"This is an extremely poorly designed experiment...blah blah blah"
What are you talking about? The experiment is simply to find out what proportion of what handed people clasp their hands which way. Your little "insight" about how a certain thumb gets on top was brilliant...and obvious to my infant daughter. It's the point of the experiment, hich is not poorly designed; it is merely straightforward and simple.
I am so delighted that your infant daughter is a genuine genius following in your footsteps. After taking the "test" I simply noticed that depending on the position of my elbow, what I was doing prior to clasping and myriad other details including relative hand size and whether the gripping was initiated as thumb to thumb ( top) or pinky to pinky had more to do with the ultimate thumb position than my "handedness". Also there is a third and fourth positioning , again depending on prior extremity positioning and prior activity that is not listed. I am so very sorry to insult your superior brilliance with such mundane questions. After all science must not question and explotre in depth but skim the surface of junk science as is practiced in the schools and the poorly executed Science Fairs. Recovering from the flu led me to sift through FR again after several years absence...now I remember the reason for the absence , an intolerance for the inane.
