A Buried Correction

If a paper corrects an article but people overlook it, does it make any difference?

Case in point: the Boston Globe, which corrected a commentary from last week:

A column on Saturday by Eyad al-Sarraj and Sara Roy incorrectly said that Gaza requires 680,000 tons of flour daily to feed its population. It is 680,000 pounds, which means a reduction of 73 percent, not 99 percent, of flour allowed into Gaza.

However, the text of the commentary itself wasn’t updated. The bad math is there for posterity while Globe editors assume everyone will find a correction buried at the very bottom of the page.
