I wonder what the results would be if they could do the study on a large group of women living in a college dormitory?

THAT would equal a large amount of time spent together on a constant basis!

Yeah, and men in dorms tended to jack it after Skinemax Friday Night After Dark, resulting in clogged toilet systems.

doesn't that mean you only have to deal with it one time a month instead of four?

Yeah, period-tracking apps are okay, but is the inconvenience of having to keep a smart phone up your hoochie taken into account?
Data from my masturbation apps, on the contrary, show great cyclical synchronization amongst jerk-offs and fap addicts of all stripes and across all 58 genders, and they are also less intrusive strap-on models that make the genitals comfortable and more attractive for greater scientific accuracy of measurement, you see.

Most cycles have constant mesh gearboxes and don't require synchronizing.

The way they interpreted the data seems flawed...  they compared friends cycles to friends cycles over three
Months...

You should compare friends cycles to strangers cycles.

Bull. Shiat. I worked in call centers for years, with about a 10:1 ratio of women to men. They synch up in every way possible. Some of the older ones even looked and dressed just like each other. It was like some kind of passive hive mind at work.

Yeah, fark Live Science. That website's almost as bad as IFLscience.

DNRTFA, but if they didn't compare before/after groups, roommates who previously didn't know each other, roommates who had been friends beforehand, actual statements from the same women about the timing before and after, and only went for 3 months, it's about what I'd expect from that site.

This is more complex than a simple 3 cycles can cover and needs a far broader study than a few friends. For example, you could have close friends who went in to be roommates who didn't see much change,  if any, because they had already spent so much time together that they were cycling on a similar schedule before.

And if they didn't study women who were actually living together, then they failed there, too.

When I heard about this, I was in college, and it was in reference to women who were rooming together in the dorms. Not just sharing a residence but a small area with a shared bedroom. TFA says it (well, not their study but a A study) included lesbians living together, which would indeed match that level of closeness, but it also muddies the waters by including

some type of close relationship with the other person in the pair - they were friends, siblings, roommates, partners, mother-daughter pairs or colleagues. The researchers only included pairs who lived in the same city as each other, and about one-third of the pairs lived together.


So the majority of them weren't cohabitating at all, never mind sharing a cramped little dorm room with two or three women crammed in a one-room 100 square foot living space. That's a little different from "oh we're friends, we get together at least twice a week for lunch!" or even "yes, we live together. In a 1000 square foot apartment, with separate bedrooms".

I'm not married to the idea of synchronizing periods, just saying that TFA isn't exactly conclusive. In fact, there's an argument to be made for what TFA says took place - diverging period timing rather than converging. Why should they want to be fertile at the same time? Spread it out so they're not all competing for reproduction at the same time.

There's evolutionary pressure for cycles to get out of sync.  If most women sync up, but one woman doesn't, then that woman is more likely to get pregnant on certains days of the the synced up cycle.  She'll have more children who have unsynced up cycles, and soon everyone is out of sync.

The only way synced up cycles could exist is if there is some other, stronger, evolutionary pressure for them to sync.  That might happen in species with less marginal excess energy, where mating comes at a more severe cost, but with humans that seems pretty unlikley.

Didn't the first rumour about this come about from nuns in convents? No-one getting pregnant in those places (all right, it's not impossible, it's not unknown, but it's rare compared to the general population).

Not necessarily. If there's no significant negative pressure, then it might just be that it's a side effect of some other mechanism. Not everything has to be evolutionary.

I don't trust an article that doesn't base its thesis on tweets picked from within the author's circle of friends/coworkers.

I wonder if it is more advantageous for reproduction to have your cycle be in sync with nearby females, or to be out of sync.

When it finally hits, the beer is for him, and he passes out the 4 ice creams.  Smart.  Very smart.

In sync allows for wet nursing, which improves survival rate.  Synchronizing makes some sense.

Having all of the women be fertile all at the same time would make it harder for one male to impregnate everyone.  He wouldn't have time to fit into all of their *ahem* reproductive windows.  In theory, that would help to encourage genetic diversity and would lead to less inbreeding in close populations.
