Dear BDD Addicts,

November started with an unusually warm weather and brought a considerable increase of the virus spread that has been followed by stricter restrictions in most of the countries. At the HUSTEF conference where I was a track chair someone showed the Cynefin model, which classifies domains into chaotic, complex, complicated and obvious ones. And there is also a confusion area where we don’t even know where we are. So where are we now? Are we able to make well-prepared experiments and evaluate the results about COVID? This would be required to get to the complex phase.
