> 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.
