running a less powerful statistical test.

      Easier to start with the test that’s most likely to work, and narrow it down from there if you succeed

        Having men sniff three different samples would still allow for saline as a control and wouldn’t really make the data set that much more complicated.

            Just college lab courses, but come on, it’s pretty basic. The experiment merely tests a single variable by changing it while keeping everything else the same. There could have been dozens of different samples that men sniffed and it wouldn’t really make the data complicated.

            It would increase the length of the test, though, so dozens of samples would have been cumbersome. But just two? Literally just “see how the test group responds to sample 1, sample 2, and the control sample”? That’s not complicated science. You probably did that in highschool lol

              Testing multiple hypotheses this way still requires additional sample size because there is an increased error likelihood. From a statistical point of view, the most efficient test may be to stick to one variable like this.

              I’m guessing they had to stay within their funding/budget and didn’t want to reduce the sample size to increase the number of variables tested. MRIs are expensive

                they should just be getting time on the machine although maybe also tech time. either way doing multiple with a single individual is easier than more individuals.

                  But that makes it more complex because you have to start worrying about the order they’re done in because it might be different emotions playing your first or third game plus the effect might linger, take time to show, etc.

                  Far better to answer one simple question and prove there is an effect then follow up tests can look at finding the bounds to that and starting to narrow in on identifying mechanics.

                    its been done with other things. its an mri so regardless of order the simuli should light up the brain regions. either it does it or it does not.

            I have experience and yes, it would not make it much more complicated. two types of controls are actually common although using male tears would not be a control. but like 5 research targets and 2 controls would not be beyond belief.

      They said they had a hard time finding men who would cry.

      They also didn’t test women sniffing women’s tears, or men sniffing men or women sniffing men, or animal tears.

      They left a lot of variables out of this one.

      I thought the same thing, so I checked the real paper and they do end up explaining their reasoning.

      As for social interactions among humans, future research will explore whether the new study’s findings apply to women. “When we looked for volunteers who could donate tears, we found mostly women, because for them it’s much more socially acceptable to cry,” Agron says.

      I’m interested if the results are same for male tears and also if they’re the same for women who smell either gender’s tears.

      I feel like they should also have experimental groups of children and the elderly, to see whether age also has an effect on hormonal responses.

      I suppose that applies both in regards to tears from and how tears affect. Hmm, I can see this getting rather complicated and extensive.

        I find this is my answer to most things honestly.

      Seems there was a study that concluded female tears raise testosterone of men. I thus think it’s kinda understandable they did it in this way. But, yeah, not really convincing.

      Because they sought to justify male aggression toward a non-subservient target.
