Privacy feels like such an innate desire. Your mention of parents going through your room brought back a few negative emotions tied to a few memories, where my mom either came to me with something she found in my room, or walked into my room and went directly to where something was hidden and pulled it out (indicating that she had already been snooping in my room and found it). Thinking about it, I realized that's one of the reasons I started hiding things where my parents couldn't easily get to them, like in the rafters in the garage, or in various forts and hideouts I created in the neighborhood.

No imagine your parents tracking you going into the garage every time or to specific hideouts.

Privacy is in my opinion one of the most important human rights that exist and the most frequently diminished or ignored, especially around parent/kid relations. Hence why it is a part of the UDHR (universal declaration of human rights).

With regards to kid/parent relation we are often too lenient as a society. One good measurement that you can keep in the back of your head to judge a kids invasion of privacy is the following question "If this kid was suffering from abusive parents, would this allow the parent to intervene the kid reaching out?".

While I agree with your overall sentiment, surely you do accept that parenting necessitates a certain degree of privacy intrusion from the parent to the child? (Or a stronger claim, that parenting involves a degree of surveillance, and active, parent-initiated guidance and control.) An infant or a toddler requires a high degree of control and privacy intrusion, and that degree should decrease as the person matures. I think that is nearly evident, and the only aspect that people (and various schools of thought regarding childcare, education and in fact social systems) argue about is the shape of that curve; how fast should the level of surveillance and control decrease and how low should it drop?

Yes I agree it is required to a certain extend however at the same time I think the socially acceptable level is usually too much to the parents control of the child. The falloff could be quite strong in my opinion. It is a difficult balance but usually parents or adjacent persons don't even realize privacy violations are happening. It is a real problem for kids (and people trying to help them) in difficult and abusive situations.

I have seen famous influencer (parents) commonly say things like "If you live in my house I can go through your room any time I please.". I understand the sentiment and some kids and situations require that, however I think openly incentivizing others to do so or normalizing that is not right. Especially knowing that it can make reaching out of abused kids much more difficult.

The earlier you can accept that you'll be perceived as evil to your child for about a decade... the better your child's adulthood will be, and the likelier you'll have mentally healthy great grandchildren.

Interesting take!

Both of my parents grew up in very small houses with a lot of children, and my wife shared a room with her sister. I'd guess that the vast majority of humanity now, and certainly in the past, had very little individual privacy because there was no room!

It seems like a modern luxury in western suburban living. Nice if if you can get it, I suppose.

Western. Lol

I think there’s a difference between privacy being a challenge (your example) versus a situation where privacy is actively undermined and disrespected (OP’s example).

It’s like accidentally ending up in the background of someone’s photo at a public park versus someone actively following and taking photos of you.

I think that in a lot of cases you will find that especially if physical privacy is not able to be maintained (small room that needs to be shared). There will be additional space (respect) that will be created for mental privacy.

In the past or in communities today where physical privacy is not always possible you will find there are a lot more accepted ways for people to separate themselves. Third spaces where you can be uninfluenced by the other party will be more common, going out for dinner alone or to the park alone are examples of activities that will be more normalized in those communities.

Your parents could probably be out the whole day without being tracked or recorded fully. However the modern day surveillance (including tracking of kids) means you will be tracked everywhere. You don't have the luxury anymore of going somewhere anonymous.

Ask your parents what they did when their sibling annoyed them.
