Earlier quoted context omitted.

A perfect model for democracy I would say.

The flaw is that it forces someone into a role they do not want to fulfil, that could see the occupant become resentful of those around them and act out of spite. The short answer is there is no perfect model, people will always be people.

I somehow expect that person wouldn't have become spiteful _just_ because of the election, so wouldn't get elected in the first place... but yeah, we only have bad or worse solutions.

The research results are an interesting find and good work. They indicate a clear need for more research. They aren't conclusive as is, at least with the limited info I found (I haven't found a papers archive from The Wolf Society 2022 conference, so I had to go by press articles). Sample size of 229 seems small, considering the diversity among wolf packs. For example, were these wolves from one state vs multiple states. Getting a larger sample size would be hard but not impossible if the study lasted a long time. Science is about building a stairway - 99% steps 1% momentous landings that built on all the steps before them. This work is a good solid step.

Bringing my comments over from the other submission:

Not just wolves. Toxoplasma infection also "may make people look more attractive to the opposite sex": https://www.earth.com/news/parasite-makes-infected-people-lo...

Is this because it increases risk-taking behavior? Who knows, but it's interesting that something with potentially significant health drawbacks may have enough benefits that it's evolved to coexist with us (up to 50% of people carry it).

Overall, it looks increasingly like microbes shape our behavior and emotional health: https://www.science.org/content/article/evidence-mounts-gut-...

Imagine how dystopian that would sound in humans, like some science fiction horror. "All the leaders are secretly infected by parasites". Sounds like interesting sci fi movie premise.

Culture can be seen as a symbiont for humans. Without infection, we are mere hunter-gatherers.

Culture is emergent behavior or a description of human behavior, it's not an external agent that becomes attached to humans, so the analogy really doesn't work.

I don't see anything in that article that makes the conclusion inevitable. It's a remarkable correlation for sure, but unfortunately it doesn't go beyond that. There's no pathway from infection to leadership (just a vague hypothesis that doesn't resemble the mechanism in rats and hyenas), and it doesn't look as if they looked at uninfected pack leaders. Perhaps pack leaders or strays eat more dead cat, or some other…

I haven't read the paper either, but I must say the operation of parasites as elements in complex biological super-systems is absolutely fascinating. Ants that march to the top of trees under the influence of fungus spores trying to be eaten by birds. Fish that commit suicide by swimming toward predators as part of a parasitic lifecycle.... evolution is truly miraculous.

Another apocryphal story is cats carrying Toxoplasma Gondii make some people really like cats. So maybe mad cat lady syndrome is treatable with drugs :)

Who knows what super-systems we are unwittingly a part of. That seems an interesting area for big-data + AI hypothesis synthesis - we may find new explanations or even whole new branches of behaviour in psychology.

> Cassidy found that infected wolves were 11 times more likely than uninfected ones to leave their birth family to start a new pack, and 46 times more likely to become pack leaders

I thought we now believe that wolf packs are purely family units - mother, father and their cubs. There's no alpha wolves leading a pack of other male and female wolves, just stray wolves and family units. So a wolf pack is only comprised of the leader and its cubs.

I don't k ow anything about wolves or parasites, but those two things don't contradict each other. Maybe wolves with the parasite are exactly more likely to form such a family unit

Syphillis makes you artistically brilliant, gondi makes you fearless, never felt so good, then just before exitus. So, in conclusion, if the vector has requirements, the infection will try to make the host capable of fullfilment. If the infection needs sugar, the mitochondria, will make the amobea crawl to algea.

Thank you for the final line, I never realised that

Its all just thesis, nothing is proven yet.

It is how I read that. They start their faimilies. Alpha male/female = parents. A pack is their extended family.
