It really is required reading to get the most out of what I’m going to talk about in this post.
I had always planned to write about this most important topic soon enough, but the recent study out of Harvard’s School of Public Health generated more than enough stories like this one such that I figured it was worth putting some of my other ideas on the back-burner, at least for a week.
You’ve had great success improving your health on a vegan diet? It’s that pesky of experiments and they are not all equally effective at determining the cause and effect relationship.
Climate scientists and social economists (like one of my favorites, Steven Levitt, whom I’ve been fortunate enough to spend a day with), for example, often carry out natural experiments. Because the “laboratory” they study can’t actually be manipulated in a controlled setting.
Witnesses told police Farah was told to leave a second time, but later began chasing several people and threw the knife at them.
A male witness confronted Farah about chasing people, at which point he threatened to kill that person and threw the knife to the ground.
“For the greatest enemy of truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic.
For a period of time, say 5 years, the scientists would observe the differences in child death rates from these two causes (accidental drownings and gunshot wounds).
At the conclusion, provided the study was powered appropriately, the scientists would know which was more hazardous to the life of a child, a home swimming pool or a home gun.
The call followed “odd behavior” by Farah earlier that day, the local newspaper reports.
According to an eye witness, Farah was eating raw beef with the knife and holding it out to patrons, asking them to “play games.” Farah was asked to leave the area, which he did, only to return pointing the same knife at people as he spoke with them.
