They cite work showing that "oral microbiota dysbiosis is significantly correlated with various neuropsychiatric disorders, including autism spectrum disorder, dementia, Parkinson’s disease, schizophrenia, anxiety, epilepsy, and depression."

No claims are made that oral microbiota cause depression and anxiety. I find it easy to believe that after marriage, couples converge in depression and anxiety absent any kissing. And because of kissing, their oral microbiota will also converge. But that doesn't imply that kissing is the cause of the convergence in depression and anxiety. Maybe I am missing something.

After reading I’m confused how oral bacteria is shown to be the cause. What I’m reading is that moving in with a depressed person is depressing.

It appears they didn't control for folks who lived together or had begun open-mouth kissing before marriage. Am I missing something?

This is in Iran, so presumably there’s less of that than in other places in the world?

Not to mention how difficult it can be to transition to sleeping with a bed partner, let alone one who is an insomniac.

"It can be argued that deriving a conclusive understanding from our preliminary findings is challenging without controlling for confounders (e.g., shared diet, stress exposure, and frequency of intimacy)." Seems like "stress exposure" is doing a lot of work there.

The study says sleep quality is also affected. I have doubts about this transmission mechanism, but it is an idea made for speculative fiction with a Gothic tinge. It's like a light version of vampirism without the blood: they kiss you [1], and you become morose and nocturnal.

[1] For a while, which admittedly spoils the image.

Study was performed in Tehran, Iran. I dunno - I see my feelings I instinctively question the quality of work in repressive countries.

Unlike in “free” countries where you definitely pinky-swear do not have politics or corporations manipulate research.

in free countries you're free to point out the corrupting influences of those you feel are corrupting research, and to do your own, and then disprove incorrect things

in Iran you don't say anything the Ayatollah disagrees with, or they kill you. Glory be to God.

It's a false equivocance to say there is no difference simply because free countries aren't perfect, and because all people have biases

In free countries you still need funding to do research and they won’t give it to you if you want to study something they don’t want you to. The result is the same.

The result is not the same.

In free countries there are many 'they' that can fund research. And 'they' can fund it without fear of the government.

It's not perfect but until we're post resource scarcity it's probably the best we can do.

In a free country there are a lot of "theys" with different views who might give you money, and you are also free to start a business and create your own wealth since private property is part of what makes a free country free.

In a country like Iran "they" must, by law, be aligned with the Ayatollah. That's the difference.

Free countries aren't perfect but at least the law gives these rights; in Iran they are explicitly given to the Church instead.

You're making a patently absurd argument based on completely overblown cynicism

If you do research independently without the backing of a prestigious university and/or corporation your research won’t be taken seriously and it will be impossible to have it published, which is as good as not doing it in the first place.

That's just so blantly weird stance.

What's your thought process? People in Iran should not kiss each other in marriage?

Repressive countries tend to dislike scientific research, especially domains who are remotely involved with the theory of evolution when the regime is theocratic.

Not to mention any study involving romantic things.
