I’ve also been reflecting on our decision to stay in place for Isaac. Was it the right choice? There’s room for disagreement even in our house. Over the past week Xy has repeated “Never again!” whereas I’ve found myself saying I’m glad we stayed.
So what were the pros and cons of that decision? It’s tempting, though foolish, to look at what actually happened.
For example: On the negative, the winds were kind of unsettling. None of us slept well that first night, when Isaac made his stumbling landfall not once but twice. Our whole house shook. Our house shakes whenever a truck rolls by, but sustained shaking for many hours is worrisome. Also, we were without power for four days. That was the worst of it.
Problem is, any analysis of our decision should be based on risk assessment, on what could have happened. To judge our judgment based on what actually happened is foolish — and irresistible, inevitable. Human nature, I suppose.
A tree could have fallen on our house. But it didn’t.
What’s the worst that might have happened? Here’s one nasty scenario: Hurricanes can spin off tornadoes faster than a late-70s sitcom. In fact Isaac was responsible for some tornadoes in Illinois. Tornadoes, to me, seem like tiny superfast hurricanes, much more unpredictable, highly destructive though much more limited in scope. So, a tornado could have hit our house in just such a way as to make it collapse and kill us all. I have no idea of the statistical likelihood of such an event. It would be interesting to compare that to the risk involved in, say, driving an automobile on the interstate.
In the end, though, it doesn’t come down to a rational analysis of statistical data. As I talked to people about their various plans to evacuate or not, I found a lot of it had to do with their previous experience. The authorities warn us that every storm is different, yet we can’t help comparing to the last one. Some people had a bad time in the evacuation for Ivan, which experience led them to stay for Katrina. Our Gustav evacuation informed our decision for Isaac.
I’m worried that going forward I’ll have an overly rosy memory of Isaac which will tempt me to stay at some point in the future when I really should go.
And so forth. There’s no escape from second-guessing.
