Statistical reasoning

Scientific facts
The chemical element Dihydrogen Monoxide (DHMO) can be very dangerous. We refer for example to this website. We confirm that, unfortunately, all reported information are correct, they are truthful scientific facts. Quoting from this reference: Each year, Dihydrogen Monoxide is a known causative component in many thousands of deaths and is a major contributor to millions upon millions of dollars in damage to property and the environment. Some of the known perils of Dihydrogen Monoxide are: - Death due to accidental inhalation of DHMO, even in small quantities. - Gaseous DHMO can cause severe burns. - Leads to corrosion and oxidation of many metals. - Found in biopsies of pre-cancerous tumors and lesions. The website asks you to sign a petition to ban DHMO. Would you consider signin the petition?

Interpreting statistical facts
We tell a true story, following this reference (which is an excerpt from the book How not to be wrong by Jordan Ellenberg). During the second world war, some airplanes made it back to the basis despite being full of bullet holes. The idea was protecting airplanes more and there was the choice as to which parts needed to be protected. The bullet holes were statistically concentrated on some parts of the airplanes. So the deliberation was to protect these very parts. Would you have voted for or against this deliberation, and why?
