I'm concerned on two fronts: 1) if quality of visual design is the thing being tested, then it might be more useful if the objective information in the two logos were the same. As it is, the difference here could be entirely attributed to the bingo card image being in one logo and not the other. (I know, the choice to put it in is a design decision, but it's useful to distinguish between testing the design/look-feel and the information in the logo) 2) I don't see in the write-up where brand confusion is accounted for here. What percentage of those shown the new logo had seen the previous one on a previous visit, and turned away because they thought they had the wrong site, or had otherwise diminished their view of the brand because of confusion?
