Our universe holds magic. There's a rule
you only hear about in high school, though
ubiquitous as mankind's greatest fuel
for what prognostications state we know.
It's called the central limit theorem, best
seen through resulting curves we call a "bell".
Go sample something randomly in test,
then plot its frequency: the center swells.
When finite mean and variance exist,
a normal distribution oft results.
Do not forget poll averages consist
of this entire histogram. Insults
my brain when headlines cry black swan events
from polls sans intervals of confidence.
Thanks FiveThirtyEight for the inspiration.
