What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

If there’s anything we’ve learned from the coronavirus pandemic, it’s that washing our hands is one of the best ways to protect ourselves from the dangers of contagion. But hand washing does much more than cleanse us physically; sometimes it can wipe our mental slate clean. Here are some examples of what a bit of soap can do for our psyches.

Seems like most of them are small sample sizes. I'd like to see some repeatable results, too.

[–] [email protected] 4 points 3 days ago (1 children)

Indeed, it is a small sample size.

However, I think it’s possible that these results are true. If you understand relational frame theory, then you can see how the act of washing hands can activate some schemas or deactivate others.

Seen through this lens, the results of these experiments are not special, but are simply implications of an already established theory of cognition.

I respectfully disagree. The Germ Theory of Disease did not fully take root until the late 1800s, less than 200 years ago.

A fine example is Ignaz Philipp Semmelweis who proposed hand-washing for doctors because he noticed that there were fewer miscarriages and post-labor deaths when doctors washed their hands between an autopsy and a birth. This was, for one, against commonly accepted theory at the time, as the Germ Theory had not yet taken serious hold or had much evidence for it. For two, his proposal was later rejected, doctors stopped washing their hands, and Semmelweis was later committed into an asylum.

https://en.wikipedia.org/wiki/Ignaz_Semmelweis

The CDC in the USA didn't even suggest hand-washing for doctors until the 1980's.

https://www.ncbi.nlm.nih.gov/books/NBK144018/

The 1980s represented a landmark in the evolution of concepts of hand hygiene in health care. The first national hand hygiene guidelines were published in the 1980s, followed by several others in more recent years in different countries. In 1995 and 1996, the CDC/Healthcare Infection Control Practices Advisory Committee (HICPAC) in the USA recommended that either antimicrobial soap or a waterless antiseptic agent be used for cleansing hands upon leaving the rooms of patients with multidrug-resistant pathogens.

"Washing our hands of it" is a relatively recent phenomenon, seriously. If it was "simply implications of an already established theory of cognition" I would think that we'd have a much longer, serious history of actual handwashing. For most of human history, humans have been absolutely fucking filthy. Early human history didn't even use soap for bathing as much as it was used for textiles. Even the Romans, known for bathing, used oils, not soaps. Further, before the Industrial Revolution, soap was mostly accessible to the aristocracy. The Industrial Revolution was... *checks notes... was 1760, about a hundred years before Semmelweis was one of the first people to propose hand-washing.

This is an extremely short time period for this behavior to be part of "an already establish theory of cognition." Whereas we have millions of years without serious hand-washing as part of human culture... which is where that established theory of cognition was developed... prior to handwashing.

Ah. I see that it seems as if I’m saying that hand-washing is the result of a theory of cognition, and that this theory of cognition suggests that hand-washing has been deeply ingrained in our psyches for millenia, somehow eliciting the results from the experiments.

I am not suggesting that. Sorry for not having been clear before. I’m tired so I’m sorry if this response is not clear as well. I’m happy to clarify any further misunderstandings.

This is the theory that I’m referring to:

https://www.youtube.com/watch?v=GnSHpBRLJrQ (of course, there are academic publications on Relational Frame Theory, but this video shows its practical implications quite well)

Learn it in one. Derive it in two. Put it in networks, and that’s what you’ll do.

We have relational frames surrounding hand-washing. We also have relational frames for thousands of other thoughts and behaviors. When those two (hand-washing frames with other frames) combine, they can affect the way we think and act in ways that are novel and perhaps unusual.

Please let me know if this isn’t clear.
