My guess is that the flat side provides a better surface for distributing pressure so long as the thing you are wrapping isn't a porcupine.

I think it's simpler than that. Bubble wrap the wrong way round means the only air cushioning is provided by the bubbles, and all the space between the bubbles is just a thin layer of plastic flat on the object that needs protection. Bubble wrap the right way round means the object is air-cushioned from the outside by both the bubbles themselves and the space between them (with the added bonus of the wrapping keeping a flatish outside surface).

Only the bubbles inside, flat-outside prevents direct, non-cushioned impacts

It always has been.

This is about the secondary use case, namely in packaging.

If you like to pop the bubbles the correct orientation is indeed the one you‘ve been using all along: bubbles towards your fingers.

I am ironically disappointed to learn that I have always been using bubble wrap correctly.

If it makes you feel better, I can tell you that using any form of plastic for shipping safety is bad and you should feel bad about it, because we have better alternatives like paper or even mycelium-based packaging matreials?

Thank you for your attempt to make me feel better, I would be truly devastated to learn that information if I were in the business of shipping fragile items in plastic bubble wrap, and that devastation would certainly assuage my current disappointment. Unfortunately I am not in that business and cannot even remember the last time I bubble-wrapped anything, so I cannot take any morally-masochistic solace from learning about the better alternatives. My disappointment remains immeasurable, but I will keep that info in mind in case I ever need it.

Summary: Bubbles should face inward. Article lacks evidence to support its titular claim that most instances of bubble-wrapping, or most bubble-wrapping wrappers, face the bubbles outward.

Reason says the bubbles should go on the inside:

There are gaps between the bubbles. If they're on the outside, something can impact the item in a gap and bypass the padding. If the bubbles are on the inside, they become supports for the flat side (which, IIRC, is usually heavier plastic), so if there's an impact on a gap, there's still padding because the plastic is being held away from the item and the force is transferred to the surrounding bubbles.

Correct. My point was that there is no evidence that most people do it wrong, as the title suggests.

Bubble envelopes are all wrong? Flipped bubbles would make it harder to slide objects in and out of the envelope, but they would reduce movement inside the envelope.

The difference seems minor other than the ability to tape the flat side, and we have cling bubble wraps that don't need tape anyway.

Yup. It's obvious they go on the inside, so how many people are actually putting them on the outside apart from imaginary ones used to justify a clickbait post?
