Maybe this explains the last election
If, as quantum mechanics says, observing the world tends to change it, how is it that we can agree on anything at all? Why doesn’t each person leave a slightly different version of the world for the next person to find? Â
Because, say the researchers, certain special states of a system are promoted above others by a quantum form of natural selection, which they call quantum darwinism….If it wasn’t for quantum darwinism, the researchers suggest, the world would be very unpredictable: different people might see very different versions of it.
