You misread the statistics. And on top of that misread the particulars

> Take note, however, that in an update to that article made in 2010 and then in 2018, his firm’s eye tracking studies were showing that attention to information below the fold was much less focused. Specifically, information above the fold received 57% of a user’s viewing time and everything else — every “screenful of content” below the fold — received 17% or less.

Based on eye tracking, 57% of viewing time was "above the fold". And thus 43% was below the fold.

People spend more time looking above the fold, but pay more attention to what they see below the fold.

That's not what it says, it says "66% of attention happens below the fold" without specifying what that attention is on: seen above or below the fold.

It's definitely ambiguous, but the fold is the first page division. Once the viewer is on another page they can't be paying attention to a page that they are no longer on.

Later on I thought that the conflict between these statistics might be from different page sets shown to research subjects. Which would highlight the importance of page design (and content) in maintaining user attention (regardless of scrolling). If so, this point could have been clearer in the article.
