About US
“Diaries During Lockdown” is a network of professionally trained mathematical modelers (along with some of their friends and colleagues) who are using the tools of system dynamics and systems thinking to explain many of the complex choices facing individuals, organizations, and governments as we collectively grapple with the COVID19 pandemic. The apparent voice of this story is that of David Andersen, a retired Professor of System Dynamics and Public Policy who lives on New Fadum Farm. This voice is actually the synthesis of a number of different analysts and writers.

A Road trip to North Carolina to Say “Goodbye” to Nancy
Deborah and David are very sad to learn that their very good friend, Nancy, has been diagnosed with a serious illness and is facing a poor prognosis. They consider making a road trip down to North Carolina to visit her. David runs some mental simulations of the risks posed by such a trip.

Confusion at our First “Regular” Dinner Party in a Year
Deborah and David intend to host a family dinner. They are now more than two weeks past their second vaccination, as are many of their friends and family members. Why is this all still so confusing?

What would happen to the pandemic if EGO were in control
In a moment of whimsy, David starts to think about what would happen if we had the ability to clearly specify how everyone must behave? Would it be possible to then behave in a way that would end the pandemic? Could human agency overpower this pandemic? Or is the pandemic stronger than we are collectively?
