The high improbability of certain events
The extreme unlikelihood of certain events happening by chance
Swede reminded me in the comments below yesterday’s post that coincidences just happen, and I should just accept that or something is wrong with my mind. Sigh.
Indeed they do. I’ve had some crazy ones. For instance, when we lived in Bozeman our neighbors up the road, Mark and Cathy, asked if I was related to Tom Tokarski. Indeed I was, as my brother at that time lived just down the road in Livingston. But they were talking about another Tom Tokarski, one who was their neighbor in Indiana and who was a citizen activist fighting to stop the building of a road though a local undeveloped area.
What are the odds, with maybe five Tom Tokarski’s in the country, that Mark and Cathy would be neighbors with one in Indiana, and then move a thousand miles away to be neighbors with the brother of another one in Montana? Very long indeed, but just one of those things. We have all had coincidences like that in our lives.
In the posts linked above, I am not talking about that, but rather the statistical likelihood of related coincidences. When coincidences have an event or person or place in common, we can apply some basic math to determine probability. It’s the logic of the coin toss, that’s all.
Please do go read those posts if you are having trouble understanding why, for instance,
- Charles Peirce was able to detect that a will was a forgery, or
- Why it is extremely unlikely that FOUR hijackings would be successful on a given day, or
- It is so unlikely that a hijacker’s passport would survive and be found in the rubble even as no parts of the plane survived, or
- That the surveillance system at the Pentagon, along with the national air defense system, would go haywire on the very day that Vigilant Guardian, the biggest national air defense military drill of the year was running.
(I have not yet mentioned the seventeen military and civil defense drills that were running on 9/11/2001, and how they were intricately connected to the events of that day.)
In other words, if you don’t have a basic understanding of probability, this won’t register with you. If you do have that understanding, it will trouble you.
