A man is known by the company he keeps

I am not terribly sure how I manage to get into these situations – certainly level of IQ does not explain it – but recently I found myself in a great discussion on COVID and COVID expansion with a few luminaries. It was hosted by University of Virginia professor Dr. Madhav Marathe (under normal circumstances, I would kick that Dr. part – since he and I were college mates in Computer Science in IIT-M). The other luminary was Kiran Vaya – retired telecom executive from Motorola.

And then there was myself, trying to figure out how to spell “C-O-V-I-D”.

I have to say, I am amazed by how Madhav and Kiran were quickly able to draw the parallels between the spread of the virus and how cell packets are distributed thru the cellphone network. For whatever I remembered of Computer Science, that made amazing sense to me.

But what blew me away was Madhav (or should I say Dr. Marathe)’s explanation of why academia holds back from forecasting often. It is what he referred to as variables that are “endogenous” to the system.

If you did not get it in the first blush, count me in.

Here he what he explained lucidly to the audience…

Think of weather forecasting versus pandemic forecasting. Regardless of what the meteorologist forecasts, the weather is going to turn out exactly to be the same.

Not so for pandemic. The forecast of an outcome will change the behavior of the public – which will change the outcome itself!! That is a fascinating feedback-cycle!!

How do you forecast?

One thing I have learnt about great education. It is all about asking the right questions. Not necessarily having all the right answers.

Thank you Madhav and Kiran, I think I left the forum with a lot more questions than I had answers.

And that is the way it should be.
