Your first link mentions the Betty Crocker connection, but well into the article and only briefly. It also directly supports your first line objection. "Dichter did work with General Mills’ Betty Crocker brand, but that wasn’t till the 1950s. It's a tale even Michael Pollan falls for." Interestingly, after the cake mixes lost popularity, it was the frosting or icing, and magazine articles and books showing how to decorate cakes to look like works of art. So calling it the Betty Crocker Effect misses the real story on a couple of different levels. Creativity was the icing on the cake, as it were.
