Quotations
"I have found it intriguing to narrate the history of statistics as viewed from the special lens of its orphaned sister: causation. The story of this 'forbidden love' was never told before and, believe me, it is full of mystery, intrigue, personalities, dogmatic orthodoxy, and heroic champions of truth and conviction."
[Vermont state] Rep. Van Wyck of Ferrisburgh explained his vote as follows: “Madam Speaker: I voted No. In college, I learned there were Lies, Damnable Lies, and then there is Statistics. I am not impressed with a number of these statistics.”

Forsooth
“That means then that criminal aliens are committing 28 percent of the crimes in the United States. And so that means 28 percent of the murders, 28 percent of the rapes, 28 percent of the violence and the assaults and battery, first- and second-degree murder and also manslaughter attacks are committed by criminal aliens.”
Never too early to start!

Comment on gerrymandering
Observing that Gerrymandering has been a hot topic in recent Chance News [see for example CN111, CN112, CN113], Emil Friedman sent the following comment:
Virtually any complex method we devise to combat Gerrymandering can probably be manipulated to partisan advantage. However, a simple way to make partisan gerrymandering nearly or completely impossible would be a nationwide system wherein we divide each state that is wider than it is tall (on a Mercator Projection) by vertical straight lines into contiguous vertical slices having nearly equal populations. States that are taller than wide would be divided horizontally instead of vertically. If adopted nationwide, it would make it impossible to rig the voting districts. However, a big downside is that it -- and almost any other solution involving a nationwide system -- would probably require a constitutional amendment.
