Lockdowns are as contagious as Covid
From our UK edition
Schools might never have closed in the first place had the coronavirus not started in China. Imagine it had started in Sweden. Whoever responded first was going to set the tone for the nations that followed. When we are uncertain about what to do, we look to the behaviour of others to guide us. Imagine walking down a street with a new restaurant on either side (you remember restaurants, right?), and that you do not know anything about either of them. One has some customers inside, the other has none. Assuming you can get a table, you would choose the one with people in it because, in the absence of any prior knowledge about the restaurants, other people provide you with a signal about which to eat in.
