Pardon if this seems bit literal...
Shopping. Looking around the head, there are star ratings, a cart, dollar signs, and words of "customer reviews." Yes, the head is full of items, presumably purchased. So from this, I would assume several possibilities for accompanying articles, and I haven't looked yet.
- Tapping all the reviews in people's heads
- Shopping itself, and the process
- The process of purchasing, and special variants:
-- Effects of reviews
-- Loaded Reviews
-- Experience impacting purchasing
That said, all of the above likely falls short, and none of my ideas have the necessary twist, or spin, to make a NY Times article...
