Interesting story, and I get the takeaway points. Can I confirm, though, how exactly the wine was arranged. For example:

“…six different bottles lined up in rows of two, with a label of A or B in front of each row. To clarify, there were a total of six different “brands” of wine with two columns of each brand, an A column or B column you could choose from.”

Are there six bottles, or twelve? I think twelve, right? With two rows, and 6 columns - one Column for each brand? (RowA and RowB, with ColBRand1, ColBrand2….ColBrand6) But elsewhere you refer to Column A & Column B. I think asking this question has cleared it up for me - but I think the article uses “Row” and “Column” almost interchangeably. Otherwise great article.
