Correlated.org interests me. Scrolling down the front page, it's fun to try and form connections and explain correlations to yourself (probably wrongly).
Here are some of the ones on the front page I was able to think of a possible explanation for (many quite tenuous):
> among those who would be willing to observe a prison execution, 68 percent say they tend to stick to their decisions.
Sticking to your decisions might be a mark of social conservatism. In which case, being willing to observe someone being executed might correlate.
> among those who need corrective lenses to read, 54 percent prefer to play with dominoes as a tile game, rather than by toppling them
If it's myopia causing them to need glasses, well, myopia is apparently caused by not getting outside enough during childhood (and therefore not getting sufficient sunlight).
Perhaps, then, more active people would enjoy toppling dominoes more and have gotten outside more during youth (thus not developing myopia).
> among those who say that longevity runs in their family, only 26 percent like skim milk.
Maybe skim milk is a more recent thing, and people whose longevity 'runs in the family' would be more traditional? I'm really grasping at straws here.
> among those who use anti-dandruff shampoo, 54 percent say they are good Frisbee throwers.
Apparently dandruff can be caused by greasy skin (https://en.wikipedia.org/wiki/Dandruff#Causes) - is this more likely in more active people(?)
> among those who have recently done something dangerous enough that they had to sign a waiver, 73 percent find Irish accents to be especially attractive
I had two thoughts on this one:
1) Are people more likely to need to sign a waiver in certain countries? In which case, this might be a cultural thing.
2) People who've done dangerous things might be rather adventurous, and think Irish accents somehow symbolise that(??)
> among those who like the taste of honeysuckle nectar, 61 percent say their favorite kind of doughnut doesn't have a hole in it
Is honeysuckle nectar a sweet, fructosey thing? Well, doughnuts without holes often contain fruit jam. So someone who likes sweet, fruity things would be more likely to like both?
> among those who don't like couscous, 54 percent have witnessed an animal being born
People who live in the country are perhaps more likely to have witnessed an animal being born, right? (Though I suppose most people don't live on farms, hmm...) Since couscous is not a traditional foodstuff in the West, perhaps people living in the country, who are likely to be more conservative(?), would be less likely to enjoy couscous?
> among those who think that the only things that really exist are material things, 60 percent would prefer a messy roommate
This makes a certain intuitive sense to me, but I can't quite think of the words. The word 'hedonism' springs to mind, though might not quite be what I'm after.
> among those who find it hard to tolerate oscillating fans, 58 percent do the Electric Slide at wedding receptions
I wonder if this is a generational gap.
> among those who like raspberry vinaigrette salad dressing, 69 percent like candy corn
Like the honeysuckle nectar one, I suspect this is some common taste between the two foods.
