Boys’ Versus Girls’ Trick-or-Treat Habits (continued)
The first experimental subject (unbeknownst to him) to arrive at my door was Darth Vader. On being offered the choice of a package or a big candy bar, he hesitated long enough for two other groups to pack up behind him. Then he picked the package. So did Tinkerbelle, a Space Man, and a small tiger with a painted face. The latter gave me my first statistical problem of the evening: was it a boy or a girl?
I guessed ‘boy’. But so far, EVERYONE had picked the package. What was I to make of this? The alternative was a big bar, a sure thing.
Lesson one: they had a bag full of candy. Regardless of the size, the bar was just more of the same. The package, however, represented a novelty, and was therefore more desirable – at least on this candy-crammed night.
Which is why my toothbrushes were received with great joy this Halloween, as I knew they would be.
But back to my study, which was beginning to show serious flaws besides the fact that gender is not always discernible when a child is in costume.
The next group was not so surprised to see the two baskets. Almost all the girls went for the packages. But half of the boys (I think they were boys) chose the candy bars. This trend intensified throughout the evening. by the time the last few items were gone, my chart was showing boys always choosing the sure thing, and girls always taking the risky package.
What was going on here?
So I threw scientific protocol to the wind and asked the next group. It seemed that the word was out all up and down the street that the big blue house was giving out something unusual. You see, the kids didn’t wait until they got home to open their packages—they tore them open as they walked, and everybody got to see. And then, if they didn’t like what they had, they tried to swap with somebody else.
What was skewing my results were all those girly items—particularly the makeup samples. The boy’s items were perfectly acceptable to a girl, but not so the reverse! And they couldn’t always be traded. So the boys quickly perceived it as a very risky choice – literally choosing between a sure – if overabundant – thing in the candy bar, or the 50-50 likelihood of getting the equivalent of a lump of coal in the stocking: the dreaded mascara sample! While the girls would get something unusual and fun, either way.
I can’t even remember what grade I got on my project, although I do remember it being the case-in-point for the Professor to discuss using controls and double-blind setups. But I did learn to think very hard about the context of a thing before coming to a conclusion on cause and effect.
