Has there been a study about public phone usage without headphones?
This may be a silly question, but I've been wondering about the fairly recent shift into watching / listening to phones on full volume without headphones.
Is there a sociological explanation of why it has become so prevalent? Especially as it's cross-generational. It would make a little more sense if it was only Gen Z / Gen Alpha, because they grew up with phones and it would be more normalized. But it seems to be all ages, and I'm so curious how this shift happened.
It would never cross my mind to listen to my phone on full volume, or have a conversation on speakerphone for all to hear. It shocked me when it started happening, and I thought it was a few isolated incidents, but now I can't go a day without running into it. [For reference, I'm an elder millennial.]
Have any studies been done? Or is this too new?
